Schema优先设计

让我们从BCResponse的XML示例开始，为给定的元素创建XML Schema，然后JAXB可以使用其XJC编译器生成Java类。
Here是一个名为Publisher的Maven项目，使用标准的文件布局。该项目包括：

• BCResponse模型的XML架构文件Publisher-BCResponse.xsd
• Request模型的XML架构文件Publisher-Request.xsd
• 用于包配置的JAXB binding 文件Publisher.xjb
• JUnit测试类PublisherTest.java，用于验证（取消）编组
• 示例XML files和Publisher数据。
• 带有hisrc-higherjaxb-maven-plugin的Maven POM文件

Publisher
    src
        main
            java
            resources
                Publisher-BCResponse.xsd
                Publisher-Request.xsd
                Publisher.xjb
        test
            java
                com/models/PublisherTest.java
            resources
                simplelogger.properties
            samples
                BCResponse01.xml
                BCResponse02.xml
                Request01.xml
    pom.xml

download包含一个独立的Maven项目，可以使用以下命令执行：

mvn clean test

JAXB类由该插件使用该项目的pom.xml生成

<plugin>
    <groupId>org.patrodyne.jvnet</groupId>
    <artifactId>hisrc-higherjaxb-maven-plugin</artifactId>
    <version>${hisrc-higherjaxb-maven-plugin.version}</version>
    <executions>
        <execution>
            <goals>
                <goal>generate</goal>
            </goals>
        </execution>
    </executions>
</plugin>

并且被生成以：

target/generated-sources/xjc/

com
└── models
    ├── request
    │   ├── LegalEntity.java
    │   ├── ObjectFactory.java
    │   ├── package-info.java
    │   ├── PartyId.java
    │   └── Request.java

        ├── Content.java
        ├── ObjectFactory.java
        ├── Response.java
        └── ResponseStatus.java

方法

Publisher-BCResponse.xsd模式不声明名称空间，并配置为使用前缀"ns2" * 导入 * Publisher-Request.xsd模式。

xmlns:ns2="http://uri.abc.com/ML"
<xs:import namespace="http://uri.abc.com/ML" schemaLocation="Publisher-Request.xsd"/>

注意：前缀是任意的，可以是"abc"
Publisher-Request.xsd模式声明其命名空间，如下所示：

xmlns:tns="http://uri.abc.com/ML"
targetNamespace="http://uri.abc.com/ML"

Publisher.xjb绑定文件配置JAXB以生成类，如下所示：

<jaxb:package name="com.models.request"/>
<jaxb:package name="com.models.response"/>

测试

JUnit测试类PublisherTest.java扫描样本文件，并调用方法checkSample(File sample)将每个文件提供给测试人员。对于此项目，创建JAXBContext，并将samples路径中的每个文件 * 解组 * 为BCResponse对象或Request对象。成功后，每个对象都被 * 封送 * 用于日志记录和review。

Java First Design

在这种方法中，JAXB类是由您创建的，下面是它们的外观：

package-info.java

@jakarta.xml.bind.annotation.XmlSchema(namespace = "http://uri.abc.com/ML")
package com.models.request;

请求.java

package com.models.request;

import java.io.Serializable;
import jakarta.xml.bind.annotation.*;

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "", propOrder = { "legalEntity" })
@XmlRootElement(name = "Request")
public class Request implements Serializable
{
    private static final long serialVersionUID = 20230301L;

    @XmlElement(required = true)
    protected LegalEntity legalEntity;
    public LegalEntity getLegalEntity() { return legalEntity; }
    public void setLegalEntity(LegalEntity value) { this.legalEntity = value; }
}

LegalEntity.java

package com.models.request;

    private static final long serialVersionUID = 20230301L;

    @XmlElement(required = true)
    protected PartyId partyId;
    public PartyId getPartyId() { return partyId; }
    public void setPartyId(PartyId value) { this.partyId = value; }

    private static final long serialVersionUID = 20230301L;

    @XmlElement(required = true)

    public String getPublisher() { return publisher; }
    public void setPublisher(String value) { this.publisher = value; }

    private static final long serialVersionUID = 20230301L;
