使用Apache Camel针对XSD验证XML

Question

我的目标是读取CSV文件，将其转换为XML，并根据XSD对其进行验证。代码如下：

    CamelContext _ctx = new DefaultCamelContext(); 
    _ctx.addRoutes(new RouteBuilder() {

        public void configure() throws Exception {
            from("file:src/main/resources?fileName=data-sample.csv")
            .process(new MyTransformValidator())
            .to("file:src/main/resources/?fileName=emp.xml")
            .to("validator:src/main/resources?fileName=SampleXMLStructure.xsd");                
        }
});

错误：

线程“main”组织中出现异常。阿帕奇。骆驼FailedToCreateRouteException:无法在以下位置创建路由1：

此外，我还想配置如果XML对给定的XSD无效，是否会发生异常。我们如何配置它？

请好心帮忙。

对于异常块，请尝试以下操作：

from("file:src/main/resources?fileName=data-sample.csv")
            .process(new MyTransformValidator())
            .to("file:src/main/resources/?fileName=emp.xml")
            .doTry()
            .to("validator:file:src/main/resources/SampleXMLStructure.xsd")
            .doCatch(Exception.class)
            .log(LoggingLevel.WARN, "Failed validation cause:${exchangeProperty.CamelExceptionCaught}")
            .process(exchange -> {
                Throwable exception = exchange.getProperty(Exchange.EXCEPTION_CAUGHT, Throwable.class);
                // process exception
            })
            .end()
            .log(LoggingLevel.INFO, "Finished processing file");
