Internationalization of placeholders in Spring - spring

Question

I can not find the way to internationalize the text inside a placeholder like I do with regular text. I would like to place my internationalization in:
input type="text" class="form-control" name="s" placeHolder="Search Hobbies"
with input type="text" class="form-control" name="s" placeHolder="ctrlpanel.search.placeholder"
ctrlpanel.search.placeholder=Search Hobbies
Right now, in my JSP I include the tag
<%# page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%# taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<%# taglib prefix="fmt" uri="http://java.sun.com/jsp/jstl/fmt"%>
<%# taglib prefix="spring" uri="http://www.springframework.org/tags" %>
<c:set var="contextRoot" value="${pageContext.request.contextPath}" />
<c:url var="search" value="/search" />
<hr/>
<div class="row">
<div class="col-md-8 col-md-offset-2">
<form action="${search}" method="post">
<input type="hidden" name="${_csrf.parameterName}"
value="${_csrf.token}" />
<div class="input-group input-group-lg">
<input type="text" class="form-control" name="s" placeHolder="Search Hobbies">
<span class="input-group-btn">
<button id="search-button" class="btn btn-primary" type="submit">
<spring:message code="ctrlpanel.find.button" text="default text" />
</button>
</span>
</div>
</form>
</div>
</div>
My configuration works fine:
package com.caveofprogramming.configuration;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.LocaleResolver;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.i18n.LocaleChangeInterceptor;
import org.springframework.web.servlet.i18n.SessionLocaleResolver;
import java.util.Locale;
#Configuration
public class SpringMvcConfiguration extends WebMvcConfigurerAdapter {
#Bean
public LocaleResolver localeResolver(){
SessionLocaleResolver sessionLocaleResolver = new SessionLocaleResolver();
sessionLocaleResolver.setDefaultLocale(new Locale("es", "ES"));
//sessionLocaleResolver.setDefaultLocale(Locale.US);
return sessionLocaleResolver;
}
#Bean
LocaleChangeInterceptor localeChangeInterceptor(){
LocaleChangeInterceptor localeChangeInterceptor = new LocaleChangeInterceptor();
localeChangeInterceptor.setParamName("lang");
return localeChangeInterceptor;
}
#Override
public void addInterceptors(InterceptorRegistry interceptorRegistry){
interceptorRegistry.addInterceptor(localeChangeInterceptor());
}
}
Since this does not work.
<input type="text" class="form-control" name="s" placeHolder="<spring:message code="ctrlpanel.search.placeholder"/>">

Answer 1

Use var attribute of spring:message which is used when binding the result to the page, request, session or application scope.
<spring:message code="ctrlpanel.search.placeholder" var="searchPlaceholder"/>
And then update your input field like this:
<input type="text" class="form-control" name="s" placeHolder="${searchPlaceholder}">
