五、springboot（二）配置数据源oracle

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::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
 
　　#、无修改命名
 
   spring.jpa.hibernate.naming.physical-strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl
 
　　#、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";
 
 }
 
}
