Spring Boot：库项目中的autowire bean

Question

我正在努力从我的自定义库中自动生成bean，这是和Gradle一起导入的。读了几个类似的题目后，我仍然无法找到解决方法。

我有一个Spring Boot项目，它依赖于另一个项目（我的带有组件、存储库等的自定义库）。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...

错误：

Com.MyProject.CustomLibrary.Configuration.CustomUserDetailsService中的构造函数的参数0需要类型为“Com.MyProject.CustomLibrary.Configuration.UserRepository”的bean，但找不到该bean。

我甚至尝试设置“order”，显式加载它（使用ScanBasePackageClasses)，使用包和标记类进行扫描，添加其他EnableJPararePository注释，但没有任何效果...

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);

    ...
}

刚找到解决办法。我没有定义要从单独的库中扫描的基本包,而是在这个库中创建了配置类,并将其导入到我的主MyApplication.class中：

java prettyprint-override">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 {}
