"http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >

<javaTypeResolver>

<!-- 实体类生成的位置 -->

（1）插件使用
（2）使用 java调用

import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.InvalidConfigurationException;

import org.mybatis.generator.internal.DefaultShellCallback;
import org.springframework.core.io.ClassPathResource;
import java.io.*;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
public class Test {
public static void uploadCaseList(String path) {
String [] fileNames=null;
File file = new File(path);
File [] fileNames1 = file.listFiles();
fileNames=new String [fileNames1.length];
for(int i=0;i<fileNames1.length;i++){
fileNames[i]=fileNames1[i].getAbsolutePath();
System.out.println(fileNames[i]);
}
File file1 = null;
BufferedReader br;
for (int i = 0; i < fileNames.length; i++) {
file1 = new File(fileNames[i]);
try {

String line = "";
int temp = 0;
for (int j = 0; (line = br.readLine()) != null; j++) {
String[] info =line.split("\\[@#@\\]",-1);
System.out.println(info[0]);
System.out.println(info[1]);
System.out.println(info[2]);
System.out.println();
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
public static void main(String[] args)
{
// 执行中的异常信息会保存在warnings中
List<String> warnings = new ArrayList<String>();
try {
// true:生成的文件覆盖之前的
boolean overwrite = true;
// 读取配置,构造 Configuration 对象.
// 如果不想使用配置文件的话,也可以直接来 new Configuration(),然后给相应属性赋值.
ClassPathResource classPathResource = new ClassPathResource("mybatis-generator-config.xml");
File configFile = classPathResource.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);
} catch (SQLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
} catch (InvalidConfigurationException e) {
e.printStackTrace();
} catch (XMLParserException e) {

}
for (String warning : warnings){
System.out.println(warning);
}
}
}
