Java Rest 模板抛出 java.lang.IllegalArgumentException : Comparison method violates its general contract

转载作者：行者123 更新时间：2023-12-04 12:53:26

我没有使用任何 比较器/排序 在我的 Java 代码中，它仍然抛出“java.lang.IllegalArgumentException:比较方法违反了它的一般契约!”异常(exception)。
下面是在调试时在 restTemplate.exchange 行上抛出异常的一段代码。
当我将 spring-boot-starter-parent 的版本从 2.3.9 更改为 2.5.3 时开始出现此异常
我应该如何解决这个问题？

import org.springframework.web.client.RestTemplate;
Function call : AzureCredentials oStoreCreds = azureAutoConfiguration.getObjectStoreCreds(mop, new RestTemplate());

    @Bean
    @Profile("cf-azure")
    @Scope(value = WebApplicationContext.SCOPE_REQUEST, proxyMode = ScopedProxyMode.TARGET_CLASS)
    public AzureCredentials getObjectStoreCreds(ManagedObjectStoreProperties mosp, RestTemplate restTemplate) {
    try {
            String managed_instance_url = mosp.getGet_managed_instance_url().replace("{tenant_id}", tenantId);
            HttpHeaders headers = new HttpHeaders();
            headers.setBasicAuth(mosp.getUser(), mosp.getPassword());
            HttpEntity<?> entity = new HttpEntity<>(null, headers);
            ResponseEntity<ManagedObjectStoreAzureClientResponse> response = restTemplate.exchange(managed_instance_url, HttpMethod.GET, entity, ManagedObjectStoreAzureClientResponse.class);
            azureCredentials = response.getBody().getCredentials();
        } catch (RestClientException exception) {
            LoggerHelper.logError(LoggerHelper.getLogger(this.getClass()), "Fetching managed object store credentials failed.");
        }catch (Exception e){
            LoggerHelper.logError(LoggerHelper.getLogger(this.getClass()), "Generic Exception - Fetching managed object store credentials failed.");
        }
   return azureCredentials;
    }

最佳答案

堆栈跟踪表明，出于某种原因，MediaType.java 的 Comparator 方法上课不行。正如您所指出的，这似乎在本地有效，但在云中无效，我建议您比较运行时。
查看 AbstractMessageConverterMethodProcessor.java 的源代码当无法找到响应的内容类型时，将调用排序方法。也许你可以通过设置 accept 来强制一个内容类型请求中的 header 。假设您期待 JSON 响应:headers.setAccept(List.of(MediaType.APPLICATION_JSON));不确定这是否可以解决它，因为我无法首先重现该问题。
