找不到UsernamePasswordAuthenticationToken的AuthenticationProvider [英] No AuthenticationProvider found for UsernamePasswordAuthenticationToken

问题描述

我的web.xml配置

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());
        }




}

该页面显示登录表单，当我输入bob和bob作为登录时，它会抛出以下错误。

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

<我在调试级别ALL检查了日志，这是我得到的。

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

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

有关此...的任何帮助我在这里做错了吗？

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

推荐答案

正如您在评论中写的那样，问题是您总是返回 supports（）方法中，> false 。但是，您应该检查身份验证，而不是总是返回 true ：

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));
    }

    // ...
}
