我有很多这样定义的 DAO：
IxxxDAO
我正在使用MyBatis，这是我的配置：
@Configuration
@MapperScan(basePackages = {
"com.dounets.app.adm.**.dao",
"com.dounets.app.pi.bil.**.dao",
"com.dounets.app.pi.common.**.dao",
"com.dounets.app.pi.dd.**.dao",
"com.dounets.app.pi.dm.**.dao",
"com.dounets.app.pi.dmv2.**.dao",
"com.dounets.app.pi.pim.**.dao",
"com.dounets.app.pi.report.**.dao",
"com.dounets.app.pi.tat.**.dao",
"com.dounets.app.pi.ui.**.dao",
"com.dounets.app.process.dao",
})
public class MyBatisConfiguration {
@Bean
public SqlSessionFactory sqlSessionFactory(DataSource dataSource, ApplicationContext applicationContext) throws Exception {
SqlSessionFactoryBean sessionFactoryBean = new SqlSessionFactoryBean();
sessionFactoryBean.setDataSource(dataSource);
sessionFactoryBean.setMapperLocations(applicationContext.getResources("classpath:mapper/*.xml"));
return sessionFactoryBean.getObject();
}
}
如果我注释掉一些包，它工作得很好。但是如果我扫描所有包，它会抛出异常：
Unsatisfied dependency expressed through bean property 'sqlSessionFactory'
完整错误：
Unsatisfied dependency expressed through bean property 'sqlSessionFactory': :
Error creating bean with name 'IAdmCmtUsrLikeDAO' defined in file [IAdmCmtUsrLikeDAO.class]:
我试图扫描每个包裹，所有包裹都很好。
让我们看看我的示例 IxxxDAO：
public interface IAdmCmtUsrLikeDAO extends IApplicationDAO {
int delete(AdmCmtUsrLikeVOKey data) throws SQLException;
int insert(AdmCmtUsrLikeVO data) throws SQLException;
List<AdmCmtUsrLikeVO> select() throws SQLException;
AdmCmtUsrLikeVO select(AdmCmtUsrLikeVOKey data) throws SQLException;
int update(AdmCmtUsrLikeVO data) throws SQLException;
int update(HashMap<String, Object> data) throws SQLException;
}
