springcloud使用feign实现服务间条用，参数数据太大，无法调用成功解决方法

公司项目做一个关于程序报错，实现给管理发送邮件提醒时使用springcloud的feign调用接口时总是走断路器

经过分析得出，调用接口时传递的参数过大，无法调用成功，解决方法如下：

1：引入springcloud关于feign依赖

<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form</artifactId>
<version>3.0.3</version>
</dependency>
<dependency>
<groupId>io.github.openfeign.form</groupId>
<artifactId>feign-form-spring</artifactId>
<version>3.0.3</version>
</dependency>

2：编写配置项

@Configuration
public class CoreFeignConfiguration {

@Autowired
private ObjectFactory<HttpMessageConverters> messageConverters;

@Bean
@Primary
@Scope(SCOPE_PROTOTYPE)
Encoder feignFormEncoder() {
return new SpringFormEncoder(new SpringEncoder(this.messageConverters));
}

@Bean
public Logger.Level logger() {
return Logger.Level.FULL;
}
}

3：启动类上添加注解

@EnableTransactionManagement

4：接口调用使用注解

@FeignClient(value = "sendemail", fallback = SendEmailHystrix.class,
configuration = CoreFeignConfiguration.class)
public interface SendEmail {

@RequestMapping(method = RequestMethod.POST, value = "sendemail/commonMail"
,consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
Object sendEmail(@RequestParam("addTo") String addTo,
@RequestParam("setSubject") String setSubject,
@PathVariable("details") String details);
}
