java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.pages.LandingPage_jsp
提问by abc32112
I'm getting two very odd errors when opening a project. If I open the landing page and keep refreshing it, the error messages alternate between the two below.
打开项目时，我遇到了两个非常奇怪的错误。如果我打开登录页面并不断刷新它，错误消息会在以下两个页面之间交替出现。
Either I get this:
要么我得到这个：
org.apache.jasper.JasperException: /WEB-INF/pages/LandingPage.jsp (line: 2, column: 0) The absolute uri: http://www.springframework.org/security/tags cannot be resolved in either web.xml or the jar files deployed with this application
Or this:
或这个：
HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.pages.LandingPage_jsp
What on earth is happening?
到底发生了什么？

Because:
因为：
Cause 1: Parsing JSP file error. For example: Error JSP page (due syntax error or missing dependencies):
原因 1：解析 JSP 文件错误。例如：错误 JSP 页面（由于语法错误或缺少依赖项）：
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<body>
<h1>Hello world!</h1>
<p>The time on server is ${serverTime}.</p>
</body>
</html>
Make it correct:
使其正确：
<%@page session="false" %>
<html>
<head>
<title>Home</title>
</head>
<body>
<h1>Hello world!</h1>
<p>The time on server is ${serverTime}.</p>
</body>
</html>
Cause 2: missing dependencies. Fix it by add these dependencies:
原因 2：缺少依赖项。通过添加这些依赖项来修复它：
<dependency>
<groupId>javax.servlet.jsp.jstl</groupId>
<artifactId>jstl-api</artifactId>
<version>1.2</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
<scope>provided</scope>
</dependency>
<dependency>
<groupId>javax.servlet.jsp</groupId>
<artifactId>jsp-api</artifactId>
<version>2.2</version>
<scope>provided</scope>
</dependency>
You must set scopelike the above.
你必须scope像上面那样设置。

In my case, AOP was reporting that I could speed up tomcat and webapp start time by adding jars to the catalina.properties section "tomcat.util.scan.StandardJarScanFilter.jarsToSkip", including jstl-1.2.jar.
就我而言，AOP 报告说我可以通过将 jar 添加到 catalina.properties 部分“tomcat.util.scan.StandardJarScanFilter.jarsToSkip”（包括 jstl-1.2.jar）来加快 tomcat 和 webapp 的启动时间。

I had this error:HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.views.index_jsp
我有这个错误：HTTP Status 500 - java.lang.ClassNotFoundException: org.apache.jsp.WEB_002dINF.views.index_jsp
In index.jsp i have some line:<%@include file="header.jsp"%>
But clean name of file was Header.jsp. Look at your LandingPage.jsp (line: 2, column: 0) closely. Good luck!
在 index.jsp 中，我有一些内容：<%@include file="header.jsp"%>
但是文件的干净名称是 Header.jsp。仔细查看您的 LandingPage.jsp（第 2 行，第 0 列）。祝你好运！

I also had the same issue once. It was resolved by changing the version of tomcat plugin from 2.0 to 2.2.
我也遇到过同样的问题。通过将 tomcat 插件的版本从 2.0 更改为 2.2 解决了这个问题。
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
</plugin>

In my case a simple application rebuild-redeploy helped me to solve the similar exception. It seems like some resources (jsp ?) were missing in the initial build.
就我而言，一个简单的应用程序重建重新部署帮助我解决了类似的异常。初始构建中似乎缺少一些资源（jsp？）。

In my case it was caused by tomcat putting compiled jsps into /tmp which then got cleared. This is reported issue: https://github.com/spring-projects/spring-boot/issues/5009
在我的情况下，它是由 tomcat 将编译后的 jsps 放入 /tmp 引起的，然后被清除。这是报告的问题：https: //github.com/spring-projects/spring-boot/issues/5009

This might also be caused by following hints that effectively disable JSP support in Tomcat 8+ to improve (startup) performance.
这也可能是由于遵循有效禁用 Tomcat 8+ 中的 JSP 支持以提高（启动）性能的提示。
Do notinclude JasperInitializerin the context's containerSciFilterproperty (in conf/context.xml).
不要不包括JasperInitializer在范围内的containerSciFilter属性（在conf/context.xml）。
