首先感謝網際網路，以及前輩的demo
二話不說了直接上程式碼先
1、Java部分
package org.icpcheck.dataRiskOnRecordApp; 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 MybatisGenerator { public static void main(String[] args) { List<String> warnings = new ArrayList<String>(); boolean overwrite = true; try { File directory = new File(""); System.out.println(directory.getCanonicalPath());//獲取標準的路徑 System.out.println(directory.getAbsolutePath());//獲取絕對路徑 System.out.println(System.getProperty("user.dir")); File configFile = new File("D:/Software/Java_workSpace180712/dubbo/xxxx-parent/xxxxx-xxxxx/src/main/resources/generatorConfig.xml"); ConfigurationParser cp = new ConfigurationParser(warnings); Configuration config; config = cp.parseConfiguration(configFile); DefaultShellCallback callback = new DefaultShellCallback(overwrite); MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings); myBatisGenerator.generate(null); } catch (IOException | XMLParserException | InvalidConfigurationException | SQLException | InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } } }
2、xml配置檔案部分
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!--資料庫驅動--> <!--注意要保證執行MyBatis Generator的時候能夠找到mysql的connector--> <!-- location The full path name of a JAR/ZIP file to add to the classpath, or a directory to add to the classpath.--> <classPathEntry location="E:\xxxxx\mvn1209\mysql\mysql-connector-java\6.0.6\mysql-connector-java-6.0.6.jar"/> <!-- A unique identifier for this context.

3、需要jar包
<!-- https://mvnrepository.com/artifact/org.mybatis.generator/mybatis-generator-core --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.7</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.7</version> </dependency>
4、資料庫自建謝謝
5、工程結構
5、斧正！！！
