1.在pom.xml中添加Maven 依赖:

<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-mail</artifactId>
</dependency>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-thymeleaf</artifactId>
</dependency>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-web</artifactId>
</dependency>

<dependency>
   <groupId>org.projectlombok</groupId>
   <artifactId>lombok</artifactId>
   <optional>true</optional>
</dependency>
<dependency>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-starter-test</artifactId>
   <scope>test</scope>
</dependency>

<dependency>
   <groupId>net.sourceforge.nekohtml</groupId>
   <artifactId>nekohtml</artifactId>
</dependency>

<dependency>
   <groupId>org.thymeleaf</groupId>
   <artifactId>thymeleaf</artifactId>
   <version>3.0.6.RELEASE</version>
</dependency>

<dependency>
   <groupId>org.thymeleaf</groupId>
   <artifactId>thymeleaf-spring4</artifactId>
   <version>3.0.6.RELEASE</version>
</dependency>

<dependency>
   <groupId>commons-io</groupId>
   <artifactId>commons-io</artifactId>
   <version>2.4</version>
</dependency>

<dependency>
   <groupId>commons-fileupload</groupId>
   <artifactId>commons-fileupload</artifactId>
   <version>1.3.1</version>
</dependency>

<dependency>
   <groupId>nz.net.ultraq.thymeleaf</groupId>
   <artifactId>thymeleaf-layout-dialect</artifactId>
   <version>2.1.2</version>
</dependency>

<dependency>
   <groupId>javax.servlet</groupId>
   <artifactId>javax.servlet-api</artifactId>
   <version>3.1.0</version>
</dependency>

2.在application.yml添加相关配置:

spring:
  thymeleaf:
    cache: false
    mode: LEGACYHTML5
  output:
    ansi:
      enabled: always
  mail:
    default-encoding: UTF-8
server:
  port: 8088

3.在emailconfig.properties需要添加邮件服务器的host,username,password:

mail.server.host=smtp.163.com
mail.server.port=25
mail.server.protocol=smtp
mail.server.username=
mail.server.password=
mail.server.from=

4.启动项目后访问http://localhost:8088

这个示例，是在thymeleaf官网示例的基础上修改的
