项目中加入redis

在spring的配置文件中加入redis的配置：

<bean id="jedisPoolConfig" class="redis.clients.jedis.JedisPoolConfig">
            <property name="maxTotal" value="200" />
            <property name="maxIdle" value="100" />
            <property name="timeBetweenEvictionRunsMillis" value="30000" />
            <property name="minEvictableIdleTimeMillis" value="30000" />
            <property name="testOnBorrow" value="true" />
        </bean>
    
        
        <bean id="jedisPool" class="redis.clients.jedis.JedisPool">
            <constructor-arg index="0" ref="jedisPoolConfig" />
            <constructor-arg index="1" value="127.0.0.1" name="host" type="java.lang.String" />
            <constructor-arg index="2" value="6379" name="port" type="int" />
            <constructor-arg index="3" value="5000" name="timeout" type="int" />
            <constructor-arg index="4" value="" name="password" type="java.lang.String" />
        </bean>
    
        <bean id="jedisConnectionFactory" class="org.springframework.data.redis.connection.jedis.JedisConnectionFactory" scope="singleton">
            <property name="hostName" value="127.0.0.1" />
            <property name="port" value="6379" />
            <property name="password" value="" />
            <property name="timeout" value="100000" />
            <property name="poolConfig" ref="jedisPoolConfig" />
            <property name="usePool" value="true" />
        </bean>
    
        <bean id="redisTemplate" class="org.springframework.data.redis.core.RedisTemplate">
            <property name="connectionFactory" ref="jedisConnectionFactory" />
            <property name="keySerializer">
                <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
            </property>
            <property name="hashKeySerializer">
                <bean class="org.springframework.data.redis.serializer.StringRedisSerializer" />
            </property>
            <property name="valueSerializer">
                <bean class="org.springframework.data.redis.serializer.JdkSerializationRedisSerializer" />
            </property>
        </bean>
        
        <bean id="redisTemplateUtils" class="com.redis.RedisTemplateUtils">
            <property name="redisTemplate" ref="redisTemplate" />
        </bean>

自定义的工具类RedisTemplateUtils，用来编写java代码时，需要向redis存入或者取出数据时方便操作，这个写的不全，是为了测试写的，可以自己上网上抄一个全的，嘿嘿：

package com.redis;
    
    import org.springframework.data.redis.core.RedisTemplate;
    import org.springframework.data.redis.core.SetOperations;
    import org.springframework.data.redis.core.ZSetOperations;
    /** * * @author HKY * */
    public class RedisTemplateUtils { 
    
        private RedisTemplate<String, String> redisTemplate;
    
        /** * 用于spring注入. * @param redisTemplate */
        public void setRedisTemplate(RedisTemplate<String, String> redisTemplate) {
            this.redisTemplate = redisTemplate;
        }
    
        /** * 获取模板redis对象. * @return */
        public RedisTemplate<String, String> getRedisTemplate() {
            return redisTemplate;
        }
    
    
        /** * zSet有序集合，默认按照score升序排列，存储格式K(1)==V(n)，V(1)=S(1)(K=key,V=value,S=score) * @param key * 键 * @param value * 值 * @param number * 插入序号 * @return */
        public  Boolean zSet(String key, String value, Integer score) {
            Boolean result;
            ZSetOperations<String, String> zSet = redisTemplate.opsForZSet();
            result = zSet.add(key, value, score);
            if (result) {
                System.out.println("zset存储成功");
            }else {
                System.out.println("zset存储失败");
            }
            return result;
        }
    
        /** * 无序集合，add的顺序不是存储顺序 * @param key * @param values * @return */
        public Long set(String key, String... values) {
            Long result;
            SetOperations<String, String> set = redisTemplate.opsForSet();
            result = set.add(key, values);
            if (result != null) {
                System.out.println("set存储成功");
            }else {
                System.out.println("set存储失败");
            }
            return result;
        }
    }

当然， 也可以直接在项目中调用原始的redisTemplate，但是要把它用spring注入。。恶心了，貌似不要那样做的好！自己玩玩就行了。。。

**测试：**

@Autowired
        private RedisTemplateUtils redisUtils;
        private void goTest(){
            redisUtils.set("hh", "hahah");
            redisUtils.zSet("kk", "gogo", 0);
            System.out.println("ok");
        }
