Question

我的目录结构是

enter image description here

我在Apache Ivy中使用Spring MVC。我的web.xml是

<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>Spring Web MVC Application</display-name>


  <servlet>
    <servlet-name>mvc-dispatcher</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <load-on-startup>1</load-on-startup>
  </servlet>

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

</web-app>

我的调度程序servlet弹簧配置是

<beans xmlns="http://www.springframework.org/schema/beans"
    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-2.5.xsd">

    <bean id="viewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix">
            <value>/WebContent/pages/</value>
        </property>
        <property name="suffix">
            <value>.jsp</value>
        </property>

    </bean>

    <bean id="urlMapping"
        class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
        <property name="mappings">
            <props>
                <prop key="/welcome.htm">testController</prop>
                <prop key="/login.htm">loginController</prop>
            </props>
        </property>
    </bean>

    <bean id="testController" class="TestController">
    </bean>

    <bean id="loginController" class="LoginController">
    </bean>

</beans>

我正在测试localhost：8080 / TestWebProject / login.htm。它正确地命中了Login控制器。然而，我得到了以下错误

如您所见，该路径与我的目录结构相匹配。不知道我错过了什么。有什么建议吗？

将路径更改为/TestWebProject/pages/Login.jsp，但它显示了我

java.lang.LinkageError: loader constraint violation:
when resolving interface method "javax.servlet.jsp.JspApplicationContext.getExpressionFactory()Ljavax/el/ExpressionFactory;" the class loader (instance of org/apache/jasper/servlet/JasperLoader) of the current class, and the class loader (instance of org/apache/catalina/loader/StandardClassLoader) for resolved class, javax/servlet/jsp/JspApplicationContext, have different Class objects for the type javax/el/ExpressionFactory used in the signature

这主要是因为ivy下载的依赖项与Tomcat运行时提供的依赖项冲突。

首先转到Project - > Properties - >target Runtime并选择Apache Tomcat

这解决了这个问题，因为Ivy下载了传递依赖，并且它在运行时发生冲突。

所以我必须提供禁用传递依赖项解析的选项。我的常春藤终于有依赖了

<dependency org="org.springframework" name="spring-context" rev="4.0.4.RELEASE" transitive="false"/>
<dependency org="org.springframework" name="spring-beans" rev="4.0.4.RELEASE" transitive="false"/>
<dependency org="org.springframework" name="spring-core" rev="4.0.4.RELEASE" transitive="false"/>
<dependency org="org.springframework" name="spring-web" rev="4.0.4.RELEASE" transitive="false"/>
<dependency org="org.springframework" name="spring-expression" rev="4.0.4.RELEASE" transitive="false"/>

这修复了它，是的，因为评论建议/TestWebProject/pages/Login.jsp有效，而不是/TestWebProject/WebContent/pages/Login.jsp。

尽管Tomcat存在，但它无法找到所请求的资源
