java - Spring oauth拦截rest api调用并从一个拦截器转发

Question

我已经配置了所有的 spring security 和 oauth token 获取等

但是我是否必须在每个 REST API 调用中从数据库验证用户？

这是我的示例 API:

@GET
@Path("/getUUID")
public Response getUUID(@Context HttpServletRequest request, final @Context SecurityContext securityContext) {
    //here do i have to do this in each api or there is one filter that can i write and pass this user object from that to api
    User loadUser = loadUserFromSecurityContext(securityContext);
}

protected User loadUserFromSecurityContext(SecurityContext securityContext) {

    OAuth2Authentication requestingUser = (OAuth2Authentication) (securityContext).getUserPrincipal();
    String principal = requestingUser.getUserAuthentication().getName();
    User user = null;
    user = new UserDAO().getUser(principal);

    return user;
}

您可以通过实现以下过滤器来拦截 api 调用:

public class AuthenticationTokenProcessingFilter extends GenericFilterBean {

AuthenticationManager authManager;

public AuthenticationTokenProcessingFilter(AuthenticationManager authManager) {
    this.authManager = authManager;
}

@Override
public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {        
    HttpServletRequest httpServletRequest = (HttpServletRequest)request;

    //access your token here and do what you wanna do with it
    String authToken = httpServletRequest.getHeader("AUTHORIZATION");

    // continue thru the filter chain
    chain.doFilter(request, response);
  }
}

在你的 spring-servlet.xml 中

<http pattern="/api/**" create-session="never" use-expressions="true"
      entry-point-ref="oauthAuthenticationEntryPoint" xmlns="http://www.springframework.org/schema/security">
    <anonymous enabled="false" />
    <intercept-url pattern="/api/**" />
    <custom-filter ref="resourceServerFilter" before="PRE_AUTH_FILTER" />
    <custom-filter ref="authenticationTokenProcessingFilter" before="FORM_LOGIN_FILTER"/>
    <access-denied-handler ref="oauthAccessDeniedHandler" />
</http>

<bean id="authenticationTokenProcessingFilter" class="com.yourpackage.AuthenticationTokenProcessingFilter">
    <constructor-arg ref="authenticationManager" />
</bean>
