This project is a sample Spring Cloud application that implements a microservices architecture with services like product and order management, and an API gateway for service routing.

• Java JDK 1.8
• Maven
• MySQL Server
• Nacos Service Discovery
• Alibaba Sentinel
• Jmeter

Ensure Java and Maven are installed on your system and the JAVA_HOME environment variable is set.

1. Clone the repository to your local machine.
2. Create MySQL databases shop_product and shop_order.
3. Start the Nacos Service Discovery and Configuration server. 4.Start the Alibaba sentinel and Jemeter to pull Http request.

The project includes the following microservices:

• shop-product-api: The API definition for the product service.
• shop-product-server: Implementation of the product service.
• shop-order-api: The API definition for the order service.
• shop-order-server: Implementation of the order service.
• api-gateway: The gateway service that routes API requests to the appropriate microservice.\

Each service has its own application.yml or application.properties file in the src/main/resources directory where you can set up the datasource, server port, and other configurations.

• server.port: The port on which the service will run.
• spring.application.name: The name of the application in the service registry.
• spring.datasource: The datasource configuration.
• spring.jpa: The JPA/Hibernate configuration.
• spring.cloud.nacos.discovery.server-addr: The address of the Nacos server.

Each microservice can be started with the Spring Boot Maven plugin. Below are the commands to start each service:

cd api-gateway
mvn spring-boot:run

To start the shop-product-api, run the following command:

cd shop-product-api
mvn spring-boot:run

To start the shop-product-server, use this command:

cd shop-product-server
mvn spring-boot:run

Start the shop-order-api with:

cd shop-order-api
mvn spring-boot:run

To launch the shop-order-server, execute:

cd shop-order-server
mvn spring-boot:run

sh startup.sh -m standalone

startup.cmd -m standalone

Alibaba Sentinel provides a dashboard for monitoring and managing rules in a graphical interface.

To start the Sentinel dashboard, execute the following command in the directory where Sentinel is located

java -Dserver.port=8080 -jar sentinel-dashboard-1.8.0.jar

Apache JMeter is an open-source load testing tool. You can use it to test the performance and stability of your services under different load conditions.

• Download and install Apache JMeter.
• Open JMeter GUI by running the jmeter command in the bin directory of JMeter.
• Configure your test plan by adding Thread Groups, HTTP Request samplers, listeners, etc.

1. In JMeter, create a new Test Plan.
2. Add a Thread Group to define the number of users and ramp-up period.
3. Add an HTTP Request sampler to set up requests to your services.
4. Add a Listener (e.g., View Results in Table) to view the results.
5. Start the test by clicking the 'Start' button (green play icon).

To integrate JMeter with Sentinel, you need to:

1. Add the Sentinel dependency to your project's pom.xml.
2. Configure Sentinel resource rules in your application.
3. Run your JMeter tests and observe the results on the Sentinel dashboard.
