问题:发送和接收数据

[英]Problems: Sending and Receiving Data

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。 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);
     }

我想有了代码,我的问题就会变得更加清楚。

尝试将Syncronized添加到您的方法中

我遇到了很多麻烦,因为接收器试图读取未完成的内容

javadoc中的更多信息: https : //docs.oracle.com/javase/tutorial/essential/concurrency/syncmeth.html

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

谢谢maquina,

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);
     }
