问题描述
我使用Spring MVC.
当我单击jsp链接时，将加载其他jsp.
我有一些控制器.
我也使用
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
当我单击jsp链接时，我得到一个404
项目结构为
我的jsp是
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

@Resource(name = "preferencesService")
private PreferencesService preferencesService;
private int a = 0;
private static List<Preferencia> results = null;

}
调度员是

控制器位于eusuvey.controller软件包中
在调度程序中，我扫描软件包eusuvey
错误是
我必须定义jsp，控制器和调度程序来修复此404吗?
解决方案
使用@RequestMapping批注时，您宁愿使用org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping(弹簧2)或org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping(弹簧3)之类的东西. >
只需使用<mvc:annotation-driven />配置元素(参见M.Deinum注释)启用它即可.
I work with Spring MVC.
When I click in the jsp link other jsp is loaded.
I have some controllers.
Also I use
<bean class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping" />
When I click the jsp link I get a 404
Project structure is
My jsp is
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%>

WelcomeController.java is

@Resource(name = "preferencesService")
private PreferencesService preferencesService;
private int a = 0;
private static List<Preferencia> results = null;

Dispatcher is

</bean>
</beans>
Controller are in the packages eusuvey.controller
In the dispatcher I scan the package eusuvey
The error is
How do I have to define jsp, controller and dispatcher to fix this 404?
解决方案
When using @RequestMapping annotations, you'd rather need something like the org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping (spring 2) or org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping (spring 3).
Just enable it with an <mvc:annotation-driven /> config element (Cf. M.Deinum comment).
