Failure to launch Tomcat from IntelliJ IDEA
提问by Doug
I am a complete beginner at writing Java web apps, but I'm getting into Spring MVC.
我是编写 Java Web 应用程序的完整初学者，但我正在学习 Spring MVC。
I have created a default spring app and am attempting to launch it using TomCat 8.0
我创建了一个默认的 spring 应用程序，并尝试使用 TomCat 8.0 启动它
I am met with the following error:
我遇到了以下错误：
SEVERE: ContainerBase.addChild: start:
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]
....
Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/catalina/loader/WebappClassLoader) previously initiated loading for a different type with name "javax/servlet/ServletContext"
SEVERE: ContainerBase.addChild: start:
org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]
....
Caused by: java.lang.LinkageError: loader constraint violation: loader (instance of org/apache/catalina/loader/WebappClassLoader) previously initiated loading for a different type with name "javax/servlet/ServletContext"
I know this might sound simple but I have no idea where to start. I assume from the message that either my Maven, project or build settings are incorrect as the wrong Type of servlet is being instantiated?
我知道这听起来可能很简单，但我不知道从哪里开始。我从消息中假设我的 Maven、项目或构建设置不正确，因为正在实例化错误的 servlet 类型？
Any help to get setup would be greatly appreciated.
任何获得设置的帮助将不胜感激。

As mentioned in some of the comments, this was caused by a duplication of referenced dependencies.
正如一些评论中提到的，这是由引用依赖项的重复引起的。
more specifically this was a reference to javax.servlet
更具体地说，这是对 javax.servlet
To fix this, I opened my project's pom.xmlfile and removed the following:
为了解决这个问题，我打开了我的项目pom.xml文件并删除了以下内容：
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
<dependency>
<groupId>javax.servlet</groupId>
<artifactId>servlet-api</artifactId>
<version>2.5</version>
</dependency>
This fixed the problem. Weirdly enough, as I don't know enough about the Java build system or dependency inherritence in Java, I couldn't find another reference to javax.servletin my pom.xml file and therefore I don't know where the second reference was coming from?
这解决了问题。奇怪的是，由于我对 Java 构建系统或 Java 中的依赖继承不够了解，我javax.servlet在 pom.xml 文件中找不到另一个引用，因此我不知道第二个引用来自哪里？

i face this problem due to url pattern problem.it's only my experience.it was like this url-pattern="a/b" after solved like this url-pattern="/a/b"
由于 url 模式问题，我面临这个问题。这只是我的经验。像这样 url-pattern="a/b" 解决后就像这样 url-pattern="/a/b"
