Examples with ProcessRouter io.seata.saga.proctrl.ProcessRouter used on opensource projects

Example 1 with ProcessRouter

use of io.seata.saga.proctrl.ProcessRouter in project seata by seata.

the class DefaultRouterHandler method route.

@Override
public void route(ProcessContext context) throws FrameworkException {
    try {
        ProcessType processType = matchProcessType(context);
        if (processType == null) {
            if (LOGGER.isWarnEnabled()) {
                LOGGER.warn("Process type not found, context= {}", context);
            }
            throw new FrameworkException(FrameworkErrorCode.ProcessTypeNotFound);
        }
        ProcessRouter processRouter = processRouters.get(processType.getCode());
        if (processRouter == null) {
            LOGGER.error("Cannot find process router by type {}, context = {}", processType.getCode(), context);
            throw new FrameworkException(FrameworkErrorCode.ProcessRouterNotFound);
        }
        Instruction instruction = processRouter.route(context);
        if (instruction == null) {
            LOGGER.info("route instruction is null, process end");
        } else {
            context.setInstruction(instruction);
            eventPublisher.publish(context);
        }
    } catch (FrameworkException e) {
        throw e;
    } catch (Exception ex) {
        throw new FrameworkException(ex, ex.getMessage(), FrameworkErrorCode.UnknownAppError);
    }
}

Example 2 with ProcessRouter

use of io.seata.saga.proctrl.ProcessRouter in project seata by seata.
