SpringMVC与Mybatis集合实现调用存储过程、事务控制实例

在SSM框架中经常会用到调用数据库中的存储过程、以及事务控制，下面以保存某单据为例，介绍一下：

1、Oracle中存储过程代码如下(主要逻辑将单据编码自动加1，并将该单据编码返回)：

CREATE OR REPLACE PROCEDURE "UPDATE_DJBHZT" (p_GSID in varchar2, p_TBLNAME in varchar2,
                  NewRecNo out Number) as
begin
  update BHDJ set BHDJ02 = BHDJ02+1 where GSXX01 = p_GSID and BHDJ01 = p_TBLNAME;
  if sql%rowcount = 0 then
    insert into BHDJ (GSXX01, BHDJ01,BHDJ02) values(p_GSID, p_TBLNAME,1);
  end if;
  select BHDJ02 into NewRecNo from BHDJ where GSXX01 = p_GSID and BHDJ01 = p_TBLNAME;
end; 

2、Mybatis中代码如下：

<select id="update_djbhzt" parameterType="java.util.Map" statementType="CALLABLE">
<![CDATA[
  {call UPDATE_DJBHZT(#{p_GSID,mode=IN,jdbcType=VARCHAR},#{p_TBLNAME,mode=IN,jdbcType=VARCHAR},#{NewRecNo,mode=OUT,jdbcType=BIGINT})}
]]>
</select>

3、Dao层代码如下：

package com.pcmall.dao.sale.stock; 

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

import com.github.miemiedev.mybatis.paginator.domain.PageBounds;
import com.pcmall.dao.common.BaseMapper;
import com.pcmall.domain.sale.stock.Zcd; 

public interface ZcdMapper extends BaseMapper<Zcd> { 

  void update_djbhzt(Map<String,Object> map);  

}

4、Service层代码如下：
接口：

package com.pcmall.service.sale.stock; 

import java.util.List; 

import com.github.miemiedev.mybatis.paginator.domain.PageBounds;
import com.pcmall.domain.sale.order.HssnCmmx;
import com.pcmall.domain.sale.stock.Zcd;
import com.pcmall.domain.sale.stock.Zcditem;
import com.pcmall.domain.sale.user.User;
import com.pcmall.domain.vo.ResponseVO;
import com.pcmall.service.common.IBaseService; 

public interface IZcdService extends IBaseService<Zcd> { 

  Long getZcdNo(String gsxx01, String tablename); 

  ResponseVO saveZcd(Zcd zcd, User user) throws Exception; 

}

实现类：

package com.pcmall.service.sale.stock.impl; 

import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map; 

import javax.annotation.Resource; 

import org.apache.axis.holders.SchemaHolder;
import org.apache.commons.collections.CollectionUtils;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional; 

import com.github.miemiedev.mybatis.paginator.domain.PageBounds;
import com.google.common.collect.Collections2;
import com.pcmall.common.utils.DateUtils;
import com.pcmall.dao.sale.stock.ZcdMapper;
import com.pcmall.dao.sale.stock.ZcditemMapper;
import com.pcmall.domain.sale.order.HssnCmmx;
import com.pcmall.domain.sale.promotion.HsCxlx;
import com.pcmall.domain.sale.stock.Zcd;
import com.pcmall.domain.sale.stock.Zcditem;
import com.pcmall.domain.sale.stock.bo.CkspBO;
import com.pcmall.domain.sale.user.User;
import com.pcmall.domain.vo.ResponseVO;
import com.pcmall.service.common.AbstractServiceImpl;
import com.pcmall.service.sale.order.IOrderService;
import com.pcmall.service.sale.stock.IStockService;
import com.pcmall.service.sale.stock.IZcdService; 

@Service
public class ZcdServiceImpl extends AbstractServiceImpl<Zcd> implements IZcdService { 

  @Resource
  private ZcdMapper zcdMapper; 

  @Resource
  private ZcditemMapper zcditemMapper; 

  @Resource
  private IStockService stockServiceImpl; 

  @Transactional(rollbackFor = Exception.class)
  @Override
  public ResponseVO saveZcd(Zcd zcd, User user) throws Exception {
    ResponseVO responseVO = new ResponseVO();
    Long zcd01 = getZcdNo(zcd.getGsxx01(), "ZCD");
    zcd.setZcd01(zcd01);
    zcd.setZcd05(user.getRyxx().getRyxx02());
    zcd.setZcd06(new Date()); 

    Date nowTime = new Date();
    SimpleDateFormat sdf = new SimpleDateFormat("hhmmssms");
    zcd.setTime01(sdf.format(nowTime)); 

    for(Zcditem zcditem : zcd.getZcditem()){
      zcditem.setZcd01(zcd01);
      zcditemMapper.insertSelective(zcditem);
    } 

    zcdMapper.insertSelective(zcd); 

    responseVO.setData(zcd);
    return responseVO;
  } 

  @Override
  public Long getZcdNo(String gsxx01, String tablename) {
    Map<String, Object> map = new HashMap<String, Object>();
    map.put("p_GSID", gsxx01);
    map.put("p_TBLNAME", tablename); 

    zcdMapper.update_djbhzt(map);
    Long NewRecNo = (Long) map.get("NewRecNo");
    return NewRecNo;
  }
}

5、Control层代码如下：

package com.pcmall.controller.stock.zcd; 

import java.util.List; 

import javax.annotation.Resource;
import javax.servlet.http.HttpServletRequest; 

import org.apache.commons.collections.CollectionUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
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.github.miemiedev.mybatis.paginator.domain.PageBounds;
import com.pcmall.common.base.BaseController;
import com.pcmall.domain.sale.stock.Zcd;
import com.pcmall.domain.sale.stock.Zcditem;
import com.pcmall.domain.sale.stock.bo.CkspDetailBO;
import com.pcmall.domain.sale.stock.bo.ZcdBO;
import com.pcmall.domain.sale.system.Gzzqx;
import com.pcmall.domain.sale.system.GzzqxKey;
import com.pcmall.domain.sale.system.Ryxx;
import com.pcmall.domain.sale.user.Czy;
import com.pcmall.domain.sale.user.User;
import com.pcmall.domain.vo.ResponseVO;
import com.pcmall.service.sale.stock.IStockService;
import com.pcmall.service.sale.stock.IZcdService;
import com.pcmall.service.sale.system.IGzzqxService; 

@Controller
@RequestMapping("/stock/zcd")
public class ZCDController extends BaseController { 

  private static Logger logger=LoggerFactory.getLogger(ZCDController.class); 

  @Resource
  private IZcdService zcdServiceImpl; 

  @Resource
  private IStockService stockServiceImpl; 

  @Resource
  private IGzzqxService gzzqxServiceImpl; 

  @RequestMapping("/saveZcd")
  @ResponseBody
  public ResponseVO saveZcd(HttpServletRequest request, @RequestBody Zcd zcd){
    ResponseVO responseVO = new ResponseVO();
    try{
      responseVO = zcdServiceImpl.saveZcd(zcd, getLoginUser());
      responseVO.setSuccess(true);
    }
    catch (Exception e) {
      logger.error("",e);
      responseVO.setSuccess(false);
      responseVO.setErrorMsg(!"".equals(e.getMessage()) ? e
          .getMessage() : "后台异常");
    }
    return responseVO;
  } 

}

6、前端js层代码如下：

function save() {
    $("#save").addClass("disabled"); 

    if ($("#selSHCK").val() == "") {
      layer.msg('请填写收货仓库', {
        icon : 5
      });
      $("#save").removeClass("disabled");
      return;
    } 

    if($("#selSHCK").val() == $("#selFHCK").val()){
      layer.msg('发货仓库与收货仓库不能一样', {
        icon : 5
      });
      $("#save").removeClass("disabled");
      return;
    } 

    var param = {};
    param.bm01 = $("#selBm").attr("valuea");
    param.zcd02 = $("#selFHCK").attr("valuea");
    param.zcd03 = $("#selSHCK").attr("valuea");
    param.zcd04 = $("#zcd04").val();
    param.gsxx01 = $("#gsxx01").val(); 

    var zcditemAry = [];
    var flag = 0;
    $("#tbody1").find("tr").each(function() {
      var zcditem = {};
      var arrtd = $(this).children(); 

      zcditem.spxx01 = $.trim(arrtd.eq(0).text());
      zcditem.wldw01 = $.trim(arrtd.eq(6).text());
      zcditem.zcdi01 = $.trim(arrtd.eq(7).text()); 

      if($.trim(arrtd.eq(2).children(".zcdi03").val()) == ""){
        /* layer.msg('请输入转仓数量', {
          icon : 5
        });
        $("#save").removeClass("disabled"); */ 

        flag = 1;
        return;
      } 

      zcditem.zcdi02 = $.trim(arrtd.eq(2).children(".zcdi03").val());
      zcditem.zcdi03 = $.trim(arrtd.eq(2).children(".zcdi03").val());
      zcditem.zcdi05 = $.trim(arrtd.eq(8).text());
      zcditem.zcdi06 = $.trim(arrtd.eq(4).children(".zcdi06").val());
      zcditem.gsxx01 = $("#gsxx01").val();
      zcditem.zcdi07 = $.trim(arrtd.eq(9).text());
      zcditemAry.push(zcditem);
    })
    param.zcditem = zcditemAry; 

    if(flag == 1){
      layer.msg('请输入转仓数量', {
        icon : 5
      });
      $("#save").removeClass("disabled");
      return;
    } 

    if (zcditemAry.length == 0) {
      layer.msg('请输入转仓商品信息', {
        icon : 5
      });
      $("#save").removeClass("disabled");
      return;
    }
  /* else{
      for(var i=0;i<zcditemAry;i++){
        if(zcditemAry[i].zcdi03 == ""){
          layer.msg('请输入转仓数量', {
            icon : 5
          });
          $("#save").removeClass("disabled");
          return;
        }
      }
    } */ 

    $.ajax({
      url : "${ctx }/stock/zcd/saveZcd",
      data : $.json.decode(param),
      contentType : "application/json",
      type : "POST",
      dataType : "json",
      success : function(data) {
        if (data.success) {
          $("#zcd01").val(data.data.zcd01);
          $("#zcd05").val(data.data.zcd05);
          $("#zcd06").val(data.data.zcd06);
          layer.msg('制定转仓单成功', {
            icon : 6
          });
        } else {
          layer.msg('制定转仓单失败' + data.errorMsg, {
            icon : 5
          });
          $("#save").removeClass("disabled");
        }
      }
    });
  }
