sqlaction - Database persistence layer tool based auto-gen JDBC code

1. overview

sqlaction is a Database persistence layer tool based auto-gen JDBC code.

2. A demo

2.1. Create Table DDL

ddl.sql

CREATE TABLE `sqlaction_demo` (
  `id` int(11) NOT NULL AUTO_INCREMENT COMMENT '编�',
  `name` varchar(32) COLLATE utf8mb4_bin NOT NULL COMMENT '�字',
  `address` varchar(128) COLLATE utf8mb4_bin DEFAULT NULL COMMENT '地�',
  PRIMARY KEY (`id`),
  KEY `sqlaction_demo` (`name`)
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_bin

2.2. Create Java Project

Add jar "mysql-connector-java-X.Y.Z.jar".

Create dbserver.conf.json in Java package folder.

{
	"driver" : "com.mysql.jdbc.Driver" ,
	"url" : "jdbc:mysql://127.0.0.1:3306/calvindb?serverTimezone=GMT" ,
	"user" : "calvin" ,
	"pwd" : "calvin"
}

Create sqlaction.conf.json in Java package folder.

{
	"database" : "calvindb" ,
	"tables" : [
		{
			"table" : "sqlaction_demo" ,
			"sqlactions" : [
				"SELECT * FROM sqlaction_demo" ,
				"SELECT * FROM sqlaction_demo WHERE name=?" ,
				"INSERT INTO sqlaction_demo" ,
				"UPDATE sqlaction_demo SET address=? WHERE name=? @@METHOD(updateAddressByName)" ,
				"DELETE FROM sqlaction_demo WHERE name=?"
			]
		}
	] ,
	"javaPackage" : "xyz.calvinwilliams.sqlaction.demo"
}

2.3. Executing sqlaction

pp.bat

java -Dfile.encoding=UTF-8 -classpath "D:\Work\sqlaction\sqlaction.jar;D:\Work\mysql-connector-java-8.0.15\mysql-connector-java-8.0.15.jar" xyz.calvinwilliams.sqlaction.gencode.SqlActionGencode
