網絡SMTP：JavaMail+騰訊SMTP服務

說明

版本一不能整合到Spring，版本二已經整合到Spring

版本1

package com.ddouble.util.email;
/**
 * 	
 * 	SMTP(simple mail transfer protocol)
 * 	郵件發送工具
 * 	@author Ddouble
 *     copyright all reserved  2016 by author in  AHU(CN)
 *     @desc
 *     一、【問題】不能整合到spring框架，如今已經遷移使用spring自帶的JavaMailSender
 *     二、【問題】由於從jaee5開始jdk集成JavaMail和JavaAction，本身引用新的這兩個包
 *                            會有版本衝突（尤爲在集成到框架並部署到服務器上）
 *     三、【問題】SSL認證問題。jdk8會影響郵箱服務的認證，須要更換現有jdk的jce環境
 *     					詳情參考：http://www.cnblogs.com/LUA123/p/6039954.html
 *     四、【問題】騰訊SMTP開啓，自行百度。

}

版本2 SpringSMTP服務

1 引入pom.xml依賴

<!-- mail -->
    <dependency>
        <groupId>javax.mail</groupId>
        <artifactId>mail</artifactId>
        <version>1.4.7</version>
    </dependency>

2 applicationContext.xml中配置mail的bean，smtp服務的設置

<bean id="mailMessage"  class ="org.springframework.mail.SimpleMailMessage">
        <property name="from" value="9XXXXXX6@qq.com"/>
    </bean>
    
    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
        <property name="host" value="smtp.qq.com"/>
        <property name="port" value="587"/>
        <property name="username" value="9XXXXXXXX6"/>
        <property name="password" value="hhdiphpvfivvbfih"/>
        <property name="defaultEncoding" value="UTF-8"/>
        <property name="javaMailProperties">
            <props>
                <prop key="mail.smtp.auth">true</prop>
                <prop key="mail.smtp.timeout">25000</prop>
                <prop key="mail.debug">true</prop>
                <prop key="mail.smtp.starttls.enable">true</prop>
     			<prop key="mail.smtp.ssl.trust">smtp.qq.com</prop>
            </props>
        </property>	
    </bean>
