驱动程序测试数据库类型[H]是不是在类路径

Question

我试图运行的Spring security web application，但是当web应用程序的部署我得到异常下面：已经

o.s.b.f.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/baeldung/spring/TestDbConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean]: Factory method 'entityManagerFactory' threw exception; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'dataSource' defined in class path resource [org/baeldung/spring/TestDbConfig.class]: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [javax.sql.DataSource]: Factory method 'dataSource' threw exception; nested exception is java.lang.IllegalStateException: Driver for test database type [H2] is not available in the classpath

虽然我在pom.xml中添加如下代码

 <dependency> 
      <groupId>com.h2database</groupId> 
      <artifactId>h2</artifactId> 
      <version>1.4.192</version> 
     </dependency> 

所以这个jar也可以在类路径中使用，但仍然会出现以上异常。

有人可以告诉我做错了什么吗？

Answer 1

这里是我的情况下工作的解决方案，我提出以下的pom.xml文件的变化，我要补充<scope>与h2依赖

<dependency> 
    <groupId>com.h2database</groupId> 
    <artifactId>h2</artifactId> 
    <version>1.4.192</version> 
    <scope>runtime</scope> 
</dependency> 

此范围用于限制依赖的传递性，和也可以使用 来影响用于各种构建任务的类路径。

运行范围

此范围表明依赖不需要 编译，但执行。它在运行时和测试 类路径中，但不是编译类路径。
