SpringMVC获取表单批量提交数据

关键点：封装一个JavaBean的List

原始JavaBeanpublic class Person {    //省略getter、setter,Serialiable接口实现，toString(),equals(),HashCode()    private String username;    private String password;    private String money;}封装JavaBean的另一个Beanpublic class PersonListModel {    private List<Person> personList;    //省略相关setter、getter}//处理方法@RequestMapping(value="/listPerson.do",method=RequestMethod.GET)public ModelAndView listPersonGET() {    //得到所有Person，封装至Model，供前台显示    List<Person> list = personService.getAllPersons();    ModelAndView mav = new ModelAndView("person/listPerson"); //设置视图名    mav.addObject("list", list);      return mav;}表单jsp页面,name值需要和Controller层接收参数中的JavaBean要一致，如这里的：personList。<form action="${bastPath}/person/listPerson.do" method="post"><c:forEach items="${list}" var="person" varStatus="listIndex"  >  <br/>${person.username}<br/>  <input name="personList[${listIndex.index}].money" type="text"  value="person.money"/></c:forEach>   <input name="submit" value="提交"></form>//使用参数PersonListModel personModel获取jsp页面表单批量提交的数据@RequestMapping(value="/listPerson.do",method=RequestMethod.POST)public ModelAndView listPersonPOST(PersonListModel personModel) {    //于是表单中的personList就会set给PersonListModel 中的字段personList    List<Person> personList = personModel.getPersonList();    for(Person person:personList ) {   //批量修改对象的某个属性        personService.updatePerson(person.money);    }}
