遇到俩问题：一个是mybatis生疏  在EmpMapper.xml中定义resultMap

 <resultMap id="EmpWithDept" type="com.lwp.bean.Emp">
        <id column="emp_id" property="empId"></id>
        <result column="emp_name" property="empName"></result>
        <result column="gender" property="gender"></result>
        <result column="email" property="email"></result>
        <result column="d_id" property="did"></result>
        <association property="dept" javaType="com.lwp.bean.Dept">
            <id column="dept_id" property="deptId"></id>
            <result column="dept_name" property="deptName"></result>
        </association>
    </resultMap>

其中column是表的字段   property是实体类 的字段  我给记反了

第二个问题   查出集合放入前端index.html 用thymeleay接受发现

An error happened during template parsing (template: "class path resource [templates/list.html]

经检查发现modelandview传来的是个字符串而不是集合

原：===》mv.addObject("pageInfo","pageInfo");

检查===》mv.addObject("pageInfo",pageInfo);
ok
