java - MyBatis 多结果集与过程

Question

我尝试了以下映射:

<select id="getRequestDetail" statementType="CALLABLE" parameterType="test.domain.RequestDetailRequest" resultMap="ExternalManagersMap, SubjectServicesMap">
    {call pop.dbo.getRequestDetail ( #{uid, mode=IN, jdbcType=VARCHAR},
                            #{requestId, mode=IN, jdbcType=INTEGER},
                            #{resultStatus, mode=OUT, jdbcType=INTEGER},
                            #{resultMsg, mode=OUT, jdbcType=VARCHAR} )}
</select>


<resultMap type='test.domain.User' id="ExternalManagersMap">
        <result property="name" column="externalManager"/>
</resultMap>

<resultMap type='test.domain.Service' id="SubjectServicesMap">
        <result property="name" column="serviceName"/>
        <result property="id" column="serviceId"/>
</resultMap>

但是我有错误:

org.apache.ibatis.exceptions.TooManyResultsException: Expected one result (or null) to be returned by selectOne(), but found: 2

我的界面是: Map<String, Object> getRequestDetail(RequestDetailRequest detailRequest);

你能帮我如何用调用过程映射多个结果集吗？我的数据库是Sybase。

sqlSession.selectOne 表示您只期望从过程中返回一行。

相反，您应该使用 sqlSession.select
