二十九 SpringBoot整合Email
以下演示的是简单邮件发送
29.1 加入相关依赖
1 <dependency> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-web</artifactId> 4 </dependency> 5 6 <!-- Email依赖 --> 7 <dependency> 8 <groupId>org.springframework.boot</groupId> 9 <artifactId>spring-boot-starter-mail</artifactId> 10 </dependency> 11 12 <!-- freemarker的依赖 --> 13 <dependency> 14 <groupId>org.springframework.boot</groupId> 15 <artifactId>spring-boot-starter-freemarker</artifactId> 16 </dependency>
29.2 在全局配置文件中配置相关属性
1 spring.mail.host=smtp.qq.com 2 [email protected] 3 #授权码 4 spring.mail.password= 5 spring.mail.properties.mail.smtp.auth=true 6 spring.mail.properties.mail.smtp.starttls.enable=true 7 spring.mail.properties.mail.smtp.starttls.required=true
29.3 service层
1 package com.wu.service; 2 3 import java.io.File; 4 5 public interface EmailService { 6 //发送简单的邮件 7 public void sendSimpleEmailService(String sendTo,String title,String content); 8 9 //发送带有附件的邮件 10 public void sendAttachmentMail(String sendTo,String title,String content,File file); 11 12 //发送模板邮件 13 public void sendTemplateEmailService(String sendTo,String title,String content); 14 }

29.4 controller层
1 package com.wu.controller; 2 3 import java.io.File; 4 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.web.bind.annotation.RequestMapping; 7 import org.springframework.web.bind.annotation.RestController; 8 import com.wu.service.EmailService; 9 10 @RestController 11 public class EmailController { 12 @Autowired 13 private EmailService service; 14 15 //发送简单邮件 16 @RequestMapping("/sendSimpleEmail") 17 public String sendSimpleEmail(){ 18 service.sendSimpleEmailService("[email protected]","这是一个测试","请忽略！"); 19 return "success"; 20 } 21 22 //发送带有附件的邮件 23 @RequestMapping("/sendAttachmentEmail") 24 public String sendAttachmentEmail(){ 25 File file=new File("src/main/resources/static/test.txt"); 26 service.sendAttachmentMail("[email protected]","这也是一个测试","请忽略",file); 27 return "success again"; 28 } 29 30 //发送模板邮件 31 @RequestMapping("/sendTemplateEmailService") 32 public String sendTemplateEmailService(){ 33 service.sendTemplateEmailService("[email protected]","这是模板邮件","info.html"); 34 return "success again again"; 35 } 36 }
三十 SpringBoot实现文件上传
30.1 相关依赖
1 <dependency> 2 <groupId>org.springframework.boot</groupId> 3 <artifactId>spring-boot-starter-web</artifactId> 4 </dependency> 5 6 <!-- Thymeleaf模板 --> 7 <dependency> 8 <groupId>org.springframework.boot</groupId> 9 <artifactId>spring-boot-starter-thymeleaf</artifactId> 10 </dependency>
30.2 相关配置
1 #单个文件大小 2 multipart.maxFileSize=50Mb 3 #接收的所有文件大小 4 multipart.maxRequestSize=500Mb
30.3 Thymeleaf上传文件
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="UTF-8"/> 5 <title>上传文件</title> 6 </head> 7 <body> 8 <p>单个文件上传</p> 9 <form action="/upload" enctype="multipart/form-data" method="post"> 10 <input type="file" name="file"/><br></br> 11 <input type="submit" value="提交"/> 12 </form> 13 <hr></hr> 14 <p>批量文件上传</p> 15 <form action="/uploads" enctype="multipart/form-data" method="post"> 16 <input type="file" name="file"/><br></br> 17 <input type="file" name="file"/><br></br> 18 <input type="file" name="file"/><br></br> 19 <input type="submit" value="提交"/> 20 </form> 21 </body> 22 </html>
