/project
4. 创建配置文件
resources目录下创建application.yml。
server:port: 8090
spring:redis:host: localhostport: 6379database: 0
5. 创建Constants常量类
com.wfit.boot.commons目录下创建Constants.java。
public class Constants {// 默认成功码public static final int SUCCESS_CODE 200;public static final String SUCCESS_MSG 操作成功;// 默认失败码public static final int ERROR_CODE 500;public static final String ERROR_MSG 系统异常;
}
6. 创建Result类
com.wfit.boot.commons目录下创建Result.java。
Data
NoArgsConstructor
AllArgsConstructor
public class ResultT {//响应码private int code;//响应消息private String msg;//响应结果private T data;public static T ResultT success(T data){return new Result(Constants.SUCCESS_CODE,Constants.SUCCESS_MSG,data);}public static T ResultT error(T data){return new Result(Constants.ERROR_CODE,Constants.ERROR_MSG,data);}}
7. 创建Book实体类
com.wfit.boot.model目录下创建Book.java。
Data
public class Book implements Serializable {private String id;private String name;private String author;}
8. 创建BookController类
com.wfit.boot.controller目录下创建BookController.java。
RestController
RequestMapping(/book)
public class BookController {Autowiredprivate BookService bookService;/*** 新增图书信息* param book* return*/PostMapping(/add)public Result addBook(RequestBody Book book){bookService.addBook(book);return Result.success(新增图书信息成功);}/*** 查询图书信息*/GetMapping(/query)public Result query(String id){Book book bookService.queryBook(id);return Result.success(book);}
}
9. 创建BookService接口
com.wfit.boot.service目录下创建BookService.java。
public interface BookService {public void addBook(Book book);public Book queryBook(String id);}
10. 创建BookServiceImpl类
com.wfit.boot.service.impl目录下创建BookServiceImpl.java。
Service
public class StudentServiceImpl implements StudentService {Resourceprivate RedisTemplateString,Object redisTemplate;Overridepublic void addStudent(Student student) {redisTemplate.opsForValue().set(student.getId(),student);}Overridepublic Student queryStudent(String id) {return (Student)redisTemplate.opsForValue().get(id);}
}
11. 案例测试 测试新增图书信息 测试查询图书信息
