处理Spring Hibernate SQL错误的推荐方法

您可以定义自己的错误处理程序，该错误处理程序扩展了 ResponseEntityExceptionHandler
并捕获特定于数据库的异常。这是一个代码…

@RestControllerAdvice@RequestMapping(produces = "application/json")public class DefaultExceptionHandler extends ResponseEntityExceptionHandler {    // This method handles constraint violation exception raised by DB.     // Similarly other type exceptions like custom exception and HTTP status related     //exception can be handled here.    @ExceptionHandler(ConstraintViolationException.class)    @ResponseStatus(value = HttpStatus.CONFLICT)    public Map<String, String> handleConstraintViolationException(ConstraintViolationException ex) {    // write your own logic to return user friendly response    }   // Below method is to handle _SqlExceptionHelper_ exception    @ExceptionHandler(SqlExceptionHelper.class)    @ResponseStatus(value = HttpStatus.CONFLICT)    public Map<String, String> handleConstraintViolationException(SqlExceptionHelper ex) {    // write your own logic to return user friendly response    }}
