이 두개의 에러가 무엇때문인지 계속 찾다가 결국에는 알아냈다.

org.apache.catalina.LifecycleException: Failed to start component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[]]

Caused by: java.lang.IllegalArgumentException: Filter mapping specifies an unknown filter name [encodingFilter]

원인은 filter-name 때문이다. encodingFilter인데 enconding 이라고 해서 에러가 계속 떴었던 것.....

즉, 스펠링 하나 잘못 넣어서 그런 것이였다ㅠㅠㅠ...휴...

일반적으로 name이라고 쓰는데는 마음대로 이름 넣어도 되는 줄 알았더니만 그게 아니였다는 사실!
