前言

Arthas 是 Alibaba开源的Java诊断工具，具有实时查看系统的运行状况，查看函数调用参数、返回值和异常，在线热更新代码，秒解决类冲突问题、定位类加载路径，生成热点图，通过网页诊断线上应用。如今在各大厂都有广泛应用，也延伸出很多产品。

这里将介绍如何将Arthas集成进SpringBoot监控平台中。

SpringBoot Admin

为了方便SpringBoot Admin 简称为SBA

版本：1.5.x

1.5版本的SBA如果要开发插件比较麻烦，需要下载SBA的源码包，再按照spring-boot-admin-server-ui-hystrix的形式copy一份,由于JS使用的是Angular,本人放弃了

版本：2.x

2.x版本的SBA插件开发，官网有介绍如何开发，JS使用Vue，方便很多，由于我们项目还在使用1.5，所以并没有使用该版本，请读者自行尝试

不能使用SBA的插件进行集成，那还有什么办法呢？????

SBA 集成

鄙人的办法是将Arthas的相关文件直接copy到admin服务中

arthas包该包下存放的是所有arthas的Java文件

endpoint包下的文件可以都注释掉，没多大用
ArthasController这个文件是我自己新建的，用来获取所有注册到Arthas的客户端，这在后面是有用的
其他文件直接copy过来就行

@RequestMapping("/api/arthas")
@RestController
public class ArthasController {
 @Autowired
 private TunnelServer tunnelServer;
 @RequestMapping(value = "/clients", method = RequestMethod.GET)
 public Set<String> getClients() {
  Map<String, AgentInfo> agentInfoMap = tunnelServer.getAgentInfoMap();
  return agentInfoMap.keySet();
 }
}

spring-boot-admin-server-ui

该文件建在resources.META-INF下，admin会在启动的时候加载该目录下的文件

index.html 覆盖SBA原来的首页，在其中添加一个导航,首页会是这样

arthas.html 新建页面，用于显示arthas控制台页面

arthas.js 存储页面控制的js

var registerApplications = null;
var applications = null;
$(document).ready(function () {
    reloadRegisterApplications();
    reloadApplications();
});
/**
 * 获取注册的arthas客户端
 */
function reloadRegisterApplications() {
    var result = reqSync("/api/arthas/clients", "get");
    registerApplications = result;
    initSelect("#selectServer", registerApplications, "");
}
/**
 * 获取注册的应用
 */
function reloadApplications() {
    applications = reqSync("/api/applications", "get");
    console.log(applications)
}
/**
 * 初始化下拉选择框
 */
function initSelect(uiSelect, list, key) {
    $(uiSelect).html('');
    var server;
    for (var i = 0; i < list.length; i++) {
        server = list[i].toLowerCase().split("@");
        if ("phantom-admin" === server[0]) continue;
        $(uiSelect).append("<option value=" + list[i].toLowerCase() + ">" + server[0] + "</option>");
    }
}
/**
 * 重置配置文件
 */
function release() {
    var currentServer = $("#selectServer").text();
    for (var i = 0; i < applications.length; i++) {
        serverId = applications[i].id;
        serverName = applications[i].name.toLowerCase();
        console.log(serverId + "/" + serverName);
        if (currentServer === serverName) {
            var result = reqSync("/api/applications/" +serverId+ "/env/reset", "post");
            alert("env reset success");
        }
    }
}
function reqSync(url, method) {
    var result = null;
    $.ajax({
        url: url,
        type: method,
        async: false, //使用同步的方式,true为异步方式
        headers: {
            'Content-Type': 'application/json;charset=utf8;',
        },
        success: function (data) {
            // console.log(data);
            result = data;
        },
        error: function (data) {
            console.log("error");
        }
    });
    return result;
}

其他文件 jquery-3.3.1.min.js 新加Js

copy过来的js

popper-1.14.6.min.js

web-console.js

xterm.css

xterm.js

bootstrap.yml

# arthas端口
arthas:
  server:
    port: 9898

这样子，admin端的配置完成了

客户端配置

在配置中心加入配置

#arthas服务端域名
arthas.tunnel-server = ws://admin域名/ws
#客户端id,应用名@随机值，js会截取前面的应用名
arthas.agent-id = ${spring.application.name}@${random.value}
#arthas开关，可以在需要调试的时候开启，不需要的时候关闭
spring.arthas.enabled = false

需要自动Attach的应用中引入arthas-spring-boot-starter 需要对starter进行部分修改，要将注册arthas的部分移除，下面是修改后的文件。

我这里是将修改后的文件重新打包成jar包，上传到*，但有些应用会有无法加载arthasConfigMap的情况，可以将这两个文件单独放到项目的公共包中

@EnableConfigurationProperties({ ArthasProperties.class })
public class ArthasConfiguration {
 private static final Logger logger = LoggerFactory.getLogger(ArthasConfiguration.class);
 @ConfigurationProperties(prefix = "arthas")
 @ConditionalOnMissingBean
 @Bean
 public HashMap<String, String> arthasConfigMap() {
  return new HashMap<String, String>();
 }
}

@ConfigurationProperties(prefix = "arthas")
public class ArthasProperties {
 private String ip;
 private int telnetPort;
 private int httpPort;
 private String tunnelServer;
 private String agentId;
 /**
  * report executed command
  */
 private String statUrl;
 /**
  * session timeout seconds
  */
 private long sessionTimeout;
 private String home;
 /**
  * when arthas agent init error will throw exception by default.
  */
 private boolean slientInit = false;
 public String getHome() {
  return home;
 }
 public void setHome(String home) {
  this.home = home;
 }
 public boolean isSlientInit() {
  return slientInit;
 }
 public void setSlientInit(boolean slientInit) {
  this.slientInit = slientInit;
 }
 public String getIp() {
  return ip;
 }
 public void setIp(String ip) {
  this.ip = ip;
 }
 public int getTelnetPort() {
  return telnetPort;
 }
 public void setTelnetPort(int telnetPort) {
  this.telnetPort = telnetPort;
 }
 public int getHttpPort() {
  return httpPort;
 }
 public void setHttpPort(int httpPort) {
  this.httpPort = httpPort;
 }
 public String getTunnelServer() {
  return tunnelServer;
 }
 public void setTunnelServer(String tunnelServer) {
  this.tunnelServer = tunnelServer;
 }
 public String getAgentId() {
  return agentId;
 }
 public void setAgentId(String agentId) {
  this.agentId = agentId;
 }
 public String getStatUrl() {
  return statUrl;
 }
 public void setStatUrl(String statUrl) {
  this.statUrl = statUrl;
 }
 public long getSessionTimeout() {
  return sessionTimeout;
 }
 public void setSessionTimeout(long sessionTimeout) {
  this.sessionTimeout = sessionTimeout;
 }
}

实现开关效果

为了实现开关效果，还需要一个文件用来监听配置文件的改变
我这里使用的是在SBA中改变环境变量，对应服务监听到变量改变，当监听spring.arthas.enabled为true的时候，注册arthas, 到下面是代码

@Component
public class EnvironmentChangeListener implements ApplicationListener<EnvironmentChangeEvent> {
    @Autowired
    private Environment env;
    @Autowired
    private Map<String, String> arthasConfigMap;
    @Autowired
    private ArthasProperties arthasProperties;
    @Autowired
    private ApplicationContext applicationContext;
    @Override
    public void onApplicationEvent(EnvironmentChangeEvent event) {
        Set<String> keys = event.getKeys();
        for (String key : keys) {
            if ("spring.arthas.enabled".equals(key)) {
                if ("true".equals(env.getProperty(key))) {
                    registerArthas();
                }
            }
        }
    }
    private void registerArthas() {
        DefaultListableBeanFactory defaultListableBeanFactory = (DefaultListableBeanFactory) applicationContext.getAutowireCapableBeanFactory();
        String bean = "arthasAgent";
        if (defaultListableBeanFactory.containsBean(bean)) {
            ((ArthasAgent)defaultListableBeanFactory.getBean(bean)).init();
            return;
        }
        defaultListableBeanFactory.registerSingleton(bean, arthasAgentInit());
    }
    private ArthasAgent arthasAgentInit() {
        arthasConfigMap = StringUtils.removeDashKey(arthasConfigMap);
        // 给配置全加上前缀
        Map<String, String> mapWithPrefix = new HashMap<String, String>(arthasConfigMap.size());
        for (Map.Entry<String, String> entry : arthasConfigMap.entrySet()) {
            mapWithPrefix.put("arthas." + entry.getKey(), entry.getValue());
        }
        final ArthasAgent arthasAgent = new ArthasAgent(mapWithPrefix, arthasProperties.getHome(),
                arthasProperties.isSlientInit(), null);
        arthasAgent.init();
        return arthasAgent;
    }
}

结束

到此可以愉快的在SBA中调试应用了，看看最后的页面

调试流程

开启Arthas

在Select Application中选择应用

Connect 连接应用
DisConnect 断开应用
Release 释放配置文件

这种集成方式有一些缺陷：

使用jar包的方式引入应用，具有一定的侵略性，如果arthas无法启动，会导致应用也无法启动
如果使用docker，需要适当调整JVM内存，防止开启arthas的时候，内存炸了
没有使用SBA插件的方式集成
如上集成仅供参考，还是需要根据自己企业的情况来做
