如何在jsp中为spring security auth异常显示自定义错误消息 [英] how to display custom error message in jsp for spring security auth exception

问题描述

我想在jsp中显示spring security认证异常的自定义错误信息.

I want to display custom error message in jsp for spring security authentication exceptions.

如果用户名或密码错误，

For wrong username or password,

spring displays : Bad credentials
what I need     : Username/Password entered is incorrect.

如果用户被禁用，

spring displays : User is disabled
what I need     : Your account is diabled, please contact administrator.

我是否需要为此重写 AuthenticationProcessingFilter ?或者我可以在jsp本身中做一些事情来找到身份验证异常密钥并显示不同的消息

Do I need to override AuthenticationProcessingFilter just for this ? or else can I do something in jsp itself to find the authentication exception key and display different message

推荐答案

重新定义 spring security jar 中 messages.properties 中的属性.例如添加到类路径 myMessages.properties 并将消息源添加到上下文:

Redefine the properties in messages.properties inside spring security jar. For example add to the classpath myMessages.properties and add a message source to the context:

AbstractUserDetailsAuthenticationProvider.badCredentials=Username/Password entered is incorrect.
AbstractUserDetailsAuthenticationProvider.disabled=Your account is diabled, please contact administrator.

在萨尔文·弗朗西斯:

1. 将 myMessages.properties 添加到 WEB-INF/classes 内的 WAR 文件中.
2. 将此bean添加到spring上下文配置文件

消息源 Bean

<bean id="messageSource"   
    class="org.springframework.context.support.ResourceBundleMessageSource">  
    <property name="basenames">  
        <list>
            <value>myMessages</value>
        </list>
    </property>
</bean>
