Question

我正在关注youtube上的教程，但我可以使用lombok专门运行AllArgsConstructor。这是一个maven项目。

我有这个pojo；


    package com.example.producer;

    import lombok.AllArgsConstructor;
    import lombok.Data;
    import lombok.NoArgsConstructor;

    @Data
    @AllArgsConstructor
    @NoArgsConstructor
    public class Reservation {
        private String id;
        private String name;
    }

我有这个测试：


    package com.example.producer;

    import org.junit.Test;
    import org.junit.Assert;

    public class ReservationPojoTest {
        @Test
        public void create() throws Exception {
            Reservation re = new Reservation("1", "Jane");
            Assert.assertEquals(re.getName(), "Jane");
        }
    }

这是我的pom.xml

在Visual Studio代码中运行测试时，它向我显示此错误：

未定义构造函数Reservation（String，String）

这是整个项目； https://github.com/civilian/java-spring-learning

您将需要一个插件来使Visual Studio Code理解Lombok批注。此处介绍了所有内容：https://projectlombok.org/setup/vscode

将vscode-lombok plugin添加到Visual Studio Code IDE中以添加lombok支持。


按Ctrl + Shift + X打开扩展程序管理器。

键入lombok来查找插件，然后单击install。

在询问时重新加载VS代码。
