调用mybatis generator已经生成好的dao来查询例子

package com.cib.xj.controller;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.cib.xj.dao.VAJMapper;
import com.cib.xj.pojo.VAJ;
import com.cib.xj.pojo.VAJExample;
import com.cib.xj.pojo.VAJExample.Criteria;

@Controller
public class AJController {
     @Resource
        private VAJMapper ajMapper;

      @RequestMapping( "/showAJ" )
        public String toIndex( String id, Model model )
        {
           VAJExample example=new VAJExample();
           Criteria criteria = example.createCriteria();
           criteria.andCardNoEqualTo(id);
           criteria.andCardNoIsNotNull();

          List<VAJ> result=ajMapper.selectByExample(example);
          model.addAttribute("result" ,result);
          return "AJ";
        }
}

先定义对应的dao类,用@Resource注释,mybatis配置好的话dao类就可以直接用了.

   @Resource
        private VAJMapper ajMapper;

用selectByExample查询数据库的例子

    VAJExample example=new VAJExample();
           Criteria criteria = example.createCriteria();
           criteria.andCardNoEqualTo(id);
           criteria.andCardNoIsNotNull();

          List<VAJ> result=ajMapper.selectByExample(example);
