查询List<Map>类型数据

只要设定resultType而不设定resultMap就可以了。

Java接口：

List<Map<String, String>> getMtypeList();

XML：

<select id="getMtypeList" parameterType="java.util.Map" resultType="java.util.HashMap">
    select code,`name` from jk_control_measure rs
    where rs.TYPE_ID != 1
        <if test="qKeyWord != null">
            and rs.stock_code = #{qKeyWord}
        </if>
        <if test="rsTitle != null">
            and rs.title like #{rsTitle}
        </if>
        order by rs.crt_time desc limit #{pageIndex}, #{pageSize}
</select>

输出结果：

[
    {"NAME":"地面冲洗","name":"地面冲洗","code":"one","CODE":"one"},
    {"NAME":"边界围挡","name":"边界围挡","code":"two","CODE":"two"},
    {"NAME":"垃圾覆盖","name":"垃圾覆盖","code":"three","CODE":"three"},
    {"NAME":"裸地覆盖","name":"裸地覆盖","code":"four","CODE":"four"},
    {"NAME":"洒水降尘","name":"洒水降尘","code":"five","CODE":"five"}
]
