Multiple annotations found at this line: - String cannot be resolved to a type

报错内容:

Multiple annotations found at this line:
- String cannot be resolved to a type
- The method getContextPath() from the type HttpServletRequest refers to the missing type String

报错原因:

由于项目迁移,之前的系统的jre与本机的jre版本不同,所以要删除之前的jre库,改用本机的jre库;

解决办法:

首先 右击该项目 - Build Path - Configure Build Path , 在 Libraries 选项下,会发现有个出错的jre Libraries,将其Remove掉。

然后 右击该项目 - Build Path - Add Library, 选择JRE System Library,选择Workspace defaulr JRE(jdk1.6)(此前JDK已成功安装并配置好), 然后 Finish 。
