有一段时间没做jsp了,今天想深入一下tomcat服务器,maven项目时,jsp的index的页面报个错:
The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build
根据提示中文意思是说,javax.servlet.http.HttpServlet类在java构建时没有找到
解决方法如下:
1.选中项目名称,点击右键选择buildpath 》 config buildpath
弹出如下对话框
单击右边栏的Add Labrary,弹出如下对话框
点击 Server Runtime,继续弹出下面的对话框
选择配置过的http服务器,此处以tomcat为例
最后点击finish,ok项目刷新后,jsp的红色波浪线不见了,说明这个错误解决了。
当然还有一个更为简单的方法就是在项目pom文件中添加servelet.jar的依赖,然后刷新项目。
