我刚才又检查了一边发现是因为 <select id="findByPage" resultMap="java.util.Map 这里错了" parameterType="java.util.Map"> SELECT*FROM user limit #{start},#{size} </select> 正确的是 <select id="findByPage" resultMap="queryUser" parameterType="java.util.Map"> SELECT*FROM user limit #{start},#{size} </select> 这里的resultMap="queryUser" 应该要和<resultMap type="User" id="querUser">里的id对应

被自己蠢哭哈哈哈
