第一章  Unsatisfied dependency expressed through field 'feignXxService'

初始代码：

ModelMap<Something> getSomething(String testA, String testB);

报错信息：

Error creating bean with name 'xxServiceImpl': Unsatisfied dependency expressed through field 'feignXxService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'com.test.test.xx.FeignXxService': FactoryBean threw exception on object creation; nested exception is java.lang.IllegalStateException: Method getSomething not annotated with HTTP method type (ex. GET, POST)

案情分析：

这是两个服务间的调用，服务A调用了服务B的getSomething方法，但是服务B并没有设置可远程调用。

改代码后：

@PostMapping(value = "/test/getSomething")
ModelMap<Something> getSomething(String testA, String testB);

第二章  Method has too many Body parameters

报错信息：

Method has too many Body parameters: public abstract org.springframework.ui.ModelMap com.test.test.xx.FeignXxService.getSomething(java.lang.String,java.lang.String)

案情分析：

服务B中没有指明访问的方式，而它默认是RequestBody，导致无法识别参数，报了错。

最终代码：

@PostMapping(value = "/test/getSomething")
ModelMap<Something> getSomething(@RequestParam(value = "testA") String testA,
                                 @RequestParam(value = "testB") String testB);
