利用springframework+javax.mail发邮件（普通邮件、带附件邮件、HTML格式邮件）
Spring提供了发送电子邮件的支持，可以发送普通邮件、带附件邮件、HTML格式邮件，甚至还可以使用Velocity模板定制化邮件内容。
一、引入相关的库
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | <!-- spring核心库 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.2.5.RELEASE</version> </dependency> <!--发送Email--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context-support</artifactId> <version>4.2.5.RELEASE</version> </dependency> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.7</version> </dependency> |
