在Spring Boot整合Redis時(shí),可能會(huì)遇到各種異常。為了更好地處理這些異常,我們可以采用以下幾種方法:
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(RedisConnectionFailureException.class)
public ResponseEntity<String> handleRedisConnectionFailure(RedisConnectionFailureException ex) {
// 處理Redis連接失敗的異常
return new ResponseEntity<>("Redis連接失敗: " + ex.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
}
@ExceptionHandler(RedisDataException.class)
public ResponseEntity<String> handleRedisDataError(RedisDataException ex) {
// 處理Redis數(shù)據(jù)操作的異常
return new ResponseEntity<>("Redis數(shù)據(jù)操作失敗: " + ex.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
}
}
@Service
public class RedisService {
public String getValue(String key) {
try (Jedis jedis = jedisPool.getResource()) {
return jedis.get(key);
} catch (RedisConnectionFailureException ex) {
// 處理Redis連接失敗的異常
System.err.println("Redis連接失敗: " + ex.getMessage());
} catch (RedisDataException ex) {
// 處理Redis數(shù)據(jù)操作的異常
System.err.println("Redis數(shù)據(jù)操作失敗: " + ex.getMessage());
}
return null;
}
}
# application.properties
logging.level.org.springframework.data.redis=DEBUG
logging.level.com.example=DEBUG
或者
# application.yml
logging:
level:
org.springframework.data.redis: DEBUG
com.example: DEBUG
通過(guò)以上方法,我們可以更好地處理Spring Boot整合Redis時(shí)可能遇到的異常。
