使用spring boot，gradle，idea，js，html创建一个小的前后端程序

1：配置build.gradle,添加依赖等

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath('org.springframework.boot:spring-boot-gradle-plugin:1.5.9.RELEASE')
    }
}
group "com.li"
version "1.0-SNAPSHOT"
apply plugin: "java"                           //java 插件
apply plugin: "org.springframework.boot"   //spring boot 插件
apply plugin: "io.spring.dependency-management"
apply plugin: "application"   //应用
//mainClassName = "Main.Application"
sourceCompatibility = 1.8repositories {
    mavenCentral()
}dependencies {
    compile("org.springframework.boot:spring-boot-starter-web",
            "org.springframework.boot:spring-boot-starter-activemq",
            "org.springframework.boot:spring-boot-starter-test",
            "org.springframework.boot:spring-boot-starter-cache",
            "org.springframework.boot:spring-boot-devtools")
    runtime ("org.apache.tomcat.embed:tomcat-embed-jasper")
    testCompile group: 'junit', name: 'junit', version: '4.12'
}

2：配置application.properties, 因为只用到前端控制器，也可以不配置任何内容

# 配置启动端口号
#server.port=8080
# 配置返回视图的前缀和后缀
#spring.mvc.view.prefix=/html/
#spring.mvc.view.suffix=.html

3：创建后台映射

package com.li.controller;import com.li.pojo.Order;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;import java.util.ArrayList;
import java.util.List;@Controller
public class LoginController {
    @RequestMapping("/orderTest")
    @ResponseBody
    public List order(String orderNo,String sortFiled) {
        List list=new ArrayList();
        Order order=new Order();
        order.setHotelName("name");
        order.setHotelSeq("123");
        list.add(order);
        return list;
    }}

4：pojo类Order.java

package com.li.pojo;public class Order {    public String hotelSeq;    public String getHotelSeq() {
        return hotelSeq;
    }    public void setHotelSeq(String hotelSeq) {
        this.hotelSeq = hotelSeq;
    }    public String getHotelName() {
        return hotelName;
    }    public void setHotelName(String hotelName) {
        this.hotelName = hotelName;
    }    public String hotelName;}

5:springboot启动类

package com.li;import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication
public class SpringBootHtmlApplication {
    public static void main(String[] args){
        SpringApplication.run(SpringBootHtmlApplication.class, args);
    }
}

6：创建前台html页面

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <title>xx信息查询</title>
</head><body>
<div class="main pusher">
    <form class="ui form vertical segment form-search">
        <img src="/yujinxiang.jpg"  alt="上海鲜花港 - 郁金香" />  <!--加载图片-->
        <div class="fields">
            <div class="sixCl wide field js_query_seq">
                <label>订单号</label>
                <input type="text" maxlength="50" name="orderNo" id="orderNo" placeholder="">
            </div>
            <!--https://blog.csdn.net/dreamweaver_zhou/article/details/79203297-->
            <div class="sixCl wide field js_query_btype">
                <label>排序字段</label>
                <select name="sortFiled" id="sortFiled">
                    <option value="order_no">订单号</option>
                </select>
            </div>            <div>
                <label></label>
                <input type="button" value="搜索" id="btSearch" class="ui right floated positive button btn-search"/>
            </div>        </div>
    </form>    <div class="table-container">
        <table class="ui nine column table celled table-result" id="table-result">
            <thead>
            <tr>
                <th>hotelSeq</th>
                <th>酒店名称</th>
            </tr>
            </thead>            <tbody id="tbody-result">
            </tbody>        </table>
    </div>
<script type="text/javascript" src="https://code.jquery.com/jquery-3.2.0.js"></script>
<script type="text/javascript" src="./js/cheatorder.js"></script>
<!--<script type="text/javascript" src="http://code.jquery.com/jquery-1.11.3.min.js"></script>--></div>
</body>
</html>

7：js代码

$(function() {
    $('#btSearch').click(function () {
        var orderNo = $('#orderNo').val();
        var sortFiled = $('#sortFiled').val();
        var tbody=window.document.getElementById("tbody-result");
        $.ajax({
            type: "post",
            dataType: "json",
            url: "/orderTest",
            data: {
                orderNo: orderNo,
                sortFiled: sortFiled
            },
            success: function (msg) {    //请求成功之后的操作
//                if (msg.ret) {
                    var str = "";
//                    var data = msg.data;
                    var data1=msg[0];
//                    for (i in data) {
                        str += "<tr>" +
                        "<td>" + data1.hotelSeq + "</td>" +
                        "<td>" + data1.hotelName + "</td>" +
                        "</tr>";
//                    }
                    tbody.innerHTML = str;
//                }
            },
            error: function () {
                alert("查询失败")
            }
        });
    });
});

8：开启服务，浏览器访问

http://localhost:8080/order.html

出现

9：输入订单号，点击搜索，搜索到结果，前台显示
