我们努力的方向就是用更少的时间写出更高质量的代码，因此我们都需要借助一些工具来提高自己的开发效率。写代码有些年头了，慢慢的可以写一些东西来提高工作效率。主要会从Java后台和Android开始，暂时叫“Auto coding”，大家如果有更好的想法麻烦告诉我，谢谢。

1. 生成后台和管理端代码

　　往往我们做项目会先把表建好再进行编码，管理端有多相似的地方，所以通过表SQL利用AutoCoding所以大部分代码，再对部分部分地方手动调整就能先快速完成一个功能模块。

　　Spring boot JPA + layui 结构为例，暂时可以生成Entity、EntityModel、Repository、Service、ServiceImpl、Controller、list.jsp(数据列表功能)、add.jsp(新建数据功能)、update.jsp(更新数据功能)、detail.jsp(详情功能)。

示例：

用户表

CREATE TABLE `user` (
  `id` int(11) unsigned NOT NULL AUTO_INCREMENT COMMENT ‘ID‘,
  `account` varchar(50) NOT NULL COMMENT ‘账号‘,
  `password` varchar(50) NOT NULL COMMENT ‘密码‘,
  `nickname` varchar(20) NOT NULL COMMENT ‘昵称‘,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

下面是生成的相关代码

import javax.persistence.*;

@Entity
@Table(name = "user")
public class User extends BaseEntity{

    // 账号
    @Column(name = "account")
    private String account;
 
    // 密码
    @Column(name = "password")
    private String password;
 
    // 昵称
    @Column(name = "nickname")
    private String nickname;
 
    public String getAccount() {
        return account;
    }
 
    public void setAccount(String account) {
        this.account = account;
    }
 
    public String getPassword() {
        return password;
    }
 
    public void setPassword(String password) {
