If I have a HTML in a <form> like this:
<input type="text" value="someValue1" name="myValues"/>
<input type="text" value="someValue2" name="myValues"/>
<input type="text" value="someValue3" name="myValues"/>
<input type="text" value="someValue4" name="myValues"/>
I know that in servlets I am able to get values using:
String[] values = request.getParameterValues("myValues");
How can I do something similar using Spring MVC?
The parameters are passed as arguments to the method bound to your controller
@RequestMapping(value = "/foo", method = RequestMethod.POST) // or GET
public String foo(@RequestParam("myValues") String[] myValues) {
// Processing
return "view";
}
You already have HttpServletRequest request in spring web MVC. We can get it using the same i.e. using
String[] values = request.getParameterValues("myValues");
Also you can use ServletRequestUtils to read request parameters in Spring like :
String[] values = ServletRequestUtils.getRequiredStringParameters(request, "myValues");
See how to access Http request : Spring 3 MVC accessing HttpRequest from controller
For annotation based approach: See Alex's answer.
In jsp i would like:
<%@ taglib uri="http://www.springframework.org/tags/form" prefix="form"%> <!-- Add taglib in beginning of the page.-->
<!-- In body the html -->
<form:form action="/foo" method="post" commandName="MyValues">
<input type="text" value="someValue1" name="myValues1"/>
<input type="text" value="someValue2" name="myValues2"/>
<input type="text" value="someValue3" name="myValues3"/>
<input type="text" value="someValue4" name="myValues4"/>
</form:form>
See references in section 13.9. Using Spring's form tag library tag explains, in link: http://static.springsource.org/spring/docs/2.0.x/reference/mvc.html
The controller is part of the same friend Alex answered.
