Java Bean以及xsd相互生成

1.先定义一个Java bean  -- Student.java

 import java.util.List;
 public class Student {
     private String name;
     private String number;
     private String gender;
     private String age;
     private List<Course> courses;

     public static class Course {
         private String name;
         private String grade;
         private String remark;
                 // Getter and Setter Methods ...
     }
         // Getter and Setter Methods ...
 }

2.创建xsd文件生成的工具类 -- XSDCreate

 import java.io.File;
 import java.io.IOException;
 import javax.xml.bind.JAXBContext;
 import javax.xml.bind.JAXBException;
 import javax.xml.bind.SchemaOutputResolver;
 import javax.xml.transform.Result;
 import javax.xml.transform.stream.StreamResult;

 public class XSDCreate {

     public CustomSchemaOutputResolver resolver;

     public static void main(String[] args) {
         XSDCreate xsdCreate = new XSDCreate();
         xsdCreate.resolver = xsdCreate.new CustomSchemaOutputResolver("F:\\schema", "student.xsd");

         Class[] classes = { Student.class };
         xsdCreate.createXSD(classes);

         System.out.println("all done");
     }

     public void createXSD(Class[] classes) {
         try {
             JAXBContext context = JAXBContext.newInstance(classes);
             context.generateSchema(resolver);
         } catch (JAXBException e) {
             e.printStackTrace();
         } catch (IOException e) {
             e.printStackTrace();
         }
     }

     public class CustomSchemaOutputResolver extends SchemaOutputResolver {

         private File file;

         public CustomSchemaOutputResolver(String dir, String fileName) {
             try {
                 file = new File(dir, fileName);
                 if (!file.exists()) {
                     file.createNewFile();
                 }
             } catch (IOException e) {
                 e.printStackTrace();
             }
         }

         @Override
         public Result createOutput(String namespaceUri, String suggestedFileName) throws IOException {
             return new StreamResult(file);
         }

     }
 }

3. 运行XSDCreate的main方法 即可在 F:\\schema目录下生成Schema文件 --> student.xsd。

4. Window CMD 执行如下命令（JDK环境下的XJC 命令）：

    xjc student.xsd -d F:\schema -p com.bert.bean

    执行结果如下：
