Could not extract response: no suitable HttpMessageConverter found for ..content type [text/html...]

无法提取响应:没有找到适合响应类型的HttpMessage转换器

RestTemplate 采用的是 MappingJackson2HttpMessageConverter转换器，默认处理json类型的数据

双击 shift 键搜索：JacksonHttpMessageConvertersConfiguration，进入该类中

需要注意的是这个转换工具类实现的前提是，自己没有定义该工具类，如果自己定义了的话，会优先使用自己定义的覆盖系统自带的
