如何使用JAXB从xsd生成实现可序列化接口的Java类?

xjc jaxb xsd java

Boris PavloviÄ · 技术社区 · 16 年前

我想将缓存引入到一个现有的Spring项目中,该项目使用JAXB来公开WebServices。缓存将在端点级别完成。为了实现这一点,使用JAXB从XSD生成的类需要实现 Serializable Object toString() 方法。

使用 xjc:serializable 在自定义绑定文件中添加 java.io.Serializable serialVersionUID

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
            xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
            xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
            xsi:schemaLocation="
http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
version="2.1">
  <globalBindings>
    <serializable uid="1" />
  </globalBindings>
</bindings>

toString()

使用超类(参见 xjc:superClass toString()

<?xml version="1.0" encoding="UTF-8"?>
<bindings xmlns="http://java.sun.com/xml/ns/jaxb"
                xmlns:xsi="http://www.w3.org/2000/10/XMLSchema-instance"
                xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc"
                xsi:schemaLocation="
http://java.sun.com/xml/ns/jaxb http://java.sun.com/xml/ns/jaxb/bindingschema_2_0.xsd"
    version="2.1">
    <globalBindings>
        <serializable uid="1" />
        <xjc:superClass name="the.package.to.my.XmlSuperClass" />
    </globalBindings>
</bindings>

这对我奏效了:

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jaxb:version="2.1">
    <jaxb:globalBindings>
        <xjc:serializable uid="1337"/>
    </jaxb:globalBindings>
</jaxb:bindings>

我使用这段代码,它为我工作

<?xml version="1.0" encoding="UTF-8"?>
<jaxb:bindings xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jaxb:version="2.1">
    <jaxb:globalBindings>
        <xjc:serializable uid="1"/><!--If you Forgot this line your class did not be serializable--!>
    </jaxb:globalBindings>
</jaxb:bindings>

为了获得接口可序列化,请将以下绑定信息添加到xsd文件中:

<?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:jaxb="http://java.sun.com/xml/ns/jaxb" jaxb:version="2.0" > <xs:annotation> <xs:appinfo> <jaxb:globalBindings optionalProperty="primitive"> <jaxb:serializable/> </jaxb:globalBindings> </xs:appinfo> </xs:annotation> <xs:element name="myXsdElement"> ..... </xs:element> </xs:schema>

这是一个使用CXF 3.1.10的示例。请记住包含编译组:“org.apache.cxf.xjc-utils”,名称:“cxf-xjc-runtime”,版本:“3.1.0”

<jxb:bindings 
xmlns:xs="http://www.w3.org/2001/XMLSchema"
xmlns:jxb="http://java.sun.com/xml/ns/jaxb"
version="2.1">

<jxb:bindings schemaLocation="META-INF/wsdl/xsd2.xsd">

        <jxb:globalBindings xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xs="http://www.w3.org/2001/XMLSchema">
