springmvc转springboot an authentication object was not found

No converter found for return value of type: class org.springframework.security.oauth2.common.DefaultOAuth2AccessToken

出现以上错误的原因是因为没有为SpringMVC引用所需的message converter包，引入如下两个包即可：


<dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-core</artifactId>
          <version>2.8.6</version>
      </dependency>
      <!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
      <dependency>
          <groupId>com.fasterxml.jackson.core</groupId>
          <artifactId>jackson-databind</artifactId>
          <version>2.8.6</version>
      </dependency>
