SIwave仿真手册——软件基础（一）最近在学习SIWAVE，在这里将自己的笔记整理一下，做一个专题。希望对大家有帮助，这个会持续更新的。仅限于软件操作学习，不涉及信号完整性的讨论。阅读详情

远程 rpc 调用成功，走本地 controller，注入的对象显示注入成功，但是调用方法就报错的问题。

请求失败代码：这个走的自己服务内的，userService 不是null，但是调用方法就报错



@RestController

@RequestMapping("/userService")

public class UserServiceController {



    @Autowired

    private UserService userService;



    @RequestMapping("/getAllUser")

    public List<UmsMember> getAllUser(){

        System.out.println(userService);

        List<UmsMember> umsMembers = userService.getAllUser();

        return umsMembers;

    }

}

请求成功代码：



@RestController

public class UserController {



    @Reference

    UserService userService;



    @RequestMapping("getAllUser")

    public List<UmsMember> getAllUser(){



        List<UmsMember> umsMembers = userService.getAllUser();

        return umsMembers;

    }

}

报错：

你这个代码 usrService 是想引用远程服务的？

我 dubbo 改造 spring cloud 的，把 @refrence 调用改成 feign 调用出的问题。

还以为你是本地服务调用本地service，调不通

就是本地掉本地的调不通，rpc 是通的，我那个打错字了，@Resource，指定了 bean 才注入成功的。

你这是属于没有找到mapper文件

拿麻烦看下问题在哪呢配置文件：


# mybtais 配置
mybatis.mapper-locations=classpath:mapper/*Mapper.xml
mybatis.configuration.map-underscore-to-camel-case=true

配置文件路径：

配置文件：mapper，实体类路径肯定是对的
