스프링 부트 1.4 릴리즈 노트
스프링 부트 1.4 릴리즈 노트 - 2017년 1월 19일
원문: https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-1.4-Release-Notes
스프링부트 1.3이후 업그레이드된 것
스프링 부트 1.3에서 더이상 지원하지않는 것 Deprecations from Spring Boot 1.3
스프링 부트 1.3에서 디프리케이트된 클래스, 메소드, 프로퍼티들은 이번 릴리즈에서 제거되었다.업그레이드에 앞서 디프리케이트된 메소드를 호출하는지 먼저 확인해야한다.
Log4j 1 지원은 Apache EOL announcement 의거하여 제거되었다.
재명명된 스타터들 Renamed starters
다음의 스타터들의 이름이 변경되었다.기존의 이름은 스프링 부터 2.0에서 제거될 것이다.
spring-boot-starter-ws→spring-boot-starter-web-servicesspring-boot-starter-redis→spring-boot-starter-data-redis
DataSourceProperties의 get 메소드들 DataSourceProperties get methods
DataSourceProperties의 몇몇 get… 메소드들은 다른 @ConfigurationProperties 클래스들과 더 일관성있게 바뀌었다. 만약 이전에 다음의 메드들을 코드에 직접적으로 호출했었다면 동일한 기능의 새 determine…로 바꿔줘야한다.
getDriverClassName()→determineDriverClassName()getUrl()→determineUrl()getUsername()→determineUsername()getPassword()→determineUsername()
Note | The get메소드는 디프리케이트 되이 않았다. 하지만 이들의 행동이 바뀌었기때문에 당신은 업그레이드할때 수동으로 확인해줘야한다. |
DataSource 바인딩 DataSource binding
spring.datasourcenamespace. In 1.4, we only bind the common settings to spring.datasource (seeDataSourceProperties) and we have defined new specific namespaces for the four connections pools we support (in that order):DataSourceProperties 프링 부트 1.2에선 logging.config 를 써서 로깅 설정파일을 커스터마이즈할 수 있었다. 파일이 존스프링 부트 1.4 이전에는 자동설정된 datasource들은 spring.datasource 네임스페이스에 바인드되었다. 1.4부터 우리는 일반적인 설정만 spring.datasource에 바인드된다(DataSourceProperties를 보자) 그리고 우리가 지원하는 4개의 커넥션풀을 위한 새로운 특정 네임스페이스 정의하였다 (순서대로):org.apache.tomcat.jdbc.pool.DataSource를 위한spring.datasource.tomcatcom.zaxxer.hikari.HikariDataSource를 위한 spring.datasource.hikariorg.apache.commons.dbcp.BasicDataSource를 위한spring.datasource.dbcporg.apache.commons.dbcp2.BasicDataSource를 위한 spring.datasource.dbcp2
testOnBorrow 플래그를 사용하고 있다면, spring.datasource.test-on-borrow 에서 spring.datasource.tomcat.test-on-borrow로 옮겨줘야한다.만일 당신이 사용하는 IDE에서 설정을 도움받았다면, spring.datasource 네임스페이스에 이들을 모두 함께 사용하지않고 커넥션 풀당 어느 설정이 사용가는한지 볼 수 있다. 이는 어느 구현체가 어느 기능을 지원하는지 알아둬야 하는 당신의 삶을 더 쉽게 만들어줄 것이다.
JTA설정 바인딩 JTA settings binding
DataSource binding과 유사하게 Atomikos와 Bitronix 를 위한 특정 JTA제공자 설정 프로퍼티가 spring.jta에 바인드 된다. 이들은 이제 spring.jta.atomikos.properties와 spring.jta.bitronix.properties에 각각 바인드 될 것이다; 이들 엔트리를 위한 메타데이터 또한 크게 향상되었다.
하이버네이트 5 Hibernate 5
하이버네이트 5는 이제 기본 JPA 퍼시스턴스 제공자로서 사용된다. 만일 스프링 부트 1.3에서 업그레이드한다면, 하이버네이트 4.3에서 5.0으로 바꿔줘야한다. 일반적인 업그레이드 방침은 Hibernate migration documentation를 참고하자. 추가적으로 당신은 다음의 것들을 알아둬야한다:
네이밍 전략 Naming Strategy
하이버네이트 5.1이 이전의 NamingStrategy 인터페이스를 지원을 삭제함으로서 SpringNamingStrategy 는 더이상 사용되지 않는다. 새로운 SpringPhysicalNamingStrategy 가 이제 자동설정되어 하이버네이트의 기본 ImplicitNamingStrategy와 함께 사용된다. 이는 스프링부트 1.3의 기본설정과 매우 유사하다 (동일하진않다). 하지만 당신은 업그레이드시 데이터베이스 스키마가 올바른지 확인해주어야 할것이다.
만일 당신이 업그레이드 전 이미 하이버네이트 5를 사용중이라면, 아마 하이버네이트5의 기본설정을 사용하고 있을 것이다. 업그레이드 후에 이를 되돌리길 원하면 당신의 설정에 이 프로퍼티를 설정하면 된다:
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
제네레이터 매핑 Generator mappings
업그레이드의 고통을 최소화하기 위해, 우리는 하이버네이트5의 hibernate.id.new_generator_mappings을 false를로 설정해두었다. 하이버네이트 팀은 보통 이 설정을 권장하지않는다. 따라서 당신이 제네레이터 변경을 따르려면 당신의 application.properties 파일에 hibernate.id.new_generator_mappings을 true로 설정하면 된다.
하이버네이트 4.3으로 다운그레이드 Downgrading to Hibernate 4.3
하이버네이트 5.0으로 업그레이드하는데 문제가 있다면, pom.xml파일의 hibernate.version 프로퍼티를 오버라이딩함으로서 예전 버젼의 하이버네이트로 다운그레이드 할 수 있다.
<properties>
<hibernate.version>4.3.11.Final</hibernate.version>
</properties>또는 그레들을 사용한다면 hibernate.version 프로퍼티를 다음과 같이 오버라이딩하면 된다:
ext['hibernate.version'] = '4.3.11.Final'
Note | 하이버네이트 4.3 은 스프링부터 1.4에서 지원하지 않는다 업그레이드를 방해하는 버그가 있다면 이슈를 제기하자. |
@EntityScan
@org.springframework.boot.orm.jpa.EntityScan 어노테이션은 디프리케이트 되어 @org.springframework.boot.autoconfigure.domain.EntityScan 로 변경해주거나 외부 설정을 해주어야한다.
예를 들어 만일 다음의 설정을 가지고 있다면:
import org.springframework.boot.autoconfigure.SpringApplication;
import org.springframework.boot.orm.jpa.EntityScan;
@SpringBootApplication
@EntityScan(basePackageClasses=Customer.class)
public class MyApplication {
// ....
}만일 자동설정된 LocalContainerEntityManagerFactoryBean을 사용중이라면 다음과 같이 바꿔준다:
import org.springframework.boot.autoconfigure.SpringApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
@SpringBootApplication
@EntityScan(basePackageClasses=Customer.class)
public class MyApplication {
// ....
}또는 스스로 LocalContainerEntityManagerFactoryBean 을 설정중이라면, @EntityScan 어노테이션을 통째로 버리고 LocalContainerEntityManagerFactoryBean.setPackagesToScan(…) 를 호출하거나 또는 EntityManagerFactoryBuilder packages(…) 메소드를 사용해야한다:
@Bean
public LocalContainerEntityManagerFactoryBean entityManagerFactory(
EntityManagerFactoryBuilder builder) {
return builder
.dataSource(...)
.properties(...)
.packages(Customer.class)
.build();
}

}테스트 유틸리티와 클래스들 Test utilities and classes
스프링 부트 1.4는 org.springframework.boot.test 패키지를 완전히 재구성된 새로운 spring-boot-test 모듈을 추가하였다. 스프링 부트 1.3 어플리케이션에서 업그레이드할 때, 예전 패키지들의 디프리케이트된 클래스들을 새 구조의 동일한 클래스로 바꿔주어야한다. 리눅스 또는 OSX를 쓰고있다면 다음의 커맨드를 사용해서 코드를 마이그레잇할 수 있다:
find . -type f -name '*.java' -exec sed -i '' \

{} \;추가적으로, 스프링 부트 1.4는 스프링부트 테스트를 돌릴 수 있는 다양한 방법들을 더 합리적이고 간단하게 하려는 시도를 했다. 당신의 다음의 기존 코드를 새로운 @SpringBootTest 어노테이션을 사용하도록 바꿀수 있다:
기존 @SpringApplicationConfiguration(classes=MyConfig.class) 를 대체하는 새로운 @SpringBootTest(classes=MyConfig.class)
기존 @ContextConfiguration(classes=MyConfig.class, loader=SpringApplicationContextLoader.class)를 대체하는 새로운 @SpringBootTest(classes=MyConfig.class)
기존 @ContextConfiguration(classes=MyConfig.class, loader=SpringApplicationContextLoader.class) 를 대체하는 새로운 @SpringBootTest(classes=MyConfig.class)
기존 @IntegrationTest 를 대체하는 새로운 @SpringBootTest(webEnvironment=WebEnvironment.NONE)
기존 @IntegrationTest와 @WebAppConfiguration 를 대체하는 새로운 @SpringBootTest(webEnvironment=WebEnvironment.DEFINED_PORT) (또는 RANDOM_PORT)
기존 @WebIntegrationTest to@SpringBootTest(webEnvironment=WebEnvironment.DEFINED_PORT) (or RANDOM_PORT)
팁 마이그레션 테스트 진행간에 당신은 또한 기존 @RunWith(SpringJUnit4ClassRunner.class)
선언문들을 스프링 4.3의 더 가독성이 좋은 @RunWith(SpringRunner.class).로 대체할 수 있다.

TestRestTemplate
TestRestTemplate 클래스는 더이상 직접적으로 RestTemplate 에서 extends되지 않는다. (비록 여전히 같은 메소드를 제공하긴하지만). 이로서 TestRestTemplate 는 의도치않게 주입(accidentally injected)되는 일 없이 하나의 빈 Bean으로서 설정하는게 가능해졌다. RestTemplate 안에 실제 접근해야할 필요가 있다면 getRestTemplate() 메소드를 사용하자.

Integration Starter
spring-boot-starter-integration 은 일반적인 Spring Integration 어플리케이션에서 필요하지않은 4가지 모듈을 제거함으로서 간소화하였다. 제거된 4개의 모듈은 다음과 같다:
spring-integration-file
spring-integration-http
spring-integration-ip
spring-integration-stream
당신의 어플리케이션이 저 4개의 모듈중 하나라도 사용한다면 pom이나 build.gradle에 명시적 의존성을 추가해줘야할 것이다.
추가적으로, spring-integration-java-dsl 과 spring-integration-jmx 은 이제 스타터에 추가되었다. DSL을 사용하는것은 당신의 어플리케이션의 Spring Intergation을 설정할때 권장되는 되는 방식이다.

Spring Batch Starter
spring-boot-starter-batch starter 는 더이상 embedded 데이터베이스에 의존성을 갖지않는다. 당신이 기존의 방식대로 사용하고 싶다면 당신이 원하는 데이터베이스 (드라이버)를 추가해줘야한다. 예를 들면:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-batch</artifactId>
</dependency>
<dependency>
<groupId>org.hsqldb</groupId>
<artifactId>hsqldb</artifactId>
<scope>runtime</scope>
</dependency>이미 다른 드라이버를 설정하여 hsqldb 를 exclusion해두었다면 이젠 exclusion을 지워버려도 된다.

@ConfigurationProperties default bean names
When a @ConfigurationProperties bean is registered via@EnableConfigurationProperties(SomeBean.class), we used to generate a bean name of the form <prefix>.CONFIGURATION_PROPERTIES. As of Spring Boot 1.4, we have changed that pattern to avoid name clashes if two beans use the same prefix.
The new conventional name is <prefix>-<fqn>, where <prefix> is the environment key prefix specified in the @ConfigurationProperties annotation and <fqn> the fully qualified name of the bean. If the annotation does not provide any prefix, only the fully qualified name of the bean is used.

Spring Session auto-configuration improvements
Spring Boot supports more backend stores for Spring Session: alongside Redis, JDBC, MongoDB, Hazelcast and in memory concurrent hash maps are also supported. A newspring.session.store-type mandatory property has been introduced to select the store Spring Session should be using.

Launch script identity
When the launch script is determining the application’s default identity, the canonical name of the directory containing the jar will now be used. Previously, if the directory containing the jar was a symlink, the name of the symlink was used. If you require more control over the application’s identity, the APP_NAME environment variable should be used.

Executable jar layout
실행가능한 jars (executable jars)의 레이아웃이 변경되었다. 스프링부트의 메이븐, 그래들 또는 앤트지원을 통해 빌드한다면 이 변화는 영향을 미치지 않을 것이다. 당신 스스로의 실행가능한 아카이브를 통해서 빌드한다면 이제 어플리케이션이 lib이 아니라 BOOT-INF/lib 에 패키지 된다는 것을 명심하라. 어플리케이션의 클래스들은 이제 jar의 루트가 아닌 BOOT-INF/classes 에 패키지 될것이다.

Integration tests with the maven-failsafe-plugin
As of Failsafe 2.19, target/classes is no longer on the classpath and the project’s built jar is used instead. The plugin won’t be able to find your classes due to the change in the executable jar layout. There are two ways to work around this issue:
Downgrade to 2.18.1 so that you use target/classes instead
Configure the spring-boot-maven-plugin to use a classifier for the repackage goal. That way, the original jar will be available and used by the plugin. For example
<plugin>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-maven-plugin</artifactId>
<configuration>
<classifier>exec</classifier>
</configuration>
</plugin>
Note If you are using Spring Boot’s dependency management, there is nothing to do as you’ll use 2.18.1 by default.
Tip Watch SUREFIRE-1198 for updates on this issue.

Analysis of startup failures
Spring Boot will now perform analysis of common startup failures and provide useful diagnostic information rather than simply logging an exception and its stack trace. For example, a startup failure due to the embedded servlet container’s port being in use looked like this in earlier versions of Spring Boot:
2016-02-16 17:46:14.334 ERROR 24753 --- [ main] o.s.boot.SpringApplication : Application startup failed

Image Banners
You can now use image files to render ASCII art banners. Drop a banner.gif, banner.jpg orbanner.png file into src/main/resources to have it automatically converted to ASCII. You can use the banner.image.width and banner.image.height properties to tweak the size, or usebanner.image.invert to invert the colors.

RestTemplate builder
A new RestTemplateBuilder can be used to easily create a RestTemplate with sensible defaults. By default, the built RestTemplate will attempt to use the most suitableClientHttpRequestFactory available on the classpath and will be aware of theMessageConverter instances to use (including Jackson). The builder includes a number of useful methods that can be used to quickly configure a RestTemplate. For example, to add BASIC auth support you can use:
@Bean
public RestTemplate restTemplate(RestTemplateBuilder builder) {
return builder.basicAuthorization("user", "secret").build();
}
The auto-configured TestRestTemplate now uses the RestTemplateBuilder as well.

JSON Components
A new @JsonComponent annotation is now provided for custom Jackson JsonSerializer and/orJsonDeserializer registration. This can be a useful way to decouple JSON serialization logic:
@JsonComponent
public class Example {
public static class Serializer extends JsonSerializer<SomeObject> {
// ...
}
public static class Deserializer extends JsonDeserializer<SomeObject> {
// ...
}
}
Additionally, Spring Boot also now provides JsonObjectSerializer and JsonObjectDeserializerbase classes which provide useful alternatives to the standard Jackson versions when serializing objects. See the updated documentation for details.

Convention based error pages
Custom error pages for a given status code can now be created by following a convention based approach. Create a static HTML file in /public/error or add a template to/templates/error using the status code as the filename. For example, to register a custom 404 file you could add src/main/resource/public/error/404.html. See the updated reference documentation for details.

ErrorPageRegistry
New ErrorPageRegistry and ErrorPageRegistrar interfaces allow error pages to be registered in a consistent way regardless of the use of an embedded servlet container. TheErrorPageFilter class has been updated to that it is now a ErrorPageRegistry and not a fakeConfigurableEmbeddedServletContainer.

Test improvements
Spring Boot 1.4 includes a major overhaul of testing support. Test classes and utilities are now provided in dedicated spring-boot-test and spring-boot-test-autoconfigure jars (although most users will continue to pick them up via the spring-boot-starter-test"Starter"). We’ve added AssertJ, JSONassert and JsonPath dependencies to the test starter.

@SpringBootTest
With Spring Boot 1.3 there were multiple ways of writing a Spring Boot test. You could use@SpringApplicationConfiguration, @ContextConfiguration with theSpringApplicationContextLoader, @IntegrationTest or @WebIntegrationTest. With Spring Boot 1.4, a single @SpringBootTest annotation replaces all of those.
Use @SpringBootTest in combination with @RunWith(SpringRunner.class) and set thewebEnvironment attribute depending on the type of test you want to write.
A classic integration test, with a mocked servlet environment:
@RunWith(SpringRunner.class)
@SpringBootTest
public class MyTest {
// ...
}
A web integration test, running a live server listening on a defined port:
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment=WebEnvionment.DEFINED_PORT)
public class MyTest {
// ...
}
A web integration test, running a live server listening on a random port:
@RunWith(SpringRunner.class)
@SpringBootTest(webEnvironment=WebEnvionment.RANDOM_PORT)
public class MyTest {
@LocalServerPort
private int actualPort;
// ...
}

Auto-detection of test configuration
Test configuration can now be automatically detected for most tests. If you follow the Spring Boot recommended conventions for structuring your code the @SpringBootApplication class will be loaded when no explicit configuration is defined. If you need to load a different@Configuration class you can either include it as a nested inner-class in your test, or use theclasses attribute of @SpringBootTest.
See Detecting test configuration for details.

Mocking and spying beans
It’s quite common to want to replace a single bean in your ApplicationContext with a mock for testing purposes. With Spring Boot 1.4 this now as easy as annotating a field in your test with @MockBean:
@RunWith(SpringRunner.class)
@SpringBootTest
public class MyTest {
@MockBean
private RemoteService remoteService;
@Autowired
private Reverser reverser;
@Test
public void exampleTest() {
// RemoteService has been injected into the reverser bean
given(this.remoteService.someCall()).willReturn("mock");
String reverse = reverser.reverseSomeCall();
assertThat(reverse).isEqualTo("kcom");
}
}
You can also use @SpyBean if you want to spy on an existing bean rather than using a full mock.
See the mocking section of the reference documentation for more details.

Auto-configured tests
Full application auto-configuration is sometime overkill for tests, you often only want to auto-configure a specific "slice" of your application. Spring Boot 1.4 introduces a number of specialized test annotations that can be used for testing specific parts of your application:
@JsonTest - For testing JSON marshalling and unmarshalling.
@WebMvcTest - For testing Spring MVC @Controllers using MockMVC.
@RestClientTest - For testing RestTemplate calls.
@DataJpaTest - For testing Spring Data JPA elements
Many of the annotations provide additional auto-configuration that’s specific to testing. For example, if you use @WebMvcTest you can @Autowire a fully configured MockMvc instance.
See the reference documentation for details.

JSON AssertJ assertions
New JacksonTester, GsonTester and BasicJsonTester classes can be used in combination with AssertJ to test JSON marshalling and unmarshalling. Testers can be used with the@JsonTest annotation or directly on a test class:
@RunWith(SpringRunner.class)
@JsonTest
public class MyJsonTests {
private JacksonTester<VehicleDetails> json;
@Test
public void testSerialize() throws Exception {
VehicleDetails details = new VehicleDetails("Honda", "Civic");
assertThat(this.json.write(details)).isEqualToJson("expected.json");
assertThat(this.json.write(details)).hasJsonPathStringValue("@.make");
}
}

Auto-configuration for Spring REST Docs
Combined with the support for auto-configuring MockMvc described above, auto-configuration for Spring REST Docs has been introduced. REST Docs can be enabled using the new @AutoConfigureRestDocs annotation. This will result in the MockMvc instance being automatically configured to use REST Docs and also removes the need to use REST Docs' JUnit rule. Please see the relevant section of the reference documentation for further details.

Spring Data "Ingalls" release train support
Spring Boot 1.4 GA ships with the Spring Data "Hopper" release out of the box. Users that would like to try the "Ingalls" release train (available in milestone one at the time of writing) can do so by just setting the spring-data-releasetrain.version property to Ingalls-M1 and declaring the Spring milestone repository.
Depending on what modules of Spring Data you use, you might have to upgrade a couple of transitive dependencies, too:
Spring Data REST users will have to upgrade to Spring HATEOAS 0.21 (set spring-hateoas.version to 0.21.0.RELEASE)
Spring Data Redis users using Jedis as driver will have to upgrade to 2.9 (setjedis.version to 2.9.0)
