Easycode is a plug-in of idea, which can directly generate entities, controllers, services, dao, and mappers for data tables without any coding. It is simple and powerful.

1. Installation (EasyCode)

I have already installed it here.

It is recommended that you install a plug-in called Lombok.

Lombok can automatically generate constructors, getters/setters, equals, hashcode, and toString methods for properties at compile time through annotations. The magic that happens is that there are no getter and setter methods in the source code, but there are getter and setter methods in the compiled bytecode file.

2. Create a database

-- ----------------------------
-- Table structure for user
-- ----------------------------
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL,
`username` varchar(20) DEFAULT NULL,
`sex` varchar(6) DEFAULT NULL,
`birthday` date DEFAULT NULL,
`address` varchar(20) DEFAULT NULL,
`password` varchar(20) DEFAULT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
SET FOREIGN_KEY_CHECKS = 1;

3. Configure the connection database in IDEA

Before this, create a new Springboot project, which should be relatively simple.
After building the SpringBoot project, as shown in the figure below, find the Database
## Proceed as shown in the figure below:
##Then fill in the database name, user name, password. Just click OK. In this case, IDEA is ready to connect to the database.

4. Start generating code

Find the table you want to generate here, then right-click, and the section shown below will appear.
点击1所示的位置，选择你要将生成的代码放入哪个文件夹中，选择完以后点击OK即可。
勾选你需要生成的代码，点击OK。
这样的话就完成了代码的生成了，生成的代码如下图所示：

5、pom.xml

6、Application.yml

server:
  port: 8089
spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/database?useUnicode=true&characterEncoding=UTF-8
    username: root
    password: 123456
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver

mybatis:
mapper-locations: classpath:/mapper/*Dao.xml
typeAliasesPackage: com.vue.demo.entity

Copy after login

7、启动项目

在启动项目之前，我们需要先修改两个地方。

在dao层加上@mapper注解
在启动类里面加上@MapperScan("com.vue.demo.dao")注解。
启动项目
测试一下
