如題，會出現Multiple annotations found at this line:
- java.io.IOException cannot be resolved to a type
- String cannot be resolved to a type
- java.io.IOException 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
- String cannot be resolved to a type
- java.io.IOException 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
甚至String cannot be resolved to a type這樣的各種錯誤，但專案在原機器上是正常執行的。
解決辦法兩個：
一：jdk不匹配。對方的jdk版本跟你的不同，甚至是1.6和1.7之間的差別，則必然出現這樣的錯誤。改成你自己的jdk就好。對專案右鍵properties->java build path之後就能找到了。
二：若不是這個問題，那試試project-clean。再不成功就很可能是程式碼問題或其他了。。
