我使用的是Sping Boot 应用程序版本2.7.9。在从RestTemplateBuilder创建restTemplate时，我遇到以下异常：

The dependencies of some of the beans in the application context form a cycle:

???->???
|  srGroupController (field org.springframework.web.client.RestTemplate com.example.demo.SrGroupController.restTemplate)
???<-???


@RestController
@RequestMapping("/api/srgrp/")
public class SrGroupController {    
        
    @Autowired
    @Qualifier("jiraRT")
    RestTemplate restTemplate;  
    
    @Bean(name = "jiraRT")
    public RestTemplate restTemplate(RestTemplateBuilder builder) {
        return builder.basicAuthentication("myuser", "paswword").build();
    }
    
    
    @RequestMapping (value = "ping", method = RequestMethod.GET,produces = MediaType.APPLICATION_JSON_VALUE)
    public String ping() {  
        
        return "ping works!";       
    }   
}
