Spring3.0MVC和Hibernate基于annotation引文的整合
Spring3.0MVC和Hibernate基于annotation注解的整合
springmvc和hibernate的annotation集合:
首先web.xml
然后是applicationContext.xml
spring-serlvet.xml
entity:
userdaoimpl
userserviceimpl
usercontroller
有意见和建议请留下..
对的。和web.xml同级。
有时间我会加上结构图的。
首先检查你的jar包是否正确，
然后在看看你的配置
这个不能写错，
你的dao和service的注解要写对
最后你的controoler的Autowired是接口的不是实现
主要你的Autowired地方看看
springmvc和hibernate的annotation集合:
首先web.xml

请问一下你的spring-servlet是放在web-inf下面吗？

首先检查你的jar包是否正确，
然后在看看你的配置
<context:component-scan base-package="org.xlaohe1.web"/>
这个不能写错，
你的dao和service的注解要写对
最后你的controoler的Autowired是接口的不是实现
主要你的Autowired地方看看

可否把你的lib包用到的jar 贴出来啊？ 配置，代码真的一样。 估计和包有关系吧。
