问题：

从外部jar包含Spring上下文找不到服务

皇甫雨华
2023-03-14

我目前正在使用Spring Boot和基于注释的配置来管理我的Spring应用程序。该项目由注册和外部服务库组成。

服务由带有@Service注释的类组成，并在这些类中注入了@Reposity。

注册将注入@服务。

项目结构（4个maven项目）：

xelamitchell (Parent POM)
  +- domain
  +- service (Spring JPA)

registration (separate project with Spring Boot)

注册对服务有maven依赖。

个人服务：

package org.xelamitchell.service.person;

import org.xelamitchell.domain.person.Person;
import java.util.List;

/**
 * Manages {@link Person}s.
 * 
 * @author amitchell
 */
public interface PersonService {

    List<Person> list();

    Person get(Long id);

    Boolean exists(Long id);

    Person save(Person person);

    Boolean delete(Long id);

}

package org.xelamitchell.service.person;

import org.xelamitchell.domain.person.Person;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Primary;
import org.springframework.stereotype.Service;

/**
 *
 * @author amitchell
 */
@Primary
@Service
public class DefaultPersonService implements PersonService {

    private PersonRepository repository;

    protected DefaultPersonService() {}

    @Autowired
    public DefaultPersonService(PersonRepository repository) {
        this.repository = repository;
    }

    @Override
    public List<Person> list() {
        return repository.findAll();
    }

    @Override
    public Person get(Long id) {
        return repository.findOne(id);
    }

    @Override
    public Boolean exists(Long id) {
        return repository.exists(id);
    }

    @Override
    public Person save(Person person) {
        return repository.save(person);
    }

    @Override
    public Boolean delete(Long id) {

        if(id != null) {
            repository.delete(id);
        }

        return repository.exists(id);
    }

}

PersonRepository：

package org.xelamitchell.service.person;

import org.xelamitchell.domain.person.Person;
import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

/**
 *
 * @author amitchell
 */
@Repository
public interface PersonRepository extends JpaRepository<Person, Long> {

}

服务库配置：

@Configuration
public class ServiceContext {
}

应用程序配置：

@Configuration
@ComponentScan(basePackages = {"org.xelamitchell"})
@EnableAutoConfiguration
//@Import({WebContext.class, ServiceContext.class})
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

Spring boot在POM中定义用于应用。

我经常遇到的一个例外是，@Repository类无法被注入到它们各自的@Service：

找到它，在上面添加@Repository，并将此anotation从个性化存储库接口中删除。

讨论后编辑。。。

在应用程序类的顶部添加“@EnableJpaRepositories”和“@EntityScan”。

@EnableJpaRepositories("org.xelamitchell")
@EntityScan("org.xelamitchell")

嗯。。。
