本文主要讲述：使用jaxb完成对象和xml之间的转换

TestJava2xml.java如下所示：

package com.tgb.jaxb.v1;
    
    import java.io.StringReader;
    
    import javax.xml.bind.JAXBContext;
    import javax.xml.bind.JAXBException;
    import javax.xml.bind.Marshaller;
    import javax.xml.bind.Unmarshaller;
    
    import org.junit.Test;
    
    /**

    public class TestJava2xml {
    
    	// 测试：Java文件转化为Xml文件
    	@Test
    	public void testJava2Xml() {
    		try {
    			JAXBContext ctx = JAXBContext.newInstance(Student.class);
    			// 用于Java文件转化为Xml文件的类
    			Marshaller marshaller = ctx.createMarshaller();
    			Student student = new Student(1001, "赵栗婧", 20, new Classroom(10,
    					"10级生命科学与工程", 2010));
    			marshaller.marshal(student, System.out);
    
    		} catch (JAXBException e) {
    			e.printStackTrace();
    		}
    	}
    
    	// 测试Xml文件转化为Java文件
    	@Test

    		} catch (JAXBException e) {
    			e.printStackTrace();

    	}
    
    }
