我正在使用 lstlisting 包将源代码放入我的 pdf 文件中：
\documentclass{scrbook}
\usepackage{listings}
\lstset{ %
language=xml,
basicstyle=\footnotesize, % the size of the fonts that are used for the code
numbers=none, % where to put the line-numbers
xleftmargin=2em,
numberstyle=\footnotesize, % the size of the fonts that are used for the line-numbers
stepnumber=2, % the step between two line-numbers. If it's 1, each line will be numbered
numbersep=5pt, % how far the line-numbers are from the code
backgroundcolor=\color{white}, % choose the background color. You must add \usepackage{color}
showspaces=false, % show spaces adding particular underscores
showstringspaces=false, % underline spaces within strings
showtabs=false, % show tabs within strings adding particular underscores
frame=yes, % adds a frame around the code
tabsize=2, % sets default tabsize to 2 spaces
captionpos=b, % sets the caption-position to bottom
breaklines=true, % sets automatic line breaking
breakatwhitespace=false, % sets if automatic breaks should only happen at whitespace
title=\lstname, % show the filename of files included with \lstinputlisting;
% also try caption instead of title
escapeinside={(*}{*)}, % if you want to add a comment within your code
morekeywords={*,...}, % if you want to add more keywords to the set
keywordstyle=\color[rgb]{0,0,1},
commentstyle=\color[rgb]{0.133,0.545,0.133},
stringstyle=\color[rgb]{0.627,0.126,0.941}
}
\begin{document}
\begin{lstlisting}[language=java,caption={MyCaption}
\label{lst:myLabel}]
See Code-Listing \ref{lst:myLabel}.
\end{document}
问题是，在标题中我看到了（正确的）“清单 7.2”，在我的文本中我看到了“5”，但我也希望那里有“7.2”:-)

您必须在键中提供标签：
\begin{lstlisting}[language=java,caption={MyCaption},label=lst:myLabel]
手册的第 16 页（但不太容易找到）。
