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
