1/自动生成的jar包：mybatis-generator-core-1.3.2.jar 

 2/generatorconfig.xml文件如：
<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE generatorConfiguration

3.1/  执行命令
java -jar mybatis-generator-core-1.3.0.jar -configfile  D:\test\generatorconfig.xml -overwrite 
这样基本就ok了。


3.2 Main方法执行

 List<String> warnings = new ArrayList<String>();
  boolean overwrite = true;
  File configFile = new File("src/generatorConfig.xml");
  ConfigurationParser cp = new ConfigurationParser(warnings);
  Configuration config;
  try {
   config = cp.parseConfiguration(configFile);
   DefaultShellCallback callback = new DefaultShellCallback(overwrite);
   MyBatisGenerator myBatisGenerator;
   try {
    myBatisGenerator = new MyBatisGenerator(config, callback,
      warnings);
    myBatisGenerator.generate(null);
   } catch (Exception e) {
    e.printStackTrace();
   }
