如何将Java变量传递给HTML标记？

Question

我有一个包含网址的变量。

String url = getEnvironment().getProperty(CUSTOMER_SIGN_IN_PAGE_URL);

那么我该如何使用这个url变量作为以下代码段的url

String customerMessage = new StringBuilder("Hi, We have received your request. Your account will be unblocked within 48 hours.")
     .append("<br><br><a href=\" url \" target=\"_blank\"><button> CONTINUE </button></a>")
     .toString();

Answer 1

你需要用第二个“转义你的字符串”并用+连接它

EG

     String customerMessage = new StringBuilder("Hi, We have received your request. Your account will be unblocked within 48 hours.")
            .append("<br><br><a href=\""+ url +"\" target=\"_blank\"><button> CONTINUE </button></a>")
            .toString();

实际上，如果要实现基于服务器的解决方案，则应该查看Java Server Pages（JSP）或Java Server Faces（JSF）。

Answer 2

我喜欢用String.format()：

   String customerMessage = String.format("Hi, We have received your request. Your account will be unblocked within 48 hours.\n<br><br><a href=\"%s\" target=\"_blank\"><button> CONTINUE </button></a>", url);
