外部DTD:无法读取外部DTD 'mybatis-3-mapper.dtd'，因为Quarkus本机不允许'http‘访问

Question

我正在尝试在构建于docker本地模式的Quarkus项目中使用mybatis。加载xml映射文件时，会引发以下错误：

org.apache.ibatis.builder.BuilderException: Error creating document instance.  Cause: org.xml.sax.SAXParseException; lineNumber: 2; columnNumber: 108; External DTD: Failed to read external DTD 'mybatis-3 -mapper.dtd', because 'http' access is not allowed due to restriction set by the accessExternalDTD property.
  at org.apache.ibatis.parsing.XPathParser.createDocument(XPathParser.java:263)                                                                                                                               
  at org.apache.ibatis.parsing.XPathParser.(XPathParser.java:127)                                                                                                                                       
  at org.apache.ibatis.builder.xml.XMLMapperBuilder.(XMLMapperBuilder.java:81)

我用来加载映射文件的代码片段是：

Configuration configuration = new Configuration();
String mapperResourceName = "mybatis/test.xml";
InputStream inputStream = Thread.currentThread().getContextClassLoader().getResourceAsStream(mapperResourceName);
XMLMapperBuilder mapperParser = new XMLMapperBuilder(inputStream, configuration, mapperResourceName,
                        configuration.getSqlFragments());
mapperParser.parse();
MappedStatement  mappedStatement = configuration.getMappedStatement("test");
BoundSql boundSql = mappedStatement.getBoundSql(params);

而映射器文件是：

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="Test">
    <select id="test" >
        SELECT t
        FROM Test t
    </select>
</mapper>

我已经尝试添加了

<quarkus.native.additional-build-args>-J-Djavax.xml.accessExternalDTD=all</quarkus.native.additional-build-args>

没有成功。

我已经找到了解决问题的方法:在Dockerfile.native文件中，必须在应用程序启动时添加-Djavax.xml.accessExternalDTD=all。
