SQL绑定变量的那些事

1.String bankAccountName = null == cb.getBankAccountName()?"":cb.getBankAccountName().trim();

测试找个spring定时器，修改定时器时间，在定时器调用的函数里增加如下的入口测试：

if(true){

          WebApplicationContext spring = ContextLoader.getCurrentWebApplicationContext();

           //WebApplicationContext spring =WebApplicationContextUtils..getRequiredWebApplicationContext(ServletActionContext.getServletContext());

           CcsCustomerReceiverDaoccsCustomerReceiverDao=(CcsCustomerReceiverDao)spring.getBean("ccsCustomerReceiverDao");

           Contact contact = newContact();

           contact.setName("汪先生");

           contact.setCustid("7559957925");

           contact.setId("7559957925002");

           contact.setOp("U");

          ccsCustomerReceiverDao.saveCcsCustContact(contact);

           return;

       }

 

进行修改测试。
