Spring Boot Oauth2扩展DefaultTokenServices

答案。缺少在configure方法中添加tokenServices（）

@Override    public void configure(AuthorizationServerEndpointsConfigurer endpoints) throws Exception {        final TokenEnhancerChain tokenEnhancerChain = new TokenEnhancerChain();        tokenEnhancerChain.setTokenEnhancers(Arrays.asList(tokenEnhancer()));        endpoints.tokenStore(tokenStore()).tokenServices(tokenServices()).tokenEnhancer(tokenEnhancerChain)     .authenticationManager(authenticationManager);    }
