我遵循了开发spring web mvc应用程序的教程。我也使用maven来更轻松地解决我的家属,但似乎没有用。当我尝试运行项目时,它不会转到我的index.jsp,如果我尝试运行每个页面,它也会返回404。 这是我的控制器:
package com.springmvc.tutorial.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class HelloController {
@RequestMapping("/")
public ModelAndView helloWorld(){
String message ="Hello world! Spring !";
return new ModelAndView("hello","message",message);
}
}
这是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" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">
<display-name>SpringMVC9Tutorial</display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
<servlet>
<description></description>
<display-name>spring</display-name>
<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>/</url-pattern>
</servlet-mapping>
</web-app>
这是spring-servlet.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"

xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd">
<context:component-scan
base-package="com.springmvc.tutorial.controller">
</context:component-scan>
<bean id="viewResolver"
class="org.springframework.web.servlet.view.UrlBasedViewResolver">
<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<mvc:default-servlet-handler />
</beans>
我的jsps有以下结构:
WEB-INF/index.jsp
WEB-INF/web.xml
WEB-INF/spring-servlet.xml
WEB-INF/jsp/hello.jsp
我看到这可能是一个重复的问题,但我找不到让我满意的答案。我没有任何错误或例外,可能只是一条警告信息:
[SetPropertiesRule]{Server/Service/Engine/Host/Context} Setting property 'source' to 'org.eclipse.jst.jee.server:SpringMVC9Tutorial' did not find a matching property.
这是教程;我没有完全遵循它: http://viralpatel.net/blogs/spring-3-mvc-create-hello-world-application-spring-3-mvc/
答案 0 :(得分:2)
我认为您的servlet上下文未正确初始化。请尝试在web.xml中指定servlet
<servlet-name>spring</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring-servlet.xml</param-value>
</init-param>
编辑:您的servelt上下文命名与servletname匹配,因此您不需要明确提及该文件。如果您有特定名称,您可以像上面一样指定。
<property name="prefix" value="/WEB-INF/jsp/"></property>
WEB-INF/index.jsp
您错过了WEB-INF中jsp的文件夹,正如您在servelt上下文中提到的那样。但是你的JSP不在jsp文件夹中。
告诉spring在spring-servlet.xml中通过这样的注释加载控制器
<mvc:annotation-driven/>
