java實現系統捕獲異常發送郵件案例

在實際運用中，比如你淘寶購物，申請退款，這時你在郵箱中看到退款郵件，或者你註冊某個賬號，申請驗證郵箱通知等等，這些都是郵件發送，這裡將介紹下系統捕獲異常發送郵件案例。

準備工作：
eclipse4.5 64位
jdk1.7 64位

郵件發送所需jar：

fastjson-1.1.24.jar，javax.mail-1.5.6.jar

類Developer：

枚舉類型，發送郵件人姓名和郵箱地址

package mail; /** * @class:Developer *@descript:枚舉類型，發送郵件人姓名和郵箱地址*@date:2016年10月26日下午8:07:50 *@author sanghaiqin *@version:V1.0 */ public enum Developer { zhoujing("周靜","[email protected]"), peiyuxiang("裴玉翔","[email protected]"), yipeng("乙鵬","[email protected]"), liuan("劉安","[email protected]"), chenyuhao("陳宇豪","[email protected]"), wangdong("王棟","[email protected]"), sanghaiqin("桑海芹","[email protected]"); //發件人姓名private String name; //發件人email private String mail; private Developer() { } private Developer(String name, String mail) { this.name = name; this.mail = mail; } /** * @descript:傳遞發件人姓名得到該發件人的郵箱* @param name 發件人姓名* @return */ public static String getMail(String name) { for (Developer c : Developer.values()) { if (c.getName().equals(name)) { return c.mail; } } return null; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getMail() { return mail; } public void setMail(String mail) { this.mail = mail; } }

類ExceptionInfo：發件人信息

package mail; /** * @class:ExceptionInfo *@descript:發件人信息*@date:2016年10月26日下午8:11:27 *@author sanghaiqin *@version:V1.0 */ public class ExceptionInfo { //發件人姓名private String developer; //發件人方法private String method; //發件人url private String url; //發件人捕獲異常信息private Exception e; /** * @param developer 發件人姓名* @param method 發件人方法* @param url 發件人url * @param e 發件人捕獲異常信息*/ public ExceptionInfo(String developer, String method, String url, Exception e) { super(); this.developer = developer; this.method = method; this.url = url; this.e = e; } public String getDeveloper() { return developer; } public void setDeveloper(String developer) { this.developer = developer; } public String getMethod() { return method; } public void setMethod(String method) { this.method = method; } public String getUrl() { return url; } public void setUrl(String url) { this.url = url; } public Exception getE() { return e; } public void setE(Exception e) { this.e = e; } }

類MailSenderInfo：發送郵箱信息

package mail; import java.util.Properties; /** * @class:MailSenderInfo *@descript:發送郵箱信息*@date:2016年10月26日下午8:14:22 *@author sanghaiqin *@version:V1.0 */ public class MailSenderInfo { //發送郵件的服務器的IP private String mailServerHost; //發送郵件的服務器的端口默認為25 private String mailServerPort = "25"; // 郵件發送者的地址private String fromAddress; // 郵件接收者的地址private String toAddress; // 登陸郵件發送服務器的用戶名private String username; // 登陸郵件發送服務器的密碼private String password; // 是否需要身份驗證private boolean validate = false; // 郵件主題private String subject; // 郵件的文本內容private String content; // 郵件附件的文件名private String[] attachFileNames; public MailSenderInfo() { super(); } public String getMailServerHost() { return mailServerHost; } public void setMailServerHost(String mailServerHost) { this.mailServerHost = mailServerHost; } public String getMailServerPort() { return mailServerPort; } public void setMailServerPort(String mailServerPort) { this.mailServerPort = mailServerPort; } public boolean isValidate() { return validate; } public void setValidate(boolean validate) { this.validate = validate; } public String[] getAttachFileNames() { return attachFileNames; } public void setAttachFileNames(String[] fileNames) { this.attachFileNames = fileNames; } public String getFromAddress() { return fromAddress; } public void setFromAddress(String fromAddress) { this.fromAddress = fromAddress; } public String getPassword() { return password; } public void setPassword(String password) { this.password = password; } public String getToAddress() { return toAddress; } public void setToAddress(String toAddress) { this.toAddress = toAddress; } public String getUsername() { return username; } public void setUsername(String username) { this.username = username; } public String getSubject() { return subject; } public void setSubject(String subject) { this.subject = subject; } public String getContent() { return content; } public void setContent(String textContent) { this.content = textContent; } /** * @descript:獲得郵件會話屬性* @return */ public Properties getProperties() { PropertyUtil propertyUtil = new PropertyUtil(); Properties properties =propertyUtil.readProperties(); return properties; } }

類MyAuthenticator：用戶驗證

package mail; import javax.mail.Authenticator; import javax.mail.PasswordAuthentication; /** * @class:MyAuthenticator *@descript:用戶驗證*@date:2016年10月26日下午8:57:45 *@author sanghaiqin *@version:V1.0 */ public class MyAuthenticator extends Authenticator { //用戶名String username = null; //密碼String password = null; public MyAuthenticator() { } public MyAuthenticator(String username, String password) { this.username = username; this.password = password; } protected PasswordAuthentication getPasswordAuthentication() { return new PasswordAuthentication(username, password); } }

類PropertyUtil：獲得properties文件工具類

package mail; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.io.IOException; import java.io.InputStream; import java.util.Properties; /** * @class:PropertyUtil *@descript:獲得properties文件工具類*@date:2016年10月26日下午8:20:10 *@author sanghaiqin *@version:V1.0 */ public class PropertyUtil { /** * @descript:加載資源文件* @param resources 資源文件* @return * @throws FileNotFoundException */ private Properties loadProperties(String resources) { InputStream inputstream = null; Properties properties = new Properties(); // 使用InputStream得到一個資源文件try { inputstream = new FileInputStream(resources); // 加載配置文件properties.load(inputstream); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); }finally{ if(inputstream!=null){ try { inputstream.close(); } catch (IOException e) { e.printStackTrace(); } } } return properties; } /** * @descript:讀屬性文件* @return * @throws FileNotFoundException */ public Properties readProperties(){ String resources = PropertyUtil.class.getClassLoader().getResource("prop.properties").getPath(); Properties properties = loadProperties(resources); return properties; } /** * @descript：測試* @param args */ public static void main(String[] args) { PropertyUtil p=new PropertyUtil(); Properties pro=p.readProperties(); String mailSenderUsername=(String) pro.get("mail.sender.username"); System.out.println("郵件發送者用戶名："+mailSenderUsername);//[email protected] String path = PropertyUtil.class.getClassLoader().getResource("prop.properties").getPath(); System.out.println(path);// /G:/Workspaces4.4/test/bin/prop.properties } }

資源文件pro.properties：

 #-------------------郵件功能------------------ #----------------這兩個是構建session必須的字段---------- #smtp服務器，構建session回話必須的字段mail.smtp.host=smtp.163.com #身份驗證，構建session回話必須的字段mail.smtp.auth=true #-------------------------------------------------------------- #發送者的郵箱用戶名[email protected] #發送者的郵箱密碼mail.sender.password=827623LIU #發送者的郵箱地址[email protected]
