以下是代码：
package cn.hr.controller; import java.io.PrintWriter; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpSession; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Controller; import org.springframework.transaction.PlatformTransactionManager; import org.springframework.transaction.TransactionDefinition; import org.springframework.transaction.TransactionStatus; import org.springframework.transaction.support.DefaultTransactionDefinition; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import cn.hr.base.action.BaseAction; import cn.hr.service.IAnnualbonuService; @Controller @RequestMapping(value="/demoTest") public class DemoTestController extends BaseAction<Object>{ @Autowired private IAnnualbonuService annualbonuService; @Autowired private PlatformTransactionManager transactionManager; /** * * @param payNamelist * @param request * @param response * @param session */ @RequestMapping(value = "/deletePayNamelist",method = RequestMethod.POST) public void deletePayNamelist(HttpServletRequest request, HttpServletResponse response,HttpSession session) { PrintWriter out = null; TransactionStatus status = this.transaction(); try { //=====================业务逻辑处理地方================================ out=response.getWriter(); out.write("0"); out.flush(); transactionManager.commit(status); } catch (Exception e) { transactionManager.rollback(status); out.write(""); out.flush(); logger.error(e); }finally{ out.flush(); out.close(); } } private TransactionStatus transaction(){ DefaultTransactionDefinition defaultTransactionDefinition = new DefaultTransactionDefinition(); defaultTransactionDefinition.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED); TransactionStatus status = transactionManager.getTransaction(defaultTransactionDefinition); return status; } }主要是transaction这个方法，意思是：new 一个新的事务，再设置自己所需要的事务隔离级别，最后通过注入的transactionManager得到该事务即可。百分百生效！
