Question

我开发了一个示例maven项目（参考link）。最后，事实并非如此按预期运行。

以下是代码：
的的web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="2.4"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">

<display-name>Counter Web Application</display-name>

<servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>cleanTempDirectory</param-name>
        <param-value>false</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>mvc-dispatcher</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

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

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

<welcome-file-list>
    <welcome-file>welcome.jsp</welcome-file>
</welcome-file-list>

MVC-调度-servlet.xml中

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

<context:component-scan base-package="com.mkyong.controller" />

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

的welcome.jsp

<h1>Welcome..!!!</h1>
<a href="/SampleProj/home.html">click</a>
<%-- <%request.getRequestDispatcher("/home.html").forward(request,  response);%> --%>

针对home.jsp

<html>
<body>
<h1>Maven + Spring MVC Web Project Example</h1>
</body>

BaseController.java

@Controller
public class BaseController {

private static final String VIEW_INDEX = "home";

@RequestMapping(value = "home.html")
public String welcome(ModelMap model) {

    model.addAttribute("message", "Welcome");

    // Spring uses InternalResourceViewResolver and return back index.jsp
    return VIEW_INDEX;

}
}

的pom.xml

我尝试了所有可能的情况但根本没用。但是来自另一个eclipse版本和另一个工作区（相同的tomcat版本）的其他项目工作正常。我尝试了与maven相同的项目（从构建路径添加jar），它的工作。对于maven来说，它没有按预期发生。我想，pom文件被中断了流程。是否需要更改eclipse设置。（Show View（Problems）中没有错误）。建议我..

Answer 1

我认为部署程序集中缺少maven依赖项。因此，请将maven依赖项添加到部署程序集中。

项目 - ＆gt;属性 - ＆gt;部署程序集 - ＆gt;添加 - > Java 构建路径条目 - ＆gt; Maven依赖项。

完成上述过程后，重新启动tomcat服务器。

Tomcat服务器已启动但未从控制器
