Spring Interceptors
To add an interceptor to your application, do the following;
Add the following to your application-context.xml file;
<context:component-scan base-package="com.test" /> <mvc:annotation-driven/> <mvc:interceptors> <bean .... /> </mvc:interceptors>

Spring-EL Expressions
To enable spring security EL expressions, add the following to the <http> element in your application-security.xml file;
use-expressions="true"
A few gotcha’s when enabling this; each of your <intercept-url … role=”ROLE_USER” needs to be changed to role=”hasRole(‘ROLE_USER’)
Also – the following exception will be thrown unless you change ‘IS_AUTHENTICATED_ANONYMOUSLY’ to ‘permitAll’;
Failed to evaluate expression 'IS_AUTHENTICATED_ANONYMOUSLY'
In your JSP pages the following can be used for securing portions of pages;
<sec:authorize access="hasRole('ROLE_MANAGER')"> ... </sec:authorize>

Spring – c:foreach and hibernate’s maps / lists
iterating over a list / set can be done via;
<c:forEach items=”${job.jobPhotos}” var=”photo” varStatus=”idx”>
<form:hidden path=”jobPhotos[${idx.index}].id” />
Iterating over a map can be done via;
<c:forEach items=”${job.jobPhotos}” var=”current”>
<form:hidden path=”jobPhotos[${current.key}].id” />
${current.key} and ${current.value.id} are equilivant (both equate to the ID of the row being iterated over)

Spring Date / time parsing
Here’s a few ways to format datetime / date / time values via spring;
Use the @DateTimeFormat annotation to specify the format Date values need to be displayed in. Style comes in a few flavours (see the link at the bottom), and pattern uses the standard java pattern for formatting.

jQuery Book – Basics through to Performance Optimisations
A few things to note;
- When using selectors with ID tags, use $(‘#abc’).find(‘.defg .higk’); instead of $(‘#abc .defg .higk’);
- Also use named functions more-so than anonymous ones;
var PI = {onReady : function() {$(‘#magic’).click(PI.candyMtn);$(‘#happiness’).load(PI.url + ‘ #unicorns’, PI.unicornCb);},candyMtn : function(e) {$(‘#yayeffects’).slideUp(PI.slideCb);},slideCb : function() { … },unicornCb : function() { … }};$(document).ready(PI.onReady);
- Plugin creation;
// defining the plugin
(function($){
$.fn.hoverClass = function(c) {
return this.hover(
function() { $(this).toggleClass(c); };
};
}(jQuery);// using the plugin
$(‘li’).hoverClass(‘hover’); - see here for signs of poorly written plugins; http://remysharp.com/2010/06/03/signs-of-a-poorly-written-jquery-plugin/

Curvy Corners
This might be worth implementing for sites which have curvy-corners using CSS3 yet not quite there yet on IE…
