[Java知识库]springboot整合redis的使用

一、先创建springboot项目，然后添加相关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>2.7.1</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>cn.tedu</groupId>
    <artifactId>redisdemo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>redisdemo</name>
    <description>Demo project for Spring Boot</description>
    <properties>
        <java.version>1.8</java.version>
    </properties>
    <dependencies>
        <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>
    <!--集成redis-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>
    <!--lombok，来自动生成get，set等方法-->
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.18.10</version>
            <scope>compile</scope>
        </dependency>
    </dependencies>

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

</project>

二、配置连接redis的application.yml文件?

spring:
  redis:
    host: 127.0.0.1
    port: 6379
server:
  port: 8083

三、启动redis并连接?

3.1 进入到安装redis的目录下

3.2 使用命令启动并去连接?

四、测试连接：做一个基本的连接测试?

package cn.tedu.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

/**
 * @Classname RedisController
 * @Description TODO
 * @Date 2022/6/24 11:57
 * @Author 朱文龙
 */
@RestController
@RequestMapping("/redis")
public class RedisController {
    @Autowired
    private StringRedisTemplate template;
    @GetMapping("/hello")
    public String hello(String name,String age){
      template.opsForValue().set(name,age);
        String value = template.opsForValue().get(name);
        System.out.println(name+","+value);
        return name+","+value;
    }
}

在浏览器中访问该项目地址，运行效果如下图，说明redis已连接成功，并且获取数据也成功了！http://localhost:8083/redis/hello?name=%E5%B0%8F%E6%9D%8E%E5%A4%B4&age=23?

五、通过对象的方式来进行数据的保存与读取。在项目中新增一个User类

package cn.tedu.pojo;

import lombok.Data;
import lombok.experimental.Accessors;

/**
 * @Classname User
 * @Description TODO
 * @Date 2022/6/24 14:53
 * @Author 朱文龙
 */
@Data
@Accessors(chain = true)
public class User {
    private String name;
    private Integer age;
    private String Gender;
}

测试代码如下图：

   @GetMapping("/user")
    public String getUser(){
        List<User> userList = new ArrayList<>();
        userList.add(new User().setName("小李头").setAge(23).setGender("女"));
        userList.add(new User().setName("小白").setAge(20).setGender("男"));
        userList.add(new User().setName("张三").setAge(30).setGender("男"));
        userList.add(new User().setName("小法师").setAge(15).setGender("女"));
        template.opsForValue().set("user", String.valueOf(userList));
        System.out.println(template.opsForValue().get("user"));
        return template.opsForValue().get("user");
    }

通过访问地址 http://localhost:8083/redis/user?，最后运行效果如下图 :
