SpringCloud Feign调用返回结果封装后异常问题

我一个项目采用SpringCloud框架,服务端客户端采用Feign调用。
服务端返回结果封装了一个Result对象来进行包装

然后服务端的一个登录方法

客户端用Feign调用

但是测试的时候,无论服务端返回各种结果都是报错,报枚举类超出范围异常,Feign已拿到值,但是都是报那个Code的超出枚举类异常,但是枚举类是已经定义了。

麻烦各位大神能帮忙看看解决一下嘛,谢谢各位大神

1个回答

Result类中setCode方法,参数不要直接使用枚举类型,逻辑有点混乱,setCode就应该接收int类型,不然你序列化的时候将int直接序列化枚举类型就会报错

springcloud feign 找不到服务 value 和 url

springcloud feign 注解 RequestLine 相对于 RequestMapping有什么优势吗?
目前springcloud项目 对外暴露的接口上面url用@requestMapping注解的, 但是我觉得用RequestLine更合适 因为这是Feign的注解,对外暴露也是用Feign的,请问 如题,注解 RequestLine 相对于 RequestMapping有什么优势吗?
SpringCloud Feign 替换默认配置,不加 @Configuration怎么理解?
### SpringCloud Feign 替换默认配置,不加 @Configuration怎么理解? ### 在学习Feign的时候有看到替换默认配置要么把配置类创建到启动类外层目录,这样要加@Configuration注解,要么是放在同级或下级目录,此时不加@Configuration。 ### 但是实际实验结果表示,放在同级或下级目录,不加@Configuration,则会报错,或者不生效。 ### 那么该怎么理解官方文档的这段话呢? > FooConfiguration不需要使用@Configuration注释。但是,如果是,则请注意将其从任何@ComponentScan中排除,否则将包含此配置,因为它将成为feign.Decoder,feign.Encoder,feign.Contract等的默认来源,指定时。这可以通过将其放置在任何@ComponentScan或@SpringBootApplication的单独的不重叠的包中,或者可以在@ComponentScan中明确排除。 ### 相关代码 ``` java // 启动类在com.vvlin包下 package com.vvlin.config; ... // 这里注释掉之后,不会在控制台打印,说明方法未调用 // 不注释则正常 // @Configuration public class FeignUploadFileConfiguration { @Bean public Encoder feignFormEncoder() { System.err.println("FeignUploadFileConfiguration.feignFormEncoder()"); return new springFormEncoder(); } } ```

SpringCloud项目中用jmeter测试feign负载 异常率比直接访问client生产者还高
初入SpringCloud坑的小白 把SpringCloud负载均衡作为毕设课题研究 能不能有个大佬帮我分析一下问题 三台服务器 学生云 1核2G 带宽1M 五个项目 Eureka,fegin消费者,clientA,clientB,clientC三个生产者 **服务器1:Eureka,feign ,clinetA 服务器2:clientB 服务器3:clientC** 使用jmeter测试500线程/S 持续3秒 共计1500线程 访问feign和clientA **测试1访问feign**:异常率在33%左右 **测试2访问clientA**:异常率在28-33%左右 异常的基本上都是连接超时failed: Connection timed out: connect 在服务器1上抓包查看请求发现有的请求报了一些错 ``` 2019-05-12

有没有大神帮忙分析一下用feign负载之后异常率比直接访问client异常率还高的原因。。
spring微服务调用,没有注册中心也能用吗?
几个spring微服务的问题,请指教: 1、springboot开发用RestTemplate和feign方式,如果没有部署注册中心,也可以调用吧,也可以分布式部署微服务?那么很多场景下用户不需要对服务调用进行细粒度管控,是否可以不部署注册中心? 2、如果部署了注册中心如Eureka,是否所有controller都会被注册?注册中心会记录服务的调用情况包括日志等,那么正常从浏览器和APP发起的调用也会被记录吗? 3、服务提供者和消费者都要注册到注册中心,那么从浏览器和APP发起的调用应该没有注册消费者吧?这样注册中心的服务调用管理并不全面吧?是只包括微服务之间的调用吧?是否应只注册需要被其它微服务调用的controller而不是全部? 4、服务调用好像都是调用controller,能否调用其它微服务应用的service层?controller通常是为前端调用设计的,参数是DTO,而service的参数是DO|PO,在写业务时,可能更多使用后者。 5、用RestTemplate调用服务时,@LoadBalanced注解可实现负载均衡,如果没有部署注册中心,调用时直接写的服务方地址,怎么可能实现负载均衡呢?是否@LoadBalanced必须和注册中心一起用?没有注册中心的情况下如果一个微服务部署多个实例,我们是在nginx中配置集群的,调用地址就是集群的域名,即负载均衡是由nginx实现的,spring的负载均衡是由什么实现的?
求助大神帮忙看看,关于feign调用的一个问题,卡在那里直到超时

Feign在开启Hystrix后,feign.client超时时间设置有什么用?
1、Feign开启Hystrix 配置文件如下: ``` feign: hystrix: enabled: true ``` 2、配置feign客户端超时时间: ``` feign: client: config: default: connectTimeout: 8000 readTimeout: 10000 ``` 请求一个休眠6秒的接口,会超时。 3、当配置Hystrix超时时间后,能正常访问,配置如下: ``` hystrix: shareSecurityContext: true command: default: execution: isolation: thread: timeoutInMilliseconds: 8000 ``` 请问:feign.client的超时时间配置有什么用?
springboot分布式项目用cas做sso,服务间接口调用返回登录页
用springboot写了两个微服务,目前都在本地启动测试,cas server5.3已经部署到服务器上, 两个微服务设置好cas后启动,调用第一个服务接口,跳转到cas登陆,登陆成功后,第二个服务自己的接口也能够正常访问。 然后写服务间接口的调用,用的feign,在注释到cas后可以取到其他服务的接口返回值,但是加上cas后就返回登陆的html,而且这个html不能使用。但是不涉及到服务间调用的接口还是正常可以访问。不知道还需要配置什么,求大佬指教 ![图片说明](https://img-ask.csdn.net/upload/201910/14/1571030677_792935.png)
微服务间接口调用返回cas登陆的html

springcloud oauth2.0 jwt 前后端分离的几个问题
oauth2.0提供了一种客户端模式获取token的方式,A微服务就可以用feign通过这种模式请求B服务的相关接口。(zuul,eureka) 第一个问题: 是否有这样一种场景,前端调用A服务的某接口,而这个接口需要调用B服务的某接口,但是这个接口需要用户有一定角色权限才可调用,前端登录的用户是有这种角色权限的,但是由于A服务调用B服务是通过客户端模式生成的token和用户是没关系的,所以会因为没权限调用不了?A服务调用B服务是都通过客户端模式生成token去调用还是会判断前端是否传token,有的话把前端传过来的token继续传过去呢? 第二个问题: 而假设现在不是由前端调用,而是A服务有个定时器,需要调用B服务查询数据的一个接口,而B服务的这个接口是不应该让前端可以调用到。如果正常写接口的话,用户应该还是可以通过zuul到eureka调用到这个接口的吧?这时怎么限制这个不让前端进行调用?修改zuul匹配规则只能请求某路径开头的接口?还是别的怎么方式? 第三个问题: 我github上看了一个基于jwt的前后端分离的oauth2.0的单点登录项目,前端nodejs+vue,然后登录的时候是自定义实现的,用户名+密码+clientid+clientsecret获取token,然后后面可以用refreshtoken + clientid + clientsecret调用接口/oauth/token 续期token。而由于他这里是直接在js里面发起请求到zuul层,所以clientid和clientsecret是直接暴露在js里面的,然后上面说了有一种客户端模式获取token,就是只需要clientid+clientsecret就可以拿到token,只是不能refresh。这样的话把clientid和clientsecret直接写在js里面暴露出来靠谱吗? 而登录已经需要用户名密码了为什么还让传clientid和clientsecret。有什么意义吗?传clientid能理解,clientid有一个scope,但感觉好像没必要也要传clientsecret
