无法在Spring云中调用RestEndpoint

Question

下面是链接中的Netflix Eureka的Spring云服务发现教程：https://howtodoinjava.com/spring/spring-cloud/spring-cloud-service-discovery-netflix-eureka/.

在源代码中，我简单地使用了sping-boot-starter-父version1.5.13。BUILD-SNAPSHOT而不是1.5.4。RELEASE，没有其他更改。

我试着打电话给spring eureka客户端学生服务，使用http://localhost:8098/getStudentDetailsForSchool/abcschool，但我没有看到生成任何日志，看起来没有呼叫要服务。

    public static void main(String[] args) {

Answer 1

请在包com中移动SpringEurekaClientStudentServiceApplication。howtodoitinjava而不是com。howtodoitinjava。示例

>

如果您的其他软件包层次结构位于带有@SpringBootApplication注释的主应用程序下方，则隐式组件扫描将覆盖您。

如果其他包中有bean/组件不是主包的子包，则应手动将它们添加为
@ComponentScan

在您的情况下，您可以编写如下内容（如果您不想移动主类）：

 @ComponentScan({“com.howtodoitinjava”})
