No that is not possible. There is a feature request to create a <code>@SomeArgsConstructor</code> where you can specify a list of involved fields.

Full disclosure: I am one of the core Project Lombok developers.

blocks|key|1752039|text|或者，您可以使用@RequiredArgsConstructor。这为所有属于@NonNull或final的字段添加了一个构造函数。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1752040|见文档|1752041|entityMap|0|LINK|mutability|MUTABLE|url|https://projectlombok.org/features/Constructor.html^0|8|O|13|8|1C|5|0|1|2|0|0^^$0|@$1|2|3|4|5|6|7|P|8|@$9|Q|A|R|B|C]|$9|S|A|T|B|C]|$9|U|A|V|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|W|8|@]|D|@$9|X|A|Y|1|Z]]|E|$]]|$1|H|3|-4|5|6|7|10|8|@]|D|@]|E|$]]]|I|$J|$5|K|L|M|E|$N|O]]]]

Alternatively, you could use <code>@RequiredArgsConstructor</code>. This adds a constructor for all fields that are either <code>@NonNull</code> or <code>final</code>.
See the <a href="https://projectlombok.org/features/Constructor.html" rel="noreferrer">documentation</a>

blocks|key|145353|text|为了防止有帮助，初始化的final字段被排除在外。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|145354|@AllArgsConstructor

Just in case it helps, initialized <code>final</code> fields are excluded.
<pre><code>@AllArgsConstructor
class SomeClass {
 final String s;
 final int i;
 final List&lt;String&gt; list = new ArrayList&lt;&gt;(); // excluded in constructor
}

var x = new SomeClass(&quot;hello&quot;, 1);
</code></pre>
It makes sense especially for collections, or other mutable classes.
This solution can be used together with the <a href="https://stackoverflow.com/a/41219801/1121497">other solution here</a>, about using <code>@RequiredArgsConstructor</code>:
<pre><code>@RequiredArgsConstructor
class SomeClass2 {
 final String s;
 int i; // excluded because it's not final
 final List&lt;String&gt; list = new ArrayList&lt;&gt;(); // excluded because it's initialized
}

var x = new SomeClass2(&quot;hello&quot;);
</code></pre>

blocks|key|2748822|text|在某些情况下，一个很好的方法就是使用@Builder。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2748823|entityMap^0|I|8|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

A good way to go around it in some cases would be to use the <code>@Builder</code>

blocks|key|2748866|text|这可以使用lombok+@RequiredArgsConstructor和@NonNull的两个注释来完成。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|2748867|请找下面的例子|2748868|package+com.ss.model;

import+lombok.*;

@Getter

public+class+Employee+{

++++private+int+id;
++++@NonNull
++++private+String+firstName;
++++@NonNull
++++private+String+lastName;
++++@NonNull
++++private+int+age;
++++@NonNull
++++private+String+address;
}|code-block|syntax|javascript|2748869|然后您可以创建一个对象，如下所示|2748870|Employee+employee+=+new+Employee("FirstName",+"LastName",+27,+"Address");|2748871|entityMap^0|C|O|11|8|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@$9|T|A|U|B|C]|$9|V|A|W|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|X|8|@]|D|@]|E|$]]|$1|H|3|I|5|J|7|Y|8|@]|D|@]|E|$K|L]]|$1|M|3|N|5|6|7|Z|8|@]|D|@]|E|$]]|$1|O|3|P|5|J|7|10|8|@]|D|@]|E|$K|L]]|$1|Q|3|-4|5|6|7|11|8|@]|D|@]|E|$]]]|R|$]]

This can be done using two annotations from lombok @RequiredArgsConstructor and @NonNull.
Please find the example as follows
<pre><code>package com.ss.model;

import lombok.*;

@Getter
@Setter
@RequiredArgsConstructor
@ToString
public class Employee {

 private int id;
 @NonNull
 private String firstName;
 @NonNull
 private String lastName;
 @NonNull
 private int age;
 @NonNull
 private String address;
}
</code></pre>
And then you can create an object as below
<pre><code>Employee employee = new Employee(&quot;FirstName&quot;, &quot;LastName&quot;, 27, &quot;Address&quot;);
</code></pre>

blocks|key|2748904|text|Lombok是用来处理POJO的样板代码的。定制的构造函数/setters/getters/toString/copy等不在代码的样板端。对于这些情况，每个Java都提供了易于使用的代码生成器，以帮助您在短时间内完成任务。在你的例子中|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2748905|public+MyClass(String+firstName,+String+lastName)+{....}|code-block|syntax|javascript|2748906|比假设更有可读性和更有意义：|2748907|@AllArgsConstructor(exclude+=+"id",+exclude+=+"phone")|2748908|玩得开心!|2748909|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Lombok is meant to take care of the boilerplate code for your POJOs. Customized constructors/setters/getters/toString/copy etc are not on the boilerplate side of code. For these cases, every Java IDE provide easy to use code generators to help you do things in no time.
In your case a
<pre><code>public MyClass(String firstName, String lastName) {....}
</code></pre>
is much more readable and makes more sense than a hypothetic:
<pre><code>@AllArgsConstructor(exclude = &quot;id&quot;, exclude = &quot;phone&quot;)
</code></pre>
Have fun!

If I specify @AllArgsConstructor using Lombok, it will generate a constructor for setting all the declared (not final, not static) fields. 
Is it possible to omit some field and this leave generated constructor for all other fields?

如果我使用Lombok指定@AllArgsConstructor，它将生成一个构造函数来设置所有声明的字段(不是最终字段，而不是静态字段)。是否可以省略某些字段，并为所有其他字段保留生成的构造函数？
