前言

什么是局部刷新?

简而言之,就是当我发送一个请求到后端后拿到数据后返回当前 页面不会对整个页面进行重载而只对当前请求的模块进行刷新。

优势和弊端?

优势:

弊端:

实现流程

案列

首先我们需要先右键new一个springboot项目

配置pom依赖:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.7.2</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>demo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>demo</name>
    <description>demo</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

配置yml文件

server:
  port: 8080
# Spring配置
spring:
  # 模板引擎
  thymeleaf:
    # 禁用缓存
    cache: false
    prefix: classpath:/templates/
    suffix: .html
    mode: HTML
    encoding: utf-8

编写接口:

package com.example.demo.web;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import java.util.ArrayList;
import java.util.List;

/**
 * @Program: demo
 * @ClassName WebController
 * @Author: LiuTao
 * @Description: SpringBoot+thymeleaf+ajax实现局部刷新测试接口类
 * @Create: 2022-07-24 0:29
 * @Version 1.0
 **/
@Controller
public class WebController {
    /**
     * @methodName: list
     * @description: 测试接口
     * @Author LiuTao
     * @param  [model]
     * @updateTime 2022/7/24 0:33
     * @return java.lang.String
     * @throws
     **/
    @RequestMapping("/list")
    public String list(Model model) {
        List lists = new ArrayList();
        lists.add("aaaa");
        lists.add("bbbb");
        lists.add("cccc");
        lists.add("dddd");
        model.addAttribute("list",lists);
        return "index::list";
    }
}

在templates包下新建一个index.html

<!DOCTYPE html>
<html lang="en" xmlns:th="http://www.thymeleaf.org">
<head>
    <meta charset="UTF-8" />
    <title>Title</title>
    <script th:src="@{/jquery.min.js}"></script>
</head>
<body>
<button onclick="list()">获取列表</button>

<table border="1" th:fragment="list" id="list" >
    <thead>
        <th>用户</th>
    </thead>
    <tr th:each="list:${list}">
        <td>[[${list}]]</td>
    </tr>
</table>
</body>
<script>
    function list(){
        //第一种方法
        // $('#search').load("/list");
        //第二种方法
        $.ajax({
            url: "/list",
            type: 'POST',
            success: function (data) {
                $("#list").html(data);
            }
        })
    }
</script>
</html>
