采用命令行方式执行逆向工程
1、配置文件generatorConfig.xml 保存在目录:D:\E\workspace\eclipse\mybatis_generator
<?xmlversion="1.0"encoding="UTF-8"?>
<!DOCTYPEgeneratorConfiguration
PUBLIC"-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>

2、将驱动文件mysql-connector-java-8.0.11.jar和逆向工程mybatis-generator-core-1.3.7.jar保存到配置文件同一个目录下
3、命令行执行:
3.1) cd D:\E\workspace\eclipse\mybatis_generator
3.2)
jar包和配置文件在同一目录下执行如下命令:
java -jar mybatis-generator-core-1.3.7.jar -configfile generatorConfig.xml
jar包和配置文件在非同一目录下可执行如下命令:
java -jar D:\E\worksoft\apache-maven-3.6.0\repository\org\mybatis\generator\mybatis-generator-core\1.3.7\mybatis-generator-core-1.3.7.jar -configfile D:\E\workspace\eclipse\mybatis_generator\src\main\resources\generatorConfig.xml
4、生成的文件在配置的src/main/java目录下,即D:\E\workspace\eclipse\mybatis_generator\src\main\java目录下
5存在问题:
1)驱动包找不到,配置驱动包
<!--指定驱动文件,否则提示驱动不存在, jar包与配置文件非同一路径情况下使用绝对路径-->
<classPathEntry location="D:/E/worksoft/apache-maven-3.6.0/repository/mysql/mysql-connector-java/8.0.11/mysql-connector-java-8.0.11.jar"/>
<!--jar包与配置文件同一路径情况下-->
<!-- <classPathEntry location="mysql-connector-java-8.0.11.jar" /> -->
2) connectionURL 对实体 "characterEncoding" 的引用必须以 ‘;‘ 分隔符结尾
xml对&支持不好,采用&转义代替&
