11分钟学会SpringBoot整合redis组件
不要跟过去的自己比,要期待未来的自己,珍爱现在的自己
1.添加Redis相关依赖
<!--Redis相关依赖-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-redis</artifactId>
</dependency>
2.application.properties中redis相关配置
# Redis数据库索引(默认为0)
spring.redis.database=0
# Redis服务器地址
spring.redis.host=127.0.0.1
# Redis服务器连接端口
spring.redis.port=6379
# Redis服务器连接密码(默认为空)
spring.redis.password=
# 连接池最大连接数(使用负值表示没有限制)
spring.redis.jedis.pool.max-active=200
# 连接池最大阻塞等待时间(使用负值表示没有限制)
spring.redis.jedis.pool.max-wait=-1
# 连接池中的最大空闲连接
spring.redis.jedis.pool.max-idle=10
# 连接池中的最小空闲连接
spring.redis.jedis.pool.min-idle=10
# 连接超时时间(毫秒)
spring.redis.timeout=1000
3.redis自定义配置
SpringBoot自动在容器中生成了一个
RedisTemplate
和一个StringRedisTemplate
第一种:(添加方式添加配置)
@Configuration
public class MyRedisConfig {
/**
* 修改默认序列化得方式为Json解析
**/
@Bean
public RedisTemplate<Object, Employee> empRedisTemplate(
RedisConnectionFactory redisConnectionFactory)
throws UnknownHostException {
RedisTemplate<Object, Employee> template = new RedisTemplate<Object, Employee>();
template.setConnectionFactory(redisConnectionFactory);
Jackson2JsonRedisSerializer<Employee> ser = new Jackson2JsonRedisSerializer<Employee>(Employee.class);
template.setDefaultSerializer(ser);
return template;
}
@Bean
public RedisTemplate<Object, Department> deptRedisTemplate(
RedisConnectionFactory redisConnectionFactory)
throws UnknownHostException {
RedisTemplate<Object, Department> template = new RedisTemplate<Object, Department>();
template.setConnectionFactory(redisConnectionFactory);
Jackson2JsonRedisSerializer<Department> ser = new Jackson2JsonRedisSerializer<Department>(Department.class);
template.setDefaultSerializer(ser);
return template;
}
//CacheManagerCustomizers可以来定制缓存的一些规则
@Primary //将某个缓存管理器作为默认的
@Bean
public RedisCacheManager employeeCacheManager(RedisTemplate<Object, Employee> empRedisTemplate){
RedisCacheManager cacheManager = new RedisCacheManager(empRedisTemplate);
//key多了一个前缀
//使用前缀,默认会将CacheName作为key的前缀
cacheManager.setUsePrefix(true);
return cacheManager;
}
@Bean
public RedisCacheManager deptCacheManager(RedisTemplate<Object, Department> deptRedisTemplate){
RedisCacheManager cacheManager = new RedisCacheManager(deptRedisTemplate);
//key多了一个前缀
//使用前缀,默认会将CacheName作为key的前缀
cacheManager.setUsePrefix(true);
return cacheManager;
}
}
第二种:(重写redisTemplate)
@Configuration
public class RedisConfig {
@Bean
@SuppressWarnings("all")
public RedisTemplate<String, Object> redisTemplate(RedisConnectionFactory factory) {
RedisTemplate<String, Object> template = new RedisTemplate<String, Object>();
template.setConnectionFactory(factory);
Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);
ObjectMapper om = new ObjectMapper();
om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);
om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);
jackson2JsonRedisSerializer.setObjectMapper(om);
StringRedisSerializer stringRedisSerializer = new StringRedisSerializer();
// key采用String的序列化方式
template.setKeySerializer(stringRedisSerializer);
// hash的key也采用String的序列化方式
template.setHashKeySerializer(stringRedisSerializer);
// value序列化方式采用jackson
template.setValueSerializer(jackson2JsonRedisSerializer);
// hash的value序列化方式采用jackson
template.setHashValueSerializer(jackson2JsonRedisSerializer);
template.afterPropertiesSet();
return template;
}
}
