为什么 JAXB 生成的类具有受保护的成员，我该如何更改? [英] Why do JAXB generated classes have protected members and how can I change this?

问题描述

我一直在互联网上搜索 JAXB 生成的类具有受保护成员的原因(所有这些成员，无论继承如何).

I have been searching the internet for a reason why JAXB generated classes have protected members (all of them, regardless of inheritance).

我希望成员是私人的.

我的搜索结果为空.

我有普通的 xsd 文件，它们使用 Maven 和 JAXB 转换为 Java 类.理想情况下，生成的成员应该是私有的，但我找不到实现这一点的方法.

I have normal xsd files which are converted into Java classes using Maven and JAXB. Ideally the generated members should be private but I cannot find a way to achieve this.

有没有办法修改这个默认行为?

Is there a way to modify this default behaviour?

推荐答案

好吧，我要回答我自己的问题.创建插件是正确的方法.

Well, I am going to respond to my own question. Creating a plugin was the right way to go.

我编写了以下插件，它似乎有效.

I wrote the following plugin and it seems to work.

public class PrivateMemberPlugin
    extends Plugin
{

    @Override
    public String getOptionName()
    {
        return "Xpm";
    }

    @Override
    public String getUsage()
    {
        return "  -Xpm    : Change members visibility to private";
    }

    @Override
    public boolean run(Outline model, Options opt, ErrorHandler errorHandler)
        throws SAXException
    {
        for (ClassOutline co : model.getClasses())
        {

            JDefinedClass jdc = co.implClass;
            // avoid concurrent modification by copying the fields in a new list
            List<JFieldVar> fields = new ArrayList<JFieldVar>(jdc.fields().values());
            for (JFieldVar field : fields)
            {
                // never do something with serialVersionUID if it exists.
                if (!field.name().equalsIgnoreCase("serialVersionuid"))
                {
                    // only try to change members that are not private
                    if (field.mods().getValue() != JMod.PRIVATE)
                    {
                        // since there is no way to change the visibilty, remove the field an recreate it
                        jdc.removeField(field);
                        jdc.field(JMod.PRIVATE, field.type(), field.name());

                    }
                }
            }

        }
        return true;
    }

}

如果你愿意，可以随意使用它.
