mybatis 异常处理：Invalid bound statement (not found)

Posted 2020-10-18 有梦就能实现

mybatis 的使用过程中提示错误： 
org.apache.ibatis.binding.BindingException: Invalid bound statement (not found): com.msunsoft.mapper.HisLisReportMapper.getMaxMtcData

含义：HisLisReportMapper的getMtcData方法没有找到或者没有绑定

背景： 
1.HisLisReportSyncWorker 控制类中

String hospitalCode = ConfigRead.getValue("config.properties",
                    "HOSPITAL_CODE");
            List<Integer> updateIdList = new ArrayList<>();
            HisLisReportService hisLisReportService = (HisLisReportService) DataVisitorHolder
                    .getVisitorMap().get("hisLisReportService");
            HashMap<Object, Object> maxHisLisReportMap = hisLisReportService
                    .getMaxMtcData(hospitalCode);
            HashMap<Object, Object> map = hisLisReportService
                    .getMaxChangeVersion(hospitalCode);

HisLisReportServiceImpl

@Override
    @DataSource(name="blSql35")
    public HashMap<Object, Object> getMaxChangeVersion(String hospitalCode)
            throws Exception {
        // TODO Auto-generated method stub
        return hisLisReportMapper.getMaxChangeVersion(hospitalCode);
    }

 

HisLisReportMapper 代码

@Override
    public HashMap<Object, Object> getMaxChangeVersion(String hospitalCode)
            throws Exception ;

HisLisReportService 代码

@Override
    public HashMap<Object, Object> getMaxChangeVersion(String hospitalCode)
            throws Exception ;

Mybatis.xml文件

 <select id="getMaxChangeVersion" parameterType="java.lang.String" resultType="java.util.HashMap">
        select
        max(sys_change_version) as MAXVERSION ,max(etl_id) as MAXID from
        ETL.DBO.ETL_CHARGE_RECORD where hospital_code=#{hospitalCode} and etl_table=‘lismain.lisdata.report_main‘
    </select>

      <select id="getMaxMtcData" parameterType="java.lang.String" resultType="java.util.HashMap">
        select max(his_lis_report_id) as MAXID from his_lis_report where hospital_code=#{hospital_code}
     </select>

错误处理流程： 
我这里使用的SSM，spingMvc ,mybatis ,maven来构建项目，项目中使用了HisLisReportSyncWorker的控制类，HisLisReportServiceImpl代码实现，HisLisReportService接口类，HisLisReportMapper 的mapper类以及HisLisReportMapper.xml配置文件

1.检查实现类中方法是否存在

2。检查Service类的这个方法是否存在

3.检查Mapper类的这个方法

4.对应的mybatis 的配置文件是否存在，里面数据是否配置正确

5.检查Mapper类是否被加载了

这个错误主要是因为在config的配置文件中没有加载这个xml文件
