Mysql sub-table springBoot uses shardingsphere - sub-database sub-table

Generate workerId

import cn.hutool.core.net.NetUtil;
import lombok.extern.slf4j.Slf4j;
import org.springframework.context.annotation.Configuration;

@Configuration
@Slf4j
public class WorkerIdConfiguration {
    
    

    private static String WORKER_ID = "workerId";

    static {
    
    
        long workerId = 0;
        try {
    
    
            String hostAddress = NetUtil.getLocalhostStr();
            log.info("============= 当前机器 hostAddress: {} =============", hostAddress);
            int[] ints = org.apache.commons.lang3.StringUtils.toCodePoints(hostAddress);
            int sums = 0;
            int[] var3 = ints;
            int var4 = ints.length;

            for(int var5 = 0; var5 < var4; ++var5) {
    
    
                int b = var3[var5];
                sums += b;
            }

            workerId = (long)(sums % 32);
            log.info("============== 当前机器 workerId：{} =============", workerId);
        } catch (Exception e) {
    
    
            log.warn("获取机器 workerId 失败", e);
        }
        System.setProperty(WORKER_ID, String.valueOf(workerId));
    }
}

Use the SQL statement to insert according to the table name of the undivided table. Note that all curd operations must have a subtable field as a parameter

 	    public static final String TABLE = "invite_friends_record";

        public static String insert() {
    
    
            return "INSERT INTO " + TABLE + " (`userId`, `friendId`, `appName`)"
                    + " VALUES (#{userId}, #{friendId}, #{appName})"
                    + " ON DUPLICATE KEY UPDATE"
                    + " `id` = `id`";
        }
