java - Spring 和 JPA : error while running JUnit test

Question

当我运行我的简单 Junit 测试来测试 Jpa/Dao 配置时，我收到以下错误:

我的应用上下文配置如下:

知道我做错了什么吗？

Answer 1

spring-jdbc.jar 的版本似乎很旧:

<dependency>
    <groupId>springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>1.2.6</version>
</dependency>

使用最新的，DataSourceLookup在 2.0 中引入:

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>3.1.0.RELEASE</version>
</dependency>
