来源：互联网发布：编程机器人2.0 攻略编辑：程序博客网时间：2024/04/30 11:08

环境：Eclipse Luna Service Release 2 (4.4.2)+Tomcat 7/8

描述：Eclipse可以正常启动Tomcat8 server来运行war包，但当通过网页访问其web时，出现如下crash信息，导致web无法访问。

但使用tomcat7可以正常访问web服务。

原因：

旧的servlet-api和tomcat8中冲突，使用javax.servlet-api。

解决方案：

将pom.xml文件中的依赖项servlet-api

<dependency><groupId>javax.servlet</groupId><artifactId>servlet-api</artifactId><version>2.5</version></dependency>

改成javax.servlet-api，如下

<dependency><groupId>javax.servlet</groupId><artifactId>javax.servlet-api</artifactId><version>3.1.0</version></dependency>

使用javax.servlet-api可以同时兼任tomcat7和tomcat8。
