Spring本身有mail支持，所以用spring发邮件其实是个挺简单的事，看看其jar包
<dependency>
<groupId>org.springframework.integration</groupId>
<artifactId>spring-integration-mail</artifactId>
<version>4.2.6.RELEASE</version>
</dependency>
1:pom.xml
需要下载strut2 spring的核心包 mail.jar 以及activation.jar
<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/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.zhao</groupId> <artifactId>Struts2_Spring</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>Struts2_Spring Maven Webapp</name> <url>http://maven.apache.org</url> <dependencies> <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4.7</version> </dependency> <dependency> <groupId>javax.activation</groupId> <artifactId>activation</artifactId> <version>1.1.1</version> </dependency> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-json-plugin</artifactId> <version>2.3.24</version> </dependency> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.0.1</version> <!-- 只在编译时和测试时运行 --> <scope>provided</scope> </dependency> <!-- Struts2 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-core</artifactId> <version>2.3.24</version> </dependency> <!-- convention-plugin插件，使用了这个插件之后，就可以采用注解的方式配置Action --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-convention-plugin</artifactId> <version>2.3.24</version> </dependency> <!-- struts2和spring整合 --> <dependency> <groupId>org.apache.struts</groupId> <artifactId>struts2-spring-plugin</artifactId> <version>2.3.24</version> </dependency> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.integration</groupId> <artifactId>spring-integration-mail</artifactId> <version>4.2.6.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-expression</artifactId> <version>4.0.4.RELEASE</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-orm</artifactId> <version>4.0.4.RELEASE</version> </dependency> </dependencies> <build> <finalName>Struts2_Spring</finalName> </build> </project>
2：spring_bean.xml
第一个bean是spring的支持，第二个bean是我自定义的Struts2 Action，然后依赖注入
<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl"> <property name="host" value="smtp.163.com" /> <property name="username" value="username"/> <property name="password" value="password" /> </bean> <bean id="sendMail" class="com.zhao.action.SendMailAction" scope="singleton"> <property name="mailSender" ref="mailSender"></property> </bean>
3：struts.xml
页面流程也很简单，成功了就进入成功界面
<struts> <package name="default" extends="struts-default"> <action name="send" class="com.zhao.action.SendMailAction"> <result>success.jsp</result> </action> <action name="sendHtml" class="com.zhao.action.SendMailAction" method="sendHtml"> <result>success.jsp</result> </action> </package> </struts>
4：SendMailAction
我们通过依赖注入，得到了JavaMailSenderImpl的对象，然后通过这个对象进行邮件的发送。
package com.zhao.action; import javax.mail.internet.MimeMessage; import org.springframework.mail.SimpleMailMessage; import org.springframework.mail.javamail.JavaMailSenderImpl; import org.springframework.mail.javamail.MimeMessageHelper; import com.opensymphony.xwork2.ActionSupport; /** * * @author: zhao * @time: 2016年5月14日 * * @description:Struts2 + Spring 发送邮件 */ public class SendMailAction extends ActionSupport{ private static final long serialVersionUID = 1L; private JavaMailSenderImpl mailSender;
//简单邮件发送 @Override public String execute() throws Exception { SimpleMailMessage message=new SimpleMailMessage(); message.setTo("to@163.com"); message.setFrom("from@163.com"); message.setSubject("练习"); message.setText("这只是一个简单的练习"); mailSender.send(message); return SUCCESS; }
//html邮件发送 public String sendHtml() throws Exception{ MimeMessage message=mailSender.createMimeMessage(); MimeMessageHelper messageHelper=new MimeMessageHelper(message); messageHelper.setTo("to@163.com"); messageHelper.setFrom("from@163.com"); messageHelper.setSubject("Html练习"); messageHelper.setText("<html><head></head><body><h1>SUCCESS</h1></body></html>",true); mailSender.send(message); return SUCCESS; } public JavaMailSenderImpl getMailSender() { return mailSender; } public void setMailSender(JavaMailSenderImpl mailSender) { this.mailSender = mailSender; } }
5：错误解决
正常来说上面的步骤就足够了，但是是我遇到了两个错误
550 User has no permission
535 Error: authentication failed
550是说邮箱没有启用ssl/tls认证，所以我们直接发邮件肯定是失败的。
进入网易邮箱，开始相应服务
在这个过程会让你自己输入一个授权码，跟密码差不多，只不过你采用ssl方式登录时，需要输入授权码 ，而不是你的账号密码。这个授权码就是负责你在第三方登录的。
接下来我又遇到了535错误，这个错误的意思是验证不通过，密码不对。需要修改sprng_bean.xml中的账号密码，改成授权码，然后就好了。
好了，问题完美解决。
