定義名稱 引用定義的線程池
@Autowired
@Qualifier("rptGenExecutor")
private ThreadPoolTaskExecutor rptExec;
使用：
Runnable action = new RptGenTask(conditcionParamVO, reportType);
rptExec.execute(action);
RptGenTask 實現runable接口
添加帶參數的構造函數來傳遞需要的值
重寫 run方法，
定義靜態上下文：
@Component
public class RptEntrance implements ApplicationContextAware {
private static ApplicationContext applicationContext;
@Override
public void setApplicationContext(ApplicationContext applicationContext) throws BeansException {
this.applicationContext = applicationContext;
ServiceBuilder.initAppCtx(applicationContext);
}
public static ApplicationContext getContext() {
return applicationContext;
}
}
package com.nttdata.elearning.report.service;
import org.springframework.context.ApplicationContext;
public class ServiceBuilder {
private static ApplicationContext ctx;
static void initAppCtx(ApplicationContext appCtxIn){
ctx = appCtxIn;
}
public static <T> Object getService(String serviceName, Class<T> serviceClazz){
return ctx.getBean(serviceName, serviceClazz);
}
}
class RptGenTask implements Runnable {
private RptRequest req = null;
private String rptTemplNo = null;
RptGenTask(RptRequest rptReq, String rptType){
this.req = rptReq;
this.rptTemplNo = rptType;
}
@Override
public void run() {
}
｝
註入bean
ApplicationContext ctx=RptEntrance.getContext();
//TODO 從當前的Spring ApplicationContext中，獲取命名的Service/Component;
this.reportService = (ReportService) ctx.getBean("reportService");
