private static Logger logger = LoggerFactory.getLogger(DbShardingAlgorithm.class);
Map<String, String> dealerDSMap = ImmutableMap.of("d16df3743a", "ds0",
"bc0ce9b058", "ds1",
"85abb5f5d2", "ds2",
"b563165232", "ds3",
"f0f198b56d", "ds4");
@Override
public String doSharding(Collection collection, PreciseShardingValue preciseShardingValue) {
if ("dealer_id".equals(preciseShardingValue.getColumnName())) {
String dealerId = (String) preciseShardingValue.getValue();
return dealerDSMap.get(dealerId);
}
return "ds0";
}
}
when i set the class file to the proxy home dir. got a error message:
> java.lang.ClassNotFoundException: io.shardingsphere.api.algorithm.sharding.standard.PreciseShardingAlgorithm

the latest version？which？4.0.0-RC3？
the latest version‘s package is `org.apache.shardingsphere.xxx.xxx`, but your exception is `io.shardingsphere`, this is a very old version.
Please make sure your version firstly.
