问题：

 

 

解决：

1. 创建好数据库及表
2. 在 spring boot 项目 pom.xml 引入 spring data rest depency
   
   <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-rest</artifactId> </dependency> <!-- 如加入下边 hal-explorer 则会集成一个类似 swagger ui 一样的接口浏览器，通过接口根目录访问 --> <dependency> <groupId>org.springframework.data</groupId> <artifactId>spring-data-rest-hal-explorer</artifactId> </dependency>

   1 2 3 4 5 6 7 8 9 10

   <dependency>             <groupId>org.springframework.boot</groupId>             <artifactId>spring-boot-starter-data-rest</artifactId>         </dependency>   <!-- 如加入下边 hal-explorer 则会集成一个类似 swagger ui 一样的接口浏览器，通过接口根目录访问 --> <dependency>     <groupId>org.springframework.data</groupId>     <artifactId>spring-data-rest-hal-explorer</artifactId>   </dependency>

   
    
3. 中创建好 Entity Class
4. 创建 repo 如：
   
   @RepositoryRestResource(collectionResourceRel = "company", path = "company") public interface CompanyRestRepo extends PagingAndSortingRepository<Company, String>, CrudRepository<Company, String> { Page<Company> findByType(String type, Pageable p);//定制查询方法 可通过 .../company/search/findByType?type=*** 访问 }

   1 2 3 4 5 6

   @RepositoryRestResource(collectionResourceRel = "company", path = "company") public interface CompanyRestRepo extends PagingAndSortingRepository<Company, String>,         CrudRepository<Company, String> {     Page<Company> findByType(String type, Pageable p);//定制查询方法 可通过 .../company/search/findByType?type=*** 访问   }

   
    
5. 然后就可以 用 rest 的方式交互了。如使用 post json 创建数据；
   
   curl --request 'POST' --location 'http://localhost:8080/company' \ --header 'Content-Type: application/json' \ --data '{ "name": "中国石化" }'

   1 2 3 4 5

   curl --request 'POST' --location 'http://localhost:8080/company' \ --header 'Content-Type: application/json' \ --data '{     "name": "中国石化"     }'

   
   GET 直接列出数据如：
   
   curl --location 'http://localhost:8080/company?page=0&size=20'

   1	curl --location 'http://localhost:8080/company?page=0&size=20'

   
   
   curl --location 'http://localhost:8080/company/search/findByType?type=aa&page=0&size=20'

   1	curl --location 'http://localhost:8080/company/search/findByType?type=aa&page=0&size=20'

   
    

   ；PUT 修改数据如：

   curl --location --request PUT 'http://localhost:8080/company/600028' \ --header 'Content-Type: application/json' \ --data '{ "name": "中国石化" }'

   1 2 3 4 5

   curl --location --request PUT 'http://localhost:8080/company/600028' \ --header 'Content-Type: application/json' \ --data '{     "name": "中国石化" }'

    

6. end
