mybatis sql语句获取不到参数
需要一个userId 我在Dao层this.getSqlSession().selectOne("userManage.retrieveUserDetail", input);执行前
syso了 input 里面是有userId的 为什么执行的时候userId 是null??

Java code

<select id="retrieveUserDetail" parameterType="cdata" resultType="cdata">
          <![CDATA[
            SELECT u.user_id "userId",
                   u.user_name "userName",
                   u.password "password",
                   u.email "email",
                   u.phone_no "phoneNo",
                   u.fax_no "faxNo",
                   u.create_by "createBy",
                   u.create_date "createDate",
                   u.use_flag "useFlag",
                   u.address "address",
                   u.dept_id "deptId",
                   d.DEPT_NAME "deptname",
                   u.position "position",
                   u.mobile_no "mobileNo",
                   u.notes "notes",
                   u.sub_dept_id "subDeptId",
                    a.auth_code as "code"
              FROM T_user_m u ,t_auth_user a,t_dept_m d
             WHERE u.user_id = #{userId} and u.user_id=a.user_id and u.DEPT_ID=d.DEPT_ID
        ]]>
    </select>





------解决方案--------------------
WHERE u.user_id = #{userId}# and u.user_id=a.user_id and u.DEPT_ID=d.DEPT_ID
------解决方案--------------------
cdata是什么类型,定义了别名吗?
建议参数用Map代替
 parameterType="java.util.Map"
------解决方案--------------------
错了 

WHERE u.user_id = #userId# and u.user_id=a.user_id and u.DEPT_ID=d.DEPT_ID
------解决方案--------------------
一个参数就用parameterType=“java.lang.String”
