获得"Whitelabel错误页面"运行执行器运行状况和映射网址

Question

我开始使用spring boot,运行一个demo spring web starter项目,我通过调用http:// localhost:8080/mappings和http:// localhost:8080/health来检查弹簧执行器功能 ...它给了我"Whitelabel错误页面"...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,其中一个@RestController工作正常

主要课程:

@SpringBootApplication
public class DemoApplication {

    public static HashMap<Long,Student> hmStudent;

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

休息控制器:

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

问题是什么？如何使日志更具描述性

Answer 1

从Spring Boot 2.0.0.RELEASE开始,所有端点的默认前缀都是/actuator 如此.如果你想检查一个应用程序的运行状况,你应该去/actuator/health

要通过HTTP提供执行器端点,需要同时启用和公开.

默认情况下:

• 只有/health和/info端点被暴露.

• 所有端点但/shutdown已启用(仅显示/ health和/ info)

要公开所有端点,您必须将以下行添加到application.properties:

management.endpoints.web.exposure.include=*
