使用jaxb的spring 4 restful service - post方法错误地绑定输入数据

标签： java spring rest model-view-controller jaxb

我正在尝试创建基于Spring 4的restful服务。该服务应该使用json和xml。我创建了一个xsd并使用xjc将xsd编译为绑定类。

这是xsd 

<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" elementFormDefault="qualified" attributeFormDefault="qualified">
    <xsd:element name="ServicesRequest">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="activityType" type="xsd:int"/>
                <xsd:element ref="ServicesInput" minOccurs="0" maxOccurs="unbounded"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
    <xsd:element name="ServicesInput">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="name" type="xsd:string" minOccurs="0"/>
                <xsd:element ref="ListOfValues" minOccurs="0"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
    <xsd:element name="ListOfValues">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element name="Value" type="xsd:string" minOccurs="0" maxOccurs="unbounded"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>

以下是运行xjc之后的java类：

这些是罐子

  1. commons-logging.jar jackson-annotations.jar jackson-core.jar jackson-databind.jar jackson-dataformat-xml.jar jackson-dataformat-yaml.jar jackson-datatype-joda.jar jackson-jaxrs-base.jar jackson-jaxrs-json-provider.jar jackson-module-jaxb-annotations.jar jaxb-api.jar jaxb-core.jar jaxb-impl.jar jaxb-jxc.jar jaxb-xjc.jar log4j.jar spring-aop.jar spring-aspects.jar spring-beans.jar spring-bridge.jar spring-context-support.jar spring-context.jar spring-core.jar spring-expression.jar spring-jdbc.jar spring-jms.jar spring-messaging.jar spring-oxm.jar spring-tx.jar spring-web.jar spring-webmvc.jar spring-ws-core.jar spring-ws-support.jar spring-xml.jar stax-api.jar stax-ex.jar stax2-api.jar streambuffer.jar

    2. 所以我的问题是，上面列出的输入为什么我在控制器中看不到相同的内容。输入确认到xsd。

    非常感谢所有的帮助。

1 个答案:

答案 0 :(得分：0)

我不得不从类路径中删除Jackson-dataformat-xml.jar。然后它开始使用jaxb绑定并开始正确绑定。
