IDEA的yml文件中文注释变问号#？？？

打开file->settings -> editor -> file encodings, 发现里面的global encoding 是utf-8编码没错，应用后退出，open项目，去settings里确认一下当前项目的encoding是不是也改了。当我关闭项目重新打开的时候，发现里面的yml 里中文注释变成 #？那么直接把当前三个编码格式都改成UTF-8 ，prop旁边的对钩也勾上。回头把中文注释补上，保存，close open项目几遍试试，下面的prop编码是跟随系统的，也没勾对钩。
什么是死锁？死锁产生的条件？如何避免或解决死锁？深入探讨死锁以及它的成因及解决方案
智通全网络工作室的博客
09-28 2720
简单来说，死锁（Deadlock）是一种现象，多个进程因为竞争资源而造成的相互等待的状态。这个状态下，每个进程都在等待其他进程释放资源，并且都无法继续执行，最终导致程序的停滞。可以想象成几个小船在某个狭窄水域中，彼此堵住，谁也无法前进。死锁是并发编程中不可避免的一个问题，但我们可以通过合理的设计、清晰的资源管理以及定期的健康检查来避免或解决它。希望这篇文章能够帮助大家更好地理解死锁的产生、条件以及应对策略，保障我们的应用程序能够正常、安全地运行。

这个错误信息： ``` org.postgresql.util.PSQLException: ERROR: syntax error at or near ")" ``` 表明你在执行 SQL 插入语句时，SQL 语法中存在错误，**括号 `)` 附近有语法错误**。 --- ### ❗问题定位： 从你提供的 SQL 片段来看： ```sql insert into ehsdata.p_cer_data (site,cer_one,cer_two,cer_type,cer_name,end_time,status,create_time) values (?, ?, ?, ?, ?, ?, ?, ?, ), -- 注意这里最后多了一个逗号 ... ``` 你插入语句中每个 `values` 后面的括号中都多了一个 **多余的逗号 `,`**，例如： ```sql (?, ?, ?, ?, ?, ?, ?, ?, ), -- 多余的逗号导致 PostgreSQL 报错 ``` PostgreSQL 无法识别这个语法，因此报错： > `syntax error at or near ")"` --- ### ✅ 解决方案： #### 修改 SQL，删除每个 `values` 中多余的逗号： **错误写法：** ```sql values (?, ?, ?, ?, ?, ?, ?, ?, ), -- 错误：多了一个逗号 ``` **正确写法：** ```sql values (?, ?, ?, ?, ?, ?, ?, ?), -- 正确：没有多余的逗号 ``` 确保每个 `values` 子句中的占位符数量与列数量一致，并且**不要在最后加逗号**。 --- ### ✅ 完整修正示例（批量插入）： ```sql insert into ehsdata.p_cer_data (site, cer_one, cer_two, cer_type, cer_name, end_time, status, create_time) values (?, ?, ?, ?, ?, ?, ?, ?), (?, ?, ?, ?, ?, ?, ?, ?), (?, ?, ?, ?, ?, ?, ?, ?) -- 根据实际插入条数继续添加 ; ``` --- ### 🔍 附加建议： 1. **SQL 格式化**： - 使用 SQL 格式化工具或 IDE 插件检查语法。 2. **MyBatis 动态 SQL 批量插入**： 如果你是通过 Java 代码动态生成多条插入语句，建议使用 MyBatis 的 `<foreach>` 实现批量插入，例如： ```xml <insert id="batchInsert"> INSERT INTO ehsdata.p_cer_data (site, cer_one, cer_two, cer_type, cer_name, end_time, status, create_time) VALUES <foreach collection="list" item="item" separator=","> (#{item.site}, #{item.cerOne}, #{item.cerTwo}, #{item.cerType}, #{item.cerName}, #{item.endTime}, #{item.status}, #{item.createTime}) </foreach> </insert> ``` 这样可以避免手动拼接 SQL 出现语法错误。 --- ### ✅ 总结： - 报错原因：SQL 插入语句中每个 `values` 子句最后多了一个逗号。 - 解决方法：删除每个 `values (?, ?, ...),` 中最后的多余逗号。 - 建议：使用 MyBatis 的 `<foreach>` 实现安全的批量插入。 ---
