如何使用gradle,jaxb和xjc从xsd生成jaxb类,类应该有XmlRootElement

我们尝试使用gradle,xsd和xjc生成JAXB类,而JAXB类应该具有XmlRootElement注释,因此它可以用于公开为Web服务响应.我们正在关注此链接http://azagorneanu.blogspot.com/2011/09/configure-maven-to-generate-classes.html,它有很大的帮助,但我们无法找到一个只有gradle的特定示例.所以我们想出了一些我们将分享的答案.

build.gradle应如下所示

    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

binding.xjb

下面的binding.xjb也可以使用

现在你可以运行任务' jaxb ',All set.干杯!
