“java.lang.IllegalArgumentException：不是托管类型...”当实体类和Spring数据存储库在同一个包中时

标签： java spring spring-boot dependency-injection autowired

我的简单Spring应用程序中有一个非常奇怪的行为。我无法在同一个软件包中安装JPA实体和Spring Data Repository。

我想构建一个非常简单的Web应用程序，我在其中管理一些用户。所以我从头开始创建了以下项目结构：

package de.my.mainpackage.core.user;

import lombok.AllArgsConstructor;
import lombok.Data;
import lombok.NoArgsConstructor;

import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.Id;

@Entity
@Data
@NoArgsConstructor
@AllArgsConstructor
public class User {
    @Id
    @GeneratedValue
    private Long id;

    private String username;
    private String password;
    private String email;
}

User.java代码：

package de.my.mainpackage.core.user;

import org.springframework.data.jpa.repository.JpaRepository;
import org.springframework.stereotype.Repository;

@Repository
public interface UserRepository extends JpaRepository<User, Long>{
}

UserRepository.java代码：

package de.my.mainpackage.client;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import de.my.mainpackage.core.user.UserRepository;
import org.springframework.context.ApplicationContext;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;


@SpringBootApplication
@EnableJpaRepositories("de.my.mainpackage.core.user")
public class ClientApp {

   @Autowired
   private UserRepository userRepository;

    public static void main(String[] args) {
        ApplicationContext applicationContext = SpringApplication.run(ClientApp.class, args);
        ClientApp clientApp = (ClientApp)applicationContext.getBean("clientApp");

        System.out.println("userRepository is = " + clientApp.userRepository);
    }
}

ClientApp.java代码：

所以我的想法是将模型和存储库分成一个自己的目录core.user，而主应用程序逻辑应该保留在客户端子文件夹中。但是，当我使用此配置运行Spring应用程序时，出现以下错误：

UserRepository

为了使ClientApp可用@EnableJpaRepositories("de.my.mainpackage.core.user")，我添加了 src | +-- main | +-- de.my.mainpackage | +-- client | | | +-- ClientApp.java | | | +-- User.java | +-- core | +-- user | | +-- UserRepository.java 。现在奇怪的是：

当我将User.java移动到客户端子包时，它工作正常。 像这样：

            //Ensure that only apply if it is a SearchView and if it is visible.
            return allOf(isDisplayed(), isAssignableFrom(SearchView.class));
        }

        @Override
        public String getDescription() {
            return "Change view text";
        }

        @Override
        public void perform(UiController uiController, View view) {
            ((SearchView) view).setQuery(text,false);
        }
    };
}

所以，我花了很多时间试图找出我做错了什么......没有想法。

谢谢@JB Nizet：

我想，通过使用正确的软件包设置 @EnableJpaRepositories 和 @ComponentScan ，这就足够了。我不知道，对于你需要的实体， @EntityScan 。非常感谢你的提示！
