这是一个Springboot项目中整合Redis的示例。
1.引入依赖
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
<dependency>
<groupId>org.apache.commons</groupId>
<artifactId>commons-pool2</artifactId>
</dependency>
2.Spring配置文件
application.yml
内容如下:
spring:
redis:
host: 178.128.150.98 # Redis服务器地址
database: 0 # Redis数据库索引(默认为0)
port: 6379 # Redis服务器连接端口
password: 4spaces.org # Redis服务器连接密码(默认为空)
timeout: 1000ms # 连接超时时间
lettuce:
pool:
max-active: 8
max-wait: -1
max-idle: 8
min-idle: 0
3.新建配置类
package com.ddmit.redis.config;
import org.springframework.cache.annotation.CachingConfigurerSupport;
import org.springframework.cache.annotation.EnableCaching;
import org.springframework.cache.interceptor.KeyGenerator;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import java.lang.reflect.Method;
@Configuration
@EnableCaching
public class RedisConfig extends CachingConfigurerSupport {
@Bean
public KeyGenerator keyGenerator() {
return new KeyGenerator() {
@Override
public Object generate(Object target, Method method, Object... params) {
StringBuilder sb = new StringBuilder();
sb.append(target.getClass().getName());
sb.append(method.getName());
for (Object obj : params) {
sb.append(obj.toString());
}
return sb.toString();
}
};
}
}
4.Springboot单元测试
package com.ddmit.redis;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.core.StringRedisTemplate;
import org.springframework.data.redis.core.ValueOperations;
import javax.annotation.Resource;
@SpringBootTest
class RedisApplicationTests {
@Autowired
private StringRedisTemplate stringRedisTemplate;
@Autowired
private RedisTemplate redisTemplate;
@Resource(name = "stringRedisTemplate")
private ValueOperations<String, String> sops;
@Test
public void test() throws Exception {
stringRedisTemplate.opsForValue().set("aaa", "111");
System.out.println(stringRedisTemplate.opsForValue().get("aaa"));
System.out.println(sops.get("aaa"));
}
}
5.代码结构

楼主大宝宝听的那个asmr网站发我呗
如果是买的美国地域的,那是不是节点就只有美国的?
