简介： 这篇文章讲述了作者在微服务项目开发中遇到的一个具体问题：使用Feign进行远程服务调用时出现了`status 500`错误。文章详细描述了排查过程，包括检查Feign配置和被调用服务的日志信息，最终确定问题是由于Lombok插件的`@Data`注解导致。作者通过将`@Data`注解注释掉并手动生成get、set方法解决了问题，并提供了成功调用远程服务后的截图。

排查思路

由于调用的是远程服务，是不是远程调用远程服务的fegin没有配置好，经过排查不是

查看被调用方方的日志信息，这里说插入的sql语句有问题，使用的是mybatis-plus进行的基本操作。那应该就是实体类的问题、这两天一只遇到lombok导致项目启动失败，读取不到类之类的问题，解决方法也是手动生成get、set方法。去修改lombok的版本和IDEA的配置是麻烦。实体类中使用的是Lombok插件，使用的@Data注解，将@Data注解注释掉，然后手动生成get、set方法。成功解决

解决方法

在确定远程调用服务是正常的情况下，将由Lombok改为手动生成get/set方法。这里调用服务传递的参数是一个实体类，实体类中讲由@Data改为手动生成get、set方法。

成功
