java - 我的 InfoContributor 未向 Actuator 端点发送信息

Question

我正在尝试向 /info 端点发送更多信息:

@Component
public class InfoEndpoint implements InfoContributor {

    @Override
    public void contribute(Info.Builder builder) {
        Map<String, Integer> userDetails = new HashMap<>();
        userDetails.put("teste", 23);
        userDetails.put("teste2", 22);

        builder.withDetail( "menuitems", userDetails );
    }


}

但是访问http://myapp/actuator/info后我看不到该信息。为了进行一些测试，我在 application.properties 中放入了一些信息数据，例如 info.app.name，然后我只能看到这个。

我做错了什么？

Answer 1

在日志中我发现以下消息:

o.s.b.f.s.DefaultListableBeanFactory: Overriding bean definition for bean 'infoEndpoint' with a different definition: replacing [Generic bean: class [br.com.cmabreu.InfoEndpoint]; defined in file [C:\...\hydra\target\classes\br\com\cmabreu\InfoEndpoint.class]] with [Root bean: class [null]; factoryBeanName=org.springframework.boot.actuate.autoconfigure.info.InfoEndpointAutoConfiguration; factoryMethodName=infoEndpoint; defined in class path resource [org/springframework/boot/actuate/autoconfigure/info/InfoEndpointAutoConfiguration.class]]

看起来您的自定义 bean 已替换为默认 bean，因为它们具有相同的名称。一种解决方案是更改类的名称，例如:

@Component
public class ExtendedInfoEndpoint implements InfoContributor {
    Map<String, Integer> userDetails = new HashMap<>();
    userDetails.put("teste", 23);
    userDetails.put("teste2", 22);      
    builder.withDetail( "menuitems", userDetails );
}

另一个解决方案是使用属性的值:

@Component(value = "extendedInfoEndpoint")
public class InfoEndpoint implements InfoContributor {
    Map<String, Integer> userDetails = new HashMap<>();
    userDetails.put("teste", 23);
    userDetails.put("teste2", 22);      
    builder.withDetail( "menuitems", userDetails );
}
