配置文件配置数据库，redis等相关的信息。
# See http://docs.spring.io/spring-boot/docs/current/reference/html/common-application-properties.html # Thymeleaf配置 spring.thymeleaf.cache=false spring.thymeleaf.mode=HTML spring.main.show-banner=false spring.thymeleaf.prefix=classpath:/templates spring.thymeleaf.suffix=.html logging.level.jdbc=OFF logging.level.jdbc.sqltiming=DEBUG logging.level.jdbc.resultsettable=DEBUG # 数据库配置 spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.url=jdbc:mysql://127.0.0.1:3306/taotao?useSSL=false spring.datasource.username=root spring.datasource.password=root # 日志配置 logging.config=classpath:logback-spring.xml logging.level.root=info # MyBatis配置 mybatis.type-aliases-package=cn.hzr0523.entity mybatis.mapper-locations=classpath:mapper/*.xml #Redis Cluster spring.redis.host=127.0.0.1 spring.redis.port=6379 spring.redis.password=123456 spring.redis.maxTotal=30 USER_SESSION_KEY=REDIS_USER_SESSION SSO_SESSION_EXPIRE=30接着，是jedisConfig的配置，采用java配置方式，取代了xml配置，也是Spring Boot推荐的一种配置方式。
package cn.hzr0523.service.impl; import org.springframework.beans.factory.annotation.Value; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Configuration; import redis.clients.jedis.JedisPool; import redis.clients.jedis.JedisPoolConfig; @Configuration public class JedisConfig { @Value("${spring.redis.maxTotal}") public Integer maxTotal; @Value("${spring.redis.host}") public String host; @Value("${spring.redis.port}") public Integer port; @Value("${spring.redis.password}") public String password; @Bean public JedisPoolConfig jedisPoolConfig() { JedisPoolConfig jedisPoolConfig = new JedisPoolConfig(); jedisPoolConfig.setMaxTotal(maxTotal); return jedisPoolConfig; } @Bean public JedisPool jedisPool() { JedisPool jedisPool = new JedisPool(jedisPoolConfig(), host, port, 30, password); return jedisPool; } } 接下来jedis工具类的编码：
package cn.hzr0523.service; public interface JedisClient { String get(String key); String set(String key, String value); String hget(String hkey, String key); long hset(String hkey, String key, String value); long incr(String key); long expire(String key, int second); long ttl(String key); long del(String key); long hdel(String hkey, String key); } package cn.hzr0523.service.impl; import cn.hzr0523.service.JedisClient; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Component; import org.springframework.stereotype.Service; import redis.clients.jedis.Jedis; import redis.clients.jedis.JedisPool; /** * 单个redis */ @Service public class JedisClientSingle implements JedisClient { @Autowired private JedisPool jedisPool; @Override public String get(String key) { Jedis jedis = jedisPool.getResource(); String string = jedis.get(key); jedis.close(); return string; } @Override public String set(String key, String value) { Jedis jedis = jedisPool.getResource(); String string = jedis.set(key, value); jedis.close(); return string; } @Override public String hget(String hkey, String key) { Jedis jedis = jedisPool.getResource(); String string = jedis.hget(hkey, key); jedis.close(); return string; } @Override public long hset(String hkey, String key, String value) { Jedis jedis = jedisPool.getResource(); Long result = jedis.hset(hkey, key, value); jedis.close(); return result; } @Override public long incr(String key) { Jedis jedis = jedisPool.getResource(); Long result = jedis.incr(key); jedis.close(); return result; } @Override public long expire(String key, int second) { Jedis jedis = jedisPool.getResource(); Long result = jedis.expire(key, second); jedis.close(); return result; } @Override public long ttl(String key) { Jedis jedis = jedisPool.getResource(); Long result = jedis.ttl(key); jedis.close(); return result; } @Override public long del(String key) { Jedis jedis = jedisPool.getResource(); Long result = jedis.del(key); jedis.close(); return result; } @Override public long hdel(String hkey, String key) { Jedis jedis = jedisPool.getResource(); Long result = jedis.hdel(hkey, key); jedis.close(); return result; } } 接下来就可以使用redis了
public ResultObject userLogin(UserDTO userDTO, HttpServletRequest request, HttpServletResponse response) { ResultObject resultObject = new ResultObject(); if (userDTO == null) { resultObject.setResultCode("0"); resultObject.setResultMessage("参数错误"); return resultObject; } //根据登录信息查询学员信息 TbUser user = userMapper.getUserInfo(userDTO.getUserName(), userDTO.getPassword()); if (user == null) { resultObject.setResultCode("0"); resultObject.setResultMessage("用户名或密码错误"); return resultObject; } //登录成功，把用户信息写入redis //String s = jedisClientSingle.get(USER_SESSION_KEY); //logger.info("USER_SESSION_KEY: " + s); //生成一个用户token String token = UUID.randomUUID().toString(); logger.info(JSONObject.toJSONString(user)); jedisClient.set(USER_SESSION_KEY + ":" + token, JSONObject.toJSONString(user)); //设置session过期时间 jedisClient.expire(USER_SESSION_KEY + ":" + token, SSO_SESSION_EXPIRE); //添加写cookie的逻辑，cookie的有效期是关闭浏览器就失效。 CookieUtils.setCookie(response, "TT_TOKEN", token, -1); //返回token resultObject.setResultCode("1"); resultObject.setResultMessage("登录成功"); resultObject.setResultData(token); return resultObject; }简单小demo，也是参考别人写的，在编写过程中也遇到了一些问题，包括redis的安装，jedis的使用。有错才能成长，大家一起进步。
