Archetype是一个Maven项目模板工具包。通过Archetype我们可以快速搭建Maven项目。通常我们使用idea创建maven工程的时候都会选择Archetype来创建项目maven中常用的Archetype

# 到项目根目录执行命令 mvn archetype:create-from-project
## 进入archetype目录 cd target/generated-sources/archetype/ mvn install ## 生成archetype-catalog.xml文件 mvn archetype:crawl

-DarchetypeGroupId :archetype-catalog.xml中的groupId
-DarchetypeArtifactId :archetype-catalog.xml中的artifactId
-DarchetypeVersion :archetype-catalog.xml中的version
-DarchetypeCatalog :使用模式本地和远程
-DgroupId :需要生成project的maven groupId
-DartifactId :需要生成project的maven artifactId
-Dversion :需要生成project的maven version
生成的项目自带mybatis代码生成工具,开箱即用,直接修改关键参数如:数据库,表明等及其他简单配置就可以直接生成默认的赠删改查功能,直接运行!!!直接使用!!!
public class Generator {
public static void main(String[] args) {
//module 自己想要生成的根工程名称 本工程为user
String module = "user";
//package name 在使用命令生成的时候指定的-DgroupId,本案例为com.test.user
String packageName = "com.test.user";
//author 作者名称
String author = "jour";
//database user name
String dbUserName = "root";
//database user password
String dbUserPassWord = "root";
//database
String dbDatabaseName = "user";
//table name
String tablePrefix = "user";
//database ip
String dbIpAddress = "127.0.0.1";
//当前生成类所在的模块名称 当前生成器所在的工程的名称 本案例在user-service中
MyBatisTemplate.setProjectPath("user-service");
MyBatisTemplate.generator(module, tablePrefix, packageName, author, dbUserName, dbUserPassWord, dbIpAddress, dbDatabaseName);
