Spring实现Email功能

1，applicationContext.xml

 

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xsi:schemaLocation="
   http://www.springframework.org/schema/beans 
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context      
   http://www.springframework.org/schema/context/spring-context-3.0.xsd">

	<context:property-placeholder location="mail.properties" />

	<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
		<property name="host" value="${mail.host}" />
		<property name="username" value="${mail.username}" />
		<property name="password" value="${mail.password}" />
	</bean>

	<bean id="templateMessage" class="org.springframework.mail.SimpleMailMessage">
		<property name="from" value="${mail.username}" />
	</bean>

	<bean id="orderManager"
		class="ivan.test.email.springemail.action.impl.SimpleOrderManager">
		<property name="mailSender" ref="mailSender" />
		<property name="templateMessage" ref="templateMessage" />
	</bean>
</beans>

 2，实体类Order

package ivan.test.email.springemail.entity;


public class Order {

	private Customer customer;
	private int orderNumber;
	private String subject;

	public Customer getCustomer() {
		return customer;
	}

	public void setCustomer(Customer customer) {
		this.customer = customer;
	}

	public int getOrderNumber() {
		return orderNumber;
	}

	public void setOrderNumber(int orderNumber) {
		this.orderNumber = orderNumber;
	}

	public String getSubject() {
		return subject;
	}

	public void setSubject(String subject) {
		this.subject = subject;
	}

	
}

 3，实体类Customer

package ivan.test.email.springemail.entity;

public class Customer {
	private String firstName;
	private String lastName;
	private String emailAddress;

	public String getFirstName() {
		return firstName;
	}

	public void setFirstName(String firstName) {
		this.firstName = firstName;
	}

	public String getLastName() {
		return lastName;
	}

	public void setLastName(String lastName) {
		this.lastName = lastName;
	}

	public String getEmailAddress() {
		return emailAddress;
	}

	public void setEmailAddress(String emailAddress) {
		this.emailAddress = emailAddress;
	}

}

 4，发邮件接口

package ivan.test.email.springemail.action;

import ivan.test.email.springemail.entity.Order;

public interface OrderManager {
	void placeOrder(Order order);
}

 5，发邮件实现类

package ivan.test.email.springemail.action.impl;

import ivan.test.email.springemail.action.OrderManager;
import ivan.test.email.springemail.entity.Order;

import org.springframework.mail.MailException;
import org.springframework.mail.MailSender;
import org.springframework.mail.SimpleMailMessage;

public class SimpleOrderManager implements OrderManager {
	private MailSender mailSender;
	private SimpleMailMessage templateMessage;

	public void placeOrder(Order order) {
		SimpleMailMessage msg = new SimpleMailMessage(this.templateMessage);
		msg.setTo(order.getCustomer().getEmailAddress());
		msg.setText("Dear" + order.getCustomer().getFirstName()
				+ order.getCustomer().getLastName()
				+ ", thank you for placing order. Your order number is"
				+ order.getOrderNumber());
		msg.setSubject(order.getSubject());
		try {
			this.mailSender.send(msg);
		} catch (MailException ex) {
			System.err.println(ex.getMessage());
		}
	}

	public void setMailSender(MailSender mailSender) {
		this.mailSender = mailSender;
	}

	public void setTemplateMessage(SimpleMailMessage templateMessage) {
		this.templateMessage = templateMessage;
	}
}

 6，测试类

package ivan.test.email.springemail;

import ivan.test.email.springemail.action.OrderManager;
import ivan.test.email.springemail.entity.Customer;
import ivan.test.email.springemail.entity.Order;

import javax.annotation.Resource;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = { "/applicationContext.xml" })
public class SimpleOrderManagerTest {
	@Resource
	private OrderManager orderManager;

	@Test
	public void test() {
		Order order = new Order();
		Customer customer = new Customer();
		customer.setEmailAddress("[e-mail]");
		customer.setFirstName("Ivan");
		customer.setLastName("Zero");
		order.setCustomer(customer);
		order.setOrderNumber(10011);
		order.setSubject("My Order");

		orderManager.placeOrder(order);
	}
}
