我是前后端分离的工程，需要搭建一个资源服务器，基于JWT的，但每次启动就会报Factory method 'jwtTokenEnhancer' threw exception; nested exception is org.springframework.web.client.RestClientException: Could not extract response: no suitable HttpMessageConverter found for response type [interface java.util.Map] and content type [text/html;charset=UTF-8]，这个是资源服务器代码

@Configuration
@EnableResourceServer
public class SsoResourceServerConfig extends ResourceServerConfigurerAdapter {
    @Override
    public void configure(HttpSecurity http) throws Exception {
        http.sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                .antMatchers(HttpMethod.GET, "/api/**").access("#oauth2.hasScope('read')")
                .antMatchers(HttpMethod.POST, "/api/**").access("#oauth2.hasScope('write')");
    }
    @Override
    public void configure(ResourceServerSecurityConfigurer resources){
        resources.tokenServices(tokenServices());
        resources.tokenStore(tokenStore());
    }

    @Bean
    public JwtAccessTokenConverter accessTokenConverter() {
        JwtAccessTokenConverter converter = new JwtAccessTokenConverter();
        converter.setSigningKey("imooc");
        return converter;
    }

    @Bean
    public TokenStore tokenStore() {
        return new JwtTokenStore(accessTokenConverter());
    }

    @Bean
    @Primary
    public DefaultTokenServices tokenServices() {
        DefaultTokenServices defaultTokenServices = new DefaultTokenServices();
        defaultTokenServices.setTokenStore(tokenStore());
        return defaultTokenServices;
    }

这个是资源服务器启动类

@SpringBootApplication
@EnableOAuth2Sso
@RestController
public class DemoApplication {
    @RequestMapping("/")
    public String hello() {
        return "hello";
    }
    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

我们项目用的是springboot2.0
这个是POM的有关安全框架的配置
