Is Spring Boot + Oauth2 ClientDetailsService empty all the time how to return a responsibility?

Token information Token is returned to be generated by Oauth2 after loginning found. But cannot make Token ClientDetailsService target all the time after test and verify is successful,be empty all the time do not know what returns a responsibility. Who has been encountered? Seek solution.

SecurityConfig.java configuration

@Override
	protected void configure(HttpSecurity http) throws Exception {
		// @formatter:off
		http.headers()
			.frameOptions()
			.disable();

		http.authorizeRequests()
			.antMatchers(\"/actuator/**\",
				\"/oauth/removeToken\",
				\"/oauth/delToken/*\",
				\"/oauth/listToken\",
				\"/mobile/**\").permitAll()
			.anyRequest()
			.authenticated();

		http.exceptionHandling()
			.accessDeniedHandler(new DreamAccessDeniedHandler(\"/accessDenied\"));

		http.formLogin()
			.loginPage(\"/login\")
//			.loginProcessingUrl(\"/session\")
			.loginProcessingUrl(\"/auth/oauth/token\")
			.failureHandler(authFailureEvenHandler)
			.successHandler(authSuccessEvenHandler)
			.authenticationDetailsSource(authDetailsSource)
			.permitAll();


		http.rememberMe()
			.tokenRepository(rememberMeTokenRepository())
			.userDetailsService(userDetailsService)
			.tokenValiditySeconds(30 * 24 * 60);

		http.logout()
			.logoutRequestMatcher(new AntPathRequestMatcher(\"/logout\"))
			.logoutSuccessUrl(\"/\")
			.deleteCookies(\"JSESSIONID\", \"remember-me\");

		http.csrf()
			.ignoringAntMatchers(\"/druid/**\", \"/ueditor\")
			.csrfTokenRepository(new CookieCsrfTokenRepository())
			.disable();
		// @formatter:on
	}

Is Debug of code of DreamAuthSuccessEvenHandler.java AuthSuccessEvenHandler specific implementation prints content to be nodded for empty problem in System.out.println(\” ClientDetailsService \”+clientDetailsService); why be all the time empty?
