自定义 springboot starter

• 创建自定义的service处理逻辑类(不能加载到spring ioc中去)

  public class UserService {
      @Autowired
      private HelloFeignService helloFeignService;
  
      @Autowired
      private RestTemplateService restTemplateService;
  
      public String getNew(String id) {
  
          String hello = helloFeignService.hello(id);
  
          return "getNew " + hello;
      }
  
      public String getNewex(String id) {
          return restTemplateService.findone(id);
      }
  }

• 自定义配置类

  
  @ConfigurationProperties(prefix = "demo")
  public class MyConfigProperties {
      private String name;
  
      private int age;
  
      public String getName() {
          return name;
      }
  
      public void setName(String name) {
          this.name = name;
      }
  
      public int getAge() {
          return age;
      }
  
      public void setAge(int age) {
          this.age = age;
      }
  }
• autoConfig配置类

  @Configuration
  @EnableConfigurationProperties(MyConfigProperties.class)
  @ConditionalOnProperty(prefix = "demo", name = "is-open", havingValue = "true")
  public class AutoConfigStarter {
      @Autowired
      MyConfigProperties myConfigProperties;
  
      @Bean
      public MyService myService() {
          return new MyService(myConfigProperties.getName(), myConfigProperties.getAge());
      }
  }

   
•  最后加上autoConfig配置          在目录META-INF下面创建spring.factories

  org.springframework.boot.autoconfigure.EnableAutoConfiguration=home.spring.cloud.service.AutoConfigStarter
