1、添加依赖
<!-- jpa -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<!-- oracle数据库驱动 start -->
<dependency>
<groupId>com.oracle</groupId>
<artifactId>ojdbc6</artifactId>
<version>11.2.0.3</version>
</dependency>
2、在application.properties中添加数据源
#db 单数据源
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:ORCL
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
spring.jpa.show-sql= true
#1、无修改命名
spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
#2、遇到大写字母 加”_”的命名
#spring.jpa.hibernate.naming.physical-strategy=org.springframework.boot.orm.jpa.hibernate.SpringPhysicalNamingStrategy
3、创建实体类主键采用UUID策略
| javax.persistence.Table(name = "t_dynasty")@javax.persistence.Entity public class Dynasty { /** * id */ @Id @GenericGenerator(name ="system-uuid", strategy = "uuid") @GeneratedValue(generator = "system-uuid") @Column(name = "id") private String id; @Column(name = "name") private String name; @Column(name = "startYear") private String startYear; @Column(name = "endYear") private String endYear; @Column(name = "age") private Integer age; public String getId() { return id; } public void setId(String id) { this.id = id; } public String getName() { return name; } public void setName(String name) { this.name = name; } public String getStartYear() { return startYear; } public void setStartYear(String startYear) { this.startYear = startYear; } public String getEndYear() { return endYear; } public void setEndYear(String endYear) { this.endYear = endYear; } public Integer getAge() { return age; } public void setAge(Integer age) { this.age = age; }
} |
4、创建对应的接口repository继承JpaRepository<K,V>
| public interface DynastyRepository extends JpaRepository<Dynasty, Long>{
} |
5、创建相应的接口调用
| @RestController @RequestMapping("/dynasty") public class DynastyController {
@Autowired private DynastyRepository dynastyRepository;
@RequestMapping("/hello") public String hello() { return "success"; }
@RequestMapping("/findAll") public List<Dynasty> findAll() { List<Dynasty> dynastys =dynastyRepository.findAll(); return dynastys; }
@RequestMapping("/save") public String save(Dynasty dynasty) { dynastyRepository.save(dynasty); return "success"; } } |
