springboot集成redis 附redis基本操作类

1 pom.xml添加依赖　　　

 <dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-redis</artifactId>
<version>1.4.7.RELEASE</version>
</dependency>


application.properties

# spring redis
spring.redis.host=127.0.0.1
spring.redis.port=6379
#spring.redis.database=0
spring.redis.pool.max-idle=100
spring.redis.pool.min-idle=1
spring.redis.pool.max-active=1000
spring.redis.pool.max-wait=3000

2 新建一个配置类

import java.io.Serializable;  
import java.lang.reflect.Method;

import org.springframework.context.annotation.Bean;  
import org.springframework.context.annotation.Configuration;  
import org.springframework.data.redis.cache.RedisCacheManager;  
import org.springframework.data.redis.connection.RedisConnectionFactory;  
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.data.redis.serializer.JdkSerializationRedisSerializer;
import org.springframework.data.redis.serializer.StringRedisSerializer;  
  
@Configuration  
@EnableCaching  
public class RedisConfig extends CachingConfigurerSupport {  
    @Bean  
    public KeyGenerator biliKeyGenerator(){  
        return new KeyGenerator() {  
  
            @Override  
            public Object generate(Object target, Method method, Object... params) {  
                StringBuilder sb = new StringBuilder();  
                sb.append(target.getClass().getName());  
                sb.append(method.getName());  
                for (Object obj : params) {  
                    sb.append(obj.toString());  
                }  
                return sb.toString();  
            }  
        };  
  
    }  
  
    @Bean  
    public CacheManager cacheManager(@SuppressWarnings("rawtypes") RedisTemplate redisTemplate) {  
        return new RedisCacheManager(redisTemplate);  
    }  
    @Bean  
    public RedisTemplate<Serializable, Serializable> redisTemplate(RedisConnectionFactory redisConnectionFactory) {  
        RedisTemplate<Serializable, Serializable> redisTemplate = new RedisTemplate<Serializable, Serializable>();  
        redisTemplate.setConnectionFactory(redisConnectionFactory);  
        redisTemplate.setKeySerializer(new StringRedisSerializer()); //在其他项目中请保持序列化统一 否则会出现取值类型不一的异常
        redisTemplate.setValueSerializer(new JdkSerializationRedisSerializer());
        return redisTemplate;  
    }  
}
