来， 开始要慢慢定位出问题的地方了。咱一步一步慢慢来

public class DefaultFlowHolder implements FlowDefinitionHolder {
private void assembleFlow() throws FlowDefinitionConstructionException {
        try {
            this.assembling = true;
>             this.flowDefinition = this.assembler.assembleFlow();
        } catch (FlowBuilderException var5) {
            throw new FlowDefinitionConstructionException(this.assembler.getFlowBuilderContext().getFlowId(), var5);
        } finally {
            this.assembling = false;
        }

    }
}

public class FlowAssembler {
        public Flow assembleFlow() throws FlowBuilderException {
                    Flow var2;
                    try {
    >             this.flowBuilder.init(this.flowBuilderContext);
                            this.directAssembly();
                            var2 = this.flowBuilder.getFlow();
                    } finally {
                            this.flowBuilder.dispose();
                    }

                    return var2;
    }
}

public abstract class AbstractFlowBuilder implements FlowBuilder {
        public void init(FlowBuilderContext context) throws FlowBuilderException {
                        this.context = context;
                        this.doInit();
>                       this.flow = this.createFlow();
    }
}

public abstract class AbstractFlowBuilder implements FlowBuilder {
        protected Flow createFlow() {
                    String id = this.getContext().getFlowId();
                    AttributeMap attributes = this.getContext().getFlowAttributes();
                    return this.getContext().getFlowArtifactFactory().createFlow(id, attributes);
            }
}

哎呀，内容有点太多了， 就不贴出来了。直至找到

public class XmlFlowModelBuilder implements FlowModelBuilder {
    public void init() throws FlowModelBuilderException {
                    try {
>                           this.document = this.documentLoader.loadDocument(this.resource);
                            this.initLastModifiedTimestamp();
                    } catch (IOException var2) {
                            throw new FlowModelBuilderException("Could not access the XML flow definition at " + this.resource, var2);
                    } catch (ParserConfigurationException var3) {
                            throw new FlowModelBuilderException("Could not configure the parser to parse the XML flow definition at " + this.resource, var3);
                    } catch (SAXException var4) {
                            throw new FlowModelBuilderException("Could not parse the XML flow definition document at " + this.resource, var4);
                    }
            }
        }

没错，这边就是我们最后要找到的地方。this.resource调用的文件配置里面有错误，到里面愉快的修改了问题既可解决
