實現Map傳參Mybatis

 

我這里直接使用注解方法:

DemoMapper接口:

    @Select("INSERT INTO demo01(id,`name`) VALUES(#{userId},#{userName})")  通過主鍵獲取對應值
    int addDemo(Map<Integer,String> maps);

 

測試類:

      Map<String,String> maps = new HashMap<String, String>();
        maps.put("userId","15");  ---- userId是主鍵
        maps.put("userName","冰冰");   -----userName是主鍵
//        maps.put(13,"李四");
        int i = sqlSession.insert("addDemo", maps);
//        int i = mapper.addDemo(demo);

        if(i>0){
            sqlSession.commit();
            System.out.println("添加成功");
        }else{
            System.out.println("添加失敗");

        }
//        List<Demo> list = mapper.getDemoListByLikeName("九");
//        for (Demo demo:list){
//            System.out.println(demo.getId()+" "+demo.getName());
//        }
        //6、釋放資源
        sqlSession.close();
        in.close();
