springboot使用Redis作缓存使用入门教程 springboot使用Redis作缓存使用入

1.依赖与数据库设置

org.springframework.bootspring-boot-starter-data-redisorg.apache.commonscommons-pool2org.springframework.bootspring-boot-starter-weborg.springframework.sessionspring-session-data-redisorg.springframework.bootspring-boot-starter-testtest

spring.redis.database=0spring.redis.host=localhostspring.redis.port=6379spring.redis.password=123 #自己的密码spring.redis.lettuce.pool.max-active=8spring.redis.lettuce.pool.max-wait=-1spring.redis.lettuce.pool.max-idle=8spring.redis.lettuce.pool.min-idle=0

2.redis和session配置

@Configuration@EnableCachingpublic class RedisConfig extends CachingConfigurerSupport{ @Bean public KeyGenerator keyGenerator() {return new KeyGenerator() {@Overridepublic 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(); }}; }}@Configuration@EnableRedisHttpSession(maxInactiveIntervalInSeconds = 86400*30)public class SessionConfig {}

3.实体与controller层

public class User implements Serializable { private static final long serialVersionUID = 1L; private Long id; private String userName; private String password; private String email; private String nickname; private String regTime; public User() {super(); } public User(String email, String nickname, String password, String userName, String regTime) {super(); this.email = email; this.nickname = nickname; this.password = password; this.userName = userName; this.regTime = regTime; } public Long getId() {return id; } public void setId(Long id) {this.id = id; } public String getUserName() {return userName; } public void setUserName(String userName) {this.userName = userName; } public String getPassword() {return password; } public void setPassword(String password) {this.password = password; } public String getEmail() {return email; } public void setEmail(String email) {this.email = email; } public String getNickname() {return nickname; } public void setNickname(String nickname) {this.nickname = nickname; } public String getRegTime() {return regTime; } public void setRegTime(String regTime) {this.regTime = regTime; } @Override public String toString() {return "User{" +"id=" + id +", userName='" + userName + '\'' +", password='" + password + '\'' +", email='" + email + '\'' +", nickname='" + nickname + '\'' +", regTime='" + regTime + '\'' +'}'; }}

@RestControllerpublic class UserController {@RequestMapping("/getUser")@Cacheable(value="https://www.it610.com/article/user-key")public User getUser() {User user=new User("aa@126.com", "aa", "aa123456", "aa","123"); System.out.println("测试缓存"); return user; }@RequestMapping("/uid")String uid(HttpSession session) {UUID uid = (UUID) session.getAttribute("uid"); if (uid == null) {uid = UUID.randomUUID(); }session.setAttribute("uid", uid); return session.getId(); }}
