看看是不是hibernate配置文件的类BizClaimVoucherDetail的路径配置错误了

雪夜微舞 能具体说一下吗
3 年多之前 回复

检查你的jar包,可能存在多余的jar,或者有低版本的同名jar包要删除

po.BizClaimVoucherDetail类不存在,是不是项目没有编译成功呢?重新clean下项目试试。

没有看见你引入数据源呀,还要你的配置文件Hibernate.cfg.xml的H大写可以检查一下

SSH项目中,怎么实现不读取spring配置文件 ,自己手动new 一个DAO类

一个SSH项目需要和apache RPC整合,而在这个RPCService类中需要频繁用到一个已经用spring配置好的DAO类, 我目前是在构造中读取Spring配置文件, 客户端每调用一次这个RPCService类就会执行一次构造方法,这样频繁读取spring配置文件感觉系统会崩......... 有没有什么方法能够不读取spring配置文件手动new出这个DAO类对象呢? 希望高手给予分析和指教!~~

ssh配置文件位置的问题

<p>现在采用struts2、spring、hibernate做一个项目。为了使结构更清晰把spring和struts2的配置文件都放在了WEB-INF/config目录下。在配置struts2的时候就遇到了问题,因为默认struts2是用classpath下加载配置文件。现在用spring测试框架进行单元测试,又遇到了配置文件无法加载的问题,搜了半天都没找到合适的解决方案,请问使用ssh的朋友们是怎么做的?</p> <pre name="code" class="java">@ContextConfiguration(locations={"../WEB-INF/config/applicationContext.xml"}) public class TestSysUserService extends AbstractTransactionalJUnit4SpringContextTests { @Autowired private SysUserService userService; @Test public void testGetSysUserList(){ DataPage dataPage=userService.getUserList(1, 10); for(int i=0;i&lt;dataPage.getData().size();i++){ System.out.println("用户姓名:"+((SysUser)dataPage.getData().get(i)).getName()); } } public SysUserService getUserService() { return userService; } public void setUserService(SysUserService userService) { this.userService = userService; } }</pre>

各位大佬,maven项目中spring配置文件一直加载不到

启动tomcat,一直报错说找不到另一个模块中的一个spring配置文件。无论怎么 maven update都没用。必须要删除,重新从gitlab上拉下来才能行。然后过一段时间又不行了。又要重新拉。求各位大牛支招(其他同事基本上没问题,也有几个跟我一样的问题)

SSH框架与SpringMVC+hibernate各组件负责什么,体现在哪?

本人java小白,最近在一个比较老的项目代码中,想了解一个问题,就是SSH与SpringMVC中,各组件都负责什么,具体体现在哪,如何体现,就是一打眼就能看出来的,尤其是Hibernate这个框架,我感觉它的存在感很低不知道哪里用到它了,是实体关系映射用到了它么?还有Spring在SSH中就在配置文件中简单的解了下耦,也没有利用注解将请求直接请求到控制器上,仅仅就用了那一点?还有就是这两种框架,对于事物都是spring来负责?

ssh框架动态建立数据库访问连接

各位大神,想问一个问题:用ssh框架怎么实现动态的去连接数据库,然后还能用hibernate存取数据。完成 就是在ssh框架里,连接数据库正常不是去读取配置文件连相应的数据库吗,但是现在出现的需求就是你去存取数据之时首先(另一个模块的人写的接口可以根据数据id返回你这个数据所存的数据库服务器地址,库名以及用户密码等等信息),这时候需要把这个信息和当前项目连接的数据库地址比对,如果一样,就正常存取,不一样,就连上人家返回的服务器地址所在数据库去存取。 我的思路是什么呢,整合jdbc和hibernate。连接数据库走jdbc,操作数据库走hibernate。但是不知道行不行,也不知道怎么弄

在用SSH框架开发项目中的XML配置

对于我现在已经在项目开发中用到了SSH的框架,但是在项目开发过程中遇到的XML配置的问题,在XML配置文件中里面有太多的配置标签,有时会用到自己从来就没有见过的标签,又不知道它们该如何用,为什么要用?用了有啥好处?为了解决这个问题,我现在想请那位大神给我说一下,请把在SSH框架中以及SpringMVC的配置文件的总结的所有的属性以及属性值给我说一下。我好积累下来。以备以后工作中使用。谢谢!

SSH中Spring的作用是什么

Struts和Hibernate的作用很清楚,一个负责MVC,一个负责持久化。但是Spring的作用呢?Spring统管了Struts和Hibernate,通过IOC改变了类的实例化方式,仅仅是这样吗? 我感觉没有Spring也没有什么不好啊,就直接New吗,有什么问题呢?
