Java ApacheCamel:ValidatingProcessor:XSD验证

我正在尝试创建一个包并在ServiceMix中运行它。 我遇到了一个问题，非常感谢您的帮助

我想做的是： 从CXF端点生成SOAP消息，并使用Apache ServiceMix 5.0.0（Camel 2.12.3）根据XSD模式验证这些消息

我所做的： 实现了一个路由，该路由从CXF端点生成消息，然后对其进行验证

路由的

配置
方法：

private RouteBuilder getInputRoute() {

    SoapValidatingProcessor soapValidatingProcessor = new SoapValidatingProcessor();

    inputRoute = new RouteBuilder() {

      @Override
      public void configure() throws Exception {

        from(cxfEndpointInId())
          .convertBodyTo(java.lang.String.class, "UTF-8")
          .onException(org.apache.camel.ValidationException.class)
            .log(LoggingLevel.INFO, LOG_NAME, "Invalid message received!")
            .handled(true)
            .stop()
            .end()
          .bean(soapValidatingProcessor).id("SoapHeaderValidatingProcessor")
          .to("browse:foo")

}

已创建验证处理器：

public class SoapValidatingProcessor {

  private final String SCHEMA = "schema.xsd";  

  public SoapValidatingProcessor() {

    validatingProcessor = new ValidatingProcessor();
    validatingProcessor.setFailOnNullHeader(false);
    validatingProcessor.setFailOnNullBody(false);

  }

  @Handler
  public void validate(Exchange exchange) throws Exception {

    Resource validationSchema = context.getApplicationContext().getResource(SCHEMA);
    validatingProcessor.setSchemaUrl(validationSchema.getURL());
    validatingProcessor.loadSchema();

    /* Creating a new SchemaFactory instance */
    SchemaFactory xmlSchema = SchemaFactory
        .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);   

    validatingProcessor.setSchemaFactory(xmlSchema);    
    validatingProcessor.process(exchange);

  }

}

问题:
Apache Camel ValidatingProcessor[1]在多重威胁中表现不佳。我正在aprox发送SOAP消息。20毫秒的间隔，我得到以下异常。如果我将发送间隔增加到200ms以上，一切都很好

如果
validate
方法是
synchronized
，我就不会得到异常，但我不希望这样

我发现：
我在这里看到[2]这个错误已经解决了。我试图为每条消息创建一个新的SchemaFactory[3]实例，但仍然没有成功。你知道为什么我还是会出错吗？我做错了什么

谢谢
 您的代码不是线程安全的。在
SoapValidatingProcessor
中，您正在使用共享
validatingProcessor
，同时修改其状态/配置（每次加载不同的架构）

然而，在您的示例中，模式没有改变。在这种情况下，您应该只配置处理器一次（通过在启动时加载模式）

处理程序应仅调用不修改处理器状态的方法：

@Handler
public void validate(Exchange exchange) throws Exception {
    validatingProcessor.process(exchange);
}

在处理任何交换之前，应配置一次状态，例如：

public SoapValidatingProcessor(CamelContext context) {
    validatingProcessor = new ValidatingProcessor();
    validatingProcessor.setFailOnNullHeader(false);
    validatingProcessor.setFailOnNullBody(false);

    Resource validationSchema = context.getApplicationContext().getResource(SCHEMA);
    validatingProcessor.setSchemaUrl(validationSchema.getURL());
    validatingProcessor.loadSchema();

    /* Creating a new SchemaFactory instance */
    SchemaFactory xmlSchema = SchemaFactory
        .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);   

    validatingProcessor.setSchemaFactory(xmlSchema);    
}

事实上，删除
SoapValidatingProcessor
类并将所有
validatingProcessor
配置移动到
RouteBuilder.configure（）
方法中，然后直接在路由中使用
validatingProcessor
，可能会让您过得更好
