java注解生成xml和包含CDATA问题

百度 java 生成 xml，有一大推的文章，主要的生成方式一种使用 Dom4J , 还有一种使用 Jdk 自带注解类！
下面主要整理我注解类的使用，（可以参考这篇文章Dom4J 生成 xml 和包含 CDATA 问题）和 xml 中 CDATA 问题的解决方法！
1: 要生成的 xml 原始文件！

<?xml version="1.0" encoding="utf-8"?>

2：xml 对应的 model 类！

        <span class="hljs-keyword">return</span> op.toString(<span class="hljs-string">"utf-8"</span>);  
    }  

}

setCDataElements 这里面你标注需 CDATA 的字段！

上面的这个例子可以直接拷贝运行，网上还一些其他的方法生成 xml 和 CDATA，如果你有好的方法，欢迎分享给我，谢谢！
