- Expert guidance for migrating Java projects from Spring Boot / Spring Cloud to the Solon framework. Provides comprehensive annotation mapping, dependency replacement, architecture differences, and step-by-step migration strategies for each layer (IoC, Web, Data, Cloud, Testing).
Spring to Solon Migration Skill
Provide expert guidance for migrating Java projects from Spring Boot / Spring Cloud to the Solon framework. Solon is an independent Java enterprise framework (NOT based on Spring) that offers similar developer experience but with different annotations, architecture, and ecosystem.
Official comparison: https://solon.noear.org/article/compare-springboot Official cloud comparison: https://solon.noear.org/article/compare-springcloud Solon website: https://solon.noear.org Current version: 3.10.x
Critical Migration Rules
- Solon is NOT Spring. Never mix Spring annotations with Solon annotations. Replace ALL Spring imports.
- No Spring dependencies. Remove all
spring-boot-starter-*, spring-* artifacts. Solon uses org.noear group ID. - Configuration file is
app.yml (or app.properties), NOT application.yml. - Entry point is
Solon.start(App.class, args), NOT SpringApplication.run(). - Parent POM is
solon-parent with groupId=org.noear. - Package scan uses
@Import on main class, NOT @ComponentScan. - No setter injection. Solon only supports field injection and constructor injection.
- All examples target Solon 3.10.x unless specified otherwise.
- 中文支持. When the user communicates in Chinese, all responses and code comments must be in Chinese.

Quick Migration Checklist
Step 1: POM 改造
- Replace
spring-boot-starter-parent → solon-parent - Replace Spring starters → Solon plugins
- Add
solon-maven-plugin - See:
references/dependency_mapping.md
Step 2: 配置文件
- Rename
application.yml → app.yml - Adjust configuration key names
- See:
references/config_system_migration.md
Step 3: 启动类
- Replace
@SpringBootApplication → @SolonMain - Replace
SpringApplication.run() → Solon.start() - See:
references/annotation_mapping.md
Step 4: 注解替换
- Replace all Spring annotations with Solon equivalents
- See:
references/annotation_mapping.md
Step 5: Web 层改造
- Replace
@RestController → @Controller - Replace
@RequestMapping → @Mapping - Handle
HttpServletRequest/Response → Context - See:
references/web_controller_migration.md
Step 6: 数据层改造
- Replace Spring transaction/cache annotations
- See:
references/datasource_orm_migration.md, references/transaction_cache_migration.md
Step 7: 微服务改造 (如适用)
- Replace Spring Cloud components with Solon Cloud equivalents
- See:
references/cloud_discovery_config_migration.md
Step 8: 测试改造
- Replace
@SpringBootTest → @SolonTest - See:
references/test_basics_migration.md
