使用Jaxb KieservicesClient创建XML失败(Kie 6.5.0)



我有一个这样的对象:

@XmlRootElement(name="com.Operation")
@XmlAccessorType(XmlAccessType.FIELD)
public class Operation implements java.io.Serializable
{
   static final long serialVersionUID = 1L;
   @org.kie.api.definition.type.Label("systemCode")
   @XmlElement
   private int systemCode;
   [...]

当我手动用以下代码手动查找此词时,它似乎运行良好:

[...]
JAXBContext jaxbContext = 
DroolsJaxbHelperProviderImpl.createDroolsJaxbContext(classNames, null);
Marshaller marshaller = jaxbContext.createMarshaller(); 
StringWriter xml = new StringWriter(); 
marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true); 
marshaller.marshal(object, System.out);

因此,控制台打印:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
    <com.Operation>
    <systemCode>1</systemCode>
    [...]

但是,当我使用kieserverclient鼓励代码时,我会遇到错误:

org.kie.server.client.KieServicesException: Error while serializing request data!
at org.kie.server.client.impl.AbstractKieServicesClientImpl.serialize(AbstractKieServicesClientImpl.java:514)
at org.kie.server.client.impl.AbstractKieServicesClientImpl.makeHttpPostRequestAndCreateServiceResponse(AbstractKieServicesClientImpl.java:234)
at org.kie.server.client.impl.RuleServicesClientImpl.executeCommandsWithResults(RuleServicesClientImpl.java:72)
[...]
Caused by: javax.xml.bind.MarshalException
- with linked exception:
[com.sun.istack.SAXException2: class com.Operation ni ninguna de sus superclases se conocen en este contexto.

(IS是西班牙语,但我猜该错误很容易翻译)

我用于kieserverclient的jaxb的代码片段:

KieCommands commandsFactory = KieServices.Factory.get().getCommands();
List<Command<?>> cmds = new ArrayList<Command<?>>();
BatchExecutionCommand command = commandsFactory.newBatchExecution(cmds, SESSION_STATEFUL);
Command<?> insertObjectCommand = null;
insertObjectCommand = commandsFactory.newInsert(operation, operation.getClass().getName(), false, null); 
cmds.add(insertObjectCommand);
[...]
KieServicesConfiguration config =  KieServicesFactory.newRestConfiguration(KieServer.urlKieServer,
                        KieServer.name,
                        KieServer.password);
config.setMarshallingFormat(MarshallingFormat.JAXB); 
KieServicesClient client = KieServicesFactory.newKieServicesClient(config);
RuleServicesClient rulesClient = client.getServicesClient(RuleServicesClient.class);  
ServiceResponse<ExecutionResults> response = rulesClient.executeCommandsWithResults("instances/"+containerName, command); 

关于我做错了什么的想法,以及为什么一个编组有效,而另一个编组不行?

除了POJO,我目前没有Maven的项目,因为我想知道我实际上需要哪些罐子才能使这些项目有效,并且在Maven的情况下,许多依赖项会自动解决,而且我基本上不知道我的知道需要(我的.m2满是我不知道的下载罐子)。解决后,我将把项目转换为Maven。

涉及的库是:

  • droolsjbpm-integration-distribution-6.5.0.final
  • droolsjbpm-tools-distribution-6.5.0.final
  • httpclient-4.5.3
  • httpcore-4.4.6
  • javax.ws.rs-api2.0
  • jaxb-xjc-2.3.0
  • JMS-1.1
  • kie-remote-client-6.5.0.final
  • kie-remote-common-6.5.0.final
  • kie-remote-jaxb-6.5.0.final
  • kie-server-api-6.5.0.final
  • kie-server-client-6.5.0.final
  • optaplanner-core-6.5.0.final

环境: -JBOSS开发人员Studio 10.4 -Wildfly 10.1 -JDK 1.8

ps:我已经能够通过休息连接到Kieserver,但这是与灰心丧气的代码相关的,可能是因为(我想没有人回答过我),我没有得到我想要的响应。<<<<<<<<<<

所以我得到了答案,这要归功于我在redhat网页上遇到的一些准则:使用Kie Server Java Client api

触发规则在这种情况下,

密钥是将类添加到KIE客户端的配置选项中。下面的代码对于使用Drools/Kie Workbench 6.5.0时与Kie服务器连接有效。命令是有效的batchexecutionCommand:

KieServicesConfiguration config =  KieServicesFactory.
                newRestConfiguration(KieServer.urlKieServer,
                        KieServer.name,
                        KieServer.password);
config.setMarshallingFormat(MarshallingFormat.JAXB); 
config.setTimeout(3000L); //optional
Set<Class<?>> allClasses = new HashSet<Class<?>>();
allClasses.add(YOURCLASS.class);
config.addExtraClasses(allClasses);
KieServicesClient client = KieServicesFactory.newKieServicesClient(config);
RuleServicesClient rulesClient = client.getServicesClient(RuleServicesClient.class);  
ServiceResponse<ExecutionResults> response = rulesClient.executeCommandsWithResults(containerName, command); 

希望它对某人有帮助。
