自建生成代码工具（暂支持Spring boot +JPA）(更新中)

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.*;

Spring Boot JPA 连接数据库

本文将介绍如何在Spring Boot 工程中添加JPA作为持久化方式. 修改 pom.xml 依赖 与上一篇介绍的 jdbc 不同的是 spring-boot-starter-jdbc 修改为 spring-boot-starter-data-jpa 即可,当然数据库驱动包也是不可少的,如下: <!-- MYSQL --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-conne

自制Https证书并在Spring Boot和Nginx中使用(转)

白话Https一文中, 介绍了Https存在的目的和工作原理,但多是偏向于原理性的介绍,本文介绍如何一步一步自制一个能够通过浏览器认证的Https证书,并讲解在Spring Boot环境和Nginx环境中服务器端的配置. 如果你还没有读过白话Https,我强烈建议你先去读一下.按照白话Https中的介绍,Https协议涉及到的主体主要有三个:客户端.服务端.以及CA机构.如下图所示: 在白话Https一文中,曾介绍一个服务要申请使用Https的流程.本文所介绍的流程,针对自制Https证书,更多
