春天 - 安全：登录用户名和密码如何绑定到身份验证提供程序？ [英] Spring - Security : how are login username and password bound to the authentication-provider?

问题描述

我已经了解了如何在xml文件中创建和引用bean，
我需要提供安全性在我的应用程序中使用spring。

我在web.xml中包含了一个自定义的applicationContext-security.xml文件：contextConfigLocation

在这个文件中，我使用

 < intercept-url pattern ='/ **。 'access =IS_AUTHENTICATED_FULLY/> 
  

里面元素。

现在登录的形式为
，如果页面未被授权，则显示我的自定义Login.html页面。

现在针对我面临的问题：

1. 如何指定我的登录表单将其值传递给spring？


2. 使用我自己的身份验证提供程序？

我试过这个：

 < authentication-provider user-service-ref =userDetailsS​​ervice/> 
< beans：bean id =userDetailsS​​erviceclass =com.somepath.CustomAuthenticationProvider> 
< custom-authentication-provider /> 
< / beans：bean> 
  

其中CustomAuthenticationProvider实现了AuthenticationProvider

代码会抛出一个错误：
创建名为'_filterChainProxy'的bean时出错......没有注册UserDetailsS​​ervice

请帮忙
<解决方案1：我如何指定我的登录表单将其值传递给spring？

设置完成后Spring Security的web.xml中的标准Spring Filter，使用由< http> 标签配置的一些默认设置。 AuthenticationProcessingFilter 的实例作为过滤器链的一部分为您创建。

我的默认值 AuthenticationProcessingFilter 设置为将j_username和j_password作为用户名/密码标记。

为了覆盖这个， AuthenticationProcessingFilter通过这样做：

 < bean id =myAuthFilterclass =org.springframework.security。 ui.webapp.AuthenticationProcessingFilter> 
< security：custom-filter position =AUTHENTICATION_PROCESSING_FILTER/><！ - 替换默认值 - > 
  < / bean> 
  

另请参阅AuthenticationProcessingFilter的JavaDoc以获取更多详细信息：

2：如何使用我自己的身份验证提供程序？

使用以下代码：

 < bean id =myAuthenticationProvider class =com.something.MyAuthenticationProvider> 
< security：custom-authentication-provider /> 
< / bean> 
  

< security：custom-authentication-provider /> 是Spring的标签，它知道这是一个自定义提供程序，Authentication Manager应该在其提供程序链中使用它。

3：关于问题与抛出'_filterChainProxy'的代码....没有UserDetailsS​​ervice注册...'

是 com.somepath.CustomAuthenticationProvider 实现UserDetailService接口？

I am new to spring and spring security,

I have understood how beans are created and referenced in the xml files, I need to provide security using spring into my application.

I included a custom applicationContext-security.xml file in my web.xml : contextConfigLocation

in this file, I have intercepted url patterns using

<intercept-url pattern='/**.something' access="IS_AUTHENTICATED_FULLY"/>

inside element.

I have set the form for login as now, if a page is not authorised it shows me my custom Login.html page.

Now for the issues I am facing:

1. How do I specify my login form to pass its value to spring ?
2. How do I use my own authentication-provider ?

I tried this:

<authentication-provider user-service-ref="userDetailsService"/>
<beans:bean id = "userDetailsService" class ="com.somepath.CustomAuthenticationProvider">
        <custom-authentication-provider/>
    </beans:bean>

where CustomAuthenticationProvider implements AuthenticationProvider

but the code throws an error: Error creating bean with name '_filterChainProxy' .... No UserDetailsService registered

Please help

解决方案

1: How do I specify my login form to pass its value to spring ?

After you setup your standard Spring Filter in web.xml for Spring Security, using some of the default settings configured by the <http> tag. An instance of AuthenticationProcessingFilter is created for you as part of the chain of filters.

My default the AuthenticationProcessingFilter is set up to read j_username and j_password as the username / password token.

In order to override this, replace your customize AuthenticationProcessingFilter over the default one by doing this:

<bean id="myAuthFilter" class="org.springframework.security.ui.webapp.AuthenticationProcessingFilter" >
<security:custom-filter position="AUTHENTICATION_PROCESSING_FILTER"/><!–-replace the default one-–>
  <property name="usernameParameter" value="myUsername"/><!-- myUsername is the name of the input tag where user enter their username on the HTML page -->
  <property name="passwordParameter" value="myPassword" /><!–- myPassword is the name of the input tag where user enter their password on the HTML page -–>
</bean>

See also the JavaDoc of AuthenticationProcessingFilter for more details: http://static.springsource.org/spring-security/site/apidocs/org/springframework/security/ui/webapp/AuthenticationProcessingFilter.html

2: How do I use my own authentication-provider?

Using the following code:

<bean id="myAuthenticationProvider" class="com.something.MyAuthenticationProvider">
    <security:custom-authentication-provider />
</bean>

<security:custom-authentication-provider /> is the tag that let's spring knows this is a custom provider and the Authentication Manager should use it in its provider chain.

3: Regarding the issue with the code throwing '_filterChainProxy' .... No UserDetailsService registered...'

Is com.somepath.CustomAuthenticationProvider implementing the UserDetailService interface?
