java - Spring 3.2 MVC - 无法将 URL 与 Controller 匹配

标签 java spring spring-mvc controller

我尝试使用 Spring 3.2 从头开始​​启动一个新应用程序，当我尝试访问我的 Controller 时出现 404 错误。这是我的配置:

WEB-INF
    web.xml
    web-context.xml

web.xml:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>

        </param-value>

    </listener>

    </servlet>
    <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/deblan/*</url-pattern>
    </servlet-mapping>

</web-app>

web-context.xml:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xmlns:context="http://www.springframework.org/schema/context"

       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">

    <context:component-scan base-package="com.deboralandini.web.controllers"/>
    <mvc:annotation-driven/>

    <beans>
        <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
            <property name="prefix" value="/WEB-INF/views/"/>
            <property name="suffix" value=".jsp"/>
        </bean>
    </beans>

</beans>

我的 Controller :

    package com.deboralandini.web.controllers;

    import ...;

    @Controller
    @RequestMapping("cuenta")
    public class CuentaController {

        @Autowired
        private CuentaService cuentaService;

        ...

        @RequestMapping(value = "/cCuenta")
        public String cCuenta(Model model){
            return "crearCuenta";
        }

        ...


    }

我的index.jsp:

<%@ taglib prefix="sf" uri="http://www.springframework.org/tags/form" %>
<html>
<body>
<h2>BlaBla</h2>
<br/>
<a href="cuenta/cCuenta">Crear Cuenta</a>
</body>
</html>

不幸的是，当我点击链接时，我得到:

Status HTTP 404 - /deblan/cuenta/cCuenta

浏览器尝试对 http://localhost:8080/deblan/cuenta/cCuenta 进行 GET，但我无法进入我的 Controller 。我调试了 Controller ，实际上没有进入那里，所以:我的新手错误是什么？

提前致谢 马科斯

编辑:这是我的输出:

最佳答案

如果 deblan 是上下文根，则不要将其放入 servlet 映射中。您已获得此网址:

http://localhost:8080/deblan/cuenta/cCuenta

如果您已使用 deblan 作为上下文根部署此应用程序，则:

http://localhost:8080/deblan

带您进入您的应用

/cuenta/cCuenta

现在映射到您的 Controller ，因此请尝试:

 <servlet-mapping>
        <servlet-name>appServlet</servlet-name>
        <url-pattern>/*</url-pattern>
 </servlet-mapping>

这意味着http://localhost:8080/deblan + 后面的内容。
