Jaxb2 Transform XML Document--Complete Java object and XML conversion

This time, Jaxb2 completes the conversion of XML, JAXB2 uses the new features of JDK. such as: Annotation, GenericType and so on, Jaxb2 need to add Annotation annotation in the JavaBean that will be converted. Let's take a look at how Jaxb2 is completing the conversion of Java objects to XML.

First, preparatory work

1. Resource Preparation

A) official documents: http://www.oracle.com/technetwork/articles/javase/index-140168.html

b) Jar pack Download: Http://jaxb.java.net/2.2.3/JAXB2_20101209.jar

If you have a jar to add JDK to the project, there is a jaxb2 in the Rt.jar. In general, you do not need to add jaxb2 jars yourself.

2, code preparation before the program

Import Java.io.StringReader;

Import Java.io.StringWriter;

Import java.util.ArrayList;

Import Java.util.HashMap;

Import java.util.List;

Import Java.util.Map;

Import Javax.xml.bind.JAXBContext;

Import javax.xml.bind.JAXBException;

Import Javax.xml.bind.Marshaller;

Import Javax.xml.bind.Unmarshaller;

Import Org.junit.After;

Import Org.junit.Before;

Import Org.junit.Test;

Import Com.hoo.entity.Account;

Import Com.hoo.entity.AccountBean;

Import Com.hoo.entity.Birthday;

Import Com.hoo.entity.ListBean;

Import Com.hoo.entity.MapBean;
