Mybatis读取oracle的CLOB类型字段

 <resultMap type="java.util.HashMap" id="partyVoiceMap">

        <result property="content" column="CONTENT" javaType="java.lang.String" jdbcType="CLOB" />
        <result property="contenttxt" column="CONTENTTXT" javaType="java.lang.String" jdbcType="CLOB" />
    </resultMap> 

在返回值那边使用

 <select id="getPartyNewsDetail" resultType="java.util.HashMap" resultMap="partyVoiceMap">
        select t.*, d.name dictname  from PB_PARTY_NEWS t left join PB_PARTY_NEWS_TYPE d  on d.id = t.TYPE  where t.id = #{newsId}
    </select>
