我使用Oracle DB和Apache mybatis在Weblogic 12c下运行Java应用程序。
对于单个插入，我使用此映射器：
(x,y)从java我正在做以下事情：
<resultMap id="DataQualityCRUDPlainResultMap" type="de.vkd.niswrapper.model.persistence.DataQualityCRUD">
<id column="ID" property="id" jdbcType="DECIMAL" />
<result column="REGION" property="region" jdbcType="DECIMAL" />
<result column="ONB_NUM" property="onbNum" jdbcType="DECIMAL" />
<result column="ASB_NUM" property="asbNum" jdbcType="DECIMAL" />
<result column="FIBERNODES_TOTAL" property="fiberNodesTotal" jdbcType="DECIMAL" />
<result column="FIBERNODES_COUNT" property="fiberNodesCount" jdbcType="DECIMAL" />
<result column="FIBERROUTE_TOTAL_COUNT" property="fiberrouteTotalCount" jdbcType="DECIMAL" />
<result column="FIBERROUTE_LONGITUDE" property="fiberrouteLongitude" jdbcType="DECIMAL" />
<result column="FIBERROUTE_TOTAL_COUNT_USED" property="fiberrouteTotalCountUsed" jdbcType="DECIMAL" />
<result column="FIBERROUTE_LONGITUDE_USED" property="fiberrouteLongitudeUsed" jdbcType="DECIMAL" />
<result column="DT_CREATION" property="dtCreation" jdbcType="TIMESTAMP" />
</resultMap>
<sql id="cols">
${alias}ID,
${alias}REGION,
${alias}ONB_NUM,
${alias}ASB_NUM,
${alias}FIBERNODES_COUNT,
${alias}FIBERNODES_TOTAL,
${alias}FIBERROUTE_TOTAL_COUNT,
${alias}FIBERROUTE_LONGITUDE,
${alias}FIBERROUTE_TOTAL_COUNT_USED,
${alias}FIBERROUTE_LONGITUDE_USED,
${alias}DT_CREATION
</sql>
<insert id="insert" parameterType="de.vkd.niswrapper.model.persistence.DataQualityCRUD">
INSERT INTO NW_NIS_DATA_QUALITY (
<include refid="cols">
<property name="alias" value="" />
</include>
)
VALUES (
#{id},
#{region},
#{onbNum},
#{asbNum},
#{fiberNodesTotal},
#{fiberNodesCount},
#{fiberrouteTotalCount},
#{fiberrouteLongitude},
#{fiberrouteTotalCountUsed},
#{fiberrouteLongitudeUsed},
#{dtCreation, jdbcType=TIMESTAMP}
)
</insert>
这是有效的，但不是最佳的。
我想消除循环中的for (final DataQuality aDQ : aDQList) {
DataQualityCRUD myDDQCrud = new DataQualityCRUD();
fillFields(aRegion, now, aDQ, myDDQCrud); dataQualityCRUDMapper.insert(myDDQCrud);
}
并执行值列表的insert。
为实现这一目标，我做了以下工作：
insert我已将Map<String, Object> map = new HashMap<String, Object>();
for (final DataQuality aDQ : aDQList) {
DataQualityCRUD myDDQCrud = new DataQualityCRUD();
fillFields(aRegion, now, aDQ, myDDQCrud);
resultList.add(myDDQCrud);
}
map.put("list", resultList);
dataQualityCRUDMapper.insertAll(map);
Mapper规范添加到insertAll规范中，如下所示：
<insert id="insertAll" parameterType="java.util.Map">
INSERT INTO NW_NIS_DATA_QUALITY (
<include refid="cols">
<property name="alias" value="" />
</include>
) VALUES
<foreach collection="list" item ="element" open = "(" separator="),(" close=")">
#{element.id},
#{element.region},
#{element.onbNum},
#{element.asbNum},
#{element.fiberNodesTotal},
#{element.fiberNodesCount},
#{element.fiberrouteTotalCount},
#{element.fiberrouteLongitude},
#{element.fiberrouteTotalCountUsed},
#{element.fiberrouteLongitudeUsed},
#{element.dtCreation, jdbcType=TIMESTAMP}
</foreach>
</insert>
不幸的是，这会产生如下异常（我不理解）：
### Error updating database. Cause: java.sql.SQLSyntaxErrorException:
ORA-00933: SQL command not properly ended ### The error may involve
de.vkd.niswrapper.adapter.gis.mapping.DataQualityCRUDMapper.insertAll-

任何提示？
