springmvc和hibernate的annotation集合:
首先web.xml 
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

  <context-param>

		<param-value>classpath*:applicationContext*.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>

	<servlet>
		<!-- this is 'spring' name for your spring-servlet.xml -->
		<servlet-name>spring</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>spring</servlet-name>
		<url-pattern>*.xl</url-pattern>
	</servlet-mapping>
  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>

能提供源码下载吗。楼主！！！

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
xlaohe1 写道
reggie_ysq 写道
一摸一样的代码和配置文件，但是总是有这个错，好汉给点建议啊

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，

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。

请问一下你的spring-servlet是放在web-inf下面吗？


对的。和web.xml同级。
有时间我会加上结构图的。
 <servlet>  
        <!-- this is 'spring' name for your spring-servlet.xml -->  
        <servlet-name>spring</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>
