调用方法

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import sdcounty.dcss.cat.ApplicationMailer;
@RequestMapping(value = "/Error", method = { RequestMethod.POST, RequestMethod.GET })
    public ModelAndView handleError(HttpServletRequest request) {`
        
        //Create the application context
        ApplicationContext context = new ClassPathXmlApplicationContext("application-context.xml");
         
        //Get the mailer instance
        ApplicationMailer mailer = (ApplicationMailer) context.getBean("applicationMailer");

        //Error Message
        String errorMessage = (String) request.getAttribute("javax.servlet.error.exception") + String.format("%n") +
                              (String) request.getAttribute("javax.servlet.error.exception_type") + String.format("%n") +
                              (String) request.getAttribute("javax.servlet.error.request_uri") + String.format("%n") +
                              (String) request.getAttribute("javax.servlet.error.servlet_name") + String.format("%n") +
                              //(Integer) request.getAttribute("javax.servlet.error.status_code") + String.format("%n") +
                              (String) request.getAttribute("javax.servlet.error.message") + String.format("%n");
