redis+spring简单配置

1：填加pom.xml依赖

<dependency>      <groupId>org.springframework.data</groupId>      <artifactId>spring-data-redis</artifactId>      <version>1.6.0.RELEASE</version>  </dependency>  <dependency>      <groupId>redis.clients</groupId>      <artifactId>jedis</artifactId>      <version>2.7.3</version>  </dependency>

2:配置Redis的bean与spring集成

package com.lxd.shop.redis;import org.springframework.cache.CacheManager;import org.springframework.cache.annotation.CachingConfigurerSupport;import org.springframework.cache.annotation.EnableCaching;import org.springframework.cache.interceptor.KeyGenerator;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.connection.jedis.JedisConnectionFactory;import org.springframework.data.redis.core.RedisTemplate;import java.lang.reflect.Method;@Configuration@EnableCachingpublic class RedisCacheConfig extends CachingConfigurerSupport {    @Bean    public JedisConnectionFactory redisConnectionFactory() {        JedisConnectionFactory redisConnectionFactory = new JedisConnectionFactory();        redisConnectionFactory.setHostName("127.0.0.1");        redisConnectionFactory.setPort(6379);        return redisConnectionFactory;    }    @Bean    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory cf) {        RedisTemplate<String, String> redisTemplate = new RedisTemplate<String, String>();        redisTemplate.setConnectionFactory(cf);        return redisTemplate;    }    @Bean    public CacheManager cacheManager(RedisTemplate redisTemplate) {        RedisCacheManager cacheManager = new RedisCacheManager(redisTemplate);        // Number of seconds before expiration. Defaults to unlimited (0)        cacheManager.setDefaultExpiration(3000); // Sets the default expire time (in seconds)        return cacheManager;    }    @Bean    public KeyGenerator customKeyGenerator() {        return new KeyGenerator() {            @Override            public Object generate(Object o, Method method, Object... objects) {                StringBuilder sb = new StringBuilder();                sb.append(o.getClass().getName());                sb.append(method.getName());                for (Object obj : objects) {                    sb.append(obj.toString());                }                return sb.toString();            }        };    }}

并在将扫描的bean加入spring
<context:component-scan base-package="com.lxd.shop.redis" />

3:在service中加入缓存执行方法

@Cacheable("selectByPrimaryKey")    public ProductBind selectByPrimaryKey(String productBindId) {        // TODO Auto-generated method stub        return productBindMapper.selectByPrimaryKey(productBindId);    }

4：返回对象时需序列化对象为json格式

@JsonSerialize@JsonNaming(PropertyNamingStrategy.LowerCaseWithUnderscoresStrategy.class)  public class ProductBind implements Serializable{    private String productBindId;    private String productName;    private String itemNumber;    private Date createTime;    private Integer qrNumber;
