}2.6电子有点发送工具类
public class EmailUtils {
public static void sendEmail(String title,String content,String receiveAccount){
String myAccount = "498414698@qq.com";
//发件人 邮箱的 SMTP 服务器地址
//String SMTPHost = "smtp.163.com";//163
String SMTPHost = "smtp.qq.com";//qq
//组成 properties
Properties prop = new Properties();
prop.setProperty("mail.transport.protocol", "smtp");//设置协议类型
prop.setProperty("mail.smtp.host", SMTPHost);//定义发件人的邮箱服务器地址
prop.setProperty("mail.smtp.auth", "true");//设置请求验证
//1.Session对象 创建会话 用于和邮箱服务器进行交互
Session session = Session.getDefaultInstance(prop);
//设置debug模式 可以查看详细发送信息 可略
session.setDebug(true);
//2.创建方法 用来组成一封完整的邮件
//参数 session(参数配置), myAccount 发送方 , user.getEmail() 接收方
//使用session对象 获取待发送的邮件信息
MimeMessage message = new MimeMessage(session);
//3.设置发件人 收件人 标题 邮件内容 附件 发送时间等等
try {
//3.1发件人 from
message.setFrom(new InternetAddress(myAccount, "小米", "utf-8"));
//3.2收件人 to 支持可以添加多个收件人 | 抄送 | 密送 如果想要发送给多个人 可以重复下面代码多次
/*
* MimeMessage.RecipientType.TO 发送
* MimeMessage.RecipientType.CC 抄送
* MimeMessage.RecipientType.BCC 密送
* */
message.setRecipient(MimeMessage.RecipientType.TO, new InternetAddress(receiveAccount, "utf-8"));
//3.3生成邮件主题
message.setSubject(title,"utf-8");
String ip = Inet4Address.getLocalHost().getHostAddress();//本机ip地址
//www.xiaomi.com
//String url = "http://"+ip+":8080/activate?c=");
//message.setText(content); 普通文本
//设置邮件正文 setContent 可以使用html标签
message.setContent(content,"text/html;charset=utf-8");
//设置邮件的发送时间 是立即发送
//message.setSentDate(new Date());
//保存设置
message.saveChanges();
//4.利用Transport 发送邮件
Transport tran = session.getTransport();
//连接服务器 确认发送方 是否授权
tran.connect(myAccount,"papawrgiguwdbjaj" );
//发送邮件 将message 对象 传给 Transport 对象 将邮件发送出去
//参数1 要发的内容 参数2 要给哪些人发
//message.getAllRecipients() 获取到所有的收件人 | 抄送 | 密送
tran.sendMessage(message, message.getAllRecipients());
//关闭连接
tran.close();
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
public static void main(String[]args) throws Exception{
// sendEmail("哈喽","你好","498414698@qq.com");
System.out.println(Inet4Address.getLocalHost().getHostAddress());
}
}2.7参数的工具类
public class SysConstant {
public enum Status{
NOT_ACTIVE(0),ACTIVE(1);
int code ;
Status(int code){
this.code = code;
}
public int getCode(){
return code;
}
}
public static final int NOT_ACTIVE=0;
public static final int CUSTOMER=0;
public static final String FORWARD="forward";
public static final String REDIRECT="redirect";
public static final String FLAG=":";
//订单状态 0 未付款，1已经付款未发货 2发货待收货 3 收货待评价 4订单完成 5 退货状态
}3.BaseController（Servlet）
public class BaseController extends HttpServlet {
@Override
protected void service(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
//得到method（controller对应的方法名）
String method = request.getParameter("method");
if(method==null){
//转去首页
response.sendRedirect("/login.jsp");
}
try {
//得到对象
Class class1 = this.getClass();
Object o = class1.newInstance();
//得到要处理业务的方法：比如说：login
Method loginMethod = class1.getMethod(method,HttpServletRequest.class,HttpServletResponse.class);
//设置 Content-type实体报头。
//一般在Servlet中，习惯性的会首先设置请求以及响应的内容类型以及编码方式：
if (loginMethod.isAnnotationPresent(ContentType.class)){
ContentType contentType = loginMethod.getAnnotation(ContentType.class);
String type = contentType.value();//image/jpeg application/json;charset=utf-8
response.setContentType(type);
}else{
response.setContentType("text/html;charset=utf-8");
}
//调用方法
Object invoke = loginMethod.invoke(o, request, response);
//如果有返回值如 return "forward:index.jsp"
if(invoke!=null){
//返回值是String类型---->跳转页面（转发、重定向）
if(invoke.getClass().getSimpleName().equalsIgnoreCase("String")){
String s = (String) invoke;
//得到页面的字符串
String substring = s.substring(s.indexOf(":") + 1);
if(s.startsWith(SysConstant.FORWARD)){
request.getRequestDispatcher(substring).forward(request, response);
// request.getRequestDispatcher("/test001.jsp").forward(request, response);
}else{
response.sendRedirect(substring);
}
}else{
//需要转json数据
String s = new Gson().toJson(invoke);
response.getWriter().print(s);
}
}
} catch (Exception e) {
e.printStackTrace();
}
}
}4.1运行流程一：
1.登陆–>
1.登陆–>2.主页
4.2运行流程二：
1.注册–>
1.注册–>2.注册页面
1.注册–>2.注册页面–>3.（注册完点击提交到）激活界面
1.注册–>2.注册页面–>3.（注册完点击提交到）激活界面–>点击激活链接可以到邮箱界面，从接收到的邮件里面点击立即激活 / 或者自己打开邮箱，从接收到的邮件里面点击立即激活
在写邮件工具类的时候，里面会有一个授权码，这个授权码需要在自己邮箱里面得到，每条1分钱
