解决Spring Security OAuth在访问/oauth/token时候报401 authentication is required

/oauth/token

• 这个如果配置支持allowFormAuthenticationForClients的，且url中有client_id和client_secret的会走ClientCredentialsTokenEndpointFilter来保护
• 如果没有支持allowFormAuthenticationForClients或者有支持但是url中没有client_id和client_secret的，走basic认证保护

 @Override
    public void configure(AuthorizationServerSecurityConfigurer oauthServer) throws Exception {
        oauthServer
                .tokenKeyAccess("permitAll()")
                .checkTokenAccess("permitAll()")
                .allowFormAuthenticationForClients();
    //	oauthServer.allowFormAuthenticationForClients();
   }
