在我正在审查的基于 Spring Framework 3.2 的应用程序中，我注意到 Spring 的 PluggableSchemaResolver 在运行时生成一个映射，其中包括许多旧的 Spring 架构。为了清楚起见缩写:
w.sf.o/s/ means www.springframwork.org/schemas/
和
o/sf/ means org.springframework

仅使用 Spring 3.2 定义创建我自己的 spring.schemas 和 spring.handlers 文件不会减少此映射集。
Spring 在运行时拥有遗留映射是正常的吗？
最佳答案
是的；这是正常的。每个Spring JAR，例如spring-tx-3.2.14.RELEASE.jar，都包含一个META-INF/spring.schemas，其中包含所有支持的Spring版本的映射；在 spring-tx-3.2.jar 中，spring.schemas 包含:
http\://www.springframework.org/schema/tx/spring-tx-2.0.xsd=org/springframework/transaction/config/spring-tx-2.0.xsd
http\://www.springframework.org/schema/tx/spring-tx-2.5.xsd=org/springframework/transaction/config/spring-tx-2.5.xsd
http\://www.springframework.org/schema/tx/spring-tx-3.0.xsd=org/springframework/transaction/config/spring-tx-3.0.xsd
http\://www.springframework.org/schema/tx/spring-tx-3.1.xsd=org/springframework/transaction/config/spring-tx-3.1.xsd
http\://www.springframework.org/schema/tx/spring-tx-3.2.xsd=org/springframework/transaction/config/spring-tx-3.2.xsd
http\://www.springframework.org/schema/tx/spring-tx.xsd=org/springframework/transaction/config/spring-tx-3.2.xsd
只是在花时间思考并随后查看源代码和生成的 JAR 以找到答案后分享。
