获取“白标签错误页”运行执行器运行状况和映射URL

Question

我从Spring Boot开始，运行一个演示spring web starter项目，通过调用http://localhost:8080/mappings和http://localhost:8080/health来检查spring执行器的功能...它给我的是“白标签错误页”...日志没有显示任何内容

该项目是一个非常简单的启动应用程序，在STS中创建，使用一个运行良好的@RestController

主类：

@SpringBootApplication
public class DemoApplication {

    public static HashMap<Long,Student> hmStudent;

    public static void main(String[] args) {
        //dummt code
          SpringApplication.run(DemoApplication.class, args);
    }
}

Rest控制器：

import java.util.HashMap;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

import com.example.demo.DemoApplication;
import com.example.demo.entities.Student;

@RestController
@RequestMapping(value="/rest/student")
class StudentService{

   @RequestMapping(value="/",method = RequestMethod.GET)
   public HashMap<Long,Student> getAllStudents(){
      return DemoApplication.hmStudent;
   }
.
.
.
.
}

应用程序属性：

spring.datasource.url=jdbc:oracle:thin:@localhost:ibmwas
spring.datasource.username=u
spring.datasource.password=p
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver

Answer 1

从Spring Boot 2.0.0.release开始，所有endpoint的默认前缀都是/acture，所以如果您想检查应用程序的运行状况，应该转到/acture/healt

要使执行器endpoint通过HTTP可用，它需要同时启用和公开。

默认情况下：

启用了/shutdown以外的所有endpoint（仅公开/health和/info）

要公开所有endpoint，必须在application.properties中添加以下行：

management.endpoints.web.exposure.include=*
