springboot使用Redis作缓存使用入门教程

1.依赖与数据库设置

<dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-data-redis</artifactId></dependency><dependency><groupId>org.apache.commons</groupId><artifactId>commons-pool2</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency><dependency><groupId>org.springframework.session</groupId><artifactId>spring-session-data-redis</artifactId></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><scope>test</scope></dependency>

spring.redis.database=0 spring.redis.host=localhostspring.redis.port=6379 spring.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{@Beanpublic 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.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;}@Overridepublic 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('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(); }}

4.运行

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

运行结果：

同时也可以用专门的图形界面工具查看：
