Eclipse - 查看一个类的哪些方法在另一个类中使用？

Eclipse - see which methods of one class are used in another?

提问by Konrad Garus

With Eclipse, given the following classes:

使用 Eclipse，给出以下类：

class Dao {
    public void one() {}
    public void two() {}
    public void three() {}
}

class ServiceA {
    Dao dao;
    public void a() {
        dao.one();
        dao.two();
    }
    public void b() {
        dao.one();
    }
}

class ServiceB {
    Dao dao;
    public void z() {
        dao.two();
        dao.three();
    }
}

... is it possible to see a list of all Daomethods referenced from ServiceA? I'm looking for one view that will show that ServiceAuses one()and two()(don't mind it if one()is listed twice).

...是否可以看到所有Dao引用的方法的列表ServiceA？我正在寻找一个视图，该视图将显示ServiceA使用one()和two()（如果one()列出两次，请不要介意）。

I know how to see callers of one specific method. I really need a list of all methods referenced within a class. Think of legacy code orders of magnitude larger: dao and services that have tens (hundreds?) of methods. I don't feel like going through call hierarchy method by method.

我知道如何查看一种特定方法的调用者。我真的需要一个类中引用的所有方法的列表。想想更大数量级的遗留代码：具有数十（数百？）个方法的 dao 和服务。我不想逐个调用层次结构方法。

Actually you can click by right mouse button at Dao method and then click at 'Open Call Hierarchy Ctrl+Alt+H' and Eclipse will find for you all Dao method calls.

实际上，您可以在 Dao 方法上单击鼠标右键，然后单击“Open Call Hierarchy Ctrl+Alt+H”，Eclipse 将为您找到所有 Dao 方法调用。

Yes, except for that I need it from the opposite side. See all methods called from Service, not all calls of Dao.conreteMethod().

是的，除此之外，我需要从相反的一侧使用它。查看从 Service 调用的所有方法，而不是所有 Dao.conreteMethod() 调用。

– 我需要创建一个新答案，因为我将使用两张图片来说明我的观点。（评论中不能使用图片）

'Ctrl+Alt+H' brings up call hierarchy, as has been mentioned here by other people.

'Ctrl+Alt+H' 调出呼叫层次结构，正如其他人在此处提到的那样。

Then you need to click on these icons, depending on what you need:

然后您需要单击这些图标，具体取决于您的需要：

What about VonC's answer here(it's the one with the saw-tooth-rimmed screenshot image inside)?

VonC在这里的回答怎么样（里面有锯齿边框的截图）？

Here I've used CTRL-H to code-search for calls to Dao.one().

在这里，我使用 CTRL-H 来代码搜索对 Dao.one() 的调用。

Result: In the search result view, there's another little icon "group by type).

结果：在搜索结果视图中，还有一个小图标“按类型分组”。

Press Ctrl+Shift+Gto perform a search which shows all the places where your method or selected class is being used.

按Ctrl+Shift+G执行搜索，其中显示使用您的方法或所选类的所有位置。

Additionally, you can temporarily set all the publicmethods to privatevisibility and check the places where errors are popping up.

此外，您可以临时将所有public方法设置为private可见性并检查出现错误的位置。

回答by bhagyas

You can use a Code Coverage plugin/tool for this.

您可以为此使用代码覆盖率插件/工具。

For example:

例如：

• Dependency Analyzer (http://www.dependency-analyzer.org/)
• Codecover
• UCDetector
• FindBugs
• PMD
• CodePro Analytics (free from Google)

• 依赖分析器 (http://www.dependency-analyzer.org/)
• 代码覆盖
• UC探测器
• 查找错误
• PMD
• CodePro 分析（免费来自 Google）

If you right click on a method and select Open Call Hierarchy you all get the list of all the classes using the particular method.

如果您右键单击一个方法并选择 Open Call Hierarchy，您将获得使用特定方法的所有类的列表。
