SpringMVC 在业务控制方法中收集数组及List<JavaBean>参数

收集数组数据

@Controller
@RequestMapping(value="/user")
public class UserAction {
@RequestMapping(value="/delete")
public String deleteMethod(int[] ids,Model model) throws Exception{
System.out.println("UserAction::deleteMethod()");
System.out.println("需要删除的id为：");
for(int id : ids){
System.out.print(id+" ");
}
model.addAttribute("message","批量删除成功");
return "/success.jsp";
}
}

收集List参数

@Controller
@RequestMapping(value="/user")
public class UserAction {
@RequestMapping(value="/addAll")
public String addAll(Bean bean,Model model) throws Exception{
for(User user : bean.getUserList()){
System.out.println(user.getName()+":"+user.getGender());
}
model.addAttribute("message","批量增加用户成功");
return "/success.jsp";
}
}

public class Bean {
private List<User> userList = new ArrayList<User>();
public Bean(){}
public List<User> getUserList() {
return userList;
}
public void setUserList(List<User> userList) {
this.userList = userList;
}
}

<form action="${pageContext.request.contextPath}/user/addAll.action" method="POST">
