禁用指定的自动配置

 springboot禁用特定的自动配置类  

@RestController
public class XXXController

@Resource(name = "xxxService")
private XxxService   xxxService;
  

@RequestMapping(value = "xxxService", method = { RequestMethod.POST, RequestMethod.GET })
public Object xxxService(HttpServletRequest request) {
    
   
   
@Transactional
public X xxx(Map params)
