springboot集成redis

Posted 2020-11-22 逆水乘舟，不进则退

1.配置文件如下

spring:
# 热部署
devtools:
restart:
enabled: true #设置开启热部署
additional-paths: src/main/java #重启目录
exclude: WEB-INF/**
freemarker:
cache: false #页面不加载缓存，修改即时生效
# redis
redis:
host: 192.168.0.6
port: 6479
timeout: 5000 # 连接超时时间（毫秒）
# password:
pool:
minIdle: 0 # 连接池中的最小空闲连接
maxIdle: 8 # 连接池中的最大空闲连接
maxWait: -1 # 连接池最大阻塞等待时间（使用负值表示没有限制）
maxActive: 8 # 连接池最大连接数（使用负值表示没有限制）

 2.引入data-redisjar包

<!--redis-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>

3.写redis配置类

@Configuration
@ConditionalOnClass(RedisOperations.class)
@EnableConfigurationProperties(RedisProperties.class)
public class RedisConfig {

@Bean
@ConditionalOnMissingBean(name = "redisTemplate")
public RedisTemplate<Object, Object> redisTemplate(
RedisConnectionFactory redisConnectionFactory) {
RedisTemplate<Object, Object> template = new RedisTemplate<>();
//使用fastjson序列化
FastJsonRedisSerializer fastJsonRedisSerializer = new FastJsonRedisSerializer(Object.class);
// value值的序列化采用fastJsonRedisSerializer
template.setValueSerializer(fastJsonRedisSerializer);
template.setHashValueSerializer(fastJsonRedisSerializer);
// key的序列化采用StringRedisSerializer
template.setKeySerializer(new StringRedisSerializer());
template.setHashKeySerializer(new StringRedisSerializer());
template.setConnectionFactory(redisConnectionFactory);
return template;
}

@Bean
@ConditionalOnMissingBean(StringRedisTemplate.class)
public StringRedisTemplate stringRedisTemplate(
RedisConnectionFactory redisConnectionFactory) {
StringRedisTemplate template = new StringRedisTemplate();
template.setConnectionFactory(redisConnectionFactory);
return template;
}

}

@GetMapping("/getdata")
public void getdata(){
//测试redis

redisUtil.set("name","小猫");
redisUtil.set("age", "11", 15);
System.out.println(redisUtil.getExpire("name"));
System.out.println( redisUtil.get("name"));
System.out.println(redisUtil.getExpire("age"));
System.out.println( redisUtil.get("age"));

}

4.配置好了写简单测试类
