SpringBoot集成SQL Server的详细指南
作者:HBLOG
SQL Server是由Microsoft开发和推广的以客户/服务器(c/s)模式访问、使用Transact-SQL语言的关系数据库管理系统(DBMS),本文给大家介绍了Spring Boot集成SQL Server的详细指南,需要的朋友可以参考下
1.什么是SQL Server?
SQL Server是由Microsoft开发和推广的以客户/服务器(c/s)模式访问、使用Transact-SQL语言的关系数据库管理系统(DBMS),它最初是由Microsoft、Sybase和Ashton-Tate三家公司共同开发的,并于1988年推出了第一个OS/2版本。Microsoft SQL Server近年来不断更新版本,1996年,Microsoft 推出了SQL Server 6.5版本;1998年,SQL Server 7.0版本和用户见面;SQL Server 2000是Microsoft公司于2000年推出,目前最新版本是2019年份推出的SQL SERVER 2019。 提供的主要功能:
- 支持存储过程、触发器、函数和视图
- 本机支持关系数据、XML、FILESTREAM 和空间数据,可存储所有类型的业务数据
- 除与 SQL Server Reporting Services 中的 Microsoft 2007 Office System 集成外,还改进了性能、可用性、可视化
- 通过利用现有的 T-SQL 技术、ADO.NET 实体框架和 LINQ 简化开发工作
- 与 Visual Studio 和 Visual Web Developer 紧密集成
SQL Server 2019 更是使用统一的数据平台实现业务转型,附带 Apache Spark 和 Hadoop Distributed File System(HDFS),可实现所有数据的智能化。
2.环境搭建
pull images
sudo docker pull mcr.microsoft.com/mssql/server:2022-latest
create a container
docker run -e "ACCEPT_EULA=Y" -e "SA_PASSWORD=Y.sa123456" -p 1433:1433 --name mssql2022 -d mcr.microsoft.com/mssql/server:2022-latest
default user/password: sa / Y.sa123456
init datas
CREATE DATABASE SampleDB; USE SampleDB; #JPA AUTO CREATE TABLE INSERT INTO Employees (first_name, last_name, birth_date, hire_date, position) VALUES ('John', 'Doe', '1980-01-15', '2010-06-01', 'Manager'), ('Jane', 'Smith', '1990-07-22', '2015-09-15', 'Developer'), ('Emily', 'Jones', '1985-03-10', '2012-11-20', 'Designer');
3.代码工程
实验目的
Spring Boot对SQL Server 数据库CRUD 操作
pom.xml

controller
package com.et.controller; import com.et.entity.Employee; import com.et.service.EmployeeService; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.http.ResponseEntity; import org.springframework.web.bind.annotation.*; import java.util.List; @RestController @RequestMapping("/api/employees") public class EmployeeController { @Autowired private EmployeeService employeeService; @GetMapping public List<Employee> getAllEmployees() { return employeeService.getAllEmployees(); } @GetMapping("/{id}") public ResponseEntity<Employee> getEmployeeById(@PathVariable Integer id) { return employeeService.getEmployeeById(id) .map(ResponseEntity::ok) .orElse(ResponseEntity.notFound().build()); } @PostMapping public Employee addEmployee(@RequestBody Employee employee) { return employeeService.addEmployee(employee); } @PutMapping("/{id}") public ResponseEntity<Employee> updateEmployee(@PathVariable Integer id, @RequestBody Employee employeeDetails) { return ResponseEntity.ok(employeeService.updateEmployee(id, employeeDetails)); } @DeleteMapping("/{id}") public ResponseEntity<Void> deleteEmployee(@PathVariable Integer id) { employeeService.deleteEmployee(id); return ResponseEntity.noContent().build(); } }
service
package com.et.service; import com.et.entity.Employee; import com.et.reponsitory.EmployeeRepository; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; import java.util.List; import java.util.NoSuchElementException; import java.util.Optional; @Service public class EmployeeService { @Autowired private EmployeeRepository employeeRepository; public List<Employee> getAllEmployees() { return employeeRepository.findAll(); } public Optional<Employee> getEmployeeById(Integer id) { return employeeRepository.findById(id); } public Employee addEmployee(Employee employee) { return employeeRepository.save(employee); } public Employee updateEmployee(Integer id, Employee employeeDetails) { Employee employee = employeeRepository.findById(id).orElseThrow(RuntimeException::new); employee.setFirstName(employeeDetails.getFirstName()); employee.setLastName(employeeDetails.getLastName()); employee.setBirthDate(employeeDetails.getBirthDate()); employee.setHireDate(employeeDetails.getHireDate()); employee.setPosition(employeeDetails.getPosition()); return employeeRepository.save(employee); } public void deleteEmployee(Integer id) { employeeRepository.deleteById(id); } }
reponsitory
package com.et.reponsitory; import com.et.entity.Employee; import org.springframework.data.jpa.repository.JpaRepository; public interface EmployeeRepository extends JpaRepository<Employee, Integer> { }
application.properties
server.port=8088 spring.datasource.url=jdbc:sqlserver://127.0.0.1:1433;databaseName=SampleDB spring.datasource.username=sa spring.datasource.password=Y.sa123456 spring.jpa.hibernate.ddl-auto=create spring.jpa.show-sql=true
