SpringBoot整合Redis开发RESTful API接口

开发环境

  SpringBoot版本：2.0.5.RELEASE、jdk版本：1.8+、Maven版本：3.5.4

配置文件

在SpringBoot里的application.properties文件中配置Redis信息

# REDIS (RedisProperties)
# Database index used by the connection factory.
spring.redis.database=0

# Redis server host.
spring.redis.host=localhost

# Login password of the redis server.
spring.redis.password=

# Redis server port.
spring.redis.port=6379

# Maximum number of connections that can be allocated by the pool at a given time. Use a negative value for no limit.
spring.redis.lettuce.pool.max-active=8

# Maximum number of "idle" connections in the pool. Use a negative value to indicate an unlimited number of idle connections.
spring.redis.lettuce.pool.max-idle=8

# Maximum amount of time a connection allocation should block before throwing an exception when the pool is exhausted. Use a negative value to block indefinitely.
spring.redis.lettuce.pool.max-wait=-1ms

# Target for the minimum number of idle connections to maintain in the pool. This setting only has an effect if it is positive.
spring.redis.lettuce.pool.min-idle=0

# Shutdown timeout.
spring.redis.lettuce.shutdown-timeout=100ms

Redis有两种连接方式：一个是Jedis，另一个是Lettuce。它俩间的区别：使用Jedis，如果多线程使用同一个连接，线程时不安全的，需要使用连接池，为每一个Jedis实例分配一个连接；而使用Lettuce，当多线程连接同一个连接实例时，是线程安全的。
SpringBoot2.0以后，默认的连接方式是Lettuce，我这里使用的也是Lettuce，首先添加Redis包：

  org.springframework.boot
  spring-boot-starter-data-redis

如果使用的是Jedis连接，需要修改一下配置：

	org.springframework.boot
	spring-boot-starter-data-redis
	
		
			io.lettuce
			lettuce-core
		
	


	redis.clients
	jedis

建立连接

    
    @Bean
    public LettuceConnectionFactory connectionFactory() {
 LettuceConnectionFactory lettuceConnectionFactory = new LettuceConnectionFactory();
 lettuceConnectionFactory.setDatabase(redisConfigBean.getDatabase());
 lettuceConnectionFactory.setHostName(redisConfigBean.getHost());
 lettuceConnectionFactory.setPassword(redisConfigBean.getPassword());
 lettuceConnectionFactory.setPort(redisConfigBean.getPort());

 return lettuceConnectionFactory;
    }

效果演示

• POST请求：设置ContentType=application/json，添加RequestBody中的内容，格式为Json格式
  
• GET请求
• PUT请求：设置ContentType=application/json，修改RequestBody中的内容，格式为Json格式
  
• DELETE请求
