相隔很久,我又回来了,献上一篇整合 redis 的教程给新手看一下吧,技术点不怎么有,最简单的配置,入手即用,那下面开始
本章在我的上一篇文章为基础继续整合的,不知道的可以见我的整合 tkmapper
springboot 整合 tkmapper
1、下面开始引入 pom 依赖
<!-- springboot 整合 redis -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
2、yml 文件根据自己配置添加 redis 信息
spring:
redis:
host: 127.0.0.1
database: 0
password: redis
port: 6379
timeout: 60000
3、HelloController 代码,用户访问接口测试 redis
package com.cxt.demo.controller;
import com.cxt.demo.service.HelloService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Repository;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @author liBai
* @Classname HelloController
* @Description TODO
* @Date 2019-06-02 10:49
*/
@RestController
@RequestMapping("/test")
public class HelloController {
@Autowired
private HelloService helloService;
@RequestMapping("/hello")
public String hello(){return helloService.sayHello();
}
@RequestMapping("/get")
public String getRedisInfo(){return helloService.getRedisInfo();
}
}
4、HelloService 代码
package com.cxt.demo.service;
/**
* @author liBai
* @Classname HelloService
* @Description TODO
* @Date 2019-06-02 10:49
*/
public interface HelloService {String sayHello();
String getRedisInfo();}
impl
package com.cxt.demo.service.impl;
import com.cxt.demo.bean.TestSys;
import com.cxt.demo.dao.TestSysMapper;
import com.cxt.demo.service.HelloService;
import lombok.extern.slf4j.Slf4j;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.stereotype.Service;
import java.util.concurrent.TimeUnit;
/**
* @author liBai
* @Classname HelloServiceImpl
* @Description TODO
* @Date 2019-06-02 10:50
*/
@Service
@Slf4j
public class HelloServiceImpl implements HelloService {
@Autowired
private TestSysMapper testSysMapper;
@Autowired
private StringRedisTemplate redisTemplate;
@Override
public String sayHello() {TestSys testSys = testSysMapper.selectByPrimaryKey("1");
redisTemplate.opsForValue().set("testSys",testSys.toString(),10,TimeUnit.MINUTES);
log.info("redis set value =" +testSys.toString());
return "redis set value success,userName ="+testSys.getName();}
@Override
public String getRedisInfo() {log.debug("redis get info {}",redisTemplate.opsForValue().get("testSys"));
return redisTemplate.opsForValue().get("testSys");
}
}
5、到这初级版本整合就可以使用了,正常项目中不可能这么简单使用 redis,毕竟 redis 的用处还是很强大的,例如单机,集群,哨兵等,具体的配置就自己挖掘吧,或者继续关注我后续的文章,下面就来演示一下这节的成果吧
浏览器访问
http://localhost:8081/test/hello
上面已经看到 redis 放入字符串已经放进去了,下面就拿出来试试吧
访问
http://localhost:8081/test/get
到了这基本也就结束了,有问题欢迎留言讨论,如有错误请指出一起交流,谢谢!
