sap-cloud-sdk - 启用S??pring Security后无法在本地启动应用程序(Fail to start application locally after ensbling Spring Security)

Question

I am trying to enable spring security to protect my backend services in SDK archetype project based on Spring according to the tutorial https://blogs.sap.com/2017/07/18/step-7-with-sap-s4hana-cloud-sdk-secure-your-application-on-sap-cloud-platform-cloudfoundry/ .

(我正在根据教程https://blogs.sap.com/2017/07/18/step-7-with-sap-s4hana-cloud尝试启用Spring安全性以保护基于Spring的SDK原型项目中的后端服务sdk将您的应用程序在汁液云平台平台cloudfoundry /上安全 。)

After I start the application locally, an error message shows up - "Environment variable VCAP_SERVICES not set".

(在本地启动应用程序后，出现错误消息-“未设置环境变量VCAP_SERVICES”。)

Below is the stack trace of this error.

(下面是此错误的堆栈跟踪。)

The steps to reproduce the issue：

(重现此问题的步骤：)

1. Create a fresh sdk archetype project based on Spring

   (基于Spring创建一个新的sdk原型项目)

2. Uncomment out all the code in SecurityConfig.java

   (取消注释SecurityConfig.java中的所有代码)

3. Import all the security libraries

   (导入所有安全库)

4. Start the application locally

   (在本地启动应用程序)

The application is running well on SCP Cloud Foundry.

(该应用程序在SCP Cloud Foundry上运行良好。)

I know the root cause is the application is going to read Environment variable VCAP_SERVICES when initializing bean in SecurityConfig.java.

(我知道根本原因是在SecurityConfig.java中初始化bean时，应用程序将读取环境变量VCAP_SERVICES。)

But it cannot find it in local environment.

(但是它无法在本地环境中找到它。)

Is there any workaround if I want to run application locally?

(如果我想在本地运行应用程序，是否有任何解决方法？)
