测试对象

import java.io.Serializable;

public class User implements Serializable {
    private static final long serialVersionUID = 3529219554011221820L;


    private String name;

    private Integer age;


    public User() {
    }

    public User(String name, Integer age) {
        this.name = name;
        this.age = age;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    @Override
    public String toString() {
        return "User{" +
                "name='" + name + '\'' +
                ", age=" + age +
                '}';
    }
}

单元测试

import com.qiuwei.common.demo.User;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.test.context.SpringBootTest;
import org.springframework.data.redis.core.RedisTemplate;
import org.springframework.test.context.junit4.SpringRunner;

@SpringBootTest
@RunWith(SpringRunner.class)
public class RedisTest {
    @Autowired
    private RedisTemplate redisTemplate;


    @Test
    public void redisTest() {
        // redis存储数据
        String key = "name";
        redisTemplate.opsForValue().set(key, "qiuwei");
        // 获取数据
        String value = (String) redisTemplate.opsForValue().get(key);
        System.out.println("key:" + key + ",value:" + value);

        User user = new User("qw",12);

        String userKey = "qiuwei";
        redisTemplate.opsForValue().set(userKey, user);
        User newUser = (User) redisTemplate.opsForValue().get(userKey);
        System.out.println("key:" + userKey + ",value:" + newUser);

    }
}
