任务
-
异步任务
-
定时任务
-
邮件任务
一、异步任务
-
编写任务类
@Service
public class AsyncService {
@Async//异步注解
public void hello(){
try {
Thread.sleep(3000);
} catch (InterruptedException e) {
e.printStackTrace();
}
System.out.println("数据正在处理中");
}
}
-
调用任务类
@RestController
public class AsyncController {
@Autowired
AsyncService asyncService;
@RequestMapping("/hello")
public String hello(){
asyncService.hello();
return "OK";
}
}
-
开启异步注解
@SpringBootApplication
@EnableScheduling //开启定时任务
@EnableAsync //开启异步任务
public class Springboot06SecurityApplication {
public static void main(String[] args) {
SpringApplication.run(Springboot06SecurityApplication.class, args);
}
}

二、邮件任务
1.javaSE
导包
<!--mail-->
<dependency>
<groupId>javax.activation</groupId>
<artifactId>activation</artifactId>
<version>1.1.1</version>
</dependency>
<dependency>
<groupId>javax.mail</groupId>
<artifactId>mail</artifactId>
<version>1.4.7</version>
</dependency>
@Test
void contextLoads() throws GeneralSecurityException, MessagingException {
//1.设置QQ邮件服务器，邮件发送协议，验证用户名密码
// 创建Properties 类用于记录邮箱的一些属性
Properties props = new Properties();
// 表示SMTP发送邮件，必须进行身份验证
props.put("mail.smtp.auth", "true");
//此处填写SMTP服务器
props.put("mail.smtp.host", "smtp.qq.com");
//端口号，QQ邮箱端口号
props.put("mail.smtp.port", "587");
// 此处填写你的账号
props.put("mail.user", "qq@qq.com");
// 此处的密码就是前面说的16位STMP口令
props.put("mail.password", "授权码");
// 2.构建授权信息，用于进行SMTP进行身份验证
Authenticator authenticator = new Authenticator() {
protected PasswordAuthentication getPasswordAuthentication() {
// 用户名、密码
String userName = props.getProperty("mail.user");
String password = props.getProperty("mail.password");
return new PasswordAuthentication(userName, password);
}
};
//3. 使用环境属性和授权信息，创建邮件会话
Session mailSession = Session.getInstance(props, authenticator);
//4. 创建邮件消息
MimeMessage message = new MimeMessage(mailSession);
// 设置发件人
InternetAddress form = new InternetAddress(props.getProperty("mail.user"));
message.setFrom(form);
// 设置收件人的邮箱
InternetAddress to = new InternetAddress("qq@qq.com");
message.setRecipient(Message.RecipientType.TO, to);
// 设置邮件标题
message.setSubject("请点击以下链接激活您的邮箱");
// 设置邮件的内容体
message.setContent("<html lang='zh-CN'><head ><meta charset='utf-8'>"
+ "</head><body>您好，欢迎订阅Victoria，请点击以下链接确认激活您的邮箱！<br><br>"
+ "</body></html>",
"text/html;charset=utf-8");
//5. 发送邮件
Transport.send(message);
}
2.SpringBoot之邮箱任务
-
导包
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>
-
编写配置文件
spring.mail.username=644037316@qq.com
spring.mail.password=rxxgbgjdzzyebahe
spring.mail.host=smtp.qq.com
#开启加密验证
spring.mail.properties.mail.smtp.ssl.enable=ture
3.编写任务类
//简单的邮件
@Autowired
JavaMailSenderImpl mailSender;
@Test
void contextLoads() {
SimpleMailMessage mailMessage = new SimpleMailMessage();
mailMessage.setSubject("邮箱任务");
mailMessage.setText("SpringBoot之邮箱任务");
mailMessage.setTo("644037316@qq.com");
mailMessage.setFrom("644037316@qq.com");
mailSender.send(mailMessage);
}
//复杂的邮件
@Test
void contextLoads2() throws MessagingException {
MimeMessage mimeMessage = mailSender.createMimeMessage();
MimeMessageHelper helper = new MimeMessageHelper(mimeMessage,true);
helper.setSubject("复杂的邮件任务");
helper.setText("SpringBoot之邮件任务",true);
helper.addAttachment("1.png",new File("C:\\Users\\Administrator\\Pictures\\1.png"));
helper.setTo("644037316@qq.com");
helper.setFrom("644037316@qq.com");
mailSender.send(mimeMessage);
}
3.定时任务
-
编写一个任务类
@Controller\\加到容器里
public class ScheduledController {
// 秒 分 时 日 月 周
@Scheduled(cron = "0/10 * * * * ?")//每隔10秒执行一次
public void hello(){
System.out.println("Hello,SpringBoot之定时任务");
}
}
-
开启定时任务
@SpringBootApplication
@EnableScheduling //开启定时任务
public class Springboot06SecurityApplication {
public static void main(String[] args) {
SpringApplication.run(Springboot06SecurityApplication.class, args);
}
}
-
