Question

大家好我在尝试将spring 3.0与hibernate 3.1集成时遇到问题，为什么我会遇到这种类型的错误。在＆＃34; HibernateDAO＆＃34;我刚刚使用的课程＃34; autowired＆＃34;技术为＆＃34; HibernateTemplate＆＃34;它的投掷错误...... 我随函附上＆＃34; applicationcontext＆＃34;和＆＃34; web.xml＆＃34;

 applicationContext:@

Answer 1

在您的情况下，您的applicationContext Dispatcher servlet具有* .do扩展名。

<servlet-mapping>
   <servlet-name>applicationContext</servlet-name>
       <url-pattern>*.do</url-pattern>
</servlet-mapping>

像这样更改你的控制器..你的RequestMapping应该有.do扩展名。请求来自带有.do扩展名的web.xml，请求应与您的控制器@RequestMapping注释匹配。所以添加这样，

@Controller
@RequestMapping("/")
public class AppController {

@RequestMapping(value="/home.do" method=RequestMethod.GET)
    public String SampleMethod(Model model){
