Controller控制器部分

//分页查询
@RequestMapping(value="/Search/{Searchname}/{Searchinstid}", method = RequestMethod.GET)   // get方式传递接收地址参数
public String Search(
@RequestParam(required = false, defaultValue = "1") int page,
@RequestParam(required = false, defaultValue = "20") int rows,
@PathVariable("Searchname") String shopname,   //获取传递的参数值
@PathVariable("Searchinstid") Integer institutionid,
HttpServletRequest request, Model model){
try {
shopname = URLDecoder.decode(shopname, "UTF-8");              //解码过程  避免中文乱码
} catch (Exception ex) {
}
if (shopname.equals("all")) {                 // 为空用all做中间转换
shopname = "";
}
PageHelper.startPage(page, rows);
List<BtyShop> list = btyshopService.SearchSearch(shopname,institutionid);       //调用Service传参查询
request.setAttribute("pageInfo", new PageInfo<BtyShop>(list));
List<Inst> insts = instService.getAll();
request.setAttribute("insts", insts);
request.setAttribute("shoplist", list);
// 回写查询数据
model.addAttribute("Searchshopname", shopname);
model.addAttribute("Searchinstitutionid", institutionid);

}

Service部分  

public List<BtyShop> SearchSearch(String shopname, Integer institutionid) {            //传递参数查询
Map<String,Object> param = new HashMap();　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　　
param.put("shopname", shopname);
param.put("institutionid", institutionid);          //往集合中添加键值对
List<BtyShop> BtyShop=btyShopMapper.SearchSearch(param);　　　　　　//调用Mappper的方法查询，由于Mapper只能传一个参数，将多个参数转换为Map集合
return BtyShop;
}

Mapper.java部分

List<BtyShop> SearchSearch(Map<String, Object> param);  //只有一个方法跳转执行sql语句

-------------------------------------------------------------------------------------------------------------------------------------------------------

Mapper.xml部分              //配置sql语句

<select id="SearchSearch" resultMap="BaseResultMap" parameterType="java.util.Map" >  //类型为map
