Question

我确信这是一个简单的配置问题，但我找不到它。当我在STS中运行我的java代码时

Spring Tool Suite 

Version: 3.8.3.RELEASE
Build Id: 201612191457
Platform: Eclipse Mars.2 (4.5.2)

一切顺利。没有错误，没有问题。代码完成了应有的一切。

当我从命令行使用mvn包构建jar然后尝试运行它时，我得到：

    at com.zaxxer.hikari.pool.PoolBase.newPoolEntry(PoolBase.java:201)

我检查了所有我要检查的内容并且不知所措。我觉得这个必须是我错过的地方，但我找不到任何东西。

Answer 1

在JDBC 4.0中添加了isValid方法。

增加依赖性的问题：

    <dependency>
        <groupId>com.ibm.db2</groupId>
        <artifactId>db2jcc</artifactId>
        <version>10.5</version>
        <scope>compile</scope>
    </dependency>

你需要使用：

<dependency>
    <groupId>com.ibm.db2.jcc</groupId>
    <artifactId>db2jcc4</artifactId>
    <version>10.1</version>
</dependency>

在STS中运行的代码没有问题，从命令行运行时崩溃
