创建一个输出相同标记但略有改动的命令

我需要在我的文档中多次插入以下标记：

\usepackage{fullpage}
\usepackage{listings}
\usepackage{xcolor}

\definecolor{mygray}{HTML}{3E3E3E}
\definecolor{fucsia}{HTML}{F92672}
\definecolor{lightblue}{HTML}{2E6B70}
\definecolor{aquamarine}{HTML}{60B6BC}

\hypersetup{
    colorlinks=true,
    linkcolor=black,

}
\lstset{

    %identifierstyle=\color{lightblue},
    stringstyle=\color{orange}
}

\newtcbox{\mybox}{nobeforeafter,colframe=bggray,colback=bggray,boxrule=0.5pt,arc=4pt,

Java prevede i seguenti tipi di dato:
\begin{itemize}
    \item tipi base (o primitivi): void, boolean, int, char, float, double, short, byte;
    \item riferimenti ad oggetti;
    \item array;
    \item tipo nullo.
\end{itemize}

\subsection{Esercizio 4 del 30 gennaio 2008}
Il codice sorgente Java compila, fornendo la seguente classe \texttt{B}:

\begin{lstlisting}
public class B {
    public static int x;

    public B() {}
    public static A copia(B b) { return new A(); }
    public static B copia (int n) { return new B(); }
    public int g() { return 0; }

}
\end{lstlisting}

\end{document}

我每次唯一需要更改的是链接。我想知道是否可以创建一个新命令，接受 URL 作为参数并输出代码片段中的标记，这样我就不必一遍又一遍地输入它了。

像这样的宏应该可以解决问题：

\newcommand{\mymessage}[1]{%
    \mybox{\hspace{6pt}\raisebox{-4pt}%
    {\includegraphics[scale=.30,keepaspectratio=true]{img/save_32.png}}\hspace{10pt}%
    \myinsidebox{\color{white}%
    {I file \texttt{.java} relativi alla lezione possono essere scaricati}%
    \href{#1}{cliccando qua}.}}}

它可以被这样调用：

\mymessage{http://mybrilliantlink.com/download/123456}
