springboot对于redis的增删改查

1.下载redis，安装之后，打开redis服务器。不过有绿色版的，直接打开redis服务器可执行文件，启动redis服务器。

2.在pom.xml配置文件中添加redis依赖包

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
<version>1.3.8.RELEASE</version>
</dependency>

3.在application.properties配置文件中添加redis配置信息

#spring redis
spring.redis.host=localhost
spring.redis.port=6379
spring.redis.database=0
spring.redis.password=root
spring.redis.pool.max-active=8
spring.redis.pool.max-wait=-1
spring.redis.pool.max-idle=8
spring.redis.pool.min-idle=0
spring.redis.timeout=0

4.新建一个config包，创建RedisConfig配置类

package springboot.redis.config;
import org.springframework.cache.CacheManager;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.data.redis.cache.RedisCacheManager;
import org.springframework.data.redis.connection.RedisConnectionFactory;
import org.springframework.data.redis.core.RedisTemplate;

@Configuration
@EnableCaching//开启注解
public class RedisConfig extends CachingConfigurerSupport {
@Bean
public CacheManager cacheManager(RedisTemplate<?,?> redisTemplate) {
CacheManager cacheManager = new RedisCacheManager(redisTemplate);
return cacheManager;
}

@Bean
public RedisTemplate<String, String> redisTemplate(Re
4000
disConnectionFactory factory) {
RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();
redisTemplate.setConnectionFactory(factory);
return redisTemplate;
}

}

5.新建一个services包，创建一个RedisService接口

package springboot.redis.services;

public interface RedisService {

//add
public void set(String id, String name);
//select
public String get(String id);
//update
public void update(String id,String name);
//delete
public void delete(String id);
}

6.在services包中，新建一个impl包，在impl包中新建一个RedisServiceImpl实现类

package springboot.redis.services.impl;
import javax.annotation.Resource;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import org.springframework.stereotype.Service;
import springboot.redis.services.RedisService;

@Service
public class RedisServiceImpl implements RedisService {

@Resource
private RedisTemplate<String, String> redisTemplate;
@Override
public void set(String id, String name) {
ValueOperations<String,String> vo = redisTemplate.opsForValue();
vo.set(id, name);
}

@Override
public String get(String id) {
ValueOperations<String, String> vo=redisTemplate.opsForValue();
return vo.get(id);
}

@Override
public void update(String id, String name) {
ValueOperations<String,String> vo=redisTemplate.opsForValue();
vo.set(id, name);

}

@Override
public void delete(String id) {
ValueOperations<String, String> vo=redisTemplate.opsForValue();
vo.getOperations().delete(id);
}

}

7.新建一个control包，创建一个RedisControl类

package springboot.redis.control;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import springboot.redis.services.impl.RedisServiceImpl;

@RestController
@RequestMapping("/redis")
public class RedisControl {

@Autowired
private RedisServiceImpl redisServiceImpl;
//设置redis中的key和value
@RequestMapping("/add")
public String setRedis(String id,String name){
redisServiceImpl.set(id, name);
return "redis设置成功"+"id="+id+" name="+name;

}
//获得redis中的value
@RequestMapping("/select")
public String getRedis(String id){
return "redis获得值成功"+"name="+redisServiceImpl.get(id);
}
//修改redis中的value
@RequestMapping("/update")
public String updateRedis(String id,String name){
redisServiceImpl.update(id, name);
System.out.println("修改成");
return "redis修改成功"+"id="+id+" name="+redisServiceImpl.get(id);
}
//修改redis中的value
@RequestMapping("/delete")
public String deleteRedis(String id,String name){
redisServiceImpl.delete(id);
return "redis删除成功";
}

}

8.springboot启动类

package springboot;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;
//import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
import org.springframework.session.data.redis.config.annotation.web.http.EnableRedisHttpSession;
import redis.clients.jedis.Jedis;

@SpringBootApplication
@EnableRedisHttpSession
public class SpringbootApplication {

public static void main(String[] args) {
SpringApplication app=new SpringApplication(SpringbootApplication.class);
app.run(args);
Jedis jedis = new Jedis("localhost");
jedis.auth("root");
jedis.save();
}
}

9.启动之后

新增数据 http://127.0.0.1:8080/redis/add?id=1&name=张三


查询数据 http://127.0.0.1:8080/redis/select?id=1


修改数据 http://127.0.0.1:8080/redis/update?id=1&name=李四


查询修改数据 http://127.0.0.1:8080/redis/select?id=1


删除数据 http://127.0.0.1:8080/redis/delete?id=1
