來， 開始要慢慢定位出問題的地方了。咱一步一步慢慢來
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，內容有點太多了， 就不貼出來了。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);
}
}
}沒錯，這邊就是我們最後要找到的地方。this.resource調用的文件配置裏面有錯誤，到裏面愉快的修改了問題既可解決
