spring-boot开发微信小程序后台
spring boot与mybatis整合,mybatis逆向工程生成pojo、mapper、dao
逆向工程目录结构:
GeneratorDisplay:启动类,加载数据库文件。
package cn.zoubin.mybatis.utils;
import java.io.File;
import java.util.ArrayList;
import java.util.List;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.internal.DefaultShellCallback;
public class GeneratorDisplay {
public void generator() throws Exception{
List<String> warnings = new ArrayList<String>();
boolean overwrite = true;
//指定 逆向工程配置文件
File configFile = new File("generatorConfig.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = cp.parseConfiguration(configFile);
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config,
callback, warnings);
myBatisGenerator.generate(null);
}
public static void main(String[] args) throws Exception {
try {
GeneratorDisplay generatorSqlmap = new GeneratorDisplay();
generatorSqlmap.generator();
} catch (Exception e) {
e.printStackTrace();
}
}
}
MyMapper:固定接口,生成dao类的继承父类,不能被扫描。

//TODO
//FIXME 特别注意,该接口不能被扫描到,否则会出错

generatorConfiguration.xml:配置文件,有关数据库,生成内容都在里面。

在配置文件中配置好所有信息后,就可以启动启动类,生成的代码、类都在你指定的包内。
