Example 8 with ModelDriven

use of com.opensymphony.xwork2.ModelDriven in project struts by apache.

the class StrutsLocalizedTextProvider method findText.

/**
 * <p>
 * Finds a localized text message for the given key, aTextName. Both the key and the message
 * itself is evaluated as required.  The following algorithm is used to find the requested
 * message:
 * </p>
 *
 * <ol>
 * <li>If {@link #searchDefaultBundlesFirst} is <code>true</code>, look for the message in the default resource bundles first.</li>
 * <li>Look for message in aClass' class hierarchy.
 * <ol>
 * <li>Look for the message in a resource bundle for aClass</li>
 * <li>If not found, look for the message in a resource bundle for any implemented interface</li>
 * <li>If not found, traverse up the Class' hierarchy and repeat from the first sub-step</li>
 * </ol></li>
 * <li>If not found and aClass is a {@link ModelDriven} Action, then look for message in
 * the model's class hierarchy (repeat sub-steps listed above).</li>
 * <li>If not found, look for message in child property.  This is determined by evaluating
 * the message key as an OGNL expression.  For example, if the key is
 * <i>user.address.state</i>, then it will attempt to see if "user" can be resolved into an
 * object.  If so, repeat the entire process from the beginning with the object's class as
 * aClass and "address.state" as the message key.</li>
 * <li>If not found, look for the message in aClass' package hierarchy.</li>
 * <li>If still not found, look for the message in the default resource bundles
 * (Note: the lookup is not repeated again if {@link #searchDefaultBundlesFirst} was <code>true</code>).</li>
 * <li>Return defaultMessage</li>
 * </ol>
 *
 * <p>
 * When looking for the message, if the key indexes a collection (e.g. user.phone[0]) and a
 * message for that specific key cannot be found, the general form will also be looked up
 * (i.e. user.phone[*]).
 * </p>
 *
 * <p>
 * If a message is found, it will also be interpolated.  Anything within <code>${...}</code>
 * will be treated as an OGNL expression and evaluated as such.
 * </p>
 *
 * <p>
 * If a message is <b>not</b> found a DEBUG level log warning will be logged.
 * </p>
 *
 * @param aClass         the class whose name to use as the start point for the search
 * @param aTextName      the key to find the text message for
 * @param locale         the locale the message should be for
 * @param defaultMessage the message to be returned if no text message can be found in any
 *                       resource bundle
 * @param args           arguments
 * @param valueStack     the value stack to use to evaluate expressions instead of the
 *                       one in the ActionContext ThreadLocal
 * @return the localized text, or null if none can be found and no defaultMessage is provided
