spring2.0,multiactioncontroller 일때 수동 validataion하기..(유지보수 프로젝트를 여행하는 히치하이커를 위한 안내서)

spring2.0  그리고 multiactioncontroller환경일때 수동으로 validation하는방법


in controller...

public  ModelAndView makePost(HttpServletRequest request,HttpServletResponse response) throws Exception{

Map model = new HashMap();

MakeCommand command = new MakeCommand();

bind(request, command);

BindingResult result = new BeanPropertyBindingResult( command, "command");

result.addError(new FieldError("row", "api_name", command.getApi_name(), false,null,null,"이름을 입력하세요"));

   

        //수동으로 BindingResult 추가 

        model.put("org.springframework.validation.BindingResult.command",result);

    if(result.hasErrors()){

    model.put("command",command);

    return new ModelAndView("apis/make",model);

    }

    

return new ModelAndView("apis/make",model);

}

in jsp...

<form:form action="${ctx }/apis/makePost.htm" method="post" commandName="command" >

api name

<form:input path="api_name" />

<form:errors path="api_name" />

        <input type="submit" value="save" /> 

</form:form>
