使用java启动mybatis generator

Posted 2020-07-11 An

1、java工程目录结构：

|src/main/java

　　|com.leslie.mybatis.generator

      　　|MybatisGeneratorUtil.java

|src/main/resources

　　generatorConfig.xml

|lib

　　|mybatis-3.3.0.jar

　　|mybatis-generator-core-1.3.2.jar

　　|mysql-connector-java-5.1.14-bin.jar

2、MybatisGeneratorUtil.java

package com.leslie.mybatis.generator;

import java.io.File;
import java.io.IOException;
import java.sql.SQLException;
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.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;

public class MybatisGeneratorUtil {
    public static void main(String[] args) {
        try {
            System.out.println("start generator ...");
            List<String> warnings = new ArrayList<String>();
            boolean overwrite = true;
            File configFile = new File(MybatisGeneratorUtil.class.getResource("/generatorConfig.xml").getFile());
            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);
            System.out.println("end generator!");
        } catch (IOException e) {
            e.printStackTrace();
        } catch (XMLParserException e) {
            e.printStackTrace();
        } catch (InvalidConfigurationException e) {
            e.printStackTrace();
        } catch (SQLException e) {
            e.printStackTrace();
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
}

3、generatorConfig.xml
