生成在Eclipse中返回自身的设置器 [英] Generate setters that return self in Eclipse

问题描述

我想要我的设置器，以便我可以链接：

I'd like to have my setters so that I can chain them like:

myPojo.setX(x).setY(y);

通常我使用Eclipse生成setter但不幸的是代码模板对于设置器，我只能改变设置者的身体，而不是签名。

Usually I generate setters with Eclipse but unfortunately code template for setters allows me to change only the body of the setter, not the signature.

完成上述什么是最简单的方法？除了搜索和替换+手动编辑？ ：

What would be the easiest way to complete the above? Besides search-and-replace + manual editing? :)

推荐答案

我可以提供一种补丁，但不需要任何额外的安装。

I can offer a kind of patch that however does not require any additional installations.

转到窗口/首选项/ Java /代码样式/代码模板。编辑setter body模板如下：

Go to Window/preferences/Java/Code Style/Code templates. Edit "setter body" template as following:

${field} = ${param};
return this;

现在，当您运行generate getter and setter时，将创建如下设置器：

Now when you run "generate getters and setters" it will create setter like:

public void setMyField(String myField) {
    this.myField = myField;
    return this;
}

这显然是编译错误，因为方法类型是空隙。但是您可以使用 Ctrl-F ，并将所有public void set替换为 public YourClassName set 。

This obviously cause compilation error because the method type is void. But you can strike Ctrl-F and replace all 'public void set' by public YourClassName set.

这是一个补丁，但它的工作原理...

It is a patch, but it works...
