JSP页面上有个按钮被按 按钮ID为customInfoChangeHistory 写一个如下JS （按钮单击事件） //客户信息更改历史 $(#customInfoChangeHistory).click(function(){ var urlStr = new $.Template(${contextPath }telesales:constant fieldName=CUSTOMER_INFO_HISTORY_INDEX shortClassName=Url/); var urlParam = {customerId: customer_id, taskId: taskId}; var CustomInfoChangeHistory = urlStr.expand(urlParam); window.open(CustomInfoChangeHistory); }); 其中$.Template(${contextPath }telesales:constant fieldName=CUSTOMER_INFO_HISTORY_INDEX shortClassName=Url/); 调用名字为CUSTOMER_INFO_HISTORY_INDEX 的 Controller是一个JAVA类。 var urlParam = {customerId: customer_id, taskId: taskId}; 是传入到Controller的值. 2．Controller如下 /** * pTitle: queryCustomerHistory/p * pDescription:查询 客户历史记录/p * @return 返回视图 * @author Leon.Qiu 2010-11-8 下午05:02:13 */ @RequestMapping(value = Url.CUSTOMER_INFO_HISTORY_INDEX, method = RequestMethod.GET) public String queryCustomerHistory(@PathVariable final long customerId, @PathVariable final long taskId, final ModelMap map) { map.addAttribute(customerId, customerId); map.addAttribute(taskId, taskId); return Views.MAIN_CUSTOMER_HISTORY_VIEW; } Url.CUSTOMER_INFO_HISTORY_INDEX与上面名字同 3．该Controller会调用相应的SERVICES SERVICES如下： /** * pTitle: getGroupAndCampaignStatus/p * pDescription: 根据任务ID获取组别和活动状态/p * @param taskId 任务ID * @return 返回组别和活动状态Map * @author Leon.Qiu 2010-11-2 下午04:22:12 */ @Transactional(timeout = 3, isolation = Isolation.READ_COMMITTED, propagation = Propagation.REQUIRED, readOnly = true) public MapString, BigDecimal getGroupAndCampaignStatus(long taskId) { return customerInfoDAO.selectByGroupAndCampaignStatus(taskId); } Services中如果 需要调用数据库 会调用DAO 4．DAO使用如下 /** * pTitle: selectByGroupAndCampaignStatus/p * pDescription: 根据TaskId判断返回Task是否可执行状态/p * @param taskId 任务的ID * @return 返回组别和活动的任务状态 * @author Leon.Qiu 2010-11-1 下午08:47:04 */ @SuppressWarnings(unchecked) public MapString, BigDecimal selectByGroupAndCampaignStatus(long taskId) { return (
