Answer 1

将org.h2.jdbcx.JdbcDataSource.class添加为类型帮助。

public DataSource h2() {
    String url = "jdbc:h2:mem:mydatabase;DB_CLOSE_DELAY=-1;DB_CLOSE_ON_EXIT=FALSE";
    return DataSourceBuilder.create()
            .url(url)
            .driverClassName("org.h2.Driver")
            .type(org.h2.jdbcx.JdbcDataSource.class) //xa datasource
            .build();
}
