网上有很多方式获取ApplicationContext，但是实现都很麻烦。我在找了很久找到这种方式，so easy！（web中获取）

import java.util.List;import javax.servlet.ServletContext;import org.activiti.engine.delegate.DelegateTask;import org.activiti.engine.delegate.TaskListener;import org.springframework.web.context.ContextLoader;import org.springframework.web.context.WebApplicationContext;import org.springframework.web.context.support.WebApplicationContextUtils;import com.lifeng.jk.domain.SysUser;import com.lifeng.jk.service.SysUserService;/** * @author lifeng * */public class ZjlListener implements TaskListener{@Overridepublic void notify(DelegateTask delegateTask) {<strong><span style="color:#ff0000;">WebApplicationContext webApplicationContext = ContextLoader.getCurrentWebApplicationContext();//重点</span></strong>    ServletContext servletContext = webApplicationContext.getServletContext();  //SysUserService sysUserService = (SysUserService) webApplicationContext.getBean("sysUserServiceImpl");List<SysUser> sysUsers = sysUserService.findByJobsCode("zjl");for (SysUser sysUser : sysUsers) {system.out.println("");}}}
