這里使用的是JavaMail技術(shù)，前臺(tái)使用了fckeditor做郵件美化，由于只是示例，后臺(tái)發(fā)送時(shí)只是將郵件保存在本地，但是可以查看，如果需要實(shí)際發(fā)送，請(qǐng)參考我的其他博客文章，我寫了很多關(guān)于郵件發(fā)送的示例！

JSP頁(yè)面頁(yè)面除了引用fckeditor外，要注意我們是需要發(fā)送附件的：

為了防止亂碼，會(huì)經(jīng)過一個(gè)過濾器：

package org.filter; 
import java.io.IOException; 
import javax.servlet.Filter; 
import javax.servlet.FilterChain; 
import javax.servlet.FilterConfig; 
import javax.servlet.ServletException; 
import javax.servlet.ServletRequest; 
import javax.servlet.ServletResponse; 
/** 
 * 過濾器防止亂碼 
 * @說明 
 * @author cuisuqiang 
 * @version 1.0 
 * @since 
 */ 
public class EncodingFilter implements Filter { 
  public void destroy() { 
  } 
  public void doFilter(ServletRequest request, ServletResponse response, 
      FilterChain chain) throws IOException, ServletException { 
    request.setCharacterEncoding("UTF-8"); 
    response.setCharacterEncoding("UTF-8"); 
    chain.doFilter(request, response); 
  } 
  public void init(FilterConfig arg0) throws ServletException { 
  } 
}

然后到Servlet處理附件和信息，這里就不做異常處理了，出錯(cuò)直接報(bào)錯(cuò)：

package org.servlet; 
import java.io.*; 
import java.util.*; 
import javax.servlet.ServletException;

    } catch (Exception e) { 
      e.printStackTrace(); 
    } 
    response.sendRedirect(request.getContextPath() + "/sendmail.jsp"); 
  } 
}

這里也沒有驗(yàn)證，接收到信息后組裝一個(gè)郵件實(shí)體對(duì)象，傳遞到發(fā)送接口中發(fā)送：
實(shí)體，我就不寫ｇｅｔ和ｓｅｔ方法了：

package org.entity; 
/** 
 * 一封郵件的對(duì)象 
 * @說明 
 * @author cuisuqiang 
 * @version 1.0

 */ 
public class MailModel { 
  /** 
   * 主鍵 
   */ 
  private int id; 
 
  /** 
   * 郵件標(biāo)題 
   */ 
  private String title; 
 
  /** 
   * 發(fā)送給誰(shuí) 
   */ 
  private String to; 
 
  /** 
   * 背景圖片地址 
   */ 
  private String bgPath; 
 
  /** 
   * 抄送給誰(shuí) 
   */ 
  private String copy; 
 
  /** 
   * 郵件內(nèi)容 
   */ 
  private String context; 
 
  /** 
   * 附件地址 
   */ 
  private String filePath; 
  /** 
   * 背景音樂地址 
   */ 
  private String musicPath; 
}
