在eclipse / tomcat8

Question

我正在使用Eclipse和Tomcat 8.我使用Spring创建了一个动态Web项目。这是我的 web.xml 文件：

<?xml version="1.0" encoding="ISO-8859-1"?>
<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_2_5.xsd"
id="WebApp_ID" version="2.5">

<!-- When using Spring JDBC, use the following: -->
<context-param>

</context-param>

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/business-config.xml</param-value>
</context-param>

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

<!-- - Servlet that dispatches request to registered handlers (Controller 
    implementations). -->
<servlet>
    <servlet-name>oh</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring/mvc-core-config.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

<servlet-mapping>
    <servlet-name>oh</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

<!-- used to provide the ability to enter Chinese characters inside the 
    Owner Form -->

    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

        <param-value>UTF-8</param-value>
    </init-param>
    <init-param>
        <param-name>forceEncoding</param-name>
        <param-value>true</param-value>
    </init-param>
</filter>

<filter-mapping>
    <filter-name>encodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>


<!-- used so we can use forms of method type 'PUT' and 'DELETE' see here: 
    http://static.springsource.org/spring/docs/current/spring-framework-reference/html/view.html#rest-method-conversion -->
<filter>
    <filter-name>httpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>

<filter-mapping>
    <filter-name>httpMethodFilter</filter-name>
    <servlet-name>oh</servlet-name>
</filter-mapping>

business-config.xml 文件包含有关存储库和服务bean的数据源定义和组件扫描的信息。

我的 mvc-core-config.xml 文件包含以下行：

<!-- uses WebJars so Javascript and CSS libs can be declared as Maven dependencies 
    (Bootstrap, jQuery...) -->
<mvc:resources mapping="/webjars/**"
    location="classpath:/META-INF/resources/webjars/" />

<mvc:view-controller path="/" view-name="welcome" />

<!-- serve static resources (*.html, ...) from src/main/webapp/ Required 
    when both servlet-mapping is '/' and static resources need to be served -->
<mvc:default-servlet-handler />


<bean
    class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver">
    <!-- view name resolved using bean of type InternalResourceViewResolver 
        (declared in mvc-view-config.xml) -->
    <property name="defaultErrorView" value="exception" />
    <!-- results into 'WEB-INF/jsp/exception.jsp' -->
    <property name="warnLogCategory" value="warn" />
    <!-- needed otherwise exceptions won't be logged anywhere -->
</bean>

并且 mvc-view.config.xml 文件包含：

<mvc:view-resolvers>
    <mvc:content-negotiation use-not-acceptable="true">
        <mvc:default-views>
            <bean class="org.springframework.web.servlet.view.JstlView">
                <property name="url" value="" />
            </bean>
        </mvc:default-views>
    </mvc:content-negotiation>

    <mvc:jsp prefix="/WEB-INF/jsp/" suffix=".jsp" />
</mvc:view-resolvers>

因此，在运行tomcat服务器后，在 localhost：8080 / oh 打开我的应用程序，我得到一个404页面，但我期待着我的welcome.jsp页面。

在localhost：8080打开tomcat页面并列出已安装的应用程序，哦应用程序已正确部署。

我做错了什么？

如果我使用tomcat7 maven插件：

      <plugin>
            <groupId>org.apache.tomcat.maven</groupId>
            <artifactId>tomcat7-maven-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <server>tomcat-development-server</server>
                <port>9966</port>
                <path>/oh</path>
            </configuration>
        </plugin>

并在运行：mvn tomcat7:run后，在网址上打开网络应用程序： http://localhost:9966/oh/

欢迎页面正确显示。
