+
+2. 构建 `SCA SNAPSHOT版本`(依赖[`io.opensergo:opensergo-java:0.0.1-SNAPSHOT`](https://github.com/opensergo/opensergo-java/packages/1332235))
+
+   ```bash
+   git clone https://github.com/robberphex/spring-cloud-alibaba.git
+   cd spring-cloud-alibaba
+   git checkout opensergo
+   mvn clean compile install -DskipTests
+   ```
+
+3. 编译此项目：
+
+   ```bash
+   git clone https://github.com/robberphex/example-opensergo-sca.git
+   cd example-opensergo-sca
+   mvn clean compile package -DskipTests
+   # 最终产物 ./target/opensergo-sc-demo-0.0.1-SNAPSHOT.jar
+   ```
+
+4. 运行此项目：
+
+   ```shell
+   env OPENSERGO_BOOTSTRAP_CONFIG='{"endpoint":"localhost:9090"}' \
