1.引入redis的启动器
<dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency>
2.指定redis的主机地址
3.自动注入模板
@Autowired StringRedisTemplate stringRedisTemplate; //k v都是字符串的 @Autowired RedisTemplate<Object, Object> redisTemplate; //k v都是对象的
redsiAutoConfiguration:
// // Source code recreated from a .class file by IntelliJ IDEA // (powered by Fernflower decompiler) // package org.springframework.boot.autoconfigure.data.redis; import java.net.UnknownHostException; import org.springframework.boot.autoconfigure.condition.ConditionalOnClass; import org.springframework.boot.autoconfigure.condition.ConditionalOnMissingBean; import org.springframework.boot.context.properties.EnableConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.context.annotation.Import; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisOperations; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.core.StringRedisTemplate; @Configuration @ConditionalOnClass({RedisOperations.class}) @EnableConfigurationProperties({RedisProperties.class}) @Import({LettuceConnectionConfiguration.class, JedisConnectionConfiguration.class}) public class RedisAutoConfiguration { public RedisAutoConfiguration() { } @Bean @ConditionalOnMissingBean( name = {"redisTemplate"} ) public RedisTemplate<Object, Object> redisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException { RedisTemplate<Object, Object> template = new RedisTemplate(); template.setConnectionFactory(redisConnectionFactory); return template; } @Bean @ConditionalOnMissingBean public StringRedisTemplate stringRedisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException { StringRedisTemplate template = new StringRedisTemplate(); template.setConnectionFactory(redisConnectionFactory); return template; } }
@Test public void test01(){ stringRedisTemplate.opsForValue().append("k2","_append_k2"); }
测试保存对象:
@Test public void test02(){ User user = new User(); user.setId(36); user.setAddress("上海市黄浦区赵家桥285号"); user.setAge(21); user.setSex(1); user.setName("包青天"); redisTemplate.opsForValue().set("usr1",user);//默认以java序列化的形式保存 }
添加配置，使其能以json的数据形式存入redis中：
package ustc.anmin.springboot.service; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.data.redis.connection.RedisConnectionFactory; import org.springframework.data.redis.core.RedisTemplate; import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer; import ustc.anmin.springboot.bean.User; import java.net.UnknownHostException; @Configuration public class MyRedisConfig { @Bean public RedisTemplate<Object, User> userRedisTemplate(RedisConnectionFactory redisConnectionFactory) throws UnknownHostException { RedisTemplate<Object, User> template = new RedisTemplate(); //关键 template.setDefaultSerializer(new Jackson2JsonRedisSerializer<User>(User.class)); template.setConnectionFactory(redisConnectionFactory); return template; } }
将redis设为缓存中间件：
1.在pom.xml中引入redis的starter
2.将数据格式转为json形式 要修改redisManager
@Bean public CacheManager cacheManager(RedisConnectionFactory redisConnectionFactory) { //初始化一个RedisCacheWriter RedisCacheWriter redisCacheWriter = RedisCacheWriter.nonLockingRedisCacheWriter(redisConnectionFactory); //设置CacheManager的值序列化方式为json序列化 RedisSerializer<Object> jsonSerializer = new GenericJackson2JsonRedisSerializer(); RedisSerializationContext.SerializationPair<Object> pair = RedisSerializationContext.SerializationPair .fromSerializer(jsonSerializer); RedisCacheConfiguration defaultCacheConfig=RedisCacheConfiguration.defaultCacheConfig() .serializeValuesWith(pair); //设置默认超过期时间是30秒 defaultCacheConfig.entryTtl(Duration.ofSeconds(30)); //初始化RedisCacheManager return new RedisCacheManager(redisCacheWriter, defaultCacheConfig); }
其余设置与spring-boot启动缓存的方式一样。
