同事们，我正在尝试使用choice和doTry配置Camel路由。我的问题是第二个when子句上的Cannot resolve method 'when'。问题是：是否可以在choice子句中使用doTry构造？
路线如下所示：

public void configure() {
        from("sftp://.....").choice()
            .when(header("CamelFileName").contains("XML P")).log("Validate ${file:name}").bean(new MessProcessor(), "logInputMessDetails")
             .doTry().
                    to("validator:file:C:\\Users...\\xsds\\p.xsd").log("${file:name} is valid")
             .doCatch(ValidationException.class)
                 .log("XML P is not valid")
                 .to("file:sftp-inbound\\data-invalid\\" + header("CamelFileParent").toString())
                 .bean(messProcessor, "stopCamel")
/*The problem is here*/ .when(header("CamelFileName").contains("XML X")).log("Validate ${file:name}").bean(new MessProcessor(), "logInputMessDetails").
            doTry().to("validator:file:C:\\Users\....\xsds\\position.xsd").log("${file:name} is valid").
            doCatch(ValidationException.class).log("XML X is not valid").to("file:sftp-inbound\\data-invalid\\" + header("CamelFileParent").toString()).
            bean(messProcessor, "stopCamel")
            .end();

    }

• • 更新**

.bean(messProcessor, "stopCamel")删除后路由：

public void configure() {
        from("sftp://.....").choice()
            .when(header("CamelFileName").contains("XML P")).log("Validate ${file:name}").bean(new MessProcessor(), "logInputMessDetails")
             .doTry().
                    to("validator:file:C:\\Users...\\xsds\\p.xsd").log("${file:name} is valid")
             .doCatch(ValidationException.class)
                 .log("XML P is not valid")
                 .to("file:sftp-inbound\\data-invalid\\" + header("CamelFileParent").toString())
                 .end;
/*The problem is still here*/ .when(header("CamelFileName").contains("XML X")).log("Validate ${file:name}").bean(new MessProcessor(), "logInputMessDetails").
            doTry().to("validator:file:C:\\Users\....\xsds\\position.xsd").log("${file:name} is valid").
            doCatch(ValidationException.class).log("XML X is not valid").to("file:sftp-inbound\\data-invalid\\" + header("CamelFileParent").toString()).
            bean(messProcessor, "stopCamel")
            .end();

    }

• • 更新**还有一个变体

public void configure() {

        from("sftp:...}")

                .choice()
                .when(header("CamelFileName").contains("XML_POS")).log("Validate ${file:name}")
                .to("validator:file:C:\\pos.xsd").log("${file:name} valid")
                .when(header("CamelFileName").contains("XML_SETS")).log("Validate ${file:name}")
                 .to("validator:file:C:\\sets.xsd").log("${file:name} valid").end()
               .onException(Exception.class)
               .process(new FailureResponseProcessor())
               .handled(true);

            /*to("file:sftp-inbound");*/
    }
