java spring 邮件发送

　　开发中经常会遇到发送邮件进行用户验证，或者其它推送信息的情况，本文基于spring，完成邮件的发送，主要支持普通文本邮件的发送，html文本邮件的发送，带附件的邮件发送，没有实现群发、多个附件发送等需求。如果需要可以参照如下源代码进行修改完成。

1. POM文件配置

    <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>
                <version>4.1.6.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context-support</artifactId>
                <version>4.1.6.RELEASE</version>
            </dependency>
            <dependency>
                <groupId>javax.mail</groupId>
                <artifactId>mail</artifactId>
                <version>1.4.7</version>
            </dependency>
        </dependencies>

   POM dependencies

2. spring 配置

    <!-- Production implementation of the JavaMailSender interface, supporting
            both JavaMail MimeMessages and Spring SimpleMailMessages -->
        <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
            <property name="host" value="smtp.gmail.com" />
            <property name="port" value="587" />
            <property name="username" value="<!-- Provide your Gmail ID -->" />
            <property name="password" value="<!-- Provide your Gmail Password -->" />
   
            <!-- The name of the property, following JavaBean naming conventions -->
            <property name="javaMailProperties">
                <props>
                    <prop key="mail.transport.protocol">smtp</prop>
                    <prop key="mail.smtp.auth">true</prop>
                    <prop key="mail.smtp.starttls.enable">true</prop>
                    <prop key="mail.debug">true</prop>
                </props>
            </property>
        </bean>

            String filePath = "d://1.sql";
            String fileName = "haha.sql";
            try {
