如何从引用不同包中的枚举的JAXB对象生成模式?
以下是一个例子:
枚举等级
package com.example.one
public enum EnumExample {
VALUE_ONE
VALUE_TWO
}
JAXB Class
package com.example.two
public class Example {
private EnumExample enumExample;
@XMLElement(name="enumExample", required=true)
public EnumExample getEnumExample() {
return enumExample
}
public void setEnumExample() {
this.enumExample = enumExample;
}
}
package-info.java
@javax.xml.bind.annotation.XmlSchema(namespace = "http://example.com", elementFormDefault = javax.xml.bind.annotation.XmlNsForm.QUALIFIED)
package com.example.two;
Ant Target
<path id="glassfish.schemagen.classpath">
<pathelement location="/apps/glassfish/lib/webservices-tools.jar" />
</path>
<taskdef name="schemagen" classname="com.sun.tools.jxc.SchemaGenTask">
<classpath refid="glassfish.schemagen.classpath" />
</taskdef>
<schemagen srcdir="${src.dir}/com/example/two" destdir="xsd">
<schema namespace="http://exmaple.com" file="example.xsd" />
</schemagen>
当我运行上面的例子时,我得到以下内容:

我知道它导致错误的枚举因为如果我切换到一个字符串就会消失。如何使用上面的示例生成一个模式,其中枚举位于同一名称空间或不同的名称空间中?
答案 0 :(得分:0)
定义的大部分属性
您是否尝试过使用包含或排除元素(未经测试)?
<schemagen srcdir="${src.dir}/com/example" destdir="xsd">
<schema namespace="http://exmaple.com" file="example.xsd" />
<include name="one/EnumExample.java"/>
<include name="two/Example.java"/>
</schemagen>
