我用来listings在文档中列出代码，我希望代码显示在具有圆角和灰色背景颜色的框架中。但是背景溢出了框架，就好像框架是正方形一样。
这是一个简单的例子：
\documentclass[a4paper, 11pt]{article}
\usepackage{color}
\usepackage{listings}
\begin{document}
\lstset{basicstyle=\footnotesize\ttfamily, xleftmargin=1em, xrightmargin=1em,
frame=single, framesep=1em, frameround=tttt,
backgroundcolor=\color[rgb]{0.85, 0.85, 0.85}, captionpos=b}
\begin{lstlisting}
bla bla bla
\end{lstlisting}
\end{document}
结果：
有什么办法可以修复这个问题吗？
编辑
我现在可以让示例运行了。问题是由于所需软件包的版本太旧造成的。

根据我评论中的链接，我创建了一个可以在其中使用-environment 的环境lstlistings：
代码
\documentclass[a4paper, 11pt]{article}
%\usepackage{color} loaded by tikz and you should use xcolor instead ...
\usepackage{listings}
\usepackage{tikz}
% set listings
\lstset{%
basicstyle=\footnotesize\ttfamily,
% captionpos=t,
framesep=5em,
}
% define backgroundcolor
\definecolor{bggray}{rgb}{0.85, 0.85, 0.85}
% add frame environment
\usepackage[%
framemethod=tikz,
skipbelow=\topskip,
skipabove=\topskip
]{mdframed}
\mdfsetup{%
leftmargin=0pt,
rightmargin=0pt,
backgroundcolor=bggray,
middlelinecolor=black,
roundcorner=10
}
\usepackage{etoolbox}% >= v2.1 2011-01-03
\BeforeBeginEnvironment{lstlisting}{\begin{mdframed}\vspace{-0.7em}}
\AfterEndEnvironment{lstlisting}{\vspace{-0.5em}\end{mdframed}}
% needed for \lstcapt
\def\ifempty#1{\def\temparg{#1}\ifx\temparg\empty}
% make new caption command for listings
\usepackage{caption}
\newcommand{\lstcapt}[2][]{%
\ifempty{#1}%
\captionof{lstlisting}{#2}%
\else%
\captionof{lstlisting}[#1]{#2}%
\fi%
\vspace{0.75\baselineskip}%
}
% only for testing ...
\usepackage[english]{babel}
\usepackage{blindtext}
\begin{document}
\blindtext
%
\begin{lstlisting}
Foo {
Bazzzzz }
Bar
\end{lstlisting}
\lstcapt{Test}
%
\blindtext
%
\begin{lstlisting}
Foo
\end{lstlisting}
\lstcapt[Short descrpition]{Another long description. Another long description.
Another long description.}
%
\blindtext
%
\lstlistoflistings
\end{document}
结果
局限性
此解决方案仅适用于非分页列表。请参阅答案测试某个段落是否有分页符？了解这是如何实现的。

更新
我将这三行代码添加到上面的示例中，lstlisting直接修补环境。因此无需\begin{code} … \end{code}再手动输入。
\usepackage{etoolbox}
\BeforeBeginEnvironment{lstlisting}{\begin{code}}
\AfterEndEnvironment{lstlisting}{\end{code}}
更新 2
我创建了一个新命令\lstcapt[<Short>]{<Text>}来设置框架外的标题，并将其添加到上面的示例代码中。
更新 3
我按照 Marco 的建议改用 mdframed 而不是直接使用 TikZ 来解决分页问题。
更新 4
请注意，此代码需要etoolboxv2.1 或更高版本……

答案2
mdframed您还可以使用允许分页的包：
\documentclass[a4paper, 11pt]{article}
\usepackage{listings}
\lstset{%
basicstyle=\footnotesize\ttfamily,
abovecaptionskip=0pt,belowcaptionskip =0pt,
framextopmargin=-\topsep,
}
% define backgroundcolor
\usepackage[style=1,skipbelow=\topskip,skipabove=\topskip]{mdframed}
\definecolor{bggray}{rgb}{0.85, 0.85, 0.85}
\mdfsetup{leftmargin=20pt,rightmargin=20pt,backgroundcolor=bggray,middlelinecolor=black,roundcorner=15}
\BeforeBeginEnvironment{lstlisting}{\begin{mdframed}\vskip-.5\baselineskip}
\AfterEndEnvironment{lstlisting}{\end{mdframed}}
% only for testing ...
\usepackage[english]{babel}
\usepackage{blindtext}
\begin{document}
\blindtext
%
\begin{lstlisting}[caption=foo]
Foo {
Bazzzzz }
Bar
\end{lstlisting}
%\lstcapt{Test}
%
\blindtext
%
\begin{lstlisting}
Foo
Foo {
Bazzzzz }
Bar
Foo {
Bazzzzz }
Bar
Foo {
Bazzzzz }
Bar
Foo {
Bazzzzz }
Bar
Foo {
Bazzzzz }
Bar
Foo {
Bazzzzz }
Bar
\end{lstlisting}
\blindtext
%
\lstlistoflistings
\end{document}
