前言

Project Lombok是一个java库，它可以自动插入编辑器和构建工具，为您的java程序锦上添花。
再也不要写另一个getter或equals方法了，只要有一个注释，你的类就有一个功能齐全的生成器，自动记录变量等等。

一、准备

1. 安装插件

IntelliJ:

• Go to File > Settings > Plugins
• Click on Browse repositories…
• Search for Lombok Plugin
• Click on Install plugin
• Restart IntelliJ IDEA
  

2. 引入库

<!-- https://mvnrepository.com/artifact/org.projectlombok/lombok -->
<dependency>
    <groupId>org.projectlombok</groupId>
    <artifactId>lombok</artifactId>
    <version>1.18.32</version>
    <scope>provided</scope>
</dependency>

二、使用

1.实体类

package org.example.springboot3.po;

import lombok.AllArgsConstructor;
import lombok.Builder;
import lombok.Getter;
import lombok.NoArgsConstructor;
import lombok.Setter;
import lombok.ToString;
import java.text.SimpleDateFormat;
import java.util.Date;

/**
 * Create by zjg on 2024/5/19
 */
@Builder
@AllArgsConstructor
@NoArgsConstructor
@Getter
@Setter
@ToString
public class Summons {
    private int id;
    private String defendantName;
    private String defendantGende;
    private int defendantAge;
    private String defendantUnit;
    private String caseNature;
    private String plaintiffName;
    private Date hearingDate;
    private String hearingVenue;
    private String courtName;
    private String courtAddress;
    private String contactPhone;
    private Date summonsDate;
    public String format(Date date,String pattern) {
        return new SimpleDateFormat(pattern).format(date);
    }
}

2.测试类

package org.example.springboot3.controller;

import lombok.extern.log4j.Log4j2;
import org.example.springboot3.po.Summons;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import java.time.ZonedDateTime;
import java.util.Date;

/**
 * Create by zjg on 2024/5/19
 */
@Log4j2
@RestController
@RequestMapping("/lombok/")
public class LombokController {
    @RequestMapping("001")
    public Summons lombok001(){
        Summons summon = Summons.builder().id(1).defendantName("被告姓名").defendantGende("男").defendantAge(25).defendantUnit("被告单位")
                .caseNature("案例性质").plaintiffName("原告姓名").hearingDate(Date.from(ZonedDateTime.now().plusDays(7).withHour(10).withMinute(0).withSecond(0).toInstant()))
                .hearingVenue("听证会地点").courtName("法院名称").courtAddress("法院地址").contactPhone("联系电话").summonsDate(new Date()).build();
        log.info(summon);
        return summon;
    }
}

3. 输出

[2024-05-19 11:33:17.140][http-nio-8080-exec-3][INFO]- org.example.springboot3.controller.LombokController.lombok001(LombokController.java:22) - Summons(id=1, defendantName=被告姓名, defendantGende=男, defendantAge=25, defendantUnit=被告单位, caseNature=案例性质, plaintiffName=原告姓名, hearingDate=Sun May 26 10:00:00 CST 2024, hearingVenue=听证会地点, courtName=法院名称, courtAddress=法院地址, contactPhone=联系电话, summonsDate=Sun May 19 11:33:17 CST 2024)
