### 一、创建一个简单的maven工程spring-boot-jquery ###

### 二、在webapp目录下分别添加文件hello.js、index.html，文件内容分别如下： ###

$(document).ready(function() {
        $.ajax({
            url: "http://rest-service.guides.spring.io/greeting"
        }).then(function(data) {
           $('.greeting-id').append(data.id);
           $('.greeting-content').append(data.content);
        });
    });

<!DOCTYPE html>
    <html>
        <head>
            <title>Hello jQuery</title>
            <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>
            <script src="hello.js"></script>
        </head>
    
        <body>
            <div>
                <p class="greeting-id">The ID is </p>
                <p class="greeting-content">The content is </p>
            </div>
        </body>
    </html>

### 三、打开postman，查看请求[http://rest-service.guides.spring.io/greeting][http_rest-service.guides.spring.io_greeting] ###

{
        "id": 2236,
        "content": "Hello, World!"
    }

### 四、将spring-boot-jquery添加到tomcat，启动tomcat ###
