심각: 경로가 []인 컨텍스트의 서블릿 [member.servlet.memberInsertServlet]을(를) 위한 Servlet.service() 호출이 예외를 발생시켰습니다.java.lang.NullPointerException at exServlet.util.UserSHA256.getSHA256(UserSHA256.java:14) at member.servlet.memberInsertServlet.doPost(memberInsertServlet.java:45) at javax.servlet.http.HttpServlet.service(HttpServlet.java:681) at javax.servlet.http.HttpServlet.service(HttpServlet.java:764) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:232) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:167) at org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:194) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:167) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:202) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:97) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:544) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:143) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:81) at org.apache.catalina.valves.AbstractAccessLogValve.invoke(AbstractAccessLogValve.java:698) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:78) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:364) at org.apache.coyote.http11.Http11Processor.service(Http11Processor.java:624) at org.apache.coyote.AbstractProcessorLight.process(AbstractProcessorLight.java:65) at org.apache.coyote.AbstractProtocol$ConnectionHandler.process(AbstractProtocol.java:831) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.doRun(NioEndpoint.java:1651) at org.apache.tomcat.util.net.SocketProcessorBase.run(SocketProcessorBase.java:49) at java.util.concurrent.ThreadPoolExecutor.runWorker(Unknown Source) at java.util.concurrent.ThreadPoolExecutor$Worker.run(Unknown Source) at org.apache.tomcat.util.threads.TaskThread$WrappingRunnable.run(TaskThread.java:61) at java.lang.Thread.run(Unknown Source) 이렇게 나옵니다 ㅠㅠ

저번에 성공했었던 서블릿문을 그대로 가져왔는데 저번에는 됐었거든요..다른점은 이번에는 sha256을 사용했다는건데.. sha256도 강사님께서 주신 파일 그대로라 문제는 없구요..

아니.. 로그 찍으면서 혼자 확인해보세요.. 그것만 알아도 이런 문제 다 해결합니다 ;;
