springmvc在業務控制方法中收集List參數,實現批量處理

用大模型包括其他小模型，實現批量處理

UserAction.java

@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","批量增加用戶成功");
		return "/success.jsp";
	}
}

 Bean.java

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;
	}
}

registerAll.jsp

<form action="${pageContext.request.contextPath}/user/addAll.action" method="POST"> 
		 
		姓名：<input type="text" name="userList[0].name" value="哈哈"/>
		性別：<input type="text" name="userList[0].gender" value="男"/>
		<hr/>
		
		姓名：<input type="text" name="userList[1].name" value="呵呵"/>
		性別：<input type="text" name="userList[1].gender" value="男"/>
		<hr/>

		姓名：<input type="text" name="userList[2].name" value="嘻嘻"/>
		性別：<input type="text" name="userList[2].gender" value="女"/>
		<hr/>
		
		<input type="submit" value="批量註冊"/>
		
	</form>
