15.1 设计自己的状态检查

package com.clsaa.edu.springboot;

import org.springframework.boot.actuate.health.Health;
import org.springframework.boot.actuate.health.HealthIndicator;
import org.springframework.stereotype.Component;

/**
 * Created by Egg on 2017/2/27.
 */
@Component
public class MyHealthIndicator implements HealthIndicator {

    @Override
    public Health health() {
        return Health.down().withDetail("1","2").build();
    }
}

15.2 监控某一个URL被用了多少次

-使用CounterService进行计数

• counter.user.home.request.count:2

package com.clsaa.edu.springboot;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.metrics.CounterService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Egg on 2017/2/27.
 */
@RestController
public class UserController {
    @Autowired
    private CounterService counterService;
    @GetMapping("/user/home")
    public String home(){
        counterService.increment("user.home.request.count");
        return "home";
    }
}

15.3 为某个监控参数设置值

package com.clsaa.edu.springboot;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.actuate.metrics.CounterService;
import org.springframework.boot.actuate.metrics.GaugeService;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;

/**
 * Created by Egg on 2017/2/27.
 */
@RestController
public class UserController {

    @Autowired
    private GaugeService gaugeService;
    @Autowired
    private CounterService counterService;
    @GetMapping("/user/home")
    public String home(){
        counterService.increment("user.home.request.count");
        return "home";
    }

    @GetMapping("/mp3/price")
    public String price(@RequestParam("price") double price){
        gaugeService.submit("mp3.price",price);
        return "mp3 price";
    }
}
