Investigation:
Caused by: java.lang.NoSuchMethodError: javax.servlet.ServletContext.getClassLoader()Ljava/lang/ClassLoader;
根据这条错误显示，猜测是java servlet不匹配issue. 联想到当前的eclipse用的是刚new的tomcat 8，可能是项目servlet-api.jar 同tomcat 8 不匹配。
最终解决方法，删除项目工程lib文件夹的低版本的servlet-api.jar, tomcat 8的lib文件夹里用默认带的jar包
或者把tomcat换成7。
