Feign中如何实现传实体Bean

本篇内容主要讲解“Feign中如何实现传实体Bean”，感兴趣的朋友不妨来看看。本文介绍的方法操作简单快捷，实用性强。下面就让小编来带大家学习“Feign中如何实现传实体Bean”吧!

Feign如何传实体Bean

需要加一个@RequestBody序列化对象

    /**
     * 新增
     */
    @PostMapping("saveOrder")
    @ResponseBody
    public void saveOrder(@RequestBody OrderBean orderBean) {
        userService.saveOrder(orderBean);
    }

接口接收请求也要加一个@RequestBody注解 

    /**
     * 新增
     * @param orderBean
     */
    @PostMapping("saveOrder")
    public void saveOrder(@RequestBody OrderBean orderBean);

Feign注入Bean为null,启动报错

主要是feign版本和swagger版本冲突，本项目spring cloud 版本为 Finchley.M8

swagger冲突版本

        <!-- swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.2.2</version>
        </dependency>

解决方案

        <!-- swagger2 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.5.0</version>
        </dependency>
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.5.0</version>
        </dependency>

feign Service案例

@FeignClient(name  = "service-weixin",fallback = OAuthServiceFallBack.class, configuration = FeignConfig.class)
public interface OAuthService {
     @RequestMapping(value = "/oauth/getOauth3AuthorizationUrl", method = RequestMethod.GET)
     ResultBean<String> getOauth3AuthorizationUrl(@RequestParam("url")String url);
}

controller注入

@RestController
@RequestMapping("/ticket")
public class TicketController {
    @Autowired
    private TicketService ticketService;
    @Autowired
    private OAuthService oAuthService;
    ...
