SpringBoot中配置redis的序列化方式(使用jackson序列化方式)

1.声明

当前内容用于本人复习和使用redis,主要用于配置redis的值的序列化方式jackson
这里借助spring

2.配置pom文件

<parent>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-parent</artifactId>
	<version>2.2.5.RELEASE</version>
	<relativePath /> <!-- lookup parent from repository -->
</parent>
<dependency>
	<groupId>org.springframework.boot</groupId>
	<artifactId>spring-boot-starter-redis</artifactId>
	<version>1.4.7.RELEASE</version><!-- 这里如果出现NoSuchMethod就表示可能当前的版本有问题 -->
</dependency>

这个在启动的时候出现了一个问题：NoSuchMethod(主要原因当前的spring-boot的配置与当前的spring-boot-starter-redis版本导致的错误)

3.配置RedisConfig这个配置类

@Configuration
@PropertySource(value = "redis.properties")
@ConditionalOnClass({ RedisConnectionFactory.class, RedisTemplate.class })
public class RedisConfig {

	@Value("${redis.maxIdle}")
	private Integer maxIdle;

	@Value("${redis.maxTotal}")
	private Integer maxTotal;

	@Value("${redis.maxWaitMillis}")
	private Long maxWaitMillis;

	@Value("${redis.testOnBorrow}")
	private Boolean testOnBorrow;

	private JedisPoolConfig jedisPoolConfig() {
		JedisPoolConfig config = new JedisPoolConfig();
		config.setMaxIdle(maxIdle);
		config.setMaxTotal(maxTotal);
		config.setMaxWaitMillis(maxWaitMillis);
		config.setTestOnBorrow(testOnBorrow);
		return config;
	}

	@Value("${redis.host}")
	private String redisHost;

	@Value("${redis.port}")
	private String redisPort;

	@Value("${redis.password}")
	private String password;

	@Value("${redis.timeout}")
	private Integer timeout;


	/**
	 * @description 创建redis连接工厂
	 */
	@SuppressWarnings("deprecation")
	private JedisConnectionFactory jedisConnectionFactory() {
		JedisConnectionFactory factory = new JedisConnectionFactory(new JedisShardInfo(redisHost, redisPort));
		factory.setPassword(password);
		factory.setTimeout(timeout);
		factory.setPoolConfig(jedisPoolConfig());
		factory.setUsePool(true);
		return factory;
	}

	/**
	 * @description 创建RedisTemplate 的操作类
	 */
	@Bean
	public RedisTemplate<String, Object> getRedisTemplate() {
		RedisTemplate<String, Object> redisTemplate = new RedisTemplate<String, Object>();
		redisTemplate.setConnectionFactory(jedisConnectionFactory());
		redisTemplate.setKeySerializer(keySerializer());
		redisTemplate.setValueSerializer(valueSerializer());
		redisTemplate.setHashKeySerializer(keySerializer());
		redisTemplate.setHashValueSerializer(valueSerializer());
		redisTemplate.setEnableTransactionSupport(true);
		return redisTemplate;
	}
	
	// 创建redis的key序列化规则
	private RedisSerializer<?> keySerializer() {
		return new StringRedisSerializer();
	}

	// 值使用jackson进行序列化
	private RedisSerializer<?> valueSerializer() {
		return new GenericJackson2JsonRedisSerializer();
		// return new JdkSerializationRedisSerializer();
	}

}

这里通过spring-data-redis的GenericJackson2JsonRedisSerializer实现序列化

配置文件：

redis.maxTotal=10
redis.maxIdle=5
redis.maxWaitMillis=2000
redis.testOnBorrow=true
redis.host=localhost
redis.port=6379
redis.timeout=0
redis.password=
redis.usePool=true
redis.testWhileIdle=true
