我正在努力从我的自定义库(通过gradle导入)自动装配bean。阅读了几个类似的主题后,我仍然找不到解决方案。
我有依赖于其他项目的Spring Boot项目(我的自定义库以及Components,Repositories等…)。这个库是一个Spring不可运行的jar,主要由域实体和存储库组成。它没有可运行的Application.class和任何属性…
当我启动应用程序时,我可以看到我的’CustomUserService’bean(来自库)正在尝试初始化,但是自动装配到其中的bean无法加载(接口UserRepository)…
错误:
com.myProject.customLibrary.configuration.CustomUserDetailsService中构造函数的参数0需要找不到类型为com.myProject.customLibrary.configuration.UserRepository的bean。
我什至尝试设置’Order’,以显式加载它(使用’scanBasePackageClasses’),使用包和标记类进行扫描,添加其他’EnableJPARepository’注释,但是没有任何效果…
代码示例(为简单起见,更改了程序包名称)
package runnableProject.application; import runnableProject.application.configuration.ServerConfigurationReference.class import com.myProject.customLibrary.SharedReference.class //@SpringBootApplication(scanBasePackages = {"com.myProject.customLibrary", "runnableProject.configuration"}) //@EnableJpaRepositories("com.myProject.customLibrary") @SpringBootApplication(scanBasePackageClasses = {SharedReference.class, ServerConfigurationReference.class}) public class MyApplication { public static void main(String[] args) { SpringApplication.run(MyApplication.class, args); } }
库中的类:
package com.myProject.customLibrary.configuration; import com.myProject.customLibrary.configuration.UserRepository.class; @Service public class CustomUserDetailsService implements UserDetailsService { private UserRepository userRepository; @Autowired public CustomUserDetailsService(UserRepository userRepository) { this.userRepository = userRepository; } ... package myProject.customLibrary.configuration; @Repository public interface UserRepository extends CustomRepository<User> { User findByLoginAndStatus(String var1, Status var2); ... }
刚刚找到解决方案。我没有定义要从单独的库进行扫描的基本包,而是仅在该库中创建了带有全部注释的配置类,并将其导入到我的主MyApplication.class中:
package runnableProject.application; import com.myProject.customLibrary.configuration.SharedConfigurationReference.class @SpringBootApplication @Import(SharedConfigurationReference.class) public class MyApplication { public static void main(String[] args) { SpringApplication.run(MyApplication.class, args); } } package com.myProject.customLibrary.configuration; @Configuration @ComponentScan("com.myProject.customLibrary.configuration") @EnableJpaRepositories("com.myProject.customLibrary.configuration.repository") @EntityScan("com.myProject.customLibrary.configuration.domain") public class SharedConfigurationReference {}
