batch-file - MyBatis 批量更新异常

Question

我正在使用 mybatis更新 mysql数据库，但是当我运行我的测试程序时，我发现了一个 BadSqlGrammarException 我不知道如何解决它。谁能看看它并给我一些有用的建议？

以下是我的问题详细信息:

Mybatis SQL 文件:

<update id="updateTestcaseNodeBatch" parameterType="List">
  <foreach collection="list" item="nodeVO" separator=";">
    UPDATE testcase_node
     <set>
       name=#{nodeVO.name},
       version=#{nodeVO.version},
       description=#{nodeVO.description},
       last_modify_user=#{nodeVO.createUser},
       last_modify_time=#{nodeVO.createTime}
     </set>
     <where>
       object_id=#{nodeVO.objectId} AND root_id=#{nodeVO.rootId}
     </where>
  </foreach>
</update>

Java 方法块:

@Override
public int[] parseImportTestcaseData(List<TestcaseNodeVO> nodeList) {


            int[] result=new int[3];
            int ignoreNum=0;
            List<TestcaseNodeVO> addList=new ArrayList<TestcaseNodeVO>();
            List<TestcaseNodeVO> updateList=new ArrayList<TestcaseNodeVO>();

            TestcaseNodeModel tempNode=null;
            for(TestcaseNodeVO nodeVO:nodeList){
                tempNode=testcaseNodeDao.queryNodeByObjectId(nodeVO.getObjectId(),nodeVO.getRootId());

                if(tempNode==null){
                    addList.add(nodeVO);
                }else{
                    if(tempNode.getVersion()<nodeVO.getVersion()){
                        updateList.add(nodeVO);
                    }else{
                        ignoreNum++;
                    }
                }

                tempNode=null;
            }

            if(addList.size()>0){
                testcaseNodeDao.addTestcaseNodeBatch(addList);  
            }
            if(updateList.size()>0){
                testcaseNodeDao.updateTestcaseNodeBatch(updateList);
            }


            result[0]=addList.size();
            result[1]=updateList.size();
            result[2]=ignoreNum;

            return result;
}   

* 最后是我的异常堆栈跟踪:

通过sql异常堆栈跟踪，我发现这是由于我的语法错误，因此我尝试了我的Mybatis XML块如下(删除分隔符属性并在每个sql的末尾添加一个分号)，但仍然失败:

<update id="updateTestcaseNodeBatch" parameterType="List">
      <foreach collection="list" item="nodeVO">
        UPDATE testcase_node
         <set>
           name=#{nodeVO.name},
           version=#{nodeVO.version},
           description=#{nodeVO.description},
           last_modify_user=#{nodeVO.createUser},
           last_modify_time=#{nodeVO.createTime}
         </set>
         <where>
           object_id=#{nodeVO.objectId} AND root_id=#{nodeVO.rootId};
         </where>
      </foreach>
</update>

我已经尝试了很多方法来做到这一点，但仍然找不到解决方案，有人能帮我解决吗？提前致谢!

我认为问题是 mysql 默认不支持执行多条 sql，但在您的情况下，批量更新需要这样做。所以您必须添加
参数“ allowMultiQueries ”来启用它。
像下面这样:
jdbc:mysql://10.255.10.105:3306/PB_MANAGEMENT_PLATFORM?allowMultiQueries=true
