本章將教你若何應用Struts2 的運用法式發送電子郵件。關於此演習中,須要下載並裝置將mail.jar 從 JavaMail API1.4.4,並將 mail.jar文件放置在WEB-INFlib文件夾,然後持續遵守的尺度步調創立舉措,視圖和設置裝備擺設文件。
創立舉措:
下一步是創立一個Action辦法,發送電子郵件。讓我們創立一個新類稱為 Emailer.java 以下內容。
package com.yiibai.struts2; import java.util.Properties; import javax.mail.Message; import javax.mail.PasswordAuthentication; import javax.mail.Session; import javax.mail.Transport; import javax.mail.internet.InternetAddress; import javax.mail.internet.MimeMessage; import com.opensymphony.xwork2.ActionSupport; public class Emailer extends ActionSupport { private String from; private String password; private String to; private String subject; private String body; static Properties properties = new Properties(); static { properties.put("mail.smtp.host", "smtp.gmail.com"); properties.put("mail.smtp.socketFactory.port", "465"); properties.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory"); properties.put("mail.smtp.auth", "true"); properties.put("mail.smtp.port", "465"); } public String execute() { String ret = SUCCESS; try { Session session = Session.getDefaultInstance(properties, new javax.mail.Authenticator() { protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(from, password); }}); Message message = new MimeMessage(session); message.setFrom(new InternetAddress(from)); message.setRecipients(Message.RecipientType.TO, InternetAddress.parse(to)); message.setSubject(subject); message.setText(body); Transport.send(message); } catch(Exception e) { ret = ERROR; e.printStackTrace(); } return ret; } public String getFrom() { return from; } public void setFrom(String from) { this.from = from; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getTo() { return to; } public void setTo(String to) { this.to = to; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getBody() { return body; } public void setBody(String body) { this.body = body; } public static Properties getProperties() { return properties; } public static void setProperties(Properties properties) { Emailer.properties = properties; } }
可以看到在下面的源代碼中,Emailer.java有對應的情勢鄙人面給出的email.jsp頁的屬性的屬性。這些屬性
我們有無斟酌過上述各個屬性的任何驗證,驗證將被添加鄙人一章。如今讓我們看看在execute()辦法。 execute()辦法應用應用javax郵件庫發送一封電子郵件,應用供給的參數。假如郵件被發送,舉措前往 SUCCESS,不然它前往ERROR。
創立主頁頁:
讓我們編寫主頁index.jsp的JSP文件,這將被用來搜集電子郵件的相干信息,下面提到的:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Email Form</title> </head> <body> <em>The form below uses Google's SMTP server. So you need to enter a gmail username and password </em> <form action="emailer" method="post"> <label for="from">From</label><br/> <input type="text" name="from"/><br/> <label for="password">Password</label><br/> <input type="password" name="password"/><br/> <label for="to">To</label><br/> <input type="text" name="to"/><br/> <label for="subject">Subject</label><br/> <input type="text" name="subject"/><br/> <label for="body">Body</label><br/> <input type="text" name="body"/><br/> <input type="submit" value="Send Email"/> </form> </body> </html>
創立視圖:
我們將應用JSP文件的success.jsp將被挪用的情形下行為前往SUCCESS,但在產生ERROR 的情形下,我們將有另外一種視圖以為文件是從操作前往。
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Email Success</title> </head> <body> Your email to <s:property value="to"/> was sent successfully. </body> </html>
上面將是在一個毛病的情形下,從舉措前往視圖文件error.jsp。
<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%> <%@ taglib prefix="s" uri="/struts-tags"%> <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>Email Error</title> </head> <body> There is a problem sending your email to <s:property value="to"/>. </body> </html>
設置裝備擺設文件:
如今,讓我們將這一切組合起來應用struts.xml的設置裝備擺設文件以下:
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN" "http://struts.apache.org/dtds/struts-2.0.dtd"> <struts> <constant name="struts.devMode" value="true" /> <package name="helloworld" extends="struts-default"> <action name="emailer" class="com.yiibai.struts2.Emailer" method="execute"> <result name="success">/success.jsp</result> <result name="error">/error.jsp</result> </action> </package> </struts>
以下是web.xml文件中的內容:
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0"> <display-name>Struts 2</display-name> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <filter> <filter-name>struts2</filter-name> <filter-class> org.apache.struts2.dispatcher.FilterDispatcher </filter-class> </filter> <filter-mapping> <filter-name>struts2</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> </web-app>
如今,右鍵點擊項目稱號,並單擊 Export > WAR File創立一個WAR文件。然後安排此WAR在Tomcat的webapps目次下。最初,啟動Tomcat辦事器和測驗考試拜訪URL http://localhost:8080/HelloWorldStruts2/index.jsp。這會給出以下畫面:
輸出所需信息,並單擊“Send Email ”按鈕。假如一切順遂,那末應當看到以下頁面:
假如是SSH三個框架合營起來應用,這裡再給個例子,不外struts和spring的框架外,也須要mail.jar,activation.jar.
1) 起首在applicationContext.xml文件中設置裝備擺設bean
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="host"/> <property name="username" value="username"/> <property name="password" value="password"/> </bean> <bean id="sendMailAction" class="cn.com.action.SendMailAction" singleton="false"> <property name="mailSender"><ref bean="mailSender"/> </property> </bean>
2)完成發送郵件java類代碼
protected JavaMailSenderImpl mailSender; public class SendMailAction extends ActionSupport{ public void setMailSender(JavaMailSenderImpl mailSender) { this.mailSender = mailSender; } public void sendMail() throws Exception {
1:簡略郵件
protected JavaMailSenderImpl mailSender; public class SendMailAction extends ActionSupport{ public void setMailSender(JavaMailSenderImpl mailSender) { this.mailSender = mailSender; } public void sendMail() throws Exception {
2:HTML郵件的發送
//樹立郵件新聞,發送簡略郵件和html郵件的差別 MimeMessage mailMessage = senderImpl.createMimeMessage(); MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage); //設置收件人,寄件人 messageHelper.setTo("[email protected]"); messageHelper.setFrom("[email protected]"); messageHelper.setSubject("測試HTML郵件!"); //true 表現啟動HTML格局的郵件 messageHelper.setText("<html><head></head><body><h1>hello!!zhangjian</h1></body></html>",true); //發送郵件 senderImpl.send(mailMessage);
3:本類測試郵件中嵌套圖片
//樹立郵件新聞,發送簡略郵件和html郵件的差別 MimeMessage mailMessage = senderImpl.createMimeMessage(); //留意這裡的boolean,等於真的時刻能力嵌套圖片,在構建MimeMessageHelper時刻,所給定的值是true表現啟用, multipart形式 MimeMessageHelper messageHelper = new MimeMessageHelper(mailMessage,true); //設置收件人,寄件人 messageHelper.setTo("[email protected]"); messageHelper.setFrom("[email protected]"); messageHelper.setSubject("測試郵件中嵌套圖片!!"); //true 表現啟動HTML格局的郵件 messageHelper.setText("<html><head></head><body><h1>hello!!zhangjian</h1>" + "<img src="/" mce_src="/""cid:aaa/"/></body></html>",true); FileSystemResource img = new FileSystemResource(new File("c:/aaa.jpg")); messageHelper.addInline("aaa",img); //發送郵件 senderImpl.send(mailMessage); } }
