如何通过annotations/pom.xml管理Maven配置文件? [英] How to manage maven profiles through annotations/pom.xml?

问题描述

Ref- Maven个人资料

---

我不想在运行时通过命令行参数指定配置文件.因为，如果我在本地进行更改，则必须在整个CI流中进行更改.

---

场景:

基本上有两个配置文件"PROD"和"TEST".我已经注释了使用这些方法.基本上，我在不同的配置文件下连接不同的数据库.

虽然测试类使用@ActiveProfile("TEST")

进行了注释

我使用mvn clean test-compile failsafe:integraton-test运行测试，并使用mvn springboot:run

运行应用程序

---

问题:

案例1:
问题:PROD和TEST仅运行与PROD相关的方法.

如果我不使用@Profile("PROD")，而仅使用@Profile("TEST")，并且使用参考中指定的@ActiveProfiles("TEST").上面两个未指定任何标志的mvn命令仅使用未用概要文件注释的Bean.
 

情况2:
问题:PROD无法运行.

如果我同时使用PROD和TEST而没有任何标志，则mvn clean test-compile failsafe:integraton-test命令运行完美(仅当指定了@ActiveProfile("TEST")时，否则我必须发送标志-Dspring.profiles.active=TEST)，但springboot:run不会无法工作，因为它无法获取任何数据库配置，也找不到活动的配置文件.

即使我同时使用PROD和@Primary注释PROD配置文件，情况仍然如此

令人惊讶的是，即使我提供了命令行参数，结果也是一样的. mvn springboot:run -Dspring.profiles.active=PROD

如果我注释使用@ActiveProfiles("PROD")运行这些配置文件的主类，则结果是相同的.
 

---

理想情况/预期:

最好使用不带标志的mvn test-compile failsafe:integration-test运行测试. (已经实现，但是产品不起作用)

要使用mvn springboot:run强调无标志的方式来运行产品.

---

首选更改:

Java注释:诸如@Profile，@ActiveProfile，@Primary之类的注释，它们告诉Spring-boot或maven使用什么.

POM.xml:设置配置文件以指导maven使用什么.

简而言之，我认为您只需要将spring.profiles.active=PROD添加到您的application.properties

我整理了一个示例，该示例打印出在prodant测试之间不同的bean内容，希望对您有所帮助.

运行以下代码时，我得到以下输出:

mvn spring-boot:run:上下文中的字符串为:PROD

mvn clean test:上下文中的字符串为:TEST

ProfilesApplication.java:

@SpringBootApplication
public class ProfilesApplication implements CommandLineRunner {

    Logger logger = LoggerFactory.getLogger(ProfilesApplication.class);

    @Autowired
    private String profiledString;

    public static void main(String[] args) {
        SpringApplication.run(ProfilesApplication.class, args);
    }

    @Bean
    @Profile("PROD")
    public String prodString() {
        return new String("PROD");
    }

    @Bean
    @Profile("TEST")
    public String testString() {
        return new String("TEST");
    }

    @Override
    public void run(String... args) throws Exception {
        logger.info("The String in the context is: {}", profiledString);
    }
}

application.properties:

spring.profiles.active=PROD

ProfilesApplicationTests.java:

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("TEST")
public class ProfilesApplicationTests {

    @Test
    public void contextLoads() {
    }
}

I don't want to specify profile through command line arguments while running. Because, if I change it locally, then changes have to be made thoughout CI stream.

---

Scenario:

There are basically two profiles "PROD" and "TEST". I have annotated methods using these. Basically, I connect different databases under different profiles.

While the test classes are annotated with @ActiveProfile("TEST")

I run tests using mvn clean test-compile failsafe:integraton-test and run application using mvn springboot:run

---

Problem:

Case 1:
Issue: Only PROD related methods run for PROD and TEST.

If I don't use @Profile("PROD") and only use @Profile("TEST") and I use @ActiveProfiles("TEST") as specified in reference. Both mvn commands without any flag specified above only use the beans which are not annotated with profiles.
 

Case 2:
Issue: PROD doesn't run.

If I use both PROD and TEST without any flag, mvn clean test-compile failsafe:integraton-test command runs perfectly (only when @ActiveProfile("TEST") is specified otherwise I'd have to send a flag -Dspring.profiles.active=TEST) but springboot:run doesn't work as it cannot pick up any database configuration and no active profile found.

This is the case even when I Annotate PROD profiles with both PROD and @Primary

Surprisingly even If I provide command line argument the result is the same. mvn springboot:run -Dspring.profiles.active=PROD

If I annotate the main class where these profiles are run with @ActiveProfiles("PROD"), the result is the same.
 

---

Ideal Scenario/Expected:

To run tests using mvn test-compile failsafe:integration-test preferably without flag. (Already acheived but prod isn't working)

To run prod using mvn springboot:run emphasis of no flags.

---

Preferable changes:

Java annotations: Annotations such as @Profile, @ActiveProfile, @Primary which tells Spring-boot or maven what to use.

POM.xml: setting profiles for directing maven what to use.

解决方案

in short i think you just need to add spring.profiles.active=PROD to your application.properties

I put together an example which prints the contents of a bean which differs between prod ant test, hope this helps.

When running the below code i get the following output:

mvn spring-boot:run: The String in the context is: PROD

mvn clean test: The String in the context is: TEST

ProfilesApplication.java:

@SpringBootApplication
public class ProfilesApplication implements CommandLineRunner {

    Logger logger = LoggerFactory.getLogger(ProfilesApplication.class);

    @Autowired
    private String profiledString;

    public static void main(String[] args) {
        SpringApplication.run(ProfilesApplication.class, args);
    }

    @Bean
    @Profile("PROD")
    public String prodString() {
        return new String("PROD");
    }

    @Bean
    @Profile("TEST")
    public String testString() {
        return new String("TEST");
    }

    @Override
    public void run(String... args) throws Exception {
        logger.info("The String in the context is: {}", profiledString);
    }
}

application.properties:

spring.profiles.active=PROD

ProfilesApplicationTests.java:

@RunWith(SpringRunner.class)
@SpringBootTest
@ActiveProfiles("TEST")
public class ProfilesApplicationTests {

    @Test
    public void contextLoads() {
    }
}
