在我的应用程序中，我尝试连接到不同的应用程序并保存数据。在那部分中，我成功地保存了该数据。但问题是当我保存电子邮件时，它必须触发预定义的电子邮件建议。但它没有发生。这是我在这个问题中解释的连接代码，而我在其他应用程序的 servlet 中的代码是。

ApplicationContext context = WebApplicationContextUtils.getRequiredWebApplicationContext(getServletContext());

String uname = request.getParameter("userName");
String pwd = request.getParameter("pwd");
String email = request.getParameter("email");

userDao.insertUser(user);
passDao.insertPassword(password);

User u1 =userDao.getUser(domain, uname);

Email command = new Email();

command.setCreationDate(new Date());
command.setAddress(email);
command.setUser(u1);
command.setLocale(new Locale("en","US"));

log.debug("Upto user adding data");

JosService josService = (JosService)context.getBean("josService");

try {
    log.debug("before adding email data");
    josService.insertEmail(u1,command);
    log.debug("After adding email data");
} catch (Exception e) {
    log.error("Setting and sending email address is failed");
    e.printStackTrace();
}

log.debug("Data saved succesfully");
response.setStatus(200);

在我的 applicationcontext.xml 中有这样定义的建议
