    public static boolean sendHtml(String email, String title, String html) {

    }
}

 

在pom.xml文件中加上郵件的jar包

<dependency>
   <groupId>org.apache.commons</groupId>
   <artifactId>commons-email</artifactId>
   <version>1.5</version>
</dependency>

 

 

獲郵箱的許可碼方法

一、打開qq郵箱，點擊設置

 

二、選擇帳號

三、點擊開啓pop3/smtp服務

四、按步驟發送驗證（驗證方法有多種，可是個人只有一種）

五、保存該受權碼，設置到工具類便可
