本文探讨了使用JAXB从XML模式生成Java类时遇到的类名冲突问题。当模式文件包含特定元素时，如“xsd：schema”，会导致生成的Java类中出现重复的类名，例如“ComplexType”、“Attribute”等。文章提供了错误信息示例，并讨论了解决此类冲突的方法。

我使用jaxb从xml模式生成java类。

模式导入XMLSchema.xsd及其内容将用作文档中的元素。

如果我分别删除导入和引用“xsd：schema”，则绑定编译器会成功生成这些类。

如果我不这样做会产生以下错误，如果我尝试从XMLSchema.xsd生成Java类，这些错误是一样的！

-b xml_binding_test_3.xml
