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
