Question

servlet映射ViewRendererServlet指的是未定义web.xml的servlet

<?xml version="1.0" encoding="UTF-8"?>
<web-app id="WebApp_ID" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd">
<display-name>NWRedirectPortlet</display-name>
<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/context/applicationContext.xml</param-value>
</context-param>
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<servlet>
    <servlet-name>ViewRendererServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.ViewRendererServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>ViewRendererServlet</servlet-name>
    <url-pattern>/WEB-INF/servlet/view</url-pattern>
</servlet-mapping>

Answer 1

它抱怨，因为你在web.xml中没有其中一个：

<servlet>
    <servlet-name>ViewRendererServlet</servlet-name>
    <servlet-class>com.example.MyClass</servlet-class>
    ...
</servlet>

<强>更新

<servlet>和<servlet-mapping>是兄弟姐妹：

<servlet>
    <servlet-name>ViewRendererServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.ViewRendererServlet</servlet-class>
</servlet>

<servlet-mapping>
    <servlet-name>ViewRendererServlet</servlet-name>
    <url-pattern>/WEB-INF/servlet/view</url-pattern>
</servlet-mapping>

Answer 2

我只是修复了相同的错误。这不是语法错误，更多的是日食带来的问题。

只需打开servlet类（在您的情况下：org.springframework.web.servlet.ViewRendererServlet）一次，错误神奇地消失了。
