是由于javaType和jdbcType的类型不匹配造成的.
通俗点讲，是你的SQL有问题。
出现异常的原代码
<select id="getMyNoticesNotPage" resultMap="BaseResultMap" parameterType="com.qskj.tzkw_oa_application.document.domain.DocuInfoVo2" > SELECT recv.ID, recv.PID, recv.SEND_USRID, recv.SEND_USRNAM, recv.RECV_USRID, recv.RECV_USRNAM, recv.READ_FLAG, recv.READ_TIME, recv.RECV_DEPTID FROM qs_tzkw_flw_docu_recv recv left join qs_tzkw_rms_user_info user on user.id = recv.RECV_USRID where user.id = #{userId} <if test="isLead !=null and isLead !=''"> and recv.RECV_DEPTID in ( #{depts} ) //如果depts是集合，不可以用${depts} </if> </select>修改后代码
<select id="getMyNoticesNotPage" resultMap="BaseResultMap" parameterType="com.qskj.tzkw_oa_application.document.domain.DocuInfoVo2" > SELECT recv.ID, recv.PID, recv.SEND_USRID, recv.SEND_USRNAM, recv.RECV_USRID, recv.RECV_USRNAM, recv.READ_FLAG, recv.READ_TIME, recv.RECV_DEPTID FROM qs_tzkw_flw_docu_recv recv left join qs_tzkw_rms_user_info user on user.id = recv.RECV_USRID where user.id = #{userId} <if test="isLead !=null and isLead !=''"> and recv.RECV_DEPTID in <foreach collection="depts" item="item" index="index" open="(" separator="," close=")"> #{item} </foreach> </if> </select>Mybatis查询实例，sql中的in在Mybatis中怎么写–以list为查询条件
//在service中把参数放到HashMap中 List<String> list = new ArrayList<String>(); list.add("x"); list.add("y"); list.add("z"); String s = "A" Date d = new Date(); HashMap<String,Object> param = new HashMap<String,Object>(); param.put("list",list); param.put("s",s); param.put("d",d); XXXDao.queryXXX(param); //在Mybatis的Mapper中是这么写： <select id = "queryXXX",resultType = "XXX", paramterType = "java.lang.HashMap"> select * from tab where zi_duan1 = #{s} and zi_duan2 = #{d} and zi_duan3 in <foreach item="item" index="index" collection="list" open="(" separator="," close=")"> #{item} </foreach> </select>
