The spring-cloud-alibaba-dependencies BOM (Bill of Materials) simplifies managing compatible versions of Spring Cloud Alibaba dependencies in your project. Here's how you can use it effectively:
1. What is spring-cloud-alibaba-dependencies?
- It is a dependency management BOM provided by Spring Cloud Alibaba to ensure compatibility between its components and Spring Boot/Spring Cloud versions.
- It defines specific versions for Spring Cloud Alibaba modules like
nacos-config,nacos-discovery, and others.
2. How to Use spring-cloud-alibaba-dependencies?
Maven Configuration
Add it to your <dependencyManagement> section for managing dependencies:
<dependencyManagement> <dependencies> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-alibaba-dependencies</artifactId> <version>2021.0.1.0</version> <!-- Use the appropriate version --> <type>pom</type> <scope>import</scope> </dependency> </dependencies> </dependencyManagement> <dependencies> <dependency> <groupId>com.alibaba.cloud</groupId> <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId> </dependency> </dependencies>
Gradle Configuration
In Gradle, you can use the BOM like this:
dependencies { implementation platform('com.alibaba.cloud:spring-cloud-alibaba-dependencies:2021.0.1.0') implementation 'com.alibaba.cloud:spring-cloud-starter-alibaba-nacos-config' }
3. Choosing the Right Version
The version of spring-cloud-alibaba-dependencies you select depends on the Spring Boot and Spring Cloud versions you're using. Here's a compatibility guide:
| Spring Cloud Alibaba Version | Spring Boot Version | Spring Cloud Version |
|---|---|---|
| 2.2.5.RELEASE | 2.3.x | Hoxton.SR8 |
| 2021.0.1.0 | 2.5.x | 2020.0.x |
