Answer 1

阅读您的日志说，找不到 apache commons 日志记录类.. 因此，在您的库中添加 apache commons 的 jar 日志。 在这里你可以得到那个 jar http://mvnrepository.com/artifact/commons-logging/commons-logging

SEVERE: Servlet /springornek threw load() exception java.lang.ClassNotFoundException: org.apache.commons.logging.LogFactory at

注意:使用 maven 或 gradle 为您简化构建项目的依赖关系。
