結論：

方案一：

<!--beans.xml中配置 掃描服務包 -->
<context:component-scan base-package="com.stono.service" />

package
 
 com.stono.service
@Service
@Lazy(false) // 註意這句
public class LoadDataService implements ServletContextAware {

    @Autowired
    TblMapper tblMapper;
    
    @Override
    public void setServletContext(ServletContext context) {

        }
}

方案二：

<!--在beans.xml 中進行配置-->
<bean id="loadDataService" class
 
="com.stono.service.LoadDataService"   lazy-init="false">
</bean>

package com.stono.serivce

@Service // @Component // 寫成@Component也可以
public class LoadDataService implements ServletContextAware {
    @Autowired
    TblMapper tblMapper;
        @Override
    public void setServletContext(ServletContext context) {
        }
}
