SpringBoot 自定义Starter

Starter项目 1.创建项目 2.引入需要的依赖

<dependencies>
  <dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-autoconfigure</artifactId>
    <version>2.6.7</version>
  </dependency>
</dependencies>

3.新建项目目录

4.新增类 新建TestDemo DTO

/**
 * TestDemo
 * */
public class TestDemo {
    /**
     * 名称*/
    private String name;

    public String getName() {
        return name;
    }

    
    public void setName(String name) {
        this.name = name;
    }
}

新建配置文件 TestDemoProperties Properties

/**
 * 属性
 * */
@ConfigurationProperties(prefix = "demo")
public class  TestDemoProperties {
    /**
     * 是否启动
     * */
    private boolean enable;
    /**
     * test属性
    * */
    private String test;

    public boolean isEnable() {
        return enable;
    }
    public void setEnable(boolean enable) {
        this.enable = enable;
    }
    public String getTest() {
        return test;
    }
    public void setTest(String test) {
        this.test = test;
    }
}

新建TestDemoService Service

/**
 * TestDemo
 * */
public class TestDemo {
    /**
     * 名称*/
    private String name;

    public String getName() {
        return name;
    }


    public void setName(String name) {
        this.name = name;
    }
}

新建自动配置文件 TestDemoAutoConfiguration

/**
* 自动配置类
* */
@Configuration
@ConditionalOnClass(TestDemoService.class) //判断是否存在TestDemoService
@ConditionalOnProperty(prefix = "demo", value = "enable", matchIfMissing = true)  //判断firststarter.enable属性是否为true
@EnableConfigurationProperties(TestDemoProperties.class)
public class TestDemoAutoConfiguration {


    /**
    * 获取TestDemoService
    * */
    @Bean
    @Order
    @ConditionalOnMissingBean
    public TestDemoService testdemoService() {
        return new TestDemoService();
    }
}

新建配置文件

resources/META-INF/spring.factories

org.springframework.boot.autoconfigure.EnableAutoConfiguration=\
com.ausion.configuration.TestDemoAutoConfiguration

 

调用Starter项目

引入依赖

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-web</artifactId>
    <version>2.6.7</version>
</dependency>
<dependency>
    <groupId>com.ausion</groupId>
    <artifactId>demo</artifactId>
    <version>1.0-SNAPSHOT</version>
    <scope>compile</scope>
</dependency>

 

新建yaml

demo:
 enable: true
 test: 123456

新建Controller

@RestController
public class TestController {
    @Autowired
    private TestDemoService testDemoService; //引入自定义Starter中的testDemoService

    @RequestMapping("/test")
    public String addString(){
        return testDemoService.Test();
    }
}

结果
