spring boot oauth2 获取到access_token之后访问资源返回Cannot convert access token to JSON

已经获取到access_token，携带token访问资源时返回Cannot convert access token to JSON

这是什么问题。。。有没有人碰到过，后台也没提示报错之类的

重新生成RSA加密公钥私钥就好了~

参考解决方案：
1、在网关下面建一个类，用于拦截验证token是否过期或者非法
package com.immo.ymhis.gateway.exception;

import com.fasterxml.jackson.databind.ObjectMapper;
import org.springframework.http.MediaType;
import org.springframework.security.core.AuthenticationException;
import org.springframework.security.web.AuthenticationEntryPoint;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.HashMap;
import java.util.Map;

  public class AuthExceptionEntryPoint implements AuthenticationEntryPoint {

  @Override
  public void commence(HttpServletRequest request, HttpServletResponse response, AuthenticationException authException) throws ServletException {

    Map map = new HashMap();
    map.put("code", "401");
    map.put("message", "token非法");
    response.setContentType(MediaType.APPLICATION_JSON_VALUE);
    response.setStatus(HttpServletResponse.SC_UNAUTHORIZED);
    try {
        ObjectMapper mapper = new ObjectMapper();
        mapper.writeValue(response.getOutputStream(), map);
    } catch (Exception e) {
        throw new ServletException();
    }
  

  }
  }
  2、然后在配置类上加上这个异常

package com.immo.ymhis.gateway.config;

import com.immo.ymhis.gateway.exception.AuthExceptionEntryPoint;
import com.immo.ymhis.oauth2.common.config.DefaultResourceServerConf;
import org.springframework.context.annotation.Configuration;
import org.springframework.security.oauth2.config.annotation.web.configuration.EnableResourceServer;
import org.springframework.security.oauth2.config.annotation.web.configurers.ResourceServerSecurityConfigurer;

@Configuration
@EnableResourceServer
public class ResourceServerConfiguration extends DefaultResourceServerConf {

@Override
public void configure(ResourceServerSecurityConfigurer resources) {
    resources.resourceId("ymhis");
    resources.authenticationEntryPoint(new AuthExceptionEntryPoint());
}

}

3、效果

是设置.sercet() 这里吗？
