- html - 出于某种原因,IE8 对我的 Sass 文件中继承的 html5 CSS 不友好?
- JMeter 在响应断言中使用 span 标签的问题
- html - 在 :hover and :active? 上具有不同效果的 CSS 动画
- html - 相对于居中的 html 内容固定的 CSS 重复背景?
我正在使用 Maven 构建一个应用程序。我在本地MySql中有一个数据库,当它仍在Eclipse环境中时,一切似乎都正常。应用程序和数据库之间的连接功能齐全,无需担心。在 Maven 中,我设置了目标“package”,到目前为止没有出现任何问题,但是当应用程序想要进行 SELECT ALL 查询时,它会遇到以下错误:

有人知道为什么我会收到此异常吗?
最佳答案
终于可以回答我的问题了。问题其实很明显,就是因为经验不足。在 POM 文件中,我需要向 list 添加一个类路径,我是这样做的:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.4</version>
<configuration>
<archive>
<manifest>
<mainClass>main.java.festival.ArtFestivals</mainClass>
<addClasspath>true</addClasspath>
<classpathPrefix>lib/</classpathPrefix>
</manifest>
</archive>
</configuration>
</plugin>
并且成功了。
