本文介绍了JAXB是否支持xsd:restriction?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

<xs:element name="age">
  <xs:simpleType>
    <xs:restriction base="xs:integer">
      <xs:minInclusive value="0"/>
      <xs:maxInclusive value="120"/>
    </xs:restriction>
  </xs:simpleType>
</xs:element>

所以我希望它转换为这样的Java代码:

So I want it to get converted to Java code like this:

public void setAge(int age){
    if(age < 0 || age > 120){
         //throw some exception
    }
     //setting the age as it is a valid value
}

是否可以在JAXB中使用?

Is it possible in JAXB?

看到一些WebService Client存根生成器执行此操作可能是axis2 webservice但不确定。

Had seen some WebService Client stub generator doing this maybe axis2 webservice but not sure.

推荐答案

JAXB(JSR-222) 规范不包括在域模型中生成失败的快速逻辑。现在通常的做法是以注释(或XML)的形式表示验证规则并对它们运行验证。 Bean验证(JSR-303) 将此标准化可用于任何Java EE 6实现。

The JAXB (JSR-222) specification does not cover generating fail fast logic into the domain model. A common practice now is to express validation rules in the form of annotations (or XML) and run validation on them. Bean Validation (JSR-303) standardizes this and is available in any Java EE 6 implementation.

XJC扩展

我有我自己没有尝试过以下扩展,但似乎它会生成 Bean验证(JSR) -303) 来自XML模式的域模型表示验证规则的注释。由于XJC非常易于扩展,因此可能还有其他插件可供使用。

I have not tried the following extension myself but it appears as though it will generate Bean Validation (JSR-303) annotations onto the domain model representation validation rules from the XML schema. As XJC is very extensible there may be other plug-ins available as well.
