如何解决Camel Jaxb解扰问题 [英] How to fix Camel Jaxb unmasharlling problem

问题描述

我创建了一个xsd，并将其与如下所示的jaxb插件一起使用：

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
           xmlns="http://www.mycompany.fr/Canonical/Schema/invoices.xsd"
           targetNamespace="http://www.mycompany.fr/Canonical/Schema/invoices.xsd"
           elementFormDefault="qualified"
           attributeFormDefault="unqualified">

    <xs:element name="invoices">
        <xs:complexType>
            <xs:sequence>
                <xs:element name="invoice" maxOccurs="unbounded" minOccurs="0">
                    <xs:complexType>
                        <xs:sequence>
                            <xs:element minOccurs="0" name="invoice-type" type="xs:string"/>
                            <xs:element minOccurs="0" name="insertion-date" type="xs:dateTime"/>
                            <xs:element minOccurs="0" name="amount" type="xs:double"/>
                        </xs:sequence>
                        <xs:attribute name="invoice-number" type="xs:string" use="required"/>
                    </xs:complexType>
                </xs:element>
            </xs:sequence>
        </xs:complexType>
    </xs:element>
</xs:schema>

插件：

<plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>jaxb2-maven-plugin</artifactId>
                <version>2.5.0</version>
                <executions>

                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <packageName>com.mycompany.model</packageName>
                    <sources>
                        <source>src/main/resources/xsd/invoices.xsd</source>
                    </sources>
                </configuration>
            </plugin>

它为我生成了这个类：

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = {
    "invoice"
})
@XmlRootElement(name = "invoices")
public class Invoices {

    protected List<Invoice> invoice;

    /**
     * Gets the value of the invoice property.
     * 
     * <p>
     * This accessor method returns a reference to the live list,
     * not a snapshot. Therefore any modification you make to the
     * returned list will be present inside the JAXB object.
     * This is why there is not a <CODE>set</CODE> method for the invoice property.
     * 
     * <p>
     * For example, to add a new item, do as follows:

     * <p>
     * Objects of the following type(s) are allowed in the list
     * {@link Invoice }
     * 
     *

    public List<Invoice> getInvoice() {
        if (invoice == null) {
            invoice = new ArrayList<Invoice>();
        }
        return this.invoice;
    }

我使用此骆驼路由对XML进行解混：

    JaxbDataFormat jaxbDataFormat = new JaxbDataFormat();
        jaxbDataFormat.setSchema("classpath:xsd/invoices.xsd");
from("file:{{xml.location}}?delay=1000")
                .log("Reading invoice XML data from ${header.CamelFileName}")
                .unmarshal(jaxbDataFormat)
                .split(body())
            .to("direct:processedXml");

但是当我运行我的应用程序时，我收到以下错误...

[route2][unmarshal1] [unmarshal[org.apache.camel.model.dataformat.JaxbDataFormat@7aff8796] ][0]
