如果是Maven项目，则在pom.xml引入jar包
<dependency>
<groupId>org.apache.xmlrpc</groupId>
<artifactId>xmlrpc-client</artifactId>
<version>3.1.3</version>
</dependency>
封装SupervisorUtils工具包
/**
* Supervisor 方法封装
* @author Mr.Li
* @date 2023-05-30
*/
public class SupervisorUtils {
/**
* 执行supervisor控制命令
* @param url 服务地址
* @param username 用户名
* @param password 密码
* @param method 控制方法
* @param params 参数
*/
public static Object sendSupervisorCommand(String url,String username,String password,String method, Vector<Object> params){
try {
XmlRpcClientConfigImpl config = new XmlRpcClientConfigImpl();
config.setServerURL(new URL(url));
config.setBasicUserName(username);
config.setBasicPassword(password);
XmlRpcClient client = new XmlRpcClient();
client.setConfig(config);
return client.execute(method, params);
}catch (MalformedURLException e) {
e.printStackTrace();
return null;
} catch (XmlRpcException e) {
e.printStackTrace();
return null;
}
}
}参数详解
其中localhost为你的IP地址，如果是本地可以使用localhost,或者120.0.
这里的用户名密码是你在安装supervisor时，supervisor配置文件中[inet_http_server]下配置的远程控制界面的用户名与密码。
method是可以控制supervisor的方法，对应的清单如下：
/**
* Supervisor XML-RPC监控方法常量
* @author Mr.Li
* @date 2023-05-30
*/
public class SupervisorConstants {
/**
* 获取监控服务运行状态
* 返回SupervisorStruct实体类
*/
public static final String getState="supervisor.getState";
/**
* 关闭监控服务
* 返回boolean
*/
public static final String shutdown="supervisor.shutdown";
/**
* 重启监控服务
* 返回boolean
*/
public static final String restart="supervisor.restart";
/**
* 获取监控的所有进程信息
* 返回ProcessStruct[]集合
*/
public static final String getAllProcessInfo="supervisor.getAllProcessInfo";
/**
* 启动进程;
* 参数1:group:name(String);
* 参数2:wait:是否等待启动完毕(Boolean)
* 返回boolean
*/
public static final String startProcess="supervisor.startProcess";
/**
* 启动所有进程
* 参数：wait:是否等待启动完毕(Boolean)
* 返回ProcessStateStruct[]集合
*/
public static final String startAllProcesses="supervisor.startAllProcesses";
/**
* 关闭进程
* 参数1:group:name(String);
* 参数2:wait:是否等待状态返回(Boolean)
* 返回boolean
*/
public static final String stopProcess="supervisor.stopProcess";
/**
* 关闭所有进程
* 参数：wait:是否等待状态返回(Boolean)
* 返回ProcessStateStruct[]集合
*/
public static final String stopAllProcesses="supervisor.stopAllProcesses";
/**
* 重新加载配置文件
* 返回一个实体object
*/
public static final String reloadConfig="supervisor.reloadConfig";
/**
* 清理单个进程的日志，这里只是清理监控服务器对此进程记录的日志，并不是程序内部打印的日志
* 参数:group:name(String);
* 返回boolean
*/
public static final String clearProcessLogs="supervisor.clearProcessLogs";
}supervisor每个控制方法对应的参数不同，在方法常量里面有说明每个方法对应的参数项。
示例启动进程
/**
* 启动进程
* @param id
* @param group
* @param name
* @return
*/
public boolean startProcess(String id,String group,String name){
SupervisorConfig config=querySupervisorConfig(id);
if(StringUtils.isNotBlank(config.getUrl())&&StringUtils.isNotBlank(config.getUserName())&&StringUtils.isNotBlank(config.getPassword())) {
Vector<Object> params =new Vector<>();
params.addElement(String.format("%s:%s",group,name));
params.addElement(true);
Object result = SupervisorUtils.sendSupervisorCommand(config.getUrl(),config.getUserName(),config.getPassword(), SupervisorConstants.startProcess,params);
return Boolean.valueOf(result.toString());
}else{
return false;
}
}其中group与name，在“supervisor.getAllProcessInfo”返回的结果集里面是包含了这些信息,示例如下：
