Spring框架提供了多种方式来捕获和处理ServletException。
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(ServletException.class)
public ResponseEntity<String> handleServletException(ServletException ex) {
// 处理ServletException异常
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("处理ServletException异常");
}
}
@Controller
public class MyController {
@ExceptionHandler(ServletException.class)
public ResponseEntity<String> handleServletException(ServletException ex) {
// 处理ServletException异常
return ResponseEntity.status(HttpStatus.INTERNAL_SERVER_ERROR).body("处理ServletException异常");
}
// 其他方法...
}
public class MyHandlerExceptionResolver implements HandlerExceptionResolver {
@Override
public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
if (ex instanceof ServletException) {
// 处理ServletException异常
return new ModelAndView("error", "message", "处理ServletException异常");
}
return null;
}
}
以上是Spring框架中捕获和处理ServletException的几种常用方式。在实际应用中,可以根据具体需求选择合适的方式进行异常处理。
