使用javaMail和velocity来发送模板邮件

时间：2021-10-11 20:50:23

之前在ssh项目中有用过javaMail和velocity来发送邮件，实现的效果如下所示。

使用javaMail和velocity来发送模板邮件

这类邮件主要用于公司的推广宣传，比如商城的促销等场景。

今天打算将邮件模块也集成到ssm项目，也算是对之前做的东西的一种巩固。

简单邮件模块

首先来集成简单的邮件模块。

1.第一步，加jar包，在maven的pom.xml加入如下代码。

<!-- 邮件 -->

        <dependency>

            <groupId>javax.mail</groupId>

            <artifactId>javax.mail-api</artifactId>

            <version>1.6.0</version>

        </dependency>

        <dependency>

        <groupId>com.sun.mail</groupId>

        <artifactId>smtp</artifactId>

        <version>1.6.0</version>

        <type>jar</type>

        <scope>compile</scope>

    </dependency>

      <dependency>

        <groupId>com.sun.mail</groupId>

        <artifactId>mailapi</artifactId>

        <version>1.6.0</version>

        <type>jar</type>

        <scope>compile</scope>

    </dependency>

2.编写mail.properties配置文件

#邮箱参数配置

mail.host:smtp.qq.com

mail.port:25

mail.username:xxxxx

mail.password:xxxxxx

3.在spring主配置文件中引入此配置文件

<!-- 读取properties文件 参数配置,所有的参数配置均可放在此处 -->

    <bean id="propertyConfigurer"

        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">

        <property name="locations">

            <list>

                <value>classpath:jdbc.properties</value>

                <value>classpath:mail.properties</value>

            </list>

        </property>

    </bean>

4.新建spring-mail.xml文件，用于配置邮件相关的内容。

<?xml version="1.0" encoding="UTF-8" standalone="no"?>

<beans xmlns="http://www.springframework.org/schema/beans"

    xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx"

    xmlns:util="http://www.springframework.org/schema/util" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd  http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd  http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd  http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util.xsd  ">

    <bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">

        <property name="host" value="${mail.host}" />

        <property name="port" value="${mail.port}" />

        <property name="username" value="${mail.username}" />

        <property name="password" value="${mail.password}" />

        <property name="javaMailProperties">

            <props>

                <prop key="mail.smtp.auth">true</prop>

            </props>

        </property>

    </bean>

</beans>

5.在主配置文件中引入spring-mail.xml配置文件。

<import resource="spring-mail.xml" />

6.在一个controller类中编码调用邮件，注意需要注入mailSender这个bean.

    @Resource(name = "mailSender")

    private JavaMailSender mailSender;
@ResponseBody

    @RequestMapping(value = "simpleMailDemo", produces = "text/html; charset=utf-8")

    public String simpleMailDemo() {

        SimpleMailMessage mail = new SimpleMailMessage();

        JavaMailSenderImpl mailSenderImpl = (JavaMailSenderImpl) mailSender;

        // 发送方

        mail.setFrom(mailSenderImpl.getUsername());

        // 接收方

        mail.setTo("2717814812@qq.com");

        // 标题

        mail.setSubject("spring mvc简单邮件发送");

        // 设置邮件正文

        mail.setText("spring mvc简单邮件发送，收到此邮件表明邮件模块配置成功");

        mailSender.send(mail);

        return "成功";

    }

7.在浏览器输入http://192.168.1.185:8080/warrior/simpleMailDemo，结果如图。

使用javaMail和velocity来发送模板邮件

看看邮箱，确实收到了邮件。

使用javaMail和velocity来发送模板邮件

 采用velocity模板编写富文本邮件

1.第一步，引入velocity所需要用到的jar文件。

<dependency>

            <groupId>org.apache.velocity</groupId>

            <artifactId>velocity</artifactId>

            <version>1.7</version>

        </dependency>

2.在spring-mail.xml中加入关于velocity的配置。

    <bean id="velocityEngine"

        class="org.springframework.ui.velocity.VelocityEngineFactoryBean">

        <property name="resourceLoaderPath" value="/WEB-INF/templates/" /><!--

            模板存放的路径 -->

        <property name="configLocation" value="classpath:velocity.properties" />

    </bean>

    <!--配置试图解析器 -->

    <bean id="viewResolver"

        class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">

        <property name="cache" value="false" />

        <property name="prefix" value="" />

        <property name="suffix" value=".vm" />

        <property name="contentType" value="text/html;charset=utf-8" />

        <property name="toolboxConfigLocation" value="/WEB-INF/toolbox.xml" />

        <property name="exposeSpringMacroHelpers" value="true" />

        <property name="exposeRequestAttributes" value="true" />

        <property name="exposeSessionAttributes" value="true" />

        <property name="allowSessionOverride" value="true" />

        <property name="allowRequestOverride" value="true" />

    </bean>

注意上述配置我们将velocity的模板存在了web-inf下的templates文件夹下，并且启用了toolbox.xml配置，toolbox.xml主要是一些工具，你可以把你在编写velocity模板的时候可能会用到的工具填写到toolbox.xml中。

3.注意上述配置文件引入了velocity.properties文件，在resources下新建velocity.properties文件。

input.encoding=UTF-8

output.encoding=UTF-8

4.在web-inf下新建templates文件夹，新建toolbox.xml，此处我随便写了两个工具到toolbox.xml里面。

<?xml version="1.0" encoding="UTF-8" ?>

<toolbox>

    <tool>

        <key>UrlUtil</key>

        <class>com.nali.common.util.UrlUtil</class>

        <scope>application</scope>

    </tool>

    <tool>

        <key>VersionUtil</key>

        <class>com.ximalaya.shop.api.domain.util.VersionUtil</class>

        <scope>application</scope>

    </tool>

</toolbox>

4.编写velocity模板，在templates文件夹下面新建一个名为test.vm的模板。

模板的编写与html文件类似，还可以试用循环。仔细看上述内容就可以发现。

5.最后，我们编写一个controller的方法来实现发送富文本邮件。

package com.xdx.controller;

import java.io.UnsupportedEncodingException;

import java.util.HashMap;

import java.util.List;

import java.util.Map;

import javax.annotation.Resource;

import javax.mail.MessagingException;

import javax.mail.internet.MimeMessage;

import org.apache.velocity.app.VelocityEngine;

import org.springframework.mail.SimpleMailMessage;

import org.springframework.mail.javamail.JavaMailSender;

import org.springframework.mail.javamail.JavaMailSenderImpl;

import org.springframework.mail.javamail.MimeMessageHelper;

import org.springframework.stereotype.Controller;

import org.springframework.ui.velocity.VelocityEngineUtils;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import com.xdx.entity.TProduct;

import com.xdx.service.ProductService;

@Controller

public class DemoController {

    @Resource(name = "mailSender")

    private JavaMailSender mailSender;

    @Resource(name = "velocityEngine")

    private VelocityEngine velocityEngine;

    @Resource(name = "productService")

    private ProductService productService;

    @ResponseBody

    @RequestMapping(value = "simpleMailDemo", produces = "text/html; charset=utf-8")

    public String simpleMailDemo() {

        SimpleMailMessage mail = new SimpleMailMessage();

        JavaMailSenderImpl mailSenderImpl = (JavaMailSenderImpl) mailSender;

        // 发送方

        mail.setFrom(mailSenderImpl.getUsername());

        // 接收方

        mail.setTo("2717814812@qq.com");

        // 标题

        mail.setSubject("spring mvc简单邮件发送");

        // 设置邮件正文

        mail.setText("spring mvc简单邮件发送，收到此邮件表明邮件模块配置成功");

        mailSender.send(mail);

        return "成功";

    }

    @ResponseBody

    @RequestMapping(value = "velocityMailDemo", produces = "text/html; charset=utf-8")

    public String velocityMailDemo() throws UnsupportedEncodingException,

            MessagingException {

        JavaMailSenderImpl mailSenderImpl = (JavaMailSenderImpl) mailSender;

        MimeMessage mimeMessage = mailSenderImpl.createMimeMessage();

        MimeMessageHelper helper = new MimeMessageHelper(mimeMessage, "utf-8");

        helper.setFrom(mailSenderImpl.getUsername(), "逸品周刊");

        helper.setTo("2717814812@qq.com");

        // 主题

        helper.setSubject("velocity模板邮件发送");

        String template = "test.vm";

        List<TProduct> productList = productService.getHotProductList();//获取商品列表

        Map<String, Object> model = new HashMap<String, Object>();

        model.put("productList", productList);

        String result = null;

        try {

            result = VelocityEngineUtils.mergeTemplateIntoString(

                    velocityEngine, template, "UTF-8", model);

        } catch (Exception e) {

        }

        helper.setText(result, true);

        try {

            mailSenderImpl.send(mimeMessage);

        } catch (Exception e) {

            e.printStackTrace();

        }

        return "成功";

    }

}

7.最后看一下，整个项目的目录。
