本文详细介绍了如何在Spring Boot项目中整合Redis，包括配置依赖、连接池、模板以及实现基本的CRUD操作。通过示例代码，展示了如何进行数据的存取、设置过期时间和删除等常见操作。

1.在pom中配置redis的相关依赖包：

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-redis</artifactId>
    <version>1.3.8.RELEASE</version>
</dependency>

2.在application.yml里面配置redis的配置项

spring:
  redis:
        host: 127.0.0.1
        port: 8979
        password:
        pool:
          max-active: 100
          max-idle: 10
          max-wait: 100000
        timeout: 0

3.使用RedisTemplate操作redis

RedisConfig.java

@Configuration
@EnableAutoConfiguration
public class RedisConfig {
    //获取JedisPoolConfig配置
    @Bean
    @ConfigurationProperties(prefix = "spring.redis.pool")
    public JedisPoolConfig getRedisConfig(){
        JedisPoolConfig config = new JedisPoolConfig();
        return config;
    }
//获取JedisConnectionFactory工厂
    @Bean
    //读取配置文件的信息
    @ConfigurationProperties(prefix = "spring.redis")
    public JedisConnectionFactory getConnectionFactory() {
        JedisConnectionFactory factory = new JedisConnectionFactory();
        factory.setUsePool(true);
        int port =factory.getPort();
        System.out.println("factory1223123123123123"+port);
        JedisPoolConfig config = getRedisConfig();
        factory.setPoolConfig(config);
        return factory;
    }
//获取RedisTemplate模板。
    @Bean
    public RedisTemplate<?, ?> getRedisTemplate() {
        JedisConnectionFactory factory = getConnectionFactory();
        RedisTemplate<?, ?> template = new StringRedisTemplate(factory);
        return template;
    }
}

RedisService.java

public interface RedisService {
    /**
     * set存数据
     * @param key
     * @param value
     * @return
     */
    boolean set(String key, String value);

    /**
     * get获取数据
     * @param key
     * @return
     */
    String get(String key);

    /**
     * 设置有效天数
     * @param key
     * @param expire
     * @return
     */
    boolean expire(String key, long expire);

    /**
     * 移除数据
     * @param key
     * @return
     */
    boolean remove(String key);

RedisServiceImpl

@Service("redisService")
public class RedisServiceImpl implements RedisService {
    @Resource
    private RedisTemplate<String, ?> redisTemplate;

    @Override
    public boolean set(final String key, final String value) {
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
            @Override
            public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
                RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
                connection.set(serializer.serialize(key), serializer.serialize(value));
                return true;
            }
        });
        return result;
    }

    @Override
    public String get(final String key) {
        String result = redisTemplate.execute(new RedisCallback<String>() {
            @Override
            public String doInRedis(RedisConnection connection) throws DataAccessException {
                RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
                byte[] value = connection.get(serializer.serialize(key));
                return serializer.deserialize(value);
            }
        });
        return result;
    }

    @Override
    public boolean expire(final String key, long expire) {
        return redisTemplate.expire(key, expire, TimeUnit.SECONDS);
    }

    @Override
    public boolean remove(final String key) {
        boolean result = redisTemplate.execute(new RedisCallback<Boolean>() {
            @Override
            public Boolean doInRedis(RedisConnection connection) throws DataAccessException {
                RedisSerializer<String> serializer = redisTemplate.getStringSerializer();
                connection.del(key.getBytes());
                return true;
            }
        });
        return result;
    }


}

测试类

RedisTests.java

@RunWith(SpringRunner.class)
@SpringBootTest
public class RedisTests{

@Autowired
private RedisService redisService;

@Test
public void contextLoads() throws Exception {
}


/**
 * 插入字符串
 */
@Test
public void setString() {
    redisService.set("redis_string_test", "springboot redis test");
}

/**
 * 获取字符串
 */
@Test
public void getString() {
    String result = redisService.get("redis_string_test");
    System.out.println(result);
}
