1.POM配置
<!-- redis --> <dependency> <groupId>redis.clients</groupId> <artifactId>jedis</artifactId> <version>2.9.0</version> </dependency> <!-- spring-session --> <dependency> <groupId>org.springframework.session</groupId> <artifactId>spring-session-data-redis</artifactId> </dependency>
2.配置文件application.properties
# REDIS (RedisProperties) # Redis数据库索引(默认为0) spring.redis.database=0 # Redis服务器地址 spring.redis.host=localhost # Redis服务器连接端口 spring.redis.port=6379 # Redis服务器连接密码(默认为空) spring.redis.password=admin # 连接池最大连接数(使用负值表示没有限制) spring.redis.pool.max-active=8 # 连接池最大阻塞等待时间(使用负值表示没有限制) spring.redis.pool.max-wait=-1 # 连接池中的最大空闲连接 spring.redis.pool.max-idle=8 # 连接池中的最小空闲连接 spring.redis.pool.min-idle=0 # 连接超时时间(毫秒) spring.redis.timeout=0 #spring-session 使用 spring.session.store-type=none
3.redis链接池配置属性
package com.config; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Value; import org.springframework.cache.annotation.CachingConfigurerSupport; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import org.springframework.session.data.redis.config.ConfigureRedisAction; import redis.clients.jedis.JedisPool; import redis.clients.jedis.JedisPoolConfig; /** * Created by Administrator on 2017/5/9. */ @Configuration public class RedisConfig extends CachingConfigurerSupport { Logger logger = LoggerFactory.getLogger(RedisConfig.class); /** * SpringSession 需要注意的就是redis需要2.8以上版本,然后开启事件通知,在redis配置文件里面加上 * notify-keyspace-events Ex * Keyspace notifications功能默认是关闭的(默认地,Keyspace 时间通知功能是禁用的,因为它或多或少会使用一些CPU的资源)。 * 或是使用如下命令: * redis-cli config set notify-keyspace-events Egx * 如果你的Redis不是你自己维护的,比如你是使用阿里云的Redis数据库,你不能够更改它的配置,那么可以使用如下方法:在applicationContext.xml中配置 * <util:constant static-field="org.springframework.session.data.redis.config.ConfigureRedisAction.NO_OP"/> * @return */ @Bean public ConfigureRedisAction configureRedisAction() { return ConfigureRedisAction.NO_OP; } @Value("${spring.redis.host}") private String host; @Value("${spring.redis.port}") private int port; @Value("${spring.redis.timeout}") private int timeout; @Value("${spring.redis.pool.max-idle}") private int maxIdle; @Value("${spring.redis.pool.max-wait}") private long maxWaitMillis; @Value("${spring.redis.password}") private String password; @Bean public JedisPool redisPoolFactory() { logger.info("JedisPool注入成功!!"); logger.info("redis地址:" + host + ":" + port); JedisPoolConfig jedisPoolConfig = new JedisPoolConfig(); jedisPoolConfig.setMaxIdle(maxIdle); jedisPoolConfig.setMaxWaitMillis(maxWaitMillis); JedisPool jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout, password); // JedisPool jedisPool = new JedisPool(jedisPoolConfig, host, port, timeout); //无密码情况 return jedisPool; } }
redis工具类
package com.util; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; /** * Created by Administrator on 2017/5/9. */ @Component("redisClient") public class RedisClient { @Autowired private JedisPool jedisPool; public void set(String key, String value) throws Exception { Jedis jedis = null; try { jedis = jedisPool.getResource(); jedis.set(key, value); } finally { //返还到连接池 jedis.close(); } } public String get(String key) throws Exception { Jedis jedis = null; try { jedis = jedisPool.getResource(); return jedis.get(key); } finally { //返还到连接池 jedis.close(); } } }
redis应用
redisClient.set("redis_key", "abc"); String value=redisClient.get("redis_key"); logger.info("redis_key value:{}", value);
4.application 添加启用springsession注解
@EnableRedisHttpSession //spring session
和session一样正常使用即可
@RequestMapping("/setSession") public String setSession(HttpServletRequest request) throws Exception { request.getSession().setAttribute("user", "message"); return null; } @RequestMapping("/getSession") public String getSession(HttpServletRequest request) throws Exception { String message= (String)request.getSession().getAttribute("user"); logger.info("spring Session message:{}", message); return null; }
