测试数据库类型[H2]的驱动程序在类路径中不可用

Question

我正在尝试运行它Spring security web application,但是当部署web-app时,我得到以下异常:

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

虽然我已经在pom.xml中添加了以下内容

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

所以这个jar也可以在classpath中使用,但仍然可以获得异常.

有人能说出我做错了什么吗？

Answer 1

这里是一个曾在我的情况下,我做了以下的变化解决方案pom.xml的文件我要补充<scope>与h2依赖

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

此作用域用于限制依赖项的传递性,还用于影响用于各种构建任务的类路径.

运行范围

此范围表示编译不需要依赖项,但是用于执行.它位于运行时和测试类路径中,但不是编译类路径.
