使用ctexart文档类和titletoc宏包，导致目录只显示在一页

首先，这个不是目录是正文，需要打印目录的话，在正文前添加命令 tableofcontens
其次，正文文本不分页是因为 LaTeX 的章节命令的原因，在 subsubsection{} 后添加文字就能正常分页了

如

\documentclass{ctexart}
\usepackage{titletoc}
\usepackage{zhlipsum}



\titlecontents{part}[0em]{}{\contentslabel{1em}}{}{\titlerule*{$\cdot$}\contentspage}
\titlecontents{section}[1em]{}{\contentslabel{1em}}{}{\titlerule*{$\cdot$}\contentspage}
\titlecontents{subsection}[3em]{}{\contentslabel{2em}}{}{\titlerule*{$\cdot$}\contentspage}
\titlecontents{subsubsection}[5em]{}{\contentslabel{3em}}{}{\titlerule*{$\cdot$}\contentspage}
\begin{document}
\tableofcontents
