Question

我尝试创建和部署一个restful Web Service，但是在部署时我无法调用任何方法。我试图在AWS上部署它＆＃39; Elastic Beanstalk，但是在部署时我无法访问欢迎页面之外的任何资源。

Netbeans识别方法，并将显示方法，（在这种情况下是一个简单的hello world方法，向用户返回一个字符串，告诉你好），如果我查看AWS访问日志，服务器正在接收请求，他们会不要看起来畸形。

它是一个在Tomcat 8上运行的Maven Web服务，我通过使用多个教程生成了以下内容，但是总是遇到无法调用该方法的相同问题，因为它只会导致404。

日志示例：

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns="http://java.sun.com/xml/ns/javaee"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
 version="3.0">

Index.jsp（最可能无关紧要，但无论如何都包括在内）：

    return "Hello world";

}
}
