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=localhost

spring.redis.port=6379  

spring.redis.password=123 #自己的密码

spring.redis.lettuce.pool.max-active=8

spring.redis.lettuce.pool.max-wait=-1

spring.redis.lettuce.pool.max-idle=8

spring.redis.lettuce.pool.min-idle=0

2.redis和session配置

@configuration
@enablecaching
public 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.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 + '\'' +
				'}';
	}
}

@restcontroller
public 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

@springbootapplication
public 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：
