CompanyServiceImpl 类
@Service("companyService")
@Transactional
public class CompanyServiceImpl extends CommonServiceImpl implements CompanyServiceI {

      private CompanyDao companyDao;

      @Arguments("company")
      public void insertCompany(CompanyEntity company) {
            // TODO Auto-generated method stub
            companyDao.insertCompany(company);
      }
}
CompanyDao 类
public interface CompanyDao extends MiniDaoSupportHiber<CompanyEntity>{

      @Arguments("company")
      public void insertCompany(CompanyEntity company);

问题找到了，原来是配置的问题
spring-minidao.xml文件里

      <bean id="proxyFactoryBean" class="org.springframework.aop.framework.ProxyFactoryBean">
            <property name="proxyInterfaces" >
                     <list>
                              <value>jeecg.photoManage.dao.CompanyDao</value>
                     </list>
            </property>
            <property name="interceptorNames">
                     <list>
                              <value>miniDaoHandler</value>
                     </list>
            </property>
      </bean>
中<value>jeecg.photoManage.dao.CompanyDao</value>这个值一定要指定到具体的DAO
