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;@Configurationpublic 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。

Answer 1

@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。
