feign客户端get请求，服务端抛出Method Not Allowed: Request method ‘POST‘ not supported

在feign调用时，客户端get请求，服务端接受也是get请求，但是执行请求报错
Method Not Allowed: Request method ‘POST’ not supported

1.feign客户端

@GetMapping(“/list”)
Result<?> queryPageList(SystemAccountBookDetail systemAccountBookDetail,
@RequestParam(name = “pageNo”, defaultValue = “1”) Integer pageNo,
@RequestParam(name = “pageSize”, defaultValue = “10”) Integer pageSize) {

return sysAccountBookDetailService.queryPageList(systemAccountBookDetail,pageNo,pageSize);

}

2.feign服务端

@Component
@FeignClient(value = FeignConstant.OCP_CLOUD_SYSTEM, fallbackFactory = AccountAPIFallbackFactory.class)
public interface AccountApi {
    
    

    @GetMapping(value = "/account/accountBookDetail/list")
    Result<?> accountBookDetailPageList(@RequestParam(name = "pageNo", defaultValue = "1") Integer pageNo,
                                        @RequestParam(name = "pageSize", defaultValue = "10") Integer pageSize,
                                        SystemAccountBookDetail systemAccountBookDetail);

}

原因：因为使用了SystemAccountBookDetail 对象，而在feign调用中无法识别是否为get/post 请求，因此强转成了post请求，导致在服务端报错Method Not Allowed: Request method ‘POST’ not supported

解决：在feign服务端api中，加上注解@SpringQueryMap 即可解决，注解的作用是将实体转成表单数据

如下：

@Component
@FeignClient(value = FeignConstant.OCP_CLOUD_SYSTEM, fallbackFactory = AccountAPIFallbackFactory.class)
public interface AccountApi {
    
    

    @GetMapping(value = "/account/accountBookDetail/list")
    Result<?> accountBookDetailPageList(@RequestParam(name = "pageNo", defaultValue = "1") Integer pageNo,
                                        @RequestParam(name = "pageSize", defaultValue = "10") Integer pageSize,
                                        SystemAccountBookDetail systemAccountBookDetail);

}
