用SpringBoot做一个简易前台页面，其中左侧的菜单是fsLayui的实现的，需要对它进行国际化。方案就是后台定一个接口，返回json的配置信息，加上菜单配置项。但是菜单的字符串太长了，如果使用拼接的方式书写很麻烦，所以想到定义一个模板数据，使用正则表达式去匹配并替换对应的数据。
如何实现
java.util.regex.Matcher提供了两个方法appendReplacement和appendTail，用来通过StringBuffer来替换和拼接替换以后的字符串。
示例java代码
final String menuTemplate = "{\n" +
" \"errorNo\":0,\n" +
" \"results\":\n" +
" {\n" +
" \"data\":\n" +
" [\n" +
"\t\t{\"menuId\":\"1\",\"menuName\":\"##menu.console##\",\"menuIcon\":\"fa-cog\",\"menuHref\":\"\",\"parentMenuId\":\"0\"},\n" +
