Answer 1

没有错误提示信息，这个是Action中添加关注的方法：
public String addFollow(){
HttpServletRequest request = ServletActionContext.getRequest();
Integer trigono = (Integer)request.getAttribute("trigono");
System.out.println(trigono);
if(trigono!=null){
User u = (User)ActionContext.getContext().getSession().get("user");
User u1 = userservice.isThisTrigonoUsed(trigono);
System.out.println("user:"+u.getTrigono());
System.out.println("user:"+u.getEmail());
System.out.println("user1:"+u1.getTrigono());
System.out.println("user1:"+u1.getEmail());
System.out.println("followsize::"+user.getFollowing().size());
u.getFollowing().add(u1);
u1.getFollowed().add(u);
System.out.println("getFollowing:");
userservice.update(u);
}else{
System.out.print("hhyhh");
return "addfollowfail";
}


return "addfollowsuccess";
}
