SpringBoot整合redis

1、导入依赖

　　　　　<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

2、在linux系统下启动redis

　　

3、配置文件application.yml

spring:
  datasource:
    driver-class-name: com.mysql.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/user?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone = GMT
    username: root
    password: 123

　redis:
    host: 192.168.124.197
    port: 6379

4、测试类

@RunWith(SpringRunner.class)
@SpringBootTest(classes = DemoApplication.class)
public class Apptest {
　　//redis
    @Autowired
    private RedisTemplate redisTemplate;

    @Test
    public void test02(){
        redisTemplate.opsForValue().set("hello","java");
        String str = (String) redisTemplate.opsForValue().get("hello");
        System.out.println(str);
        MUser user=new MUser(1,"admin","123");
        redisTemplate.opsForValue().set("user",user);
        MUser user1 = (MUser)redisTemplate.opsForValue().get("user");
        System.out.println(user1);
    }
}

5、注意其中若是引用pojo对象时，该pojo对象需要实现序列化接口。

　　如是没有实现接口，就会报一个错误：

　　　　org.springframework.data.redis.serializer.SerializationException: Cannot serialize...
