Springboot入门之集成Actuator_springboot集成actuator

1.Actuator是什么？

Actuator是spring boot下的一个模块，提供http (或JMX)端点来实现对应用程序的监视和管理、收集运行状况等功能。

2.添加相关依赖

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>

3.启动测试

http://localhost:8080/actuator

默认开放3个endpoint， /actuator /actuator/health /actuator/health/{*path}

4.开放endpoint 修改application.yml

management:
  server:
    port: 12345             # 端口默认=server.port 增加安全性
  endpoints:
    web:
      exposure:
        include: "*"        # 开放节点 * 开放所有 beans,.....
        # exclude: beans    # 禁止开放节点 * 禁止开放所有 beans,.....
      base-path: /control   # 自定义根路径  增加安全性
  endpoint:
    shutdown:
      enabled: true         # 打开shutdown端点 POST请求
    health:
      show-details: always  # 获得健康检查中所有指标的详细信息
    beans:
      cache:
        time-to-live: 100s  # 不带参数的端点请求会自动进行缓存
  #health:
    #defaults:
      #enabled: false       # 禁用所有自动健康检查
    #mongo:
      #enabled: false       # 禁用制定组件（mongo）自动健康检查

6.端点保护

6.1 添加依赖

       <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

6.2 添加配置

spring:
  security:
    user:
      name: admin
      password: admin
      roles: admin

6.3 配置拦截地址

package com.example.hellospringboot.config;
 
import org.springframework.boot.actuate.autoconfigure.security.servlet.EndpointRequest;
import org.springframework.boot.actuate.context.ShutdownEndpoint;
import org.springframework.boot.autoconfigure.security.servlet.PathRequest;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;
 
 
@Configuration
public class ActuatorSecurityConfig extends WebSecurityConfigurerAdapter {
 
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests()
                .requestMatchers(EndpointRequest.to(ShutdownEndpoint.class))
                .hasRole("admin")
                .requestMatchers(EndpointRequest.toAnyEndpoint())
                .permitAll()
                .requestMatchers(PathRequest.toStaticResources().atCommonLocations())
                .permitAll()
                .antMatchers("/control*")
                .permitAll()
                .antMatchers("/control**")
                .authenticated()
                .and()
                .httpBasic();
 
 
    }
}
