问题解决

根据报错发现根源在这个类：agentServiceRepository
这个接口的源码如下：

public interface AgentServiceRepository
  extends JpaRepository<AgentService, String>
{
  AgentService findByIdAndOrgi(String paramString, String orgi);
  
  List<AgentService> findByUseridAndOrgiOrderByLogindateDesc(String paramString, String orgi);

  @Query(value = "SELECT * FROM uk_agentservice WHERE userid= ?1 AND orgi = ?2 ORDER BY logindate DESC LIMIT 1", nativeQuery = true)
  Optional<AgentService> findOneByUseridAndOrgiOrderByLogindateDesc(String userid, String orgi);

  AgentService findFirstByUserid(String userid);

  Page<AgentService> findByOrgi(String orgi, Pageable paramPageable);
  
  Page<AgentService> findByOrgiAndSatisfaction(String orgi, boolean satisfaction, Pageable paramPageable);
  
  Page<AgentService> findByOrgiAndStatus(String orgi, String status, Pageable paramPageable);
  
  List<AgentService> findByAgentnoAndStatusAndOrgi(String agentno, String status, String orgi);
  
  int countByUseridAndOrgiAndStatus(String userid, String orgi, String status);
  
  List<AgentService> findByUseridAndOrgiAndStatus(String userid, String orgi, String status, Sort sort);
  
  Page<AgentService> findAll(Specification<AgentService> spec, Pageable pageable);  //分页按条件查询


}

第一个方法是根据id查询，springboot 2.X之后根据id查询的返回结果都必须是Optional封装的，修改为如下就好了：

Optional<AgentService> findByIdAndOrgi(String paramString, String orgi);
