## Override the default exception handlers { #override-the-default-exception-handlers }

**FastAPI** has some default exception handlers.

These handlers are in charge of returning the default JSON responses when you `raise` an `HTTPException` and when the request has invalid data.

You can override these exception handlers with your own.

        // Clear the protocol handlers cache
        Field handlersField = Handler.class.getDeclaredField("PROTOCOL_HANDLERS");
        handlersField.setAccessible(true);
        @SuppressWarnings("unchecked")
        Map<String, URLStreamHandler> handlers = (Map<String, URLStreamHandler>) handlersField.get(null);
        handlers.clear();
    }

    /**
     * Pre-populates the protocol handlers cache with mock handlers for testing.

and other connections will be blocked while the large payload is being sent.

## Handlers & Routes

Handlers have a predefined Handler ID.
In addition, there can be several *static* subroutes used to differentiate between different handlers of the same ID.
A subroute on a client must match a subroute on the server. So routes cannot be used for dynamic routing, unlike HTTP.

        if (logger.isDebugEnabled()) {
            logger.debug("Loaded CorsHandler: origin={}", origin);
        }
        handerMap.put(origin, handler);
    }

    /**
     * Gets the CORS handler for the specified origin.
     * If no specific handler is found, returns the wildcard handler.
     *
     * @param origin the origin to look up
     * @return the CORS handler for the origin, or null if none found
     */

    }

    @Override
    public void addHandlers(Map<String, ArtifactHandler> handlers) {
        throw new UnsupportedOperationException("Adding handlers programmatically is not supported anymore");
    }

    @Deprecated
    public Set<String> getHandlerTypes() {
        throw new UnsupportedOperationException("Querying handlers programmatically is not supported anymore");
    }

		if m.handlers.hasAny(id) && !id.isTestHandler() {
			return ErrHandlerAlreadyExists
		}
		m.handlers.streams[id] = &h
		return nil
	}
	subID := makeSubHandlerID(id, h.Subroute)
	if m.handlers.hasSubhandler(subID) && !id.isTestHandler() {
		return ErrHandlerAlreadyExists
	}
	m.handlers.subStreams[subID] = &h
	// Copy so clients can also pick it up for other subpaths.
	m.handlers.subStreams[makeZeroSubHandlerID(id)] = &h

In this case, the `startup` event handler function will initialize the items "database" (just a `dict`) with some values.

You can add more than one event handler function.

And your application won't start receiving requests until all the `startup` event handlers have completed.
