mybatis根据Map来查询数据

	   select * from t_user t where
	   
	       
		         
	                ${key} = #{map[${key}]}
	             
	       
	       
	           1=2
	       
	   
	

DAO层：

List findByMap(@Param("map") Map map);

Test：

@Test
    public void testMap() {
	    Map map = new HashMap();
	    map.put("id", 3);
	    map.put("username", "李四");
        List list = dao.findByMap(map);
        print(list);
    }

SQL日志：
