配置执行器
启动相关xxl-job客户端服务后,会自动注册机器地址
简单任务
/**
* 简单任务
*
* @param params
* @return
*/
@XxlJob(value = "demoJob")
public ReturnT<String> demoJobHandler(String params) {
log.info("我是 jeecg-system 服务里的定时任务 demoJob,我执行了...............................");
return ReturnT.SUCCESS;
}
启动任务
分片任务
/**
* 2、分片广播任务
*/
@XxlJob("shardingJobHandler")
public ReturnT<String> shardingJobHandler(String param) throws Exception {
// 分片参数
ShardingUtil.ShardingVO shardingVO = ShardingUtil.getShardingVo();
log.info("分片参数:当前分片序号 = {}, 总分片数 = {}", shardingVO.getIndex(), shardingVO.getTotal());
// 业务逻辑
for (int i = 0; i < shardingVO.getTotal(); i++) {
if (i == shardingVO.getIndex()) {
log.info("第 {} 片, 命中分片开始处理", i);
} else {
log.info("第 {} 片, 忽略", i);
}
}
return ReturnT.SUCCESS;
}
分片任务需要多个xxl-job客户端服务,这样才能达到并行分片处理定时任务的优势。这里我们利用idea的相关设置去启动同一个demo客户端服务;但记得启动前修改下服务端口
运行定时任务
第一台机
第二台机
第三台机
第四台机
第五台机
命令任务
/**
* 3、命令行任务
*
* 输入参数:ipconfig /all
*/
@XxlJob("commandJobHandler")
public ReturnT<String> commandJobHandler(String param) throws Exception {
String command = param;
int exitValue = -1;
BufferedReader bufferedReader = null;
try {
// command process
Process process = Runtime.getRuntime().exec(command);
BufferedInputStream bufferedInputStream = new BufferedInputStream(process.getInputStream());
bufferedReader = new BufferedReader(new InputStreamReader(bufferedInputStream));
// command log
String line;
while ((line = bufferedReader.readLine()) != null) {
log.info(line);
}
// command exit
process.waitFor();
exitValue = process.exitValue();
} catch (Exception e) {
log.info(e.getMessage(),e);
} finally {
if (bufferedReader != null) {
bufferedReader.close();
}
}
if (exitValue == 0) {
return IJobHandler.SUCCESS;
} else {
return new ReturnT<String>(IJobHandler.FAIL.getCode(), "command exit value(" + exitValue + ") is failed");
}
}
跨平台Http任务
/**
* 4、跨平台Http任务
*
* 输入参数:
* url: https://www.baidu.com
* method: get
* data: content
*/
@XxlJob("httpJobHandler")
public ReturnT<String> httpJobHandler(String param) throws Exception {
String[] methodArray=new String[]{"GET","POST"};
int okState=200;
// param parse
if (param == null || param.trim().length() == 0) {
log.info("param[" + param + "] invalid.");
return ReturnT.FAIL;
}
String[] httpParams = param.split("\n");
String url = null;
String method = null;
String data = null;
for (String httpParam : httpParams) {
if (httpParam.startsWith("url:")) {
url = httpParam.substring(httpParam.indexOf("url:") + 4).trim();
}
if (httpParam.startsWith("method:")) {
method = httpParam.substring(httpParam.indexOf("method:") + 7).trim().toUpperCase();
}
if (httpParam.startsWith("data:")) {
data = httpParam.substring(httpParam.indexOf("data:") + 5).trim();
}
}
// param valid
if (url == null || url.trim().length() == 0) {
log.info("url[" + url + "] invalid.");
return ReturnT.FAIL;
}
if (method == null || !Arrays.asList(methodArray).contains(method)) {
log.info("method[" + method + "] invalid.");
return ReturnT.FAIL;
}
// request
HttpURLConnection connection = null;
BufferedReader bufferedReader = null;
try {
// connection
URL realUrl = new URL(url);
connection = (HttpURLConnection) realUrl.openConnection();
// connection setting
connection.setRequestMethod(method);
connection.setDoOutput(true);
connection.setDoInput(true);
connection.setUseCaches(false);
connection.setReadTimeout(5 * 1000);
connection.setConnectTimeout(3 * 1000);
connection.setRequestProperty("connection", "Keep-Alive");
connection.setRequestProperty("Content-Type", "application/json;charset=UTF-8");
connection.setRequestProperty("Accept-Charset", "application/json;charset=UTF-8");
// do connection
connection.connect();
// data
if (data != null && data.trim().length() > 0) {
DataOutputStream dataOutputStream = new DataOutputStream(connection.getOutputStream());
dataOutputStream.write(data.getBytes("UTF-8"));
dataOutputStream.flush();
dataOutputStream.close();
}
// valid StatusCode
int statusCode = connection.getResponseCode();
if (statusCode != okState) {
throw new RuntimeException("Http Request StatusCode(" + statusCode + ") Invalid.");
}
// result
bufferedReader = new BufferedReader(new InputStreamReader(connection.getInputStream(), "UTF-8"));
StringBuilder result = new StringBuilder();
String line;
while ((line = bufferedReader.readLine()) != null) {
result.append(line);
}
String responseMsg = result.toString();
log.info(responseMsg);
return ReturnT.SUCCESS;
} catch (Exception e) {
log.info(e.getMessage(),e);
return ReturnT.FAIL;
} finally {
try {
if (bufferedReader != null) {
bufferedReader.close();
}
if (connection != null) {
connection.disconnect();
}
} catch (Exception e2) {
log.info(e2.getMessage(),e2);
}
}
}
由于我这个环境是内网,没有外网,报如下错误,暂时无法验证,可自行参考流程验证
生命周期任务
/**
* 5、生命周期任务示例:任务初始化与销毁时,支持自定义相关逻辑;
*/
@XxlJob(value = "demoJobHandler2", init = "init", destroy = "destroy")
public ReturnT<String> demoJobHandler2(String param) throws Exception {
log.info("XXL-JOB, Hello World.");
return ReturnT.SUCCESS;
}
public void init() {
log.info("init");
}
public void destroy() {
log.info("destory");
}
