在升級(jí)springboot3.x后啟動(dòng)項(xiàng)目發(fā)現(xiàn)redis連接報(bào)錯(cuò)了，根據(jù)堆棧異常信息發(fā)現(xiàn)redis竟然去鏈接了本地服務(wù)，該項(xiàng)目使用了Nacos配置也都在上，突然的異常感覺挺奇怪的，本來以為是升級(jí)后無法拉取到Nacos的配置信息了后經(jīng)驗(yàn)證使用@Value注解或者其他配置類均未發(fā)生該問題，那就只能懷疑是spring對(duì)redis的配置支持改變了，所以直接點(diǎn)就去找了redis的自動(dòng)配置類發(fā)現(xiàn)確實(shí)改變了配置前綴為spring.data.redis（原該項(xiàng)目springboot版本為2.7.4時(shí)redis配置前綴為spring.redis）貼一下版本屬性內(nèi)容對(duì)比圖
3.x版本時(shí)：
@ConfigurationProperties(prefix = "spring.data.redis")
public class RedisProperties {
/**
* Database index used by the connection factory.
*/
private int database = 0;
/**
* Connection URL. Overrides host, port, and password. User is ignored. Example:
* redis://user:password@example.com:6379
*/
private String url;
/**
* Redis server host.
*/
private String host = "localhost";
/**
* Login username of the redis server.
*/
private String username;
/**
* Login password of the redis server.
*/
private String password;
/**
* Redis server port.
*/
private int port = 6379;
/**
* Whether to enable SSL support.
*/
private boolean ssl;
/**
* Read timeout.
*/
private Duration timeout;
/**
* Connection timeout.
*/
private Duration connectTimeout;
/**
* Client name to be set on connections with CLIENT SETNAME.
*/
private String clientName;
/**
* Type of client to use. By default, auto-detected according to the classpath.
*/
private ClientType clientType;
private Sentinel sentinel;
private Cluster cluster;
private final Jedis jedis = new Jedis();
private final Lettuce lettuce = new Lettuce();
}2.7.4版本時(shí)：
@ConfigurationProperties(prefix = "spring.redis")
public class RedisProperties {
/**
* Database index used by the connection factory.
*/
private int database = 0;
/**
* Connection URL. Overrides host, port, and password. User is ignored. Example:
* redis://user:password@example.com:6379
*/
private String url;
/**
* Redis server host.
*/
private String host = "localhost";
/**
* Login username of the redis server.
*/
private String username;
/**
* Login password of the redis server.
*/
private String password;
/**
* Redis server port.
*/
private int port = 6379;
/**

*/
private boolean ssl;
/**

private Duration timeout;
/**

*/
private Duration connectTimeout;
/**

private final Jedis jedis = new Jedis();
private final Lettuce lettuce = new Lettuce();
}至此問題解決。
