今天导入一个项目后出现：
Multiple annotations found at this line:
- String cannot be resolved to a type
- No exception of type ServletException can be thrown; an exception type must be a
subclass of Throwable
- The method getContextPath() from the type HttpServletRequest refers to the missing type
String
- java.io.IOException cannot be resolved to a type
- The type java.util.Map cannot be resolved. It is indirectly referenced from required .class
files
然后就是一大堆jsp文件报错:
解决办法：
一：
找到Libraries下面报错的包，移除掉。
二:
三、如果以上步骤以后还是不行的话继续下一步：
右击项目，选择Java Build Path>Libraries>Add External JARS,找到你计算机中的tomcat的安装路径，在common/lib文件夹下，选中"servlet-api.jar"和“jsp-api.jar”,添加点击“确定”,就行了
