3个回答

@RequestMapping("/admin-service-api")
public interface DevicePrisionerService {

@RequestMapping(value = "/getUser", method = RequestMethod.GET)
String getUser();

}
你的服务端路径是/admin-service-api/getUser,feign连接路径是/getUser当然404了,另外服务端应该是@controller注解驱动在类中对外提供接口,而不是和feign一样创建inteface,不应该这么写

你的feignClient调用的时的请求路径不对,这个路径和你直接访问你的服务地址的路径是一样的,你直接在浏览器中输入: ip:port+/getUser 同样会报404的。
修改为:@RequestMapping(value = "/admin-service-api/getUser", method = RequestMethod.GET);
还有如楼上说的,你的服务端代码有问题应该改改。

@FeignClient(name = "admin-service-api") 只是会去找到相应的服务,对应你的配置:

spring:
  application:
    name: admin-service-api

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 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789530_208977.png) ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789552_561331.png) ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789566_505603.png) 然后服务端的一个登录方法 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789576_928948.png) 客户端用Feign调用 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789587_486238.png) 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。 ![图片说明](https://img-ask.csdn.net/upload/201911/15/1573789601_125790.png) 麻烦各位大神能帮忙看看解决一下嘛,谢谢各位大神
Spring clouud eureka feign调用问题

openfeign里面配置httpclient出错。
因为现在需要使用get方式传递对象参数,所以尝试在openfeign里面配置httpclient。 配置代码如下: 在yml文件里面增加了配置信息 ``` feign: httpclient: enabled: true ``` 在pom.xml文件中引入的依赖: ``` <dependency> <groupId>org.apache.httpcomponents</groupId> <artifactId>httpclient</artifactId> <version>4.5.3</version> </dependency> <!-- 使用Apache HttpClient替换Feign原生httpclient --> <dependency> <groupId>com.netflix.feign</groupId> <artifactId>feign-httpclient</artifactId> <version>8.16.1</version> </dependency> ``` 配置好以后尝试使用get方式传递对象参数。 服务提供端代码: ``` @GetMapping(value = "testAddRole1",consumes = "application/json") public JsonResult addTest1(@RequestBody Role role){ roleService.addRole(role); return JsonResult.getInstant(ReturnCodeEnum.SUCCESS); } ``` 服务调用接口为: ``` @GetMapping(value = "/testAddRole1",consumes = "application/json") JsonResult testAddRole1(@RequestBody Role role); ``` 现在在尝试调用接口后发现服务提供方可以接受到参数并且能够写到数据库中,但是在服务调用方拿不到正确的返回值并且会报错,错误如下: ``` Caused by: java.lang.NoSuchMethodError: feign.Response.create(ILjava/lang/String;Ljava/util/Map;Lfeign/Response$Body;)Lfeign/Response; ``` 查看源码得知,openfeign在接受返回值时调用的不是httpclient的feign-core包的代码而是调用的本身的feign-core的代码,而本身的feign-core包中的Response类没有create方法。 得知原因后我将httpclient的依赖在pom文件中的位置上移,使openfeign优先调用httpclient的feign-core包的代码,结果在启动项目时就报错,报错信息为: ``` org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'test1Controller' defined in file [D:\workspace\basic\openfeign\target\classes\cn\cloudscope\openfeignTest\Test1\controller\Test1Controller.class]: Unsatisfied dependency expressed through constructor parameter 0; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'cn.cloudscope.openfeignTest.Test1.service.Test1Service': FactoryBean threw exception on object creation; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'feignRetryer' defined in org.springframework.cloud.openfeign.FeignClientsConfiguration: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [feign.Retryer]: Factory method 'feignRetryer' threw exception; nested exception is java.lang.NoSuchFieldError: NEVER_RETRY ``` 查看原因得知是两个feign-core包中的Retryer接口不一致导致的,求来个大神帮忙解决一下,或者怎么调整jar包的版本去解决这个问题。openfeign的feign-core版本为10.1.0 httpclient的版本为8.16.1
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(); } } ```
springboot2.2.0项目无法使用@EnableFeignClients已添加starter-openfeign和openfeign-core

阿里大鱼的短信问题!【进来表达一下意见,有价值就有积分!】
最近做的小程序里面,使用的是阿里大于的短信服务。 目前的问题是这样的:以前项目里的阿里大于短信服务是可以使用的,但是目前是余额不足的状态,所以又重新开了一个阿里大于的,有了新的secret和那个keyid,短信模板也换了一下。 这个时候我就改了项目中的三个地方,就是,secret,keyid,还有短信模板id,其他地方哪里都没动。 按说应该就可以用了。但是一直报错,好几天了折磨的我欲仙欲死。。。我用main函数,然后测试对应的secret,keyid,还有短信模板id, 是可以收到短信的!可以收到短信的!可以收到短信的! 但是放到项目里面,就一直报错,错误信息如下 第一次我修改后这样的错误: "Internal Server Error" exception : "java.lang.RuntimeException" message : "com.netflix.client.ClientException: Load balancer does not have available server for client: message-service" path : "/info/sendVerify" 第二次我修改后这样的错误: uid:435398420119687168 userMobile:13677778888 error : "Internal Server Error" exception : "feign.RetryableException" message : "Read timed out executing POST http://message-service/message/sendVerify?mobile=13677778888" path : "/info/sendVerify" status : 500 timestamp : 1544414058405 初步判定是项目的问题。。。但不知道是什么错误,好像跟springcloud里面的一些组件或者微服务之间的调用有些关系!请求大神指点!

volatile 与 synchronize 详解
Java支持多个线程同时访问一个对象或者对象的成员变量,由于每个线程可以拥有这个变量的拷贝(虽然对象以及成员变量分配的内存是在共享内存中的,但是每个执行的线程还是可以拥有一份拷贝,这样做的目的是加速程序的执行,这是现代多核处理器的一个显著特性),所以程序在执行过程中,一个线程看到的变量并不一定是最新的。 volatile 关键字volatile可以用来修饰字段(成员变量),就是告知程序任何对该变量...
Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员接私活怎样防止做完了不给钱?
