先在拦截器里执行方法看一看结果
System.out.println("getRequestURI:"+request.getRequestURI());
System.out.println("getRequestURL:"+request.getRequestURL());
System.out.println("getContextPath:"+request.getContextPath());
System.out.println("getServletPath:"+request.getServletPath());
结果：
getRequestURI:/user/index
getRequestURL:http://localhost/user/index
getContextPath:
getServletPath:/user/index
总结：
request.getRequestURL()和request.getRequestURI()
