Q1: 用java代码怎么给word中的文字加链接 代码该怎么写
建议可以用第三方，你参考下spire.doc for java的超链接设置方法，代码方案：Java 添加超链接到Word文档，包括了给文字添加链接，给图片添加链接，添加网页链接、邮箱链接、文档链接不同类型的链接。
Q2: java 的超链接代码 怎么写啊
a href="your target url"Link/a
如果在servlet中：
PrintWriter out = res.getWriter();
out.println("a href='your target url'Link/a");
如果是连接自己项目中的，请注意相对路径的写法。建议加上context path.
