java - 如果 Liquibase 因更改集迁移失败而失败，我的 csv 数据有什么问题...原因 : java. lang.NullPointerException

Question

堆栈跟踪是:

    Caused by: liquibase.exception.MigrationFailedException: Migration failed for change set config/liquibase/changelog/20190425094054_added_entity_Kindergarten.xml::20190425094054-1::jhipster:

数据是通过变更集中的此设置加载的:

        <loadData
        file="config/liquibase/data/kindergarten.csv"
        separator=";"
        tableName="kindergarten"/>

数据本身是:

1,4,xxx yyy 2  ,7 905 555-70-29,"rose place, 11г",john doe
2,7,103,"555-68-72, 555-68-73","address xxx 5, ",emett brown
3,2,34,555-28-49,"z street, 72",""

我已将所有空 ,, 更新为 ,"", 以包含空字符串而不是 null。

最后的问题是如何启用 liquibase 调试来定义数据中的哪一行包含空指针问题？现在我必须手动揭示有问题的原始数据

Answer 1

在您的变更集配置中，值 separator 设置为 ;，但您的 CSV 文件使用 , 作为分隔符。更正变更集配置中的值。
