Spring Boot：从图书馆项目中自动导入bean

Question

我很努力从自定义库中自动导入bean，导入的是gradle。 阅读了几个类似的话题后，我仍然无法找到解决方案。

我有Spring Boot项目，依赖于其他项目（我的自定义库与组件，存储库等...）。这个库是一个Spring不可运行的jar，主要由域Entities和Repositories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）试图初始化，但自动装入的bean加载失败（接口UserRepository）...

错误：

Parameter 0 of constructor in com.myProject.customLibrary.configuration.CustomUserDetailsService required a bean of type 'com.myProject.customLibrary.configuration.UserRepository' that could not be found.

我甚至试图设置“订单”，到（与“scanBasePackageClasses”）显式装载它，使用包和标记扫描类，添加额外的'EnableJPARepository'注释，但没有任何作品...

代码示例（软件包的名称已更改为简单起见）

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); 
    } 

} 

类从库：

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); 

    ... 
}

就找到了解决办法。 而不是定义基本包由独立的库进行扫描的，我刚刚创建的配置类此库中有一大堆注解并将其导入到我的主要MyApplication.class：

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 { 
}
