如何在Eclipse IDE中查看Java的字节码？ [英] How to view Java's byte code in eclipse IDE?
问题描述
有时，在Eclipse中，我按下了组合键，这些键会将我带到显示我的.class文件（字节码）内容的编辑器页面。我似乎永远无法记住那个组合键是什么。
Sometimes, in Eclipse , i press a combination of keys which take me to the editor page that shows contents of my .class file (bytecode). I never seem to be able to remember what that key combination is.
有人可以让我知道吗？
或者换句话说，怎么能看到自己的字节码？
Or in other words, how can one see own bytecode?
推荐答案
Eclipse的默认类文件查看器显示源（请参阅VonC的答案）（如果它已与二进制文件关联），否则会给出类的类似于javap的视图（可以选择附加源代码）。我猜想它是您要寻找的后者。
Eclipse's default class file viewer shows the source (see VonC's answer) if it has been associated with the binaries, otherwise it gives a javap-like view of the class (with an option to attach source). I'm guessing it's the latter that you are looking for.
我从来没有找到一种方法可以强制Eclipse显示输出而不是链接的源。您可能想要的是一个Eclipse插件，该插件提供类似Javap的功能（或javap的接口）。寻找表明它们反汇编的插件（而不是像jad那样反编译的插件）。
I've never found a way to cleanly force Eclipse to show that output rather than the linked source. What you probably want is an Eclipse plug-in that provides Javap like functionality (or an interface to javap). Look for plugins stating they "disassemble" (as opposed to "decompile," like jad).
如果没有插件，则可以配置外部工具来执行javap，但它可能无法与其他eclipse功能配合使用。
Barring a plug-in, you could probably configure an external tool to perform javap but it might not play nicely with other eclipse features.
编辑：让我对以上内容进行清楚说明：如果您按F3键，则为Eclipse执行以下操作（通常，实际过程可能会略有不同）：
Let me be clear about the above: If you hit F3, Eclipse does the following (generally, the actual procedure might be slightly different):
- 解析目标（如果选择Java文件，它将将是Java文件本身；如果您正在选择或光标位于类名上方，则它将是类声明，类似于方法声明等）。
- 搜索构建路径（首先是同一项目）用于包含目标的Java文件。如果找到，则打开显示该Java源文件的可写编辑器。
-
对于类/方法声明，它将继续在构建路径的引用中搜索包含声明的类文件。 。如果找到，则
- Resolves the target (if you are selecting a Java file, it will be the Java file itself; if you are selecting or your cursor is over a class name it will be the class declaration, similar for a method declaration, etc).
- Searches the build path (same project first) for a Java file containing the target. If found, opens up an writable editor displaying that Java source file.
For class/method declarations, it continues searching references on your build path for a class file that contains the declaration. If it is found, then
a）如果类文件已附加源，则打开链接的Java文件的只读编辑器。
a) If the class file has had source attached to it, open up a read-only editor of the linked Java file.
b）如果类文件没有附加源，则打开一个只读面板，显示已编译的类文件的反汇编（类似Javap的）字节码。 / p>
b) If the class file does not have source attached to it, then open up a read-only panel showing the disassembled (javap-like) bytecode of the compiled class file.
我的猜测是您认为存在3.b的专用键序列，但我不知道认为没有。但是再次，我很想在这里被证明是错误的。
My guess would be that you're thinking there's a dedicated key sequence to 3.b), but I don't think there is. But again, I would love to be proven wrong here.
