無法使用postgres DB確定數據庫類型爲NONE的嵌入式數據庫驅動程序類

Question

在eclipse中運行彈簧引導應用程序時，出現錯誤「無法確定數據庫類型爲NONE的嵌入式數據庫驅動程序類」。 我有搜索網站，但找不到有用的東西。請參閱下面的代碼： -

Application.properties

server.port=9093 
spring.datasource.url=jdbc:postgresql://localhost:5432/DB 
spring.datasource.username=postgres 
spring.datasource.password=Sunny@310591 
spring.jpa.hibernate.ddl-auto=create-drop 
spring.jpa.database-platform=org.hibernate.dialect.PostgreSQLDialect 
logging.level.org.springframework.web=INFO 
logging.level.com.ge.punemmf.qualityputaway=DEBUG 
logging.level.org.hibernate=ERROR 
logging.file=logs/spring-boot-logging.log 
spring.database.driverClassName=org.postgresql.Driver 
endpoints.sensitive=false 

Application.java

@SpringBootApplication 
@EntityScan(basePackageClasses = { CenterOfExcellence.class, WorkOrder.class }) 
public class WarehouseVisibilityApplication { 

    public static void main(String[] args) { 
     SpringApplication.run(WarehouseVisibilityApplication.class, args); 
    } 
} 

CenterOfExcellence.java

@Entity 
@Table(name = "CENTEROFEXCELLENCE") 
public class CenterOfExcellence { 
    @Id 
    @GeneratedValue(strategy = GenerationType.IDENTITY) 
    private int id; 
    private String name; 
    @OneToMany 
    @JoinTable(name = "CENTEROFEXCELLENCE_WORKORDER", 
    joinColumns = @JoinColumn(name = "center_of_excellence_id"), inverseJoinColumns = @JoinColumn(name = "workorder_id")) 
    private Set<WorkOrder> workorders; 

} 

WorkOrder.java

@Entity 
@Table(name = "WORKORDER") 
public class WorkOrder { 
    @Id 
    @GeneratedValue(strategy=GenerationType.IDENTITY) 
    private int id; 
    private String workOrder; 
}

錯誤： -

說明：

數據庫類型不能確定嵌入式數據庫驅動程序類沒有

操作：

如果你想要一個嵌入式數據庫，請把classpath中的支持之一。如果您要從特定配置文件加載數據庫設置，則可能需要激活它（沒有配置文件當前處於活動狀態）。

Answer 1

此消息出現時，彈簧不能看到application.properties（和科西嘉沒有嵌入式數據庫組） 爲了驗證：確保所採取的端口是9093不是默認的8080
