Anonymous access of method from Jersey webservice which is secured with spring security and oAuth2

Question

I have one Jersey Rest web service which handles person account CRUD.
I have spring security+ oAuth2 to secure this api , what i am not able to configure is , i wanted to make anonymous of Account create method. i tried to configure intercept url but it does not work method level. so do i need to write separate class for this purpose or i can achieve without it.

Sample class code

public class AccountResource{

createAccount() --- I want this method to be accessed by Anonymous uers so they can create account without generating tokens.
updateAccount() --
findAccount() --
deleteAccont()--

} 

Config code which makes secure all calls starting '/services/rest/**'

<http pattern="/services/rest/**" create-session="never"
        entry-point-ref="oauthAuthenticationEntryPoint"
        xmlns="http://www.springframework.org/schema/security">
        <anonymous enabled="false" />
        <intercept-url pattern="/services/rest/**" method="GET" access="ROLE_USER" />
        <intercept-url pattern="/services/rest/**" method="POST" access="ROLE_USER" />
        <intercept-url pattern="/services/rest/**" method="PUT" access="ROLE_USER" />
        <intercept-url pattern="/services/rest/**" method="DELETE" access="ROLE_USER" />
        <custom-filter ref="resourceServerFilter" before="PRE_AUTH_FILTER" />
        <http-basic entry-point-ref="oauthAuthenticationEntryPoint" />
        <access-denied-handler ref="oauthAccessDeniedHandler" />
    </http>

Answer 1

How about changing the configuration for POST requests in your security config to:

<intercept-url pattern="/services/rest/**" access="permitAll" method="POST" />
