我已经在Configs中将持久存储从H2更改为MYSQL，但是点燃实例没有启动。
private int drawableResourceId = R.drawable.default_menu_icon;
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.test_menu, menu);
menu.findItem(R.id.change_menu_item_icon).setIcon(drawableResourceId);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.change_menu_item_icon:
drawableResourceId = R.drawable.changed_menu_icon;
invalidateOptionsMenu();
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
控制台只给我这些

考虑内存H2数据库中的默认值
在配置中没有任何地方定义数据源的bean用作引用。如果我错了，请更正我，但根据我的理解，缓存存储只具有向缓存加载数据和从缓存加载数据的作用，并且不处理选择持久性商店。如何点燃对持久性商店的理解？
答案 0 :(得分：0)
缓存存储器负责从数据库加载数据和读/写。有关详细信息，请参见[1]。
如果使用CacheJdbcPojoStore，您可以提供数据源Spring bean的名称，商店将提取它：
CacheJdbcPojoStoreFactory<Long, Person> storeFactory = new CacheJdbcPojoStoreFactory<>();
storeFactory.setDataSourceBean("mysql-example-db");
