In the LiteFlow component, if an exception is thrown out, the chain will be interrupted. Except for setting the ignoreError keyword in Parallel mode.

Outgoing exceptions are caught by the executor and wrapped in a LiteflowResponse object.

You can get exceptions in the LiteflowResponse object using the following methods

LiteflowResponse response = flowExecutor.execute2Resp("chain1", initial parameters, CustomContext.class);
if (!response.isSuccess()){
  Exception e = response.getCause();
}

If your business needs to obtain the exception code, your custom exception needs to implement the LiteFlowException interface provided by LiteFlow:

public class YourException extends LiteFlowException {
	public YourException(String code, String message) {
		super(code, message);
	}
}

If your business throws an exception that implements the LiteFlowException interface, you can get the message and code information in the LiteflowResponse:

LiteflowResponse response = flowExecutor.execute2Resp("chain1", 初始参数, CustomContext.class);
if (!response.isSuccess()){
  Exception e = response.getCause();
  String code = response.getCode();
  String message = response.getMessage();
}

tip

If your exception does not implement LiteFlowException, the code and message fields are both null.
