can anybody tell me how to set encoding="ISO-8859-1" and instead of
XMLInputFactory xmlInFactory = XMLInputFactory.newFactory();
i have used
XMLInputFactory xmlInFactory = XMLInputFactory.newInstance();

Answer 1

在编组器上，设置编码的属性。

m.setEncoding("jaxb.encoding", "ISO-8859-1");

Answer 2

创建文档时，您传入要使用的编码。

xmlEventFactory.createStartDocument("ISO-8859-1");
