Automatically create builder for class in Eclipse
提问by hasanghaforian
Is there a way to use an automatic builderto create builder (Joshua Bloch's Builder Pattern) for classes in Eclipse? For example an option in the menu, a plugin or something else. I could not find anything under "Refactor".
有没有办法使用自动构建器为 中的类创建构建器（Joshua Bloch 的构建器模式）Eclipse？例如菜单中的选项、插件或其他东西。我在“ Refactor”下找不到任何内容。

Maybe I am late to the party.
也许我参加聚会迟到了。
Eclipse on its own does not provide a way to generate code to support builder pattern. However it can be extended through plugins to enhance the functionality.
Eclipse 本身不提供生成代码以支持构建器模式的方法。但是，它可以通过插件进行扩展以增强功能。
There is this plugin that I use this:
有这个插件，我用这个：

You could add your own template window -> preferences -> java -> editor -> templates and this will be activated with the content proposal but not by refactor action
您可以添加自己的模板窗口 -> 首选项 -> java -> 编辑器 -> 模板，这将通过内容提案激活，但不会通过重构操作激活

You may want to look at lombokannotations to generate builders without the boiler plate code. For example:
您可能希望查看lombok注释以生成没有样板代码的构建器。例如：
@Builder
public class MyPojo {
private String name;
}
MyPojoBuilder.builder().name("yourame").build();
The limitation is that this doesn't seem to work with abstract classes.
限制是这似乎不适用于抽象类。

package ${cls.package.name};
public class ${cls.shortName}Builder {
public static ${cls.name}Builder builder() {
return new ${cls.name}Builder();
}
<% for(field in cls.fields) {%>
private ${field.type.name} ${field.name};

<% for(field in cls.fields) {%>
public ${cls.name}Builder ${field.name}(${field.type.name} ${field.name}) {
this.${field.name} = ${field.name};
return this;
}
<% } %>
public ${cls.name} build() {
final ${cls.name} data = new ${cls.name}();
<% for(field in cls.fields) {%>
data.${field.setter.name}(this.${field.name});

return data;
