tiger版本仅提供了(jin)dao/service部分Q所以如果你希望在view 查询的安全性方面得到加强，可参考bba96 2.0其中的webwork view部分Q权限部分也没有包含在tiger中，希望快把包括例子的权限部分q移q来Q但q需要一Ҏ(gu)_(d)最q在忙一个CMS的品，旉不够用啊…?/p>

java doc 如下
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:
- Look for message in aClass' class hierarchy.
- Look for the message in a resource bundle for aClass
- If not found, look for the message in a resource bundle for any implemented interface
- If not found, traverse up the Class' hierarchy and repeat from the first sub-step
- If not found and aClass is a ModelDriven Action, then look for message in the model's class hierarchy (repeat sub-steps listed above).
- 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 user.address.state, then it will attempt to see if "user" can be resolved into an object. If so, repeat the entire process fromthe beginning with the object's class as aClass and "address.state" as the message key.
- If not found, look for the message in aClass' package hierarchy.
- If still not found, look for the message in the default resource bundles.
- Return defaultMessage
主要是查找resource bundleQ下面说明一?BR>1. 先查找该classQ一般我们是在action调用Q就是该action对应的class?jin)?j)对应的properties文gQ找不到再去扑֯应的接口Q找不到再去从该class的承树(wi)上去重复前面的步骤?BR>2. 如果是ModelDriverQ以上找不到再以model的class去重?的步?BR>3.l箋找，如果key是符合ognl表达式还以ognl表达式去解析c，如果能找到类Q还以以上的步骤L?BR>4. q找不到Q就从根据package以及(qing)package的承树(wi)LQ这q包括了(jin)该class的承树(wi)所有的class的package?wi)（q一步存在了(jin)太多的重复查扑ַ作，因ؓ(f)很多package都是相同的）(j)
5 使用默认的resource bundle
java.util.ResourceBundle虽然有cacheQ但是wwZ(jin)减少调用getResourceBundleҎ(gu)Q也l护?jin)一个miss的hashsetQ找不到的bundle name׃q去Q那么每一ơ查N同步?jin)这个missQ如果很多次查找Q开销也是很大的?BR>
我就举一个例子，pW四步查找package?wi)好?BR>
for (Class clazz = aClass;
(clazz != null) && !clazz.equals(Object.class);
clazz = clazz.getSuperclass()) {
String basePackageName = clazz.getName();
while (basePackageName.lastIndexOf('.') != -1) {
basePackageName = basePackageName.substring(0, basePackageName.lastIndexOf('.'));
String packageName = basePackageName + ".package";
msg = getMessage(packageName, locale, aTextName, valueStack, args);
if (msg != null) {
return msg;
}
if (indexedTextName != null) {
msg = getMessage(packageName, locale, indexedTextName, valueStack, args);
if (msg != null) {
return msg;
}
}
}
}
假设你的actionl承?wi)是q样
com.bba96.core.webwork.actions.DefaultActionSupport
com.xxxx.web.actions.XXXActionSupport
com.xxxx.web.user.actions.UserAction
com.xxxx.web.user.ViewUserAction
且不说ww没有判断是否是com.opensymphony.xwork.ActionSupport或者ww的接口就停止Q光是自ql承?wi)，?+3+3+3=13ơ，再加上往上的l承?wi)以及(qing)对应的接口Qcom.opensymphony.xwork.ActionSupport以及(qing)Action, Validateable, ValidationAware, TextProvider, LocaleProvider, Serializable, ContinuableObject的接口，查找ơ数过30ơ甚x多，q里的每一ơ都有一个同步miss的过E，开销相当大?BR>
如果你的key所在的resource bundle没有对应到合适的class或packageӞ例如说放在了(jin)default bundle中，ww?x)浪费很多时间。这U情况下Q我在没有ƈ发的时候测?jin)一下，一ơgetText大概耗时40ms左右
所以在实际应用我们应该避免q种情况出现Q要不让resource bundle一一对应classQ要不就自己实现一个简单的getTextQ其实要是ww的ActionSupport的textProvider允许改变最好了(jin)?/P>

Get Up And Running Quick
Example: (1) enter the example/simple or emample/book folder.
NOTE:all following operation is under the folder you entered
(2) copy your JDBC driver (default mysql) to the lib directory
-- webapps\ROOT\WEB-INF\lib
(3) edit hibernate.properties for database info (default mysql)
-- src\main\java\hibernate.properties
(4) run "ant"
(5) create database via the sql script generated at database\schema-export.sql
(6) edit applicationContext.xml for database info (default mysql)
-- webapps\ROOT\WEB-INF\applicationContext.xml (line 5 - 21)
(7) start server and see this example
