Spring Boot-Web应用程序无法停止MVStore writer线程

我在spring boot应用程序中使用嵌入式H2数据库,但每次关机时,数据库都不会像我在中配置的那样正确关闭/删除 application.properties . 以下是关闭应用程序时出现的错误:

2018-02-05 13:00:37.360 WARN  [localhost-startStop-2] [WebappClassLoaderBase] 
     The web application [ROOT] appears to have started a 
     thread named [MVStore background writer nio:C:/Users/user/testdb.mv.db] but has failed to stop it. 
     This is very likely to create a memory leak. Stack trace of thread:
 java.lang.Object.wait(Native Method)
 org.h2.mvstore.MVStore$BackgroundWriterThread.run(MVStore.java:2715)

其效果是文件testdb。mv保留在我的用户目录中,在随后的启动中

org.h2.jdbc.JdbcSQLException: Unique index or primary key violation: "PRIMARY KEY ON PUBLIC.USERS(ID)"; SQL statement:
INSERT INTO Users (id,first_name,last_name) VALUES (1,'Vincent', 'Vega') [23505-196]
    at org.h2.message.DbException.getJdbcSQLException(DbException.java:345)
    at org.h2.message.DbException.get(DbException.java:179)

这是 data.sql 启动时运行的脚本

INSERT INTO Users (id,first_name,last_name) VALUES (1,'Vincent', 'Vega');

这是 User 定义 @Table("Users")

@Entity
@Table(name="Users")
public class User 
{
    @Id
    @GeneratedValue
    private long id;

    @Column(name="first_name")
    private String firstName;

    @Column(name="last_name")
    private String lastName;
    /* getters and setters */
}

这些是中的h2相关配置 应用属性

spring.jpa.generate-ddl=true
spring.jpa.hibernate.ddl-auto=none 
spring.jpa.database=H2
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.show-sql=true
spring.datasource.driverClassName=org.h2.Driver
spring.datasource.url=jdbc:h2:~/testdb;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=TRUE
spring.datasource.name=testdb
spring.h2.console.enabled=true
spring.h2.console.path=/h2-console

谢谢你的帮助
