通过common-emai类库发送普通邮件和带有附件的邮件的完整示例，,1.此示例是通过mave

1.此示例是通过maven构建,pom.xml文件如下：

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"        xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">        <modelVersion>4.0.0</modelVersion>        <groupId>com.ilucky.util.email</groupId>        <artifactId>email-util</artifactId>        <version>1.0-SNAPSHOT</version>        <packaging>war</packaging>        <name>email-util</name>        <url>http://maven.apache.org</url>        <properties>          <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>        </properties>        <dependencies>          <dependency>              <groupId>org.apache.commons</groupId>              <artifactId>commons-email</artifactId>              <version>1.3.3</version>          </dependency>        </dependencies>      </project>  

2.工具类如下：```javaimport java.net.URL;

}

3.测试类如下：```javaNone

注意：java eu.setDefaultAuthenticatorUsername("sidongxue"); eu.setDefaultAuthenticatorPassword("123456");此处用自己的邮箱用户名和密码.
