如何使用gradle，jaxb和xjc从xsd生成jaxb类，这些类应具有XmlRootElement [英] How to generate jaxb classes from xsd using gradle, jaxb and xjc, classes should have XmlRootElement

问题描述

我们试图使用gradle，xsd和xjc生成JAXB类，并且JAXB类应具有XmlRootElement批注，以便可以将其用作Web服务响应.我们正在跟踪此链接 http://azagorneanu.blogspot.com/2011/09/configure-maven-to-generate-classes.html ，它起到了很大的作用，但我们找不到仅使用gradle的特定示例.因此，我们想出了一些可以分享的答案.

We were trying to generate JAXB classes using gradle, xsd and xjc, and JAXB classes should have XmlRootElement annotations so it could be used to expose as web service reponse. We were following this link http://azagorneanu.blogspot.com/2011/09/configure-maven-to-generate-classes.html, it helped in great deal but we were unable to find one particular example with gradle only. So we figured out few things what we will share as an answer.

推荐答案

build.gradle应该如下所示

build.gradle should look like below

    buildscript {
    repositories {
    mavenCentral()
        jcenter()
    }
    dependencies {
        classpath "net.saliman:gradle-cobertura-plugin:2.2.4"
        classpath 'com.github.jacobono:gradle-jaxb-plugin:1.3.5'

    }
}
apply plugin: 'com.github.jacobono.jaxb'
dependencies {
    jaxb 'com.sun.xml.bind:jaxb-xjc:2.2.7'
    jaxb "org.jvnet.jaxb2_commons:jaxb2-basics-ant:0.6.5"
    jaxb "org.jvnet.jaxb2_commons:jaxb2-basics:0.6.4"
    jaxb "org.jvnet.jaxb2_commons:jaxb2-basics-annotate:0.6.4"
}
configurations {
    jaxb
}
task jaxb(){
    description 'Converts xsds to classes'
    def jaxbTargetDir = file("generated")
    doLast {
    jaxbTargetDir.mkdirs()
    ant.taskdef(name: 'xjc', classname: 'org.jvnet.jaxb2_commons.xjc.XJC2Task', classpath: configurations.jaxb.asPath)
    ant.jaxbTargetDir = jaxbTargetDir 
    ant.xjc(destdir: '${jaxbTargetDir}', package: 'com.sample.jaxbclasses', schema:'generated/schema.xsd', binding:'generated/binding.xjb', extension:'true'){
        arg(value: "-Xannotate")
        }
    }
}

schema.xsd

schema.xsd

    <xs:element name="user" type="user" />
    <xs:element name="userList" type="userList" />

    <xs:complexType name="user">
        <xs:all>
            <xs:element name="id" type="xs:long" minOccurs="0" />
            <xs:element name="name" type="xs:string" />
            <xs:element name="registrationDate" type="xs:dateTime" />
        </xs:all>
    </xs:complexType>

    <xs:complexType name="userList">
        <xs:sequence>
            <xs:element name="user" type="user" minOccurs="0" maxOccurs="unbounded" />
        </xs:sequence>
    </xs:complexType>

</xs:schema>

binding.xjb

binding.xjb

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>

        <!-- Use java.util.Calendar instead of javax.xml.datatype.XMLGregorianCalendar for xs:dateTime -->
        <jaxb:javaType name="java.util.Calendar" xmlType="xs:dateTime"

                printMethod="javax.xml.bind.DatatypeConverter.printDateTime" />

        <!-- Force all classes implements Serializable -->
        <xjc:serializable uid="1" />
    </jaxb:globalBindings>

    <!-- Annotate the following classes with XmlRootElement -->
    <jaxb:bindings schemaLocation="schema.xsd" node="/xs:schema">
        <jaxb:bindings node="xs:complexType[@name='user']">
            <annox:annotate>
                <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="user" />
            </annox:annotate>
        </jaxb:bindings>
        <jaxb:bindings node="xs:complexType[@name='userList']">
            <annox:annotate>
                <annox:annotate annox:class="javax.xml.bind.annotation.XmlRootElement" name="userList" />
            </annox:annotate>
        </jaxb:bindings>
    </jaxb:bindings>
</jaxb:bindings>

binding.xjb下方也可以使用

below binding.xjb could be used as well

<?xml version="1.0"?>
<jxb:bindings version="1.0" xmlns:jxb="http://java.sun.com/xml/ns/jaxb" xmlns:xjc="http://java.sun.com/xml/ns/jaxb/xjc" jxb:extensionBindingPrefixes="xjc" xmlns:xs="http://www.w3.org/2001/XMLSchema">
  <jxb:bindings schemaLocation="schema.xsd" node="/xs:schema">
    <jxb:globalBindings>
      <xjc:simple />
    </jxb:globalBindings>
  </jxb:bindings>
</jxb:bindings>

现在，您可以运行" jaxb "(全部设置)任务. 干杯 ！

Now you can run the task 'jaxb', All set. Cheers!
