Dao界面 AllCustomerHistDao.java

    public void addCustomer(AllCustomerHist allcustomerhist);

}

DaoImpl课程 AllCustomerHistDaoImpl.java

//      return session.getCurrentSession().createCriteria(AllCustomerHist.class).list();

这是我的数据服务 AllCustomerHistService.java

    public void addCustomer(AllCustomerHist allcustomerhist);

服务类impl AllCustomerHistServiceImpl.java 

import java.math.BigDecimal;

    @Transactional
    public List getAllCustomer() {
        // TODO Auto-generated method stub
        return allcustomerhistdao.getAllCustomer();
    }

}

问题是，当我部署并点击http://localhost:7001/adpwebapi/customer/list时，它会抛出：

  

休息开始   ＆lt; [ServletContext @ 17211 44​​524 [app：adp.service.layer   module：adp.service.layer.war path：null spec-version：   3.1]，request：weblogic.servlet.internal.ServletRequestImpl@43d1999b [GET /adp.service.layer/adpwebapi/customer/list HTTP / 1.1 User-Agent：   Mozilla / 5.0（Windows NT 6.2; WOW64; rv：54.0）Gecko / 20100101 Firefox /   54.0接受：text / html，application / xhtml + xml，application / xml; q = 0.9， / ; q = 0.8   Accept-Language：id，en-US; q = 0.7，en; q = 0.3 Accept-Encoding：gzip，   deflate Connection：keep-alive Upgrade-Insecure-Requests：1

     

]] ServletException的根本原因。显示java.lang.NullPointerException           在com.id.astra.MyResource.getAllCustomer（MyResource.java:56）           at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method）           at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl。   Java的：62）           at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAcces   sorImpl.java:43）           at java.lang.reflect.Method.invoke（Method.java:498）           截断。查看日志文件以获取完整的堆栈跟踪   ＆GT;

我不知道line发生了什么：return AllCustomerHistService.getAllCustomer（）;抛出空指针异常

请给我建议，因为我是hibernate和spring framework的新手

此致
