未找到 UsernamePasswordAuthenticationToken 的 AuthenticationProvider [英] No AuthenticationProvider found for UsernamePasswordAuthenticationToken

问题描述

我的 web.xml 配置是

my web.xml config is

<filter>
        <filter-name>springSecurityFilterChain</filter-name>
        <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class>
    </filter>

    <filter-mapping>
        <filter-name>springSecurityFilterChain</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

这是我的安全配置

    <intercept-url pattern="/*" access="ROLE_USER" />
    <intercept-url pattern="/*.ico"  filters="none" />


</http>

 <beans:bean id="customAuthenticationProvider" class="net.spring3.provider.MyAuthProvider"  />

    <authentication-manager>

        <authentication-provider ref="customAuthenticationProvider" /> 

    </authentication-manager>

这是我的 customAuthProvider 类

Here is my customAuthProvider class

public class MyAuthProvider implements AuthenticationProvider  {


    @Override
    public boolean supports(Class<? extends Object> arg0) {
        // TODO Auto-generated method stub
        return false;
    }


     @SuppressWarnings("serial")
        private static Map<String, String> SIMPLE_USERS = new HashMap<String, String>(2) {{
            put("joe", "joe");
            put("bob", "bob");
        }};

        @SuppressWarnings("serial" )
        private static List<GrantedAuthority> AUTHORITIES = new ArrayList<GrantedAuthority>(1) {{
            add(new GrantedAuthorityImpl("ROLE_USER"));
        }};

        @Override
        public Authentication authenticate(Authentication auth) throws AuthenticationException
        {
            // All your user authentication needs
            System.out.println("==Authenticate Me==");
            if (SIMPLE_USERS.containsKey(auth.getPrincipal()) 
                && SIMPLE_USERS.get(auth.getPrincipal()).equals(auth.getCredentials()))
            {
                return new UsernamePasswordAuthenticationToken(auth.getName(), auth.getCredentials(), AUTHORITIES);
            }
            throw new BadCredentialsException("Username/Password does not match for " + auth.getPrincipal());
        }




}

页面显示登录表单，当我输入 bob 和 bob 作为 login 时，它抛出以下错误.

The page shows the login form and when I enter bob and bob as login , it throws up the following error.

Your login attempt was not successful, try again.

Reason: No AuthenticationProvider found for org.springframework.security.authentication.UsernamePasswordAuthenticationToken

我检查了所有调试级别的日志，这就是我得到的.

I checked the logs at debug level ALL and here is what I get.

FINE: Request is to process authentication
Nov 17, 2011 5:37:36 AM org.springframework.context.support.AbstractApplicationContext publishEvent
FINEST: Publishing event in Root WebApplicationContext: org.springframework.security.authentication.event.AuthenticationFailureProviderNotFoundEvent[source=org.springframework.security.authentication.UsernamePasswordAuthenticationToken@ffff8dfd: Principal: sd; Credentials: [PROTECTED]; Authenticated: false; Details: org.springframework.security.web.authentication.WebAuthenticationDetails@fffe3f86: RemoteIpAddress: 127.0.0.1; SessionId: x4lg4vtktpw9; Not granted any authorities]

FINE: Authentication request failed: org.springframework.security.authentication.ProviderNotFoundException: No AuthenticationProvider found for org.springframework.security.authentication.UsernamePasswordAuthenticationToken

对此有什么帮助..我在这里做错了什么?

Any help on this..what am I doing wrong here ?

推荐答案

正如您在评论中已经写的，问题是您总是在 supports()false> 您的身份验证提供商的方法.但是不是总是返回 true 你应该检查 authentication 你得到这样的:

As you already wrote in your comment the problem is that you always return false in the supports() method of your autentication provider. But instead of always returning true you should check the authentication you get like this:

public class MyAuthenticationProvider implements AuthenticationProvider, Serializable {

    @Override
    public boolean supports(Class<? extends Object> authentication) {
        return (UsernamePasswordAuthenticationToken.class.isAssignableFrom(authentication));
    }

    // ...
}
