2.在src/main/java中包com.iteye.xujava.account.persist下创建以下四个Java文件

package com.iteye.xujava.account.persist;

public class Account {

	private String id;
	private String name;
	private String email;
	private String password;
	private boolean activated;

	public String getId() {
		return id;
	}

	public void setId(String id) {
		this.id = id;
	}

	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getEmail() {
		return email;
	}

	public void setEmail(String email) {
		this.email = email;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	public boolean isActivated() {
		return activated;
	}

	public void setActivated(boolean activated) {
		this.activated = activated;
	}

}

  

package com.iteye.xujava.account.persist;

public class AccountPersistException extends Exception {

	private static final long serialVersionUID = 7208989305935509389L;

	public AccountPersistException(String message) {
		super(message);
	}

	public AccountPersistException(String message, Throwable throwable) {
		super(message, throwable);
	}
}

package com.iteye.xujava.account.persist;

public interface AccountPersistService {

	Account createAccount(Account account) throws AccountPersistException;

	Account readAccount(String id) throws AccountPersistException;

	Account updateAccount(Account account) throws AccountPersistException;

	void deleteAccount(String id) throws AccountPersistException;
}

package com.iteye.xujava.account.persist;

import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.util.List;

import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.DocumentFactory;
import org.dom4j.Element;

public class AccountPersistServiceImpl implements AccountPersistService {

	private String file;
	private SAXReader reader = new SAXReader();

	private static final String ELEMENT_ROOT = "account-persist";
	private static final String ELEMENT_ACCOUNTS = "accounts";
	private static final String ELEMENT_ACCOUNT = "account";

	public Account createAccount(Account account) throws AccountPersistException {
		Document doc = readDocument();

		Element accountsEle = doc.getRootElement().element(ELEMENT_ACCOUNTS);

		accountsEle.add(buildAccountElement(account));

		writeDocument(doc);

		return account;
	}

	@SuppressWarnings("unchecked")
	public Account readAccount(String id) throws AccountPersistException {
		Document doc = readDocument();
		Element accountsEle = doc.getRootElement().element(ELEMENT_ACCOUNTS);
		for (Element accountEle : (List<Element>) accountsEle.elements()) {
			if (accountEle.elementText(ELEMENT_ACCOUNT_ID).equals(id)) {
				return buildAccount(accountEle);
			}
		}
		return null;
	}

	public Account updateAccount(Account account) throws AccountPersistException {
		if (readAccount(account.getId()) != null) {
			deleteAccount(account.getId());

			return createAccount(account);
		}

		return null;
	}

	@SuppressWarnings("unchecked")
	public void deleteAccount(String id) throws AccountPersistException {

		Element accountsEle = doc.getRootElement().element(ELEMENT_ACCOUNTS);

		for (Element accountEle : (List<Element>) accountsEle.elements()) {
			if (accountEle.elementText(ELEMENT_ACCOUNT_ID).equals(id)) {
				accountEle.detach();

				writeDocument(doc);

				return;
			}
		}
	}

	private Account buildAccount(Element element) {
		Account account = new Account();
		account.setId(element.elementText(ELEMENT_ACCOUNT_ID));
		account.setName(element.elementText(ELEMENT_ACCOUNT_NAME));
		account.setEmail(element.elementText(ELEMENT_ACCOUNT_EMAIL));
		account.setPassword(element.elementText(ELEMENT_ACCOUNT_PASSWORD));
		account.setActivated(element.elementText(ELEMENT_ACCOUNT_ACTIVATED).equals("true") ? true : false);

		return account;
	}

	private Element buildAccountElement(Account account) {
		Element element = DocumentFactory.getInstance().createElement(ELEMENT_ACCOUNT);

		element.addElement(ELEMENT_ACCOUNT_ID).setText(account.getId());
		element.addElement(ELEMENT_ACCOUNT_NAME).setText(account.getName());

		element.addElement(ELEMENT_ACCOUNT_PASSWORD).setText(account.getPassword());
		element.addElement(ELEMENT_ACCOUNT_ACTIVATED).setText(account.isActivated() ? "true" : "false");

		return element;
	}

	private Document readDocument() throws AccountPersistException {
		File dataFile = new File(file);
		if (!dataFile.exists()) {
			dataFile.getParentFile().mkdirs();
			Document doc = DocumentFactory.getInstance().createDocument();
			Element rootEle = doc.addElement(ELEMENT_ROOT);
			rootEle.addElement(ELEMENT_ACCOUNTS);
			writeDocument(doc);
		}
		try {
			return reader.read(new File(file));
		} catch (DocumentException e) {
			throw new AccountPersistException("不能读取xml文件", e);
		}
	}

	private void writeDocument(Document doc) throws AccountPersistException {
		Writer out = null;
		try {
			out = new OutputStreamWriter(new FileOutputStream(file), "UTF-8");

					out.close();
				}
			} catch (IOException e) {

			}
		}
	}

	public String getFile() {
		return file;
	}

	public void setFile(String file) {
		this.file = file;
	}

}

3.在src/main/resources目录下创建以下两个文件

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">

	<bean id="propertyConfigurer"
		class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
		<property name="location" value="classpath:service.properties" />
	</bean>

	<bean id="accountPersistService"
		class="com.iteye.xujava.account.persist.AccountPersistServiceImpl">
		<property name="file" value="${persist.file}" />
	</bean>

</beans>

  

persist.file=E:/mavenspace/account-persist/target/test-classes/persist-data.xml

4.在src/test/java中包com.iteye.xujava.account.persist下创建

package com.iteye.xujava.account.persist;

import static org.junit.Assert.*;

import java.io.File;

import org.junit.Before;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AccountPersistServiceTest
{
	private AccountPersistService service;
	
	@Before
	public void prepare()
		throws Exception
	{
		File persistDataFile = new File ( "target/test-classes/persist-data.xml" );
		
		if ( persistDataFile.exists() )
		{
			persistDataFile.delete();
		}
		
		ApplicationContext ctx = new ClassPathXmlApplicationContext( "account-persist.xml" );

		service = (AccountPersistService) ctx.getBean( "accountPersistService" );
    	
    	Account account = new Account();
    	account.setId("xuj");
    	account.setName("Xuj");
    	account.setEmail("[email protected]");
    	account.setPassword("this_should_be_encrypted");
    	account.setActivated(true);
    	
    	service.createAccount(account);
	}
	
    @Test
    public void testReadAccount()
        throws Exception
    {
        Account account = service.readAccount( "xuj" );

        assertNotNull( account );
        assertEquals( "xuj", account.getId() );
        assertEquals( "Xuj", account.getName() );
        assertEquals( "[email protected]", account.getEmail() );
        assertEquals( "this_should_be_encrypted", account.getPassword() );
        assertTrue( account.isActivated() );
    }

    @Test
    public void testDeleteAccount()
        throws Exception
    {
        assertNotNull( service.readAccount( "xuj" ) );
        service.deleteAccount( "xuj" );
        assertNull( service.readAccount( "xuj" ) );
    }
    
    @Test
    public void testCreateAccount()
    	throws Exception
    {
    	assertNull( service.readAccount( "mike" ) );
    	
    	Account account = new Account();
    	account.setId("mike");
    	account.setName("Mike");
    	account.setEmail("[email protected]");
    	account.setPassword("this_should_be_encrypted");
    	account.setActivated(true);
    	
    	service.createAccount(account);
    	
    	assertNotNull( service.readAccount( "mike" ));
    }
    
    @Test
    public void testUpdateAccount()
    	throws Exception
    {
    	Account account = service.readAccount( "xuj" );
    	
    	account.setName("Xuj 1");
    	account.setEmail("[email protected]");
    	account.setPassword("this_still_should_be_encrypted");
    	account.setActivated(false);
    	
    	service.updateAccount( account );
    	
    	account = service.readAccount( "xuj" );
    	
        assertEquals( "Xuj 1", account.getName() );
        assertEquals( "[email protected]", account.getEmail() );
        assertEquals( "this_still_should_be_encrypted", account.getPassword() );
        assertFalse( account.isActivated() );
    }
}

5.运行mvn clean test

6.运行mvn clean install
