1.代码

@Autowired    private	 SqlSessionFactoryBean  sqlSessionFactory  ;	@RequestMapping(value = "f3")	public String f3( @RequestBody Map
    
       map,HttpServletRequest request, HttpServletResponse response) throws Exception {		SqlSessionFactory object = sqlSessionFactory.getObject();		SqlSession session = null;		try {			session = object.openSession();			Object selectOne = session.selectOne("test.get2", map);			 MappedStatement mappedStatement = session.getConfiguration().getMappedStatement("test.get2");			String jsonString = JsonMapper.toJsonString(selectOne);			System.out.println(11);		} finally {			session.close();		}		return "f1";	}
    

    	
     		SELECT 			 *		FROM test_data a		WHERE a.id = #{id}				
     		SELECT 			*		FROM test_data a		WHERE a.id = #{id}	
    

2.前台

$.ajax({			        url :'${ctx}/test/testData/f3?book=java',			        type: 'post',			        dataType : "json",			        contentType:'application/json;charset=UTF-8',//关键是要加上这行			        data : JSON.stringify( {id:'22',remarks:'aaa'}),			        async : false, // 同步请求			        success : function(data) {			             debugger ;			        }			    });

 

3,转成json   ,在数据库就转成 json

        <select id="get2" resultType="map">

        SELECT 

            id,user_id, date_format(create_date,'%Y-%m-%d') as cdate

        FROM test_data a

        WHERE a.id = #{id}

    </select>

4, 数据对比

a.id AS "id",		a.user_id AS "user.id",		a.office_id AS "office.id",		a.area_id AS "area.id",		a.name AS "name",		a.sex AS "sex",		a.in_date AS "inDate",		a.create_by AS "createBy.id",	     date_format(create_date,'%Y-%m-%d')  AS "createDate",		a.update_by AS "updateBy.id",		date_format(update_date,'%Y-%m-%d') AS "updateDate",		a.remarks AS "remarks",		testint,		a.del_flag AS "delFlag"

上面可以重新 封装成map
