当@RequiredargsConstructor与@Builder结合时，我无法使其工作

Question

import lombok.RequiredArgsConstructor;

@RequiredArgsConstructor
public class Test
{
   private final String email;
   private final String name;
   private String password;
}

一切工作正常，正如预期的那样，但是当我添加@Builder注释时：

import lombok.Builder;
import lombok.RequiredArgsConstructor;

@RequiredArgsConstructor
@Builder
public class Test
{
   private final String email;
   private final String name;
   private String password;
}

在生成过程中，我得到以下错误：

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project example: Compilation failure
[ERROR] /C:/[...]/Test.java:[9,1] constructor Test in class [...]Test cannot be applied to given types;
[ERROR]   required: java.lang.String,java.lang.String
[ERROR]   found: java.lang.String,java.lang.String,java.lang.String
[ERROR]   reason: actual and formal argument lists differ in length

这是龙目虫还是我做错了什么？

import lombok.AccessLevel;
import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.RequiredArgsConstructor;
import okhttp3.OkHttpClient;

import java.util.concurrent.TimeUnit;

@RequiredArgsConstructor
@AllArgsConstructor(access = AccessLevel.PACKAGE)
@Builder
public class Test
{
   private final String email;
   private final String name;
   private String password;

   @Builder.Default
   private final long timeout = 60000L;

   private OkHttpClient okHttpClient = new OkHttpClient.Builder().readTimeout(timeout, TimeUnit.MILLISECONDS).build();
}

[ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:3.8.0:compile (default-compile) on project example: Compilation failure
[ERROR] /C:/[...]/Test.java:[25,79] variable timeout might not have been initialized

您需要添加@AllArgsConstructor以使其可用于生成器。

如果您没有指定任何构造函数，@builder将创建一个，但是如果至少有一个构造函数，则不会。

试试这个：

import lombok.*;

@RequiredArgsConstructor
@AllArgsConstructor(access = AccessLevel.PACKAGE)
@Builder
public class Test
{
   private final String email;
   private final String name;
   private String password;
}
