Java JSP仅作为纯文本打印

我试图使用jstl打印参数，但即使使用EL表达式，它也会呈现为纯文本。我试图更改servlet和依赖项的版本，但仍然面临相同的问题。我正在使用tomcat8.0

spring servlet需要是默认的servlet。ie映射到/而不是/*。

只需从url模式中删除通配符（*）

<servlet>
<servlet-name>SpringMVC</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
   <servlet-name>SpringMVC</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>


SpringMVC
org.springframework.web.servlet.DispatcherServlet
1
SpringMVC
/

<servlet>
<servlet-name>SpringMVC</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
   <load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
   <servlet-name>SpringMVC</servlet-name>
   <url-pattern>/</url-pattern>
</servlet-mapping>
