我的要求是根据所选值(选择表格)返回视图
view.jsp的:
<form method="post" action="/aaa">
<select id="attr1" name="attr1">
<option value="1">A</option>
<option value="2">B</option>
</select>
<input type="submit" value="submit" />
</form>
如果选择的值是A(1),则view1是要显示的视图,否则显示view2。
控制器方法:
@RequestMapping(value = "/aaa", method = RequestMethod.POST)
public ModelAndview methodName ( HttpServletRequest request,
HttpServletResponse response){
attribute=request.getParameter("attr1");
if (attribute==1) return new ModelAndView("view1")
else if (attribute==2) return new ModelAndView ("view2")
}
我该怎么办? 感谢。

完全可以使用多个视图。
考虑HTML:
<select id="attr1" name="attr1">
<option value="1">A</option>
<option value="2">B</option>
</select>
然后控制器方法应该是:
@RequestMapping(value = "/aaa", method = RequestMethod.POST)
public ModelAndView methodName(@RequestParam(value = "attr1") int attribute) {
if (attribute == 1) {
return new ModelAndView("view1");
}
else if (attribute == 2) {
return new ModelAndView("view2");
}
else {
return null; // Empty 200 OK just to be sure if other attr is received
}
}
