最近做了一个发送邮件的功能，做一个邮件的模板，只要将以下字段保存到数据库中即可。

private Long xh;
    	private String ETitle;//邮件主题
    	private String EContent;//邮件内容（freeMarker页面）
    	private String EMail;//邮件发送人
    	private Date ETime;//邮件发送时间
    	private String bcc;//密送人
    	private String cc;//抄送人
    	private String replyto;
    	private String appendix;
    	private String type;

邮件模板实现如下：

// 手动生成数据后发送邮件
    	public void sendEmail(Map paramsMap) throws Exception {
    		
    		// 获取合同ID
    		String pactId = (String) paramsMap.get("pactId"); 
    		
    		// 获取邮件发送人信息
    		Map innerSignInfo = pactBaseinfoInnerSignDao.queryPactBaseinfoInnerSignInfoList(paramsMap);
    		// 获取邮件发送内容的数据
    		List signFileList = pactBaseinfoInnerSignDao.queryPactBaseinfoSignFile(pactId);
    		
    		// 获取邮件发送的数据
    		if(null != innerSignInfo)
    		{  
    			// 内部交易合同信息放入Map  
    			paramsMap.put("innerSignInfo", innerSignInfo);
    			paramsMap.put("signFileList", signFileList);
    			
    			// 邮件发送人、抄送人 
    			String bu = "";
    			String email = "";
    			paramsMap.put("bu", innerSignInfo.get("BU").toString());
    			List sendInfoList = new ArrayList();
    			sendInfoList = pactBaseinfoInnerSignDao.getSendInfoList(paramsMap);
    			if(sendInfoList.size() > 0  && "" != sendInfoList.get(0) && null != sendInfoList.get(0) && ""!=((Map)sendInfoList.get(0)).get("CHECK_VALUE") && null !=((Map)sendInfoList.get(0)).get("CHECK_VALUE"))
    			{
    				email = (String) ((Map)sendInfoList.get(0)).get("CHECK_VALUE");
    //					String names = "yuzt"; 
    //					paramsMap.put("userName", names);
    				TbPactAccEmail tbPactAccEmail = new TbPactAccEmail(); 
    				tbPactAccEmail.setEMail(email);
    				tbPactAccEmail.setETitle(this.titel1);
    				
    				paramsMap.put("mailType", mailType1);
    				
    				String mailContent = this.getMailContentByType(paramsMap); 
    				String welcomeInfo = this.getWelcomeInfo(paramsMap); 
    				mailContent = mailContent.replaceFirst("#welcomeInfo#", welcomeInfo);
    //			    mailContent = mailContent.replaceFirst("#userName#", names);
    
    				tbPactAccEmail.setEContent(mailContent); 
    				pactBaseinfoInnerSignDao.doSaveMail(tbPactAccEmail); 
    //				pactInforEmailDao.saveEmail(email, "", titel1, mailContent);
    			}  
    			 
    		}  
    	}
    	
    	// 将邮件内容塞入模板
    	private String getMailContentByType(Map paramsMap) throws Exception {
    		String mailType = paramsMap.get("mailType").toString();
    
    		String pactContent = getPactInnerContent(paramsMap); 
    
    		String path = BuildFileFM.path() + "/model";// 邮件内容模板路径
    		BuildFileFM fileFM = new BuildFileFM(path, "UTF-8");
    
    		Map infoMap = new HashMap();
    		infoMap.put("pactContent", pactContent); 
    		infoMap.put("userName", paramsMap.get("userName"));
    		// infoMap.put("welcomeInfo", this.getWelcomeInfo(paramsMap));
    		return fileFM.buildFileContent("pactBaseInnerSignEmail.ftl", infoMap);
    	}
    	
    	// 邮件正文内容
    	private String getPactInnerContent(Map paramsMap) throws Exception 
    	{ 
    		String path = BuildFileFM.path() + "/model";// 邮件内容模板路径
    		BuildFileFM fileFM = new BuildFileFM(path, "UTF-8"); 
     
    		return fileFM.buildFileContent("pactBaseInnerSignInfo.ftl", paramsMap);
    
    	}
    	
    	// 邮件开头的welcome信息
    	private String getWelcomeInfo(Map paramsMap) throws Exception {
    		Map innerSignInfo =   (Map) paramsMap.get("innerSignInfo"); 
    		String mailType = paramsMap.get("mailType").toString(); 
    		String pactId = (String) innerSignInfo.get("PACT_ID");  
    		String pactCode = (String) innerSignInfo.get("PACT_CODE");  
    		String pactName = (String) innerSignInfo.get("PACT_NAME");  
    		String EMPNUM = (String) innerSignInfo.get("EMPNUM");  
    		String LAST_NAME = (String) innerSignInfo.get("LAST_NAME");   
    		String currentDateStr = DateTool.getCurrrentDate1();
    		String welcomeInfo = "";
         
    		if (mailType1.equals(mailType)) {
    			//提交成功
    			welcomeInfo = LAST_NAME +"(工号:"+EMPNUM+")"+ "于"+currentDateStr+"将:"+pactName+"(合同编码:"+pactCode+")标记为大签。合同的详细信息如下："; 
    		}  
    
    		return welcomeInfo;
    	}
