在Spring Boot中处理HBase异常,可以通过以下几种方法:
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(HBaseConnectionException.class)
public ResponseEntity<String> handleHBaseConnectionException(HBaseConnectionException ex) {
// 处理HBase连接异常
return new ResponseEntity<>(ex.getMessage(), HttpStatus.INTERNAL_SERVER_ERROR);
}
@ExceptionHandler(HBaseQueryException.class)
public ResponseEntity<String> handleHBaseQueryException(HBaseQueryException ex) {
// 处理HBase查询异常
return new ResponseEntity<>(ex.getMessage(), HttpStatus.BAD_REQUEST);
}
}
public void someHBaseOperation() {
try {
// 执行HBase操作
} catch (HBaseConnectionException ex) {
// 处理HBase连接异常
log.error("HBase connection error: ", ex);
} catch (HBaseQueryException ex) {
// 处理HBase查询异常
log.error("HBase query error: ", ex);
}
}
public class HBaseConnectionException extends RuntimeException {
private int errorCode;
public HBaseConnectionException(String message, int errorCode) {
super(message);
this.errorCode = errorCode;
}
// getter和setter方法
}
public class HBaseQueryException extends RuntimeException {
private int errorCode;
public HBaseQueryException(String message, int errorCode) {
super(message);
this.errorCode = errorCode;
}
// getter和setter方法
}
spring:
hbase:
client:
config:
connection-timeout: 5000
retry-count: 3
通过以上方法,可以在Spring Boot应用中有效地处理HBase异常。
