使用Spring发送邮件

1. [代码]properties 文件     

? 1 2 3 4 5 6 7 8 9 10 11 12 13 #配置服务器邮件账号信息 #服务器 mail.smtp.host=smtp.xxx.com #是否需要验证密码 mail.smtp.auth=true #超时时间 mail.smtp.timeout=25000 #发件人信箱 mail.smtp.from=xxx@163.com #用户名 mail.smtp.username=xxx@163.com #密码 mail.smtp.password=123456

2. [代码]配置 applicationContext.xml     

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16      <!-- in-memory database and a datasource -->      < bean id = "propertyConfigurer"            class = "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"            p:location = "classpath:jdbc.properties" /> <!-- 配置邮件 senderbean --> < bean id = "mailSender" class = "org.springframework.mail.javamail.JavaMailSenderImpl" >      < property name = "host" value = "${mail.smtp.host}" ></ property >      < property name = "javaMailProperties" >          < props >              < prop key = "mail.smtp.auth" >${mail.smtp.auth}</ prop >              < prop key = "mail.smtp.timeout" >${mail.smtp.timeout}</ prop >                </ props >      </ property >      < property name = "username" value = "${mail.smtp.username}" ></ property >      < property name = "password" value = "${mail.smtp.password}" ></ property > </ bean >

3. [代码]编写 ACTION 代码，实现邮件发送功能，这里还附加了一个附件     

? 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100 101 102 103 104 105 106 107 108 109 110 111 112 113 114 115 116 117 118 119 120 121 122 123 124 125 126 127 128 129 130 131 132 133 134 135 136 137 138 139 140 141 142 143 144 145 146 147 148 149 150 151 152 153 154 155 156 157 158 159 160 161 162 163 164 165 166 167 168 169 170 171 172 173 174 175 176 177 /**   ********************************************************************************************   * @ClassName: ForcastAction   * @Description: TODO   * @author ZhouQian   * @date 2014-6-11-上午11:00:34   ********************************************************************************************   */ public class ForcastAction extends ActionSupport implements ServletRequestAware, ServletResponseAware, SessionAware {      private static final long serialVersionUID = 1L;
