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

2023-08-24 15:45:52

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 = 1.8

repositories {

    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
