What kind of change does this PR introduce? (check at least one)

The description of the PR: 1、closeDataSource方法进来默认直接把数据源dataSource 赋值给 realDatasource。下面if...else条件如果为真，realDatasource会被重新赋值，不影响原来的逻辑。 2、如果dataSource 是Druid等其他的数据源，也能够被closed。

不喜欢提前赋值的这种方式

[shen3]

DataSource realDataSource = null; if (dataSource instanceof ItemDataSource) { realDataSource = ((ItemDataSource) dataSource).getRealDataSource(); } else { if (seata) { if (dataSource instanceof DataSourceProxy) { DataSourceProxy dataSourceProxy = (DataSourceProxy) dataSource; realDataSource = dataSourceProxy.getTargetDataSource(); } } if (p6spy) { if (dataSource instanceof P6DataSource) { Field realDataSourceField = P6DataSource.class.getDeclaredField("realDataSource"); realDataSourceField.setAccessible(true); realDataSource = (DataSource) realDataSourceField.get(dataSource); } } }

这种？

if (null == realDataSource) { realDataSource = dataSource; }

if (null != realDataSource) { DataSourceDestroyer destroyer = new DefaultDataSourceDestroyer(); if (graceDestroy) { destroyer.asyncDestroy(ds, realDataSource); } else { destroyer.destroy(ds, realDataSource); } }
