}

（5）Control代码 以下代码我们看到

方法ResultMsg addNsrxx(@RequestBody NsrxxBo nsrxxbo)对应ajax的请求

通过@RequestBody NsrxxBo将提交的json转成对应的bo类，我们可以直接方便的使用bo进行操作

package com.zkxx.reportforms.demo.action;

import java.util.HashMap; import java.util.List; import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.ApplicationContext; import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestBody; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; import org.springframework.web.bind.annotation.ResponseBody; import com.zkxx.base.SpringContextUtil; import com.zkxx.base.ResultMsg;

import com.zkxx.reportforms.demo.bo.MxBo; import com.zkxx.reportforms.demo.bo.NsrxxBo;

import com.zkxx.reportforms.demo.service.DjnsrxxService;

@Controller

public class DjNsrxxAction {

private DjnsrxxService djnsrxxService;

public DjnsrxxService getDjnsrxxService() { }

@Autowired//自动注入service

public void setDjnsrxxService(DjnsrxxService djnsrxxService) { }

this.djnsrxxService=djnsrxxService;

return this.djnsrxxService;

}

@RequestMapping(\//对应ajax请求的url public @ResponseBody

ResultMsg addNsrxx(@RequestBody NsrxxBo nsrxxbo) throws Exception { }

@RequestMapping(\public @ResponseBody

ResultMsg queryNsrxxByNsrsbh(@RequestParam(\ System.out.println(nsrsbh); }

System.out.println(\

ResultMsg result=getDjnsrxxService().getInfoBysbh(nsrsbh); System.out.println(result.getRows().toString()); return result; ResultMsg ret; try{

ret=getDjnsrxxService().saveInfo(nsrxxbo);

}catch(Exception e){ }

return ret;

ret=new ResultMsg(); ret.setFhjg(\ret.setFhsm(\保存失败\e.printStackTrace();

（6）Service接口

package com.zkxx.reportforms.demo.service;

import com.zkxx.base.ResultMsg;

import com.zkxx.reportforms.demo.bo.NsrxxBo; public interface DjnsrxxService { }

ResultMsg saveInfo(NsrxxBo bo) throws Exception; ResultMsg getInfoBysbh(String sbh);

（7）Service接口实现

主要对数据库的操作不再累述

package com.zkxx.reportforms.demo.service.impl;

import java.util.List;

import org.springframework.stereotype.Service;

import org.springframework.transaction.annotation.Transactional; import com.zkxx.base.ResultMsg; import com.zkxx.db.DbExecuter;

import com.zkxx.reportforms.demo.bo.MxBo;

import com.zkxx.reportforms.demo.bo.NsrxxBo;

import com.zkxx.reportforms.demo.service.DjnsrxxService; @Service @Transactional

public class DjnsrxxServiceImpl implements DjnsrxxService{

public ResultMsg getInfoBysbh(String sbh) { }

@Transactional(rollbackFor = Exception.class)//事务回滚 public ResultMsg saveInfo(NsrxxBo bo) throws Exception{

// TODO Auto-generated method stub ResultMsg result=new ResultMsg();

int ret=DbExecuter.getInstance().addPojo2Db(bo,\if(ret<=0){ }

List list=bo.getMxlist(); if(list==null)return result; for(MxBo mx:list){

mx.setNsrsbh(bo.getNsrsbh()); mx.setNsrmc(bo.getNsrmc());

ret=DbExecuter.getInstance().addPojo2Db(mx,\if(ret<=0){ }

result.setFhjg(\result.setFhsm(\保存失败\return result; result.setFhjg(\result.setFhsm(\保存失败\return result;

// TODO Auto-generated method stub

String sql=\Object[] arr={sbh};

List list=DbExecuter.getInstance().query(sql, NsrxxBo.class, arr); for(NsrxxBo bo:list){ }

ResultMsg result=new ResultMsg(); result.setRows(list); return result;

String nsrsbh=bo.getNsrsbh(); Object[] arrmx={nsrsbh};

sql=\

List listmx=DbExecuter.getInstance().query(sql, MxBo.class, arr); bo.setMxlist(listmx);

}

}

}

return result;

至此一个简单的保存查询功能完成。
