我的Spring MVC配置有什么问题？

Question

我正在尝试设置并学习如何使用Spring MVC开发Web应用程序。我一直在尝试遵循许多教程，但我的应用程序似乎不想工作。

环境：日食，m2e-wtp，春天，整个舍邦

上下文根是 BidApp。

我有一个控制器：

@Controller
public class AuctionController {    
    @RequestMapping("/hello")
    public ModelAndView helloWorld() {
        String message = "Hello World, Spring 3.0!";
        return new ModelAndView("hello", "message", message);
    }
}

我的网络.xml在 WEB-INF 中：

<!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>
    <display-name>BidApp</display-name>
    <servlet>
        <servlet-name>dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet
        </servlet-class>
        <load-on-startup>1</load-on-startup>
         <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>/WEB-INF/spring-servlet.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>*.*</url-pattern>
    </servlet-mapping>
</web-app>

还有我的弹簧.xml也在 WEB-INF 中

<?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:mvc="http://www.springframework.org/schema/mvc"
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="
        http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
        http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    <!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
    <!-- Scans within the base package of the application for @Components to configure as beans -->
    <!-- @Controller, @Service, @Configuration, etc. -->
    <context:component-scan base-package="com.bidapp.controllers" />
    <!-- Enables the Spring MVC @Controller programming model -->
    <mvc:annotation-driven />
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/" />
        <property name="suffix" value=".jsp" />
    </bean>
</beans>

我的我启动应用程序并导航到http://localhost:8080/BidApp/hello，它给了我一个 404。我的 xml 文件是否位于错误的位置或缺少某些配置参数？有没有一个好地方我可以查看用于配置 spring 应用程序的所有可用参数。除非我读错了，否则 spring 框架参考没有帮助。

Answer 1

你必须像这样使用 url 模式

<url-pattern>/</url-pattern>

当您将<mvc:annotation-driven />添加到配置中时，它将替换默认的处理程序映射和处理程序适配器集，这些默认值是处理旧式控制器的默认值。

我认为您应该了解组件扫描和注释配置之间的区别。如果使用扫描，则无需使用配置。<上下文：注释配置>与<上下文：组件扫描>之间的区别

请使用旧代码执行并删除<mvc:annotation-driven />

（一般来说）/即使没有 mvcdefault servlethandler 也能工作

Answer 2

调度程序具有无效的映射。仅接受 1 个通配符。

因此，将调度程序匹配 url 更改为类似 /*

所以/*.do或/*.htm *.html但不/*.jsp，因为tomcat已经映射了.jsps

如果你想要一些 REST 网址，我可以建议使用 UrlRewriteFilter 吗？它使用起来非常简单，可以像使用 apache 重写过滤器

Answer 3

将

url-pattern 更改为 <url-pattern>/</url-pattern> 是不够的。在我的 spring-servlet.xml 文件中，我缺少一些元素：

<!-- DispatcherServlet Context: defines this servlet's request-processing infrastructure -->
<!-- This tag allows for mapping the DispatcherServlet to "/" (all extensions etc)-->
<mvc:default-servlet-handler/>

<!-- Enables many annotations and searches for @Controller annotated methods etc.. -->
<context:annotation-config />

添加这些后，将找到相应的控制器（基于注释），并从 / 开始在正确的 URI 上执行该控制器。
