java - 如何在使用 com.sun.org.apache.xerces.internal.parsers.SAXParser 的 SAXBuilder 中禁用 XML 外部实体 (XEE) 处理

Question

这是我的片段:

public static SAXBuilder createBuilder(@NotNull final String schemaPath)  {


     final SAXBuilder builder = new SAXBuilder("com.sun.org.apache.xerces.internal.parsers.SAXParser", true);
    builder.setFeature("http://apache.org/xml/features/validation/schema", true);
    builder.setFeature("http://apache.org/xml/features/nonvalidating/load-external-dtd", false);


    builder.setFeature("http://apache.org/xml/features/disallow-doctype-decl",true);
    builder.setFeature("http://xml.org/sax/features/external-general-entities", false);
    builder.setFeature("http://xml.org/sax/features/external-parameter-entities", false);
    builder.setExpandEntities(false);
    builder.setProperty("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation", schemaPath);
    builder.setEntityResolver(getEntityResolver());
    return builder;
}

我花了一些时间寻找，但没有留下太多
