事件虽然内置的H2
EmbeddedDatabaseConfigurerDB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=falseAbstractEmbeddedDatabaseConfigurer.shutdown()stackoverflow 上已经有很多关于这个主题的讨论。我尝试了一下这些选项，并得出结论，自定义 DB_CLOSE_DELAY=20;DB_CLOSE_ON_EXIT=false 提供的相当
奇怪的设置(
DataSourceFactory/**
* This factory tries to solve the problem that Spring tries to close a data source that has already been closed by the H2 engine/H2 driver.
*/
public class H2DataSourceFactory implements DataSourceFactory {
private final SimpleDriverDataSource dataSource = new SimpleDriverDataSource();
@Override
public ConnectionProperties getConnectionProperties() {
return new ConnectionProperties() {
@Override
public void setDriverClass(Class<? extends Driver> driverClass) {
dataSource.setDriverClass(driverClass);
}
@Override
public void setUrl(String url) {
// ignore the URL and use a custom URL
dataSource.setUrl("jdbc:h2:mem:%s;DB_CLOSE_DELAY=20;DB_CLOSE_ON_EXIT=false;MODE=PostgreSQL");
}
@Override
public void setUsername(String username) {
dataSource.setUsername(username);
}
@Override
public void setPassword(String password) {
dataSource.setPassword(password);
}
};
}
@Override
public DataSource getDataSource() {
return this.dataSource;
}
}
其他人有没有找到真正消除这种影响的解决方案？

对于仍然面临这个问题的人：
使用
async您可以将其设置为：
spring.datasource.url=jdbc:h2:async:mem:testdb
