spring boot中使用resid-RedisTemplate

1、项目中导入依赖jar包 这里用的maven

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

2、项目配置文件设置redis信息 这里用的 yml配置文件 

redis: host:  port:  password:  pool:  max-active: 8  min-idle: 0  max-idle: 8  max-wait: 10000 timeout: 0database: 9

注意 要在spring：节点下

3、在项目中新建类 让spring boot启动时加载  RedisTemplate

package com.prairie.manage.config;import com.fasterxml.jackson.annotation.JsonAutoDetect;import com.fasterxml.jackson.annotation.PropertyAccessor;import com.fasterxml.jackson.databind.ObjectMapper;import org.springframework.cache.CacheManager;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.core.RedisTemplate;import org.springframework.data.redis.core.StringRedisTemplate;import org.springframework.data.redis.serializer.Jackson2JsonRedisSerializer;import java.lang.reflect.Method;/** * Created by xxx on 2017/6/25. * 加载redis配置信息 */@Configuration@EnableCachingpublic class RedisConfiguration {    @Bean    public KeyGenerator keyGenerator() {        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();            }        };    }    @SuppressWarnings("rawtypes")    @Bean    public CacheManager cacheManager(RedisTemplate redisTemplate) {        RedisCacheManager rcm = new RedisCacheManager(redisTemplate);        //设置缓存过期时间        //rcm.setDefaultExpiration(60);//秒        return rcm;    }    @Bean    public RedisTemplate<String, String> redisTemplate(RedisConnectionFactory factory) {        StringRedisTemplate template = new StringRedisTemplate(factory);        Jackson2JsonRedisSerializer jackson2JsonRedisSerializer = new Jackson2JsonRedisSerializer(Object.class);        ObjectMapper om = new ObjectMapper();        om.setVisibility(PropertyAccessor.ALL, JsonAutoDetect.Visibility.ANY);        om.enableDefaultTyping(ObjectMapper.DefaultTyping.NON_FINAL);        jackson2JsonRedisSerializer.setObjectMapper(om);        template.setValueSerializer(jackson2JsonRedisSerializer);        template.afterPropertiesSet();        return template;    }}

4、新建redisService 实现具体操作redis

@Componentpublic class RedisService {    @Autowired    private RedisTemplate<String, String> redisTemplate;    /**     * key value 形式     * @param key     * @param value     */    @SuppressWarnings({"unchecked", "rawtypes"})    public void set(final String key, final String value) {        redisTemplate.execute(new RedisCallback() {            public Long doInRedis(RedisConnection connection) throws DataAccessException {                connection.set(key.getBytes(), value.getBytes());                return 1L;            }        });    }    /**     * set 一个有时间的key 到时间后自动过期     * @param key     * @param value     * @param liveTime  存活时间/秒     */    @SuppressWarnings({"unchecked", "rawtypes"})    public void set(final String key, final String value, final long liveTime) {        redisTemplate.execute(new RedisCallback() {            public Long doInRedis(RedisConnection connection) throws DataAccessException {                connection.setEx(key.getBytes(), liveTime, value.getBytes());                return 1L;            }        });    }    /**     * 根据key 获取value     * @param key     * @return     */    @SuppressWarnings({"unchecked", "rawtypes"})    public String get(final String key) {        return (String) redisTemplate.execute(new RedisCallback() {            public Object doInRedis(RedisConnection connection) throws DataAccessException {                try {                    return new String(connection.get(key.getBytes()));                } catch (Exception e) {                }                return null;            }        });    }    /**     * 自增  key不存在则为1 key存在则自增     * @param key     */    @SuppressWarnings({"unchecked", "rawtypes"})    public void incrby(final String key) {        redisTemplate.execute(new RedisCallback() {            public Long doInRedis(RedisConnection connection) throws DataAccessException {                Long incr = connection.incr(key.getBytes());                return incr;            }        });    }    /**     *  自增不存在数值会默认初始化0然后加1，传入时间后自动销毁     * @param key     * @param liveTime     */    public void incrby(final String key,final long liveTime) {        redisTemplate.execute(new RedisCallback<Object>() {            public Long doInRedis(RedisConnection connection) throws DataAccessException {                Long incr = connection.incr(key.getBytes());                connection.expire(key.getBytes(), liveTime);                return incr;            }        });    }    /**     * 自减     * @param key     */    @SuppressWarnings({"unchecked", "rawtypes"})    public void decrby(final String key) {        redisTemplate.execute(new RedisCallback() {            public Long doInRedis(RedisConnection connection) throws DataAccessException {                Long incr = connection.decr(key.getBytes());                return incr;            }        });    }    /**     * 删除key的value     * @param key     */    public void del(final String key){        redisTemplate.execute(new RedisCallback<Object>(){            public Long doInRedis(RedisConnection connection) throws DataAccessException {                return connection.del(key.getBytes());            }        });    }    /**     * 根据key查看是否存在 刷新     * @param key     * @return     */    public boolean hasKey(String key){       return redisTemplate.hasKey(key);    }    /**     * 根据key刷新过期时间     * @param key     * @param timeOut     * @return     */    public boolean refreshLiveTime(String key,long timeOut){        return redisTemplate.expire(key,timeOut, TimeUnit.SECONDS);    }}
