[JAVA] Spring taglib: form notes

A brief note about Spring jsp form tags

Initial setting(?)

Add the following to the jsp file to use

<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form %>

The beginning of the added file is below

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@ taglib prefix="form" uri="http://www.springframework.org/tags/form %>

Basic shape

The basic form of the form tag is as follows

View page

HogeForm.java

//abridgement

public class HogeForm {
	private String hoge;
	
	//Getter and setter omitted
}

HogeController.java

//Basic notation is omitted to some extent
public String hogeForm(Model model) {
	HogeForm form = new HogeForm();
	//Set the initial value you want to display on the form
	form.setHoge("foo");
	return "page";
}

page.jsp

<form:form modelAttribute="checkForm">
    <form:input path="hoge" />
    <input type="submit" />
</form:form>

Receiving the form

HogeController.java

public Stiring hogeForm(@ModelAttribute HogeForm form, Model model) {
	//Set to message from the received value
	model.setAttribute("message", form.getHoge());
	return "result";
}

result.jsp

<!--Omit the basics-->
<!--Display message-->
<p>${ message }</p>
	

The above is the basic basic form
