Question

我试图通过Spring-MVC显示一条简单的Hello消息。

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" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>SampleApplication</display-name>

      <welcome-file-list>
        <welcome-file>html/homepage.html</welcome-file>

    </welcome-file-list>

    <servlet>
        <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>

    <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>/WEB-INF/spring-servlet.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>

</web-app>

弹簧servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"  
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
        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.xsd 
        http://www.springframework.org/schema/mvc 
        http://www.springframework.org/schema/mvc/spring-mvc.xsd">


    <context:component-scan base-package="org.itc" /> 
    <mvc:resources mapping="/html/**" location="/html/" />
    <mvc:resources mapping="/js/**" location="/js/" />
    <mvc:annotation-driven />

</beans>

homepage.html

<!DOCTYPE html>
<html>
<head>
<meta charset="ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
   <h1>Hello world</h1>
</body>
</html>

这里homepage.html出现在WEB-INF / html文件夹中。我没有收到任何错误/异常。我使用的是Spring 4.0.6版本。对此有何帮助？

您应该在ViewResolver

中提及Spring-servlet.xml

<强>弹簧servlet.xml中

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:p="http://www.springframework.org/schema/p"  
    xmlns:context="http://www.springframework.org/schema/context" 
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="

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

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


    <context:component-scan base-package="org.itc" /> 
    <mvc:resources mapping="/html/**" location="/html/" />
    <mvc:resources mapping="/js/**" location="/js/" />
    <mvc:annotation-driven />
    //Add this..
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/html/" />  
        <property name="suffix" value=".html" />  
    </bean>

</beans>

<强>控制器

@RequestMapping(value = "/", method = RequestMethod.GET)
public String loadHtml(Map<String, Object> model, HttpServletRequest request) {
    return "homePage";
}

为什么简单的HTML页面没有通过Spring-MVC加载
