1. Dependency and database settings

Org.springframework.boot spring-boot-starter-data-redis org.apache.commons commons-pool2 org.springframework.boot spring-boot-starter- Web org.springframework.session spring-session-data-redis org.springframework.boot spring-boot-starter-test test Spring.redis.database=0 spring.redis.host=localhostspring.redis.port=6379 spring.redis.password=123 # your own password 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 and session configuration

@ Configuration@EnableCachingpublic class RedisConfig extends CachingConfigurerSupport {@ 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 () }};} @ Configuration@EnableRedisHttpSession (maxInactiveIntervalInSeconds = 86400 / 30) public class SessionConfig {}

3. Entity and controller layer

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= "user-key") public User getUser () {User user=new User ("aa@126.com", "aa", "aa123456", "aa", "123"); System.out.println ("Test Cache"); 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 ();}}

4. Running

@ SpringBootApplicationpublic class RedisApplication {public static void main (String [] args) {SpringApplication.run (RedisApplication.class, args);}}

Running result:
