代码
public void emailCheck() throws IOException{
HttpServletResponse response=ServletActionContext.getResponse();
response.setContentType("text/json;charset=GB18030");
response.setHeader("Cache-Control", "no-cache");
PrintWriter out;
out = response.getWriter();
JSONObject json=new JSONObject();
EmailImpl ei;
this.emp=new Emp();
this.emp.setId(1);
this.emp.setName("DerrickJJ");
this.emp.setPassword("123456");
this.nowpage=0;
if(this.ka==0){
ApplicationContext ac = new ClassPathXmlApplicationContext("beans.xml");
ei=(EmailImpl)ac.getBean("emaildao");
this.list = ei.checkUnreadEmail(emp, nowpage);
System.out.println("ka=0");
this.list.get(0).setContent("未读");
}else if(this.ka==1){
ei=(EmailImpl)AppBeans.ac.getBean("emaildao");
System.out.println("ka=1");
this.list = ei.checkRecEmail(emp, nowpage);
this.list.get(0).setContent("收");
}else{
ei=(EmailImpl)AppBeans.ac.getBean("emaildao");
System.out.println("ka=2");
this.list = ei.checkSendEmail(emp, nowpage);
this.list.get(0).setContent("发");
}
EmailsendToOther eto = new EmailsendToOther();
ArrayList<EmailsendOther> listother = eto.emailsendToOther(list);
for(EmailsendOther eo:listother){
System.out.println(eo.getSendTime());
}
json.put("list",listother);
out.println(json);
out.flush();
out.close();
}
