• 编写资源文件，Acegi的DaoAuthenticationProvider使用了如下的资源Key

AbstractUserDetailsAuthenticationProvider.badCredentials=自定消息
AbstractUserDetailsAuthenticationProvider.onlySupports=自定消息
AbstractUserDetailsAuthenticationProvider.locked=自定消息 account was locked
AbstractUserDetailsAuthenticationProvider.disabled=自定消息account was disabled
AbstractUserDetailsAuthenticationProvider.expired=自定消息
AbstractUserDetailsAuthenticationProvider.credentialsExpired=自定消息

• 定义资源Bean

    <bean id="messageSource"
        class="org.springframework.context.support.ResourceBundleMessageSource">
    <property name="basename">
            <value>资源文件（包名+资源文件名）</value>
        </property>
    </bean>

• 将资源Bean注入到DaoAuthenticationProvider

1    <bean id="daoAuthenticationProvider"
2        class="org.acegisecurity.providers.dao.DaoAuthenticationProvider">
3        <property name="userDetailsService">
4            <ref local="inMemoryDaoImpl" />
5        </property>
6        <property name="messageSource">
7            <ref bean="messageSource" />
8        </property>
9    </bean>
