IllegalAnnotationExceptions包$Class的java xx计数是一个非静态内部类，JAXB无法处理这些

Question

您好，我有Java Bean-like blow，我需要用它创建xml文件，但运行程序时出错，请说：

mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Template$Random is a non-static inner class, and JAXB can't handle those.
    this problem is related to the following location:
        at mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Template$Random
        at public mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Template$Random mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Template.getRandom()
        at mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Template
        at public mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Template mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Category.getTemplate()
        at mehritco.ir.megnatis.ejb.nlp.aiml.Aiml$Category

JavaBean：

package mehritco.ir.megnatis.ejb.nlp.aiml;

import java.util.ArrayList;
import java.util.List;

import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name = "aiml")
public class Aiml {
    List<Category> categories = new ArrayList<Category>();
    
    public List<Category> getCategories() {
        return categories;
    }
    @XmlElement
    public void setCategories(List<Category> categories) {
        this.categories = categories;
    }

    
    @XmlRootElement(name = "category")
    public class Category<T>{
        Pattern pattern ;
        Template<T> template ;
        public Pattern getPattern() {
            return pattern;
        }
        @XmlElement
        public void setPattern(Pattern pattern) {
            this.pattern = pattern;
        }
        public Template getTemplate() {
            return template;
        }
        @XmlElement
        public void setTemplate(Template template) {
            this.template = template;
        }
        
        
        
        
    }
    @XmlRootElement(name = "pattern")
    public class Pattern{
        String pattern;

        public String getPattern() {
            return pattern;
        }
        @XmlElement
        public void setPattern(String pattern) {
            this.pattern = pattern;
        }
        
    }
    @XmlRootElement(name = "template")
    public class Template<T>{
        Random random;
        String template;

        public Random getRandom() {
            return random;
        }

        public void setRandom(Random random) {
            this.random = random;
        }


        public String getTemplate() {
            return template;
        }

        public void setTemplate(String template) {
            this.template = template;
        }




        @XmlRootElement(name = "random")
        public class Random {
            List<String> li = new ArrayList<String>();

            public List<String> getLi() {
                return li;
            }
            @XmlElement(name = "li")
            public void setLi(List<String> li) {
                this.li = li;
            }

        }
        
        
        
    }
    
    
    
    
}

主要方法是：

        Aiml aiml = new Aiml();

        List<Aiml.Category> listCategory = new ArrayList<Aiml.Category>();
        Aiml.Category category =   aiml.new Category();
        
        Aiml.Pattern pattern = aiml.new Pattern();
        pattern.setPattern("Hello");
        category.setPattern(pattern);
        
        Aiml.Template<Aiml.Template.Random> template = aiml.new Template<Aiml.Template.Random>();
        Aiml.Template.Random random = template.new Random();
        List<String> list = random.getLi();
        list.add("hi");
        list.add("hello");
        random.setLi(list);
        template.setRandom(random);
        category.setTemplate(template);
        
        listCategory.add(category);
        aiml.setCategories(listCategory);
        
        

          try {

            File file = new File("D:\\TestFile\\file.xml");
            JAXBContext jaxbContext = JAXBContext.newInstance(Aiml.class);
            Marshaller jaxbMarshaller = jaxbContext.createMarshaller();

            // output pretty printed
            jaxbMarshaller.setProperty(Marshaller.JAXB_FORMATTED_OUTPUT, true);

            jaxbMarshaller.marshal(aiml, file);
            jaxbMarshaller.marshal(aiml, System.out);

          } catch (JAXBException e) {
            e.printStackTrace();
          }
        

我需要创建java类来创建aiml对象，以便保存，读取我创建的对象，但在创建的这个类型类中无法完成，使用JAXB有什么问题？ the xml format I'm need to create is here以及其他一些可能发生的情况，如：

<category>
    <pattern>ONCE I *</pattern>
    <template>
        <random>
            <li>Go on.</li>
            <li>Can you be more specific?</li>
            <li>I did not know that.</li>
            <li>Are you telling the truth?</li>
            <li>I don't know what that means.</li>
            <li>Try to tell me that another way.</li>
            <li>What is it?</li>
        </random>
    </template>
</category>

现在我需要知道这里有什么例外，必须做什么
