弹簧靴，JPA。存储库不是托管类型

Question

我使用 Spring boot + jpa + h2 并且我遇到了这个异常：

原因：org.springframework.beans.factory.BeanCreationException：创建名为“userRepository”的bean时出错：调用init方法失败；嵌套异常是 java.lang.IllegalArgumentException: Not a managed type: class com.campsite.users.model.User

应用程序.java 文件：

package com.campsite.users.server;

import org.springframework.boot.SpringApplication;

import org.springframework.boot.autoconfigure.EnableAutoConfiguration;

import org.springframework.boot.autoconfigure.SpringBootApplication;

import org.springframework.boot.builder.SpringApplicationBuilder;

import org.springframework.boot.web.support.SpringBootServletInitializer;

import org.springframework.context.annotation.ComponentScan;

import org.springframework.context.annotation.ComponentScans;

import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

/**

 * Class that starts the Springboot Application

 */

@EnableAutoConfiguration

@SpringBootApplication

@ComponentScan({"com.campsite.users.server", "com.campsite.users.controller","com.campsite.users.manager", "com.campsite.users.model"})

@EnableJpaRepositories("com.campsite.users.repository")

public class Application extends SpringBootServletInitializer {

    @Override

    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {

        return application.sources(Application.class);

    }

    public static void main(String[] args) throws Exception {

        SpringApplication.run(Application.class, args);

    }

}

ApplicationContext.java 文件：

package com.campsite.users.server;

import org.springframework.beans.factory.annotation.Value;

import org.springframework.context.annotation.Bean;

import org.springframework.context.annotation.Configuration;

@Configuration

public class ApplicationContext {

    // inject via application.properties

    @Value("${campsite.module.name}")

    private String moduleName;

    @Bean

    public String getModuleName(){

        return this.moduleName;

    }

我对此感到非常失落。我检查了另一个stackoverflow问题，但我无法找到我所缺少的。

@ComponentScan({"com.campsite.users.server", "com.campsite.users.controller","com.campsite.users.manager", "com.campsite.users.model"})@EnableJpaRepositories("com.campsite.users.repository")我认为您在启动 SpringBoot 应用程序时不需要添加这些注释。你为什么不试试没有它们呢？此外，将您的应用程序类移动到 com.campsite.users。
