Spring & Tomcat – custom errors

In spending a few hours on trying to get the error-page tag in tomcat’s web.xml working, i’ve found a better way to do it – one which uses spring to take on exception handling rather than Tomcat itself – something which also lets spring give the error-page visibility on other view-objects and business-rules.

Simple enough to implement and works wonderfully! 🙂

Eg;

<bean>
<property name="exceptionMappings">
<map>
<entry key="project.exception.RecordNotFoundException" value="recordNotFoundException" />
</map></property>
</bean>

Add the following to your application-context.xml file;

<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>

A few other useful links;

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)
