I wonder why I have to add "classpath:" always int he resourcelocations mapping for Spring, is this best practice?
Currently my project is setup like this, but I if I remove the "classpath", it does not find anything (and also I cannot provide a proper direct link). For integating bootstrap, I even had to use "webjars-locator" to make webjars accessible (due to missing transparency).
Can anyone explain, why classpath is required (and no direct link), and how I can find or restrucutre the project to make it work properly?
ResourceHandlers:
#Override
public void addResourceHandlers(final ResourceHandlerRegistry registry) {
registry.addResourceHandler(
"/webjars/**",
"/img/**",
"/css/**",
"/js/**")
.addResourceLocations(
"classpath:/META-INF/resources/webjars/",
"classpath:/static/img/",
"classpath:/static/css/",
"classpath:/static/js/");
}

It is normal to use classpath. If you want to additionally load resources from root path use
{"/", "classpath:/META-INF/resources/webjars/" ...}

i'm trying to use spring security. I created two users in memory admin and users.
auth.inMemoryAuthentication().withUser("admin").password("admin").roles("ADMIN");
auth.inMemoryAuthentication().withUser("user").password("user").roles("USER");
This is my pom.xml:
<dependency>
<groupId>org.thymeleaf.extras</groupId>
<artifactId>thymeleaf-extras-springsecurity4</artifactId>
</dependency>
and this is my html page:

<div sec:authorize="hasRole('ROLE_ADMIN')">Only for admin</div>
//code ...
I would like that only the admin sees that div, but when i logged as a user, the div above appears, or it should be disappear. can you tell me where is the probleme ? thank you.
Could you replace in thymeleaf this
<div sec:authorize="hasRole('ROLE_ADMIN')">Only for admin</div>
with the following
<div sec:authorize="hasAuthority('ADMIN')">Only for admin</div>
and let me know if it works for you.
make sure that you are using spring security 4, if you don't change your thymeleaf-extras-springsecurity for the correct one
after searching and trying to understand the problem i found out that there is a problem with the dialect
you can see here how to add the dialect:
How do I add Thymeleaf SpringSecurityDialect to spring boot
tl;dr
add this to your config
#Bean
public SpringSecurityDialect securityDialect() {
return new SpringSecurityDialect();
}
I have the following fragment. I'm trying to extend the base fragment "head" with the open graph tags... but the rendered page contains only tags from fragments/head, with the og ones.
How can I add more tags to a fragment?
<head th:include="fragments/head :: head">
<!-- You can use Open Graph tags -->
<meta property="og:url" th:content="${url}" />
<meta property="og:type" content="website" />
<meta property="og:title" content="GUApp" />
<meta property="og:description" th:content="${description}" />
<!--<meta property="og:image" content="http://www.your-domain.com/path/image.jpg" />-->
</head>
<head th:fragment="head" xmlns="http://www.w3.org/1999/xhtml" xmlns:th="http://www.thymeleaf.org">
....
</head>
The easiest option is to pass additional tags as in Flexible layouts documentation demo.
Thanks to fragment expressions, we can specify parameters for
fragments that are not texts, numbers, bean objects… but instead
fragments of markup.
This allows us to create our fragments in a way such that they can be
enriched with markup coming from the calling templates, resulting in a
very flexible template layout mechanism.

I just created a new Spring Boot v1.5 project and facing issue where Thymeleaf Layout Dialect is not working.
I have the dependencies in my build.gradle and its on the classpath.
compile group: 'nz.net.ultraq.thymeleaf', name: 'thymeleaf-layout-dialect', version: '2.1.2'
I have the following layout file
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout">
<head>
<meta charset="UTF-8" />
<title>Default Template</title>
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1.0" />
<meta name="author" content="" />
<meta name="description" content="" />
<meta name="title" content="" />
<link rel="stylesheet" media="screen" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" />
</head>
<body>
<!-- header -->
<header th:include="shared/nav-menu :: menu-admin" />
<!-- page content -->
<th:block>
<section layout:fragment="content"></section>
</th:block>
</body>
</html>
And file with content:
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:th="http://www.thymeleaf.org"
xmlns:layout="http://www.ultraq.net.nz/thymeleaf/layout"
layout:decorator="default">
<head>
<title>Parameter Manager</title>
</head>
<body>
<section layout:fragment="content">
<h2>OMG I am on the page!</h2>
</section>
</body>
</html>
The HTML output is content.html file. It is not working as intended. The header and navigation menu should be part of the HTML output. Also the is in the page source which should not be the case.
Apparently the latest version of Thymeleaf Layout Dialect doesn't work with Spring Boot 1.5. Using version 1.2.9 and it works as expected.
compile group: 'nz.net.ultraq.thymeleaf', name: 'thymeleaf-layout-dialect', version: '1.2.9'
I am working on a Spring MVC application that use FreeMarker for my views.
I am absolutly new in FreeMarker and I have the following problem: in my projct I have 3 files that have to be assemblet togheter into a single page.
So I have:
1) header.ftl representing the header of all my pages, somthing like:
<!DOCTYPE html>
<!--[if IE 8]><html class="no-js is-ie8"><![endif]-->
<!--[if gt IE 8]><!--><html class="no-js"><!--<![endif]-->
<head>
<meta charset="utf-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">
<meta name="viewport" content="width=device-width, initial-scale=1">
<title>Registrazione - MY WEBSITE</title>
<meta name="robots" content="noindex,nofollow">
<link rel="stylesheet" href="resources/css/webfont.css">
<link rel="stylesheet" href="resources/bootstrap/css/bootstrap.min.css">
<link rel="stylesheet" href="resources/bootstrap/css/bootstrap-theme.min.css">
<link rel="stylesheet" href="resources/plugins/bs-select/bootstrap-select.min.css">
<link rel="stylesheet" href="resources/plugins/bs-dialog/bootstrap-dialog.min.css">
<link rel="stylesheet" href="resources/css/style.css" />
</head>
<body id="main">
<!-- versione per popup. non prendere in considerazione -->
<!--
<div class="container page-header">
<h1>MY WEBSITE</h1>
</div>
2) footer.ftl representing the footer of all my pages:
<script src="assets/bootstrap/js/bootstrap.min.js"></script>
<script src="assets/plugins/bs-select/bootstrap-select.min.js"></script>
<script src="assets/plugins/bs-select/i18n/defaults-it_IT.min.js"></script>
<script src="assets/plugins/bs-dialog/bootstrap-dialog.min.js"></script>
<script src="assets/plugins/jq-form-validation/jquery.validation.js"></script>
<script src="assets/js/functions.lib.js"></script>
<script src="assets/js/form-validation.js"></script>
</body>
</html>
3) Then I have my specific page (named myPage.ftl that represent only the content, something like this:
<h1>This is the content</h1>
<p>Some inforamation</p>
The header.ftl and the footer.ftl are into this directory **\WEB-INF\freemarker\layout** of my project.
So my problem is: how can I import the header.ftl content above the content of the myPage.ftl and the footer.ftl under the content of myPage.ftl page?
I did this using user-defined macros for page layouts, e.g. let's call your layout standardPage.ftl:
<#macro standardPage title="">
<!DOCTYPE html>
<html lang="en">
<head>
<title>${title}</title>
</head>
<body>
<#include "/include/header.ftl">
<#nested/>
<#include "/include/footer.ftl">
</body>
</html>
</#macro>
Then you can call this macro in each of your pages, e.g. homePage.ftl:
<#include "/pages/standardPage.ftl" />
<#standardPage title="Home">
<h1>Home Page</h1>
<p>This bit replaces the nested tag in the layout</p>
</#standardPage>
I like clean code and I'm sure most developers do. I am coming across an issue where my Meta tags are all appearing on ONE line all together and not on separate lines.
I have a file called "client.master" and here is code for the header:
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" />
<meta name="apple-mobile-web-app-capable" content="yes" />
<meta name="apple-mobile-web-app-status-bar-style" content="default" />
<meta name="format-detection" content="telephone=no" />
<script src="/scripts/script1.min.js" type="text/javascript"></script>
<script src="/scripts/script2.min.js" type="text/javascript"></script>
<link rel="apple-touch-icon" href="/images/home-screen.png" />
<link rel="apple-touch-startup-image" href="/images/home-startup.png" />
<link href="/css/thirdparty/xxxxx.min.css" type="text/css" rel="stylesheet" />
<link href="/css/design.css" type="text/css" rel="stylesheet" />
<asp:ContentPlaceHolder ID="headContent" runat="server">
</asp:ContentPlaceHolder>
</head>
That looks very clean and nice. However, when I view the source of the page, the output shows the <meta> tags and the <link> tags all on one line. The script tags are not.
Here is the output of my code:
<!DOCTYPE html>
<html>
<head><meta http-equiv="Content-Type" content="text/html; charset=utf-8" /><meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no" /><meta name="apple-mobile-web-app-capable" content="yes" /><meta name="apple-mobile-web-app-status-bar-style" content="default" /><meta name="format-detection" content="telephone=no" />
<script src="/scripts/script1.min.js" type="text/javascript"></script>
<script src="/scripts/script2.min.js" type="text/javascript"></script>
<link rel="apple-touch-icon" href="/images/home-screen.png" /><link rel="apple-touch-startup-image" href="/images/home-startup.png" /><link href="/css/thirdparty/xxxxx.min.css" type="text/css" rel="stylesheet" /><link href="/css/design.css" type="text/css" rel="stylesheet" />
<title>
Login
</title></head>
Notice the <meta> and <link> tags are both on a single line AND the <title> tag has line breaks.
Here is the HTML for the default.aspx page for the Title:
<asp:Content ID="title" runat="server" ContentPlaceHolderID="title">
Login
</asp:Content>
My assumption is because the <meta> tags and <link> tags are self enclosed and the <script> tags end with </script>.
Is the only way to resolve this issue to close my <meta> tags with </meta>. Which way is to be considered the standard when closing meta and link tags? or script tags?
Thanks in advance for your help!
If you really want to follow the spec, link and meta are void elements, they can't have a closing tag, if your DOCTYPE is HTML5, you can use the selfclosing tag <meta ..../> but the default way would be to use it only as a start tag, that is a correct conforming use as empty elements don't need an end tag (void ones, as I said, can't have it).
Script is not a void element, but is an empty one, so you can use only the start tag, the self-closing tag or both start and end tags.
Note that for an element to have a content model of type empty really means it may be empty, not that it should; that would probably be what it is called void.
As to why the asp parser does that to your metas, I can't think of a reason. I understand your preference for clean code, but if it is of any help, try to think that at least that bug contributes to a filesize decrease :o)
Bear in mind that all of this applies to HTML5, XHTML treats void and empty models differently.
