Eclipse how to refactor variable names?
提问by Ben
In my 15 years old java project, Standard Java Conventions are not respected, and first letter of variable names is often capitalized.
在我 15 岁的 Java 项目中，不遵守标准 Java 约定，变量名的首字母通常大写。
I would like to refactor my project to lower case first letter of variables names, especially in method signatures :
我想将我的项目重构为小写变量名称的首字母，尤其是在方法签名中：
public void creerProfil(String CodeProfil, Profil ProfilACreer) throws Exception {
...
}
should be :
应该 ：
public void creerProfil(String codeProfil, Profil profilACreer) throws Exception {
...
}
If you have any idea of plugin which could do that, I would be glad to hear it :)
如果您对可以做到这一点的插件有任何想法，我会很高兴听到它:)

No plugins needed, rightclick on the variable name, then "refactor" -> "rename". However, never tried before, I don't know how reliable it is among the whole project.
不需要插件，右键单击变量名称，然后“重构”->“重命名”。但是，之前没有尝试过，不知道在整个项目中它的可靠性如何。

To answer you simply, right Click variable name > refactor > rename. But you have to do it variable by variable.I case you want to find all the violation of variable names at one go, use checkstyle Checkstyle naming convention
简单地回答你，右键单击变量名称>重构>重命名。但是你必须逐个变量来做。如果你想一次性找出所有违反变量名的，使用 checkstyle Checkstyle 命名约定
Checkstyle will give you list of all the places code convention is not followed and then you can refactor.
Checkstyle 会给你列出所有没有遵循代码约定的地方，然后你可以重构。

Quoting from eclipse docsfor Rename refactoring:-
从Eclipse 文档中引用重命名重构：-
Renames the selected element and (if enabled) corrects all references to the elements (also in other files).
Available: Methods, method parameters, fields, local variables, types, type parameters, enum constants, compilation units, packages, source folders, projects and on a text selection resolving to one of these element types
Shortcut: Alt + Shift + R
重命名所选元素并（如果启用）更正对元素的所有引用（也在其他文件中）。
可用：方法、方法参数、字段、局部变量、类型、类型参数、枚举常量、编译单元、包、源文件夹、项目以及解析为这些元素类型之一的文本选择
快捷键：Alt + Shift + R
For Refactoring a method's signature/parameters:-
对于重构方法的签名/参数：-
Changes parameter names, parameter types, parameter order and updates all references to the corresponding method. Additionally, parameters and thrown exceptions can be removed or added and method return type and method visibility can be changed.
Available: Methods or on text selection resolving to a method
Shortcut: Alt + Shift + C
更改参数名称、参数类型、参数顺序并更新对相应方法的所有引用。此外，可以删除或添加参数和抛出的异常，并且可以更改方法返回类型和方法可见性。
可用：方法或解析为方法的文本选择
快捷键：Alt + Shift + C

If you are on windows/ubuntu platform use alt+shift+Ror on mac use command+option+r. It will refactor all the occurences where thatvariable is used.
如果您在 windows/ubuntu 平台上使用alt+shift+R或在 mac 上使用command+option+r。它将重构使用该变量的所有事件。
To get the list of shortcuts available in eclipse, use ctrl+shift+Lin windows/ubuntu and command+shift+lin mac.
要获取 eclipse 中可用的快捷方式列表，请ctrl+shift+L在 windows/ubuntu 和command+shift+lmac 中使用。

Refactor within a file: Use Alt+Shift+R
在文件内重构：使用 Alt+Shift+R
Refactor within multiple files: Use Alt+Shift+R two times (To make it simple, hold Alt+Shift and press R two times).
在多个文件中重构：使用 Alt+Shift+R 两次（为了简单起见，按住 Alt+Shift 并按 R 两次）。
This behaviour works with Eclipse Oxygen, Windows.
Version: Oxygen.3a Release (4.7.3a)
Build id: 20180405-1200
此行为适用于 Eclipse Oxygen、Windows。
版本：Oxygen.3a 发布 (4.7.3a) 版本号
