Question

我有data，business和web图层的不同Java项目。我在web层初始化Spring上下文，并且只在web层中包含所有Spring bean XML文件。

@Autowired功能仅适用于web层中的Spring bean（并不适用于其他两个项目中的Spring bean）。

我是否还需要在其他两个项目（data和business）中定义Spring bean XML配置？

Answer 1

我建议为每个项目使用不同的Spring XML配置文件（或更多，具体取决于您的需要）。例如，JPA存储库用于在data项目中声明，并在需要时导入;其他人一样。

查看Spring的import。

我认为您可以在每个项目中包含许多配置文件，并且可以使用（web路径/META-INF/*从<import resource="classpath:/META-INF/spring-context-data.xml" /> <import resource="classpath:/META-INF/spring-context-business.xml" />导入它们）：

Answer 2

这是我的错误......我在界面中使用了注释（比如@Repository，@ Service）而不是实现类。将它移到课堂后，它可以正常工作。

Spring @Autowired不使用跨多个项目的配置文件
