使用fegin调用远端接口是发生错误：creating bean with name ‘xxx’: Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: name is required.

具体报错如下：

  1. org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'wechatControllerImpl': Unsatisfied dependency expressed through field 'touTiaoPushServiceImpl'; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'touTiaoPushServiceImpl': Unsatisfied dependency expressed through field 'touTiaoService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.bowen.service.service.toutiao.TouTiaoService': Unexpected exception during bean creation; nested exception is java.lang.IllegalArgumentException: name is required.

解决方案

主要原因是,在fegin接口中定义的接口路径多了个？导致系统识别为不存在name

  1.   @PostMapping(value = "/article/new?")
  2.     String sendMircoMsg(@RequestBody Map<String, Object> msgContent);

正确写法,去掉问号。

  1.   @PostMapping(value = "/article/new")
  2.     String sendMircoMsg(@RequestBody Map<String, Object> msgContent);
