[英]Problems: Sending and Receiving Data
I am trying to perform two processes using bean, my problem is that I can not find the way these processes are performed continuously. 我正在尝试使用bean执行两个过程,但是我的问题是我找不到连续执行这些过程的方式。 The first process is to send an object and the second process is the response of the object. 第一个过程是发送对象,第二个过程是对象的响应。
@Component
public class Proceso implements InitializingBean{
private static final String XML_SCHEMA_LOCATION = "/proceso/model/schema/proceso.xsd";
private Envio envio;
private Respuesta respuesta;
public void Proceso_envio(Proceso proceso, OutputStream outputstream) throws JAXBException{
envio.marshal(proceso, outputstream);}
public void Proceso_respuesta(InputStream inputstream) throws JAXBException, FileNotFoundException{
Object obj = unmarshaller.unmarshal(inputStream);
return (Proceso_respuesta) obj;}
@Override
public void afterPropertiesSet() throws Exception{
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(getClass().getResource(XML_SCHEMA_LOCATION));
JAXBContext jc = JAXBContext.newInstance(Envio.class, Respuesta.class);
this.marshaller = jc.createMarshaller();
this.marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
this.marshaller.setProperty(Marshaller.JAXB_ENCODING, StandardCharsets.UTF_8.displayName());
this.marshaller.setSchema(schema);
this.unmarshaller = jc.createUnmarshaller();
this.unmarshaller.setSchema(schema);
}
I imagine that with the code my question becomes clearer. 我想有了代码,我的问题就会变得更加清楚。
try to add Syncronized to your methods 尝试将Syncronized添加到您的方法中
i had this trouble many times because the receiver was trying to read something that is not finished 我遇到了很多麻烦,因为接收器试图读取未完成的内容
More info in the javadoc: https://docs.oracle.com/javase/tutorial/essential/concurrency/syncmeth.html javadoc中的更多信息: https : //docs.oracle.com/javase/tutorial/essential/concurrency/syncmeth.html
when you add this key word to the methods this will wait to the other until it insnt finished 当您将此关键字添加到方法中时,它将等待另一个,直到它完成
thanks maquina, 谢谢maquina,
this is the solution: 这是解决方案:
@Component
public class Proceso implements InitializingBean{
private static final String XML_SCHEMA_LOCATION = "/proceso/model/schema/proceso.xsd";
private Envio envio;
private Respuesta respuesta;
public synchronized void Proceso_envio(Proceso proceso, OutputStream outputstream) throws JAXBException{
envio.marshal(proceso, outputstream);}
public void synchronized Proceso_respuesta(InputStream inputstream) throws JAXBException, FileNotFoundException{
Object obj = unmarshaller.unmarshal(inputStream);
return (Proceso_respuesta) obj;}
@Override
public void afterPropertiesSet() throws Exception{
SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema = schemaFactory.newSchema(getClass().getResource(XML_SCHEMA_LOCATION));
JAXBContext jc = JAXBContext.newInstance(Envio.class, Respuesta.class);
this.marshaller = jc.createMarshaller();
this.marshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);
this.marshaller.setProperty(Marshaller.JAXB_ENCODING, StandardCharsets.UTF_8.displayName());
this.marshaller.setSchema(schema);
this.unmarshaller = jc.createUnmarshaller();
this.unmarshaller.setSchema(schema);
}
