xxl-job与dubbo集成
https://github.com/xuxueli/xxl-job 下载，以2.0.2版本为例，无quartz版本
* 拷入xxl-job-admin ，xxl-job-core两个工程;
* 重命名工程，示例：xxl-job-admin改为dubbo-nacos-job-admin, xxl-job-core改为dubbo-nacos-job-common;
* 修改dubbo-nacos-job-common pom.xml，添加所需要的jar包，及指定xxl-job-rcp jar版本;
* 修改dubbo-nacos-job-admin pom.xml，添加所需要的jar包;
* 修改xxl-job表结构及初始化示例表数据
修改xxl_job_info表：
添加字段：
`executor_dubbo_method` varchar(20) DEFAULT NULL COMMENT 'dubbo服务调用方法名',
`executor_dubbo_version` varchar(8) DEFAULT NULL COMMENT 'dubbo服务版本号',
* 整改dubbo-nacos-job-common工程；
com.xxl.job.core.glue.GlueTypeEnum.java
添加枚举：
DUBBO("DUBBO", false, null, null),
com.xxl.job.core.executor.XxlJobExecutor.java
添加方法，在initAdminBizList方法前面：
public static IJobHandler loadDubboJobHandler(String address, TriggerParam triggerParam){
String cacheKey = triggerParam.getExecutorHandler() + "." + triggerParam.getDubboMethod() + "." + triggerParam.getDubboVersion();
if(jobHandlerRepository.containsKey(cacheKey)){
return jobHandlerRepository.get(cacheKey);
}
IJobHandler jobHandler = new DubboJobHandler(address , triggerParam);
jobHandlerRepository.put(cacheKey, jobHandler);
return jobHandler;
}
com.xxl.job.core.biz.model.TriggerParam.java
添加属性：
private String executorDubboMethod;
private String executorDubboVersion;
com.xxl.job.core.handler.impl包下添加类
新建类：com.xxl.job.core.handler.impl.DubboJobHandler.java
com.xxl.job.core.biz.impl.ExecutorBizImpl.java
添加属性：
/* dubbo nacos address , example=nacos://127.0.0.1:8848 */
private String address = "";
添加两个构架方法：
public ExecutorBizImpl() {
}
public ExecutorBizImpl(String address) {
this.address = address;
}
添加逻辑，com.xxl.job.core.biz.impl.ExecutorBizImpl#run方法里面，添加Dubbo的执行路由：
if (GlueTypeEnum.DUBBO == glueTypeEnum) {
jobHandler = XxlJobExecutor.loadDubboJobHandler(address, triggerParam);
if (logger.isDebugEnabled()) {
logger.debug("# jobHandler.hashCode()={}", jobHandler.hashCode());
}
} else if (GlueTypeEnum.BEAN == glueTypeEnum) {
com.xxl.job.core.log.XxlJobFileAppender.java
修改日志输出保存路径：
private static String logBasePath = "/Users/vincent/logs/jobhandler";
* 整改dubbo-nacos-job-admin工程 ；
com.xxl.job.admin.core.model.XxlJobInfo.java
添加属性：
private String executorDubboMethod; // 执行器，dubbo服务调用方法名
private String executorDubboVersion; // 执行器，dubbo服务版本号
src/main/resources/mybatis-mapper/XxlJobInfoMapper.xml
映射相关字段：
executor_dubbo_method —> executorDubboMethod
executor_dubbo_version —> executorDubboVersion
com.xxl.job.admin.core.conf.XxlJobScheduler.java
添加方法：
/**
* 创建dubbo执行器
* @param address
* @return ExecutorBiz
* @throws Exception
*/
public static ExecutorBiz getDubboEecutorBiz(String address) throws Exception {
// valid
if (address == null || address.trim().length() == 0) {
return null;
}
// load-cache
address = address.trim();
// String key = "zk.address." + address;
String key = "nacos.address." + address;
ExecutorBiz executorBiz = executorBizRepository.get(key);
if (executorBiz != null) {
return executorBiz;
}
executorBiz = new ExecutorBizImpl(address);
if (logger.isDebugEnabled()) {
logger.debug("# key={}, address={}", key, address);
}
executorBizRepository.put(key, executorBiz);
return executorBiz;
}
com.xxl.job.admin.core.trigger.XxlJobTrigger.java
修改方法逻辑，com.xxl.job.admin.core.trigger.XxlJobTrigger#processTrigger方法
添加executetorDubboMethod,executorDubboVersion传值映射
triggerParam.setExecutorDubboMethod(jobInfo.getExecutorDubboMethod());
triggerParam.setExecutorDubboVersion(jobInfo.getExecutorDubboVersion());
修改方法逻辑，com.xxl.job.admin.core.trigger.XxlJobTrigger#runExecutor方法 ，添加dubbo路由判断
GlueTypeEnum glueTypeEnum = GlueTypeEnum.match(triggerParam.getGlueType());
try {
ExecutorBiz executorBiz = null;
if (GlueTypeEnum.DUBBO == glueTypeEnum) {
executorBiz = XxlJobScheduler.getDubboEecutorBiz(address);
} else {
executorBiz = XxlJobScheduler.getExecutorBiz(address);
}
runResult = executorBiz.run(triggerParam);
} catch (Exception e) {
logger.error(">>>>>>>>>>> xxl-job trigger error, please check if the executor[{}] is running.", address, e);
runResult = new ReturnT
}
com.xxl.job.admin.core.thread.JobRegistryMonitorHelper.java
添加update xxl_job_group表的判断逻辑，大概是在78行左右
//group.setAddressList(addressListStr);
if (StringUtils.isNotBlank(addressListStr)) {
group.setAddressList(addressListStr);
}
com.xxl.job.admin.XxlJobAdminApplication.java
添加注解：
@EnableDubbo
dubbo-nacos-xxl-job-admin/src/main/resources/application.properties
添加与修改属性：
### spring main
spring.main.allow-bean-definition-overriding=true
spring.main.application.name=dubbo-nacos-job

修改方法逻辑，添加对dubbo支持，大概425行，改为如下：
// glueType change
$(".glueType").change(function(){
// executorHandler
var $executorHandler = $(this).parents("form").find("input[name='executorHandler']");
var $dubboDiv = $(this).parents("form").find("div[name='dubboDiv']");
var glueType = $(this).val();
if ('BEAN' != glueType && 'DUBBO' != glueType) {
$executorHandler.val("");
$executorHandler.attr("readonly","readonly");
$dubboDiv.hide();
} else {
$executorHandler.removeAttr("readonly");
if('BEAN' == glueType){
$dubboDiv.hide();
}else{
$dubboDiv.show();
}
}
});
修改代码添加，添加对dubbo支持，大概481行，改为如下：
$("#updateModal .form input[name='executorDubboMethod']").val( row.executorDubboMethod );
$("#updateModal .form input[name='executorDubboVersion']").val(row.executorDubboVersion);
src/main/resources/templates/jobinfo/jobinfo.index.ftl
添加dubbo支持，新增代码块修改：
添加dubbo支持，编码方法代码块：
com.xxl.job.admin.core.thread.JobRegistryMonitorHelper.java
添加判断逻辑：
//group.setAddressList(addressListStr);
if (StringUtils.isNotBlank(addressListStr)) {
group.setAddressList(addressListStr);
}
com.xxl.job.admin.service.impl.XxlJobServiceImpl.java
添加字段映射关系，com.xxl.job.admin.service.impl.XxlJobServiceImpl#update
exists_jobInfo.setExecutorDubboMethod(jobInfo.getExecutorDubboMethod());
exists_jobInfo.setExecutorDubboVersion(jobInfo.getExecutorDubboVersion());
