表结构是对的呢?哪里不对,帮忙指出
from dtmcli-java-sample.
首先在本地库执行了 https://github.com/dtm-labs/dtm/blob/main/sqls/busi.mysql.sql 这段sql
然后java sample里
1.application.yml 文件使用的库名:
datasource:
url: jdbc:mysql://localhost:3306/dtm_barrier?useUnicode=true&characterEncoding=utf-8&useSSL=true&serverTimezone=UTC
把‘dtm_barrier’改为‘dtm_busi’了
2.代码 TransBarrierController.java : 169 中使用的SQL语句:
String sql = "update dtm_busi.user_account set trading_balance=trading_balance-?,balance=balance+? where user_id=?";
运行 DtmcliJavaSampleApplication.java ,执行 curl localhost:8081/api/tccBarrier 有报错

at com.mysql.cj.jdbc.exceptions.SQLExceptionsMapping.translateException(SQLExceptionsMapping.java:122) ~[mysql-connector-java-8.0.26.jar:8.0.26]
java demo代码里用到的表,在sql文件里名字没对上
from dtmcli-java-sample.
又找到一段建 barrier 表的sql,https://github.com/dtm-labs/dtm/blob/main/sqls/dtmcli.barrier.mysql.sql
执行完代码能用了
建议在readme加上说明以及两个sql的链接
from dtmcli-java-sample.
