默认配置文件：application.properties

# REDIS (RedisProperties)# Redis数据库索引（默认为0）spring.redis.database=0# Redis服务器地址spring.redis.host=localhost# Redis服务器连接端口spring.redis.port=6379# Redis服务器连接密码（默认为空）spring.redis.password=# 连接池最大连接数（使用负值表示没有限制）spring.redis.pool.max-active=8# 连接池最大阻塞等待时间（使用负值表示没有限制）spring.redis.pool.max-wait=-1# 连接池中的最大空闲连接spring.redis.pool.max-idle=8# 连接池中的最小空闲连接spring.redis.pool.min-idle=0# 连接超时时间（毫秒）spring.redis.timeout=0

序列化的user对象

public class User implements Serializable {    private static final long serialVersionUID = -1L;    private String username;    private Integer age;    public User(String username, Integer age) {        this.username = username;        this.age = age;    }    public String getUsername() {        return username;    }    public void setUsername(String username) {        this.username = username;    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }}

测试StringRedisTemplate和RedisTemplate

@RunWith(SpringRunner.class)@SpringBootTestpublic class RedisTest {    @Autowired    private StringRedisTemplate stringRedisTemplate;    @Autowired    private RedisTemplate<String, User> redisTemplate;    @Test    public void test() throws Exception {        // 保存字符串        stringRedisTemplate.opsForValue().set("aaa", "111");        Assert.assertEquals("111", stringRedisTemplate.opsForValue().get("aaa"));    }    @Test    public void test1() throws Exception {        // 保存对象        User user = new User("超人", 20);        redisTemplate.opsForValue().set(user.getUsername(), user);        user = new User("蝙蝠侠", 30);        redisTemplate.opsForValue().set(user.getUsername(), user);        user = new User("蜘蛛侠", 40);        redisTemplate.opsForValue().set(user.getUsername(), user);        Assert.assertEquals(20, redisTemplate.opsForValue().get("超人").getAge().longValue());        Assert.assertEquals(30, redisTemplate.opsForValue().get("蝙蝠侠").getAge().longValue());        Assert.assertEquals(40, redisTemplate.opsForValue().get("蜘蛛侠").getAge().longValue());    } }
