带有Spring-boot CLI的RepositoryRestResource（springboot包含）

我正在尝试基于具有spring-boot和spring-data-
rest的JPA存储库实现一个简单的REST服务。（请参阅本教程）如果将下面的代码与gradle一起使用，则效果很好：

package ch.bfh.swos.bookappimport org.springframework.boot.SpringApplicationimport org.springframework.boot.autoconfigure.EnableAutoConfigurationimport org.springframework.context.annotation.*import org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfigurationimport org.springframework.data.jpa.repository.config.EnableJpaRepositoriesimport org.springframework.context.annotation.Importimport org.springframework.data.rest.core.annotation.RepositoryRestResourceimport org.springframework.data.repository.CrudRepositoryimport javax.persistence.*@Configuration@ComponentScan@EnableAutoConfiguration@EnableJpaRepositories@Import(RepositoryRestMvcConfiguration.class)class Application {    static void main(String[] args) {        SpringApplication.run Application, args    }}@RepositoryRestResource(path = "authors")interface AuthorRepository extends CrudRepository<Author, Long> {}@Entityclass Author {    @Id    @GeneratedValue(strategy = GenerationType.AUTO)    private Long id    private String firstname    private String lastname}

为了使事情更简单，我尝试了使用spring boot CLI（“ spring run”命令）使用相同的代码。

package ch.bfh.swos.bookapp@Grab("spring-boot-starter-data-jpa")@Grab("spring-boot-starter-data-rest")@Grab("h2")import org.springframework.boot.autoconfigure.EnableAutoConfigurationimport org.springframework.context.annotation.ComponentScanimport org.springframework.context.annotation.Configurationimport org.springframework.data.rest.webmvc.config.RepositoryRestMvcConfigurationimport org.springframework.data.jpa.repository.config.EnableJpaRepositoriesimport org.springframework.context.annotation.Importimport org.springframework.data.rest.core.annotation.RepositoryRestResourceimport org.springframework.data.repository.CrudRepositoryimport javax.persistence.*@Configuration@ComponentScan@EnableAutoConfiguration@EnableJpaRepositories@Import(RepositoryRestMvcConfiguration.class)@RepositoryRestResource(path = "authors")interface AuthorRepository extends CrudRepository<Author, Long> {}@Entityclass Author {    @Id    @GeneratedValue(strategy = GenerationType.AUTO)    private Long id    private String firstname    private String lastname}

不幸的是，这似乎不起作用。@RepositoryRestResource似乎不会像@RestController这样被自动识别。保留@Configuration部分，服务器将启动，但不会像使用gradle那样创建REST存储库。

有人知道是否可以使用spring-boot CLI创建RepositoryRestResource，以及正确的代码应如何显示？

您需要一个类定义来挂起它@Import（其他在类上而不是在接口上的注释是多余的）。

更新： 并且
（更重要的是）除非它们实际上在文件中，否则Hibernate无法找到带注释的类（它注释性地分析字节码而不是类定义）。因此，您可以通过加扰并以这种方式运行它来使您的应用工作：

$ spring jar app.jar app.groovy$ java -jar app.jar

这是该应用程序的较短版本，其工作方式与删除所有多余内容的方式相同：

package bookapp@Grab("spring-boot-starter-data-jpa")@Grab("spring-boot-starter-data-rest")@Grab("h2")import org.springframework.data.rest.core.annotation.RepositoryRestResourceimport org.springframework.data.repository.CrudRepositoryimport javax.persistence.*@Configurationclass App {}@RepositoryRestResource(path = "authors")interface AuthorRepository extends CrudRepository<Author, Long> {}@Entityclass Author {  @Id  @GeneratedValue(strategy = GenerationType.AUTO)  private Long id  String firstname  String lastname}

A ResourcePool could not acquire a resource from its primary factory or source.

严重: Servlet.service () for servlet [dispatcherServlet] in context with path [/heima_ssm_web1] threw exception [Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.exceptions.PersistenceException:
### Error querying database. Cause: org.springframework.jdbc.CannotGetJdbcConnectionException: Failed to obtain JDBC Connection; nested exception is java.sql.SQLException: Connections could not be acquired from the underlying database!
### The error may exist in com/itheima/ssm/dao/IProductDao.java (best guess)
### The error may involve com.itheima.ssm.dao.IProductDao.findAll
### The error occurred while executing a query

问题解决

1. 检查数据库配置；

2. 如果你和我一样也是虚拟机中的数据库，检查虚拟机中数据库是否还能链接

c# – 关于resources.ApplyResources的System.Resources.MissingManifestResourceException

System.ComponentModel.ComponentResourceManager resources = new System.ComponentModel.ComponentResourceManager(typeof(EditorPane));
this.editorControl = new EditorControl();
resources.ApplyResources(this.editorControl,"editorControl",CultureInfo.CurrentUICulture);
