【SpringMVC】在业务控制方法中收集数组与List<JavaBean>参数（十五）

1）批量删除用户

@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";}}

2）批量注册用户

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","批量增加用户成功");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.java

<form action="${pageContext.request.contextPath}/user/addAll.action" method="POST">  姓名：<input type="text" name="userList[0].name" value="哈哈"/>性别：<input type="text" name="userList[0].gender" value="男"/><hr/>姓名：<input type="text" name="userList[1].name" value="呵呵"/>性别：<input type="text" name="userList[1].gender" value="男"/><hr/> 姓名：<input type="text" name="userList[2].name" value="嘻嘻"/>性别：<input type="text" name="userList[2].gender" value="女"/><hr/><input type="submit" value="批量注册"/></form>
