我是新来的春天.我正在尝试使用spring mvc来构建一个小型Web.当我启动项目时,我得到:
org.apache.jasper.JasperException: Unable to compile class for JSP:

Http状态是500,但我的index.jsp只有
<html>
<body>
<h2>Hello World!</h2>
</body>
</html>
在web.xml中:
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/jsp/index.jsp</welcome-file>
</welcome-file-list>
action-servlet.xml:
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
<context:component-scan base-package="com.test.Controller"/>
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix"><value>/jsp/</value></property>
<property name="suffix"><value>.jsp</value></property>
</bean>
我把index.jsp放在src/main/webapp/jsp /文件夹下.任何人都可以给我一些关于这个问题和我的xml文件中的问题的提示.我是春天的新手,所以很多混乱.
非常感谢你!
它看起来有一些版本不匹配.确保servlet-api和jsp-api 不包含在您的WEB-INF/lib文件夹中
如果使用Maven,则必须将这些依赖项设置为<scope>provided</scope>以便它们不包含在工件中(target/foo.war)
如果使用eclipse,你应该安装另一个插件 - m2e-wtp,它负责<provided>范围依赖(m2e在与WTP同步时不会这样做)
