简而言之:没有配置Web服务器。
在出现此错误的项目上单击鼠标右键-->Build Path-->Configure Build Path
到了添加Server Library步骤时,里面是空选项,没有Tomcat 7.0选择,怎么办?
1、选择 eclipse 的WIndows菜单》Preferences 预设
2、在左侧列表中找到 Server 项,展开,选中:Runtime Environments,右侧点击添加按钮
3、这里要根据你使用的 Tomcat 版本来选择,不一定是 Tomcat 7.0;
我这里是演示添加 Tomcat,当然也可以选择添加 IBM 的 Liberty ,或者 JBoss 之类的 Web 服务器(Java EE容器)
如果你还没有安装 Tomcat,那可以去官网下载一个压缩包解压到一个目录就可以了。
4、点击 Browse 按钮选择 Tomcat 所在的位置
选择 JRE (Java Runtime Environment),当然你可以使用 Eclipse 自带的,
但如果你想使用自己安装的版本就需要添加一下;初学使用自带的就可以了;
5、上面一切就绪点击 Finish 按钮就可以了。
