如何为java项目生成调用图

发布于 2024-10-17 13:31:08 字数 399 浏览 5 评论 0原文

是否可以生成应用程序的全局调用图？

基本上我试图找到应用程序中最重要的类。

我正在寻找 Java 的选项。

我尝试过 Doxy Gen，但它只生成继承图。

我当前的脚本：

#! /bin/bash

echo "digraph G
{"
find $1 -name \*.class |
    sed s/\\.class$// |
    while read x
    do
        javap -v $x | grep " = class" | sed "s%.*// *%\"$x\" -> %" | sed "s/$1\///" | sed "s/-> \(.*\)$/-> \"\1\"/"
    done
echo "}"

Is it possible to generate a global call graph of an application?

Basically I am trying to find the most important class of an application.

I am looking for options for Java.

I have tried Doxy Gen, but it only generates inheritance graphs.

My current script:

#! /bin/bash

echo "digraph G
{"
find $1 -name \*.class |
    sed s/\\.class$// |
    while read x
    do
        javap -v $x | grep " = class" | sed "s%.*// *%\"$x\" -> %" | sed "s/$1\///" | sed "s/-> \(.*\)$/-> \"\1\"/"
    done
echo "}"

javap -v 和一些 Perl 将为您提供类之间的依赖关系。您可以使解析器稍微复杂一些并获取方法之间的依赖关系。

更新：或者如果您有 *nix 或 cygwin，您可以通过添加页眉和页脚获取依赖项列表

find com/akshor/pjt33/image -name \*.class |
  sed s/\\.class$// |
    while read x
    do
      javap -v $x | grep " = class" | sed "s%.*// *%$x -> %"
    done

，然后可以将其传递给 dot 以呈现图形。如果您只想知道大多数其他类使用哪些类，正如您的问题所暗示的那样，那么

find com/akshor/pjt33/image -name \*.class |
  sed s/\\.class$// |
    while read x
    do
      javap -v $x | grep " = class" | sed "s%.*// *%%"
    done |
      sort | uniq -c | sort -n

javap -v and a bit of perl will get you dependencies between classes. You can make your parser slightly more sophisticated and get dependencies between methods.

Update: or if you have either a *nix or cygwin you can get a list of dependencies as

find com/akshor/pjt33/image -name \*.class |
  sed s/\\.class$// |
    while read x
    do
      javap -v $x | grep " = class" | sed "s%.*// *%$x -> %"
    done

Add a header and a footer and you can pass it to dot to render a graph. If you just want to know which classes are used by the most other classes, as your question implies, then

find com/akshor/pjt33/image -name \*.class |
  sed s/\\.class$// |
    while read x
    do
      javap -v $x | grep " = class" | sed "s%.*// *%%"
    done |
      sort | uniq -c | sort -n
