XStream包混疊

包裝混疊用于創(chuàng)建一個(gè)類XML的完全限定名稱的別名到一個(gè)新的限定名稱。再次修改我們的例子中并更改以下代碼。

xstream.alias("student", Student.class);
xstream.alias("note", Note.class);

xstream.aliasPackage("my.company.xstream", "com.yiibai.xstream");

讓我們使用XStream測(cè)試上述對(duì)象序列化。

創(chuàng)建一個(gè)Java類名為 XStreamTester 文件在 C:\>XStream_WORKSPACE\com\yiibai\xstream.
