org.apache.camel.FailedToCreateRouteException：创建路由失败：因为名称为静态方法：methodA() 在类中找不到：

Question

我正在使用 mockito 和 camelTestSupport 编写骆驼路线测试，但测试失败并出现以下错误：

Caused by: org.apache.camel.component.bean.MethodNotFoundException: 静态方法名称: methodA not found on class: .service.impl.ServiceImpl 在 org.apache.camel.component.bean.DefaultBeanProcessorFactory.createBeanProcessor

The method is present in service impl, and is defined as below:
 public Object methodA(@Headers Map headers, @Body String payload) {
        return new ResponseEntity<>(HttpStatus.BAD_REQUEST);
    }
