簡單查詢

spring data jpa是spring全家桶成員之一，用于操作各種數(shù)據(jù)庫，下面寫一個查詢訂單的簡單示例

引入sqlserver驅(qū)動包及jpa所需包

implementation('org.springframework.boot:spring-boot-starter-data-jpa')runtimeOnly('com.microsoft.sqlserver:mssql-jdbc')

2.配置連接字符串

spring.datasource.url=jdbc:sqlserver://machinename or ip:1433;database=dbname spring.datasource.username=username spring.datasource.password=password spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl #關(guān)閉初始化數(shù)據(jù)庫 spring.jpa.generate-ddl=false #顯示生成的sql spring.jpa.show-sql=true

3.創(chuàng)建entity，可用idea生成

@Entity @Table(name = "Order", schema = "dbo") class OrderEntity {@get:Id@get:Column(name = "OrderID")var orderId: String? = null@get:Basic@get:Column(name = "OrderStatus")var orderStatus: Byte = 0@get:Basic@get:Column(name = "OrderDate")var orderDate: LocalDateTime? = null@get:Basic@get:Column(name = "CurrencyCode")var currencyCode: String? = null@get:Basic@get:Column(name = "OrderAmount")var orderAmount: BigDecimal? = null }

4.創(chuàng)建repository

@Repository interface OrderRepository:JpaRepository<OrderEntity,String>

可以簡單調(diào)用一下了

@Autowiredprivate lateinit var orderRepository: OrderRepositoryorderRepository.findAll()
