Junit测试用例失败：java.lang.IllegalStateException：无法加载ApplicationContext

Question

在从源（svn 存储库）代码构建项目时，（包括 junit 测试用例）junit 通过且没有任何错误。但是，单独运行 junit 时，junit 会失败。我已经添加了所有必需的 jar 文件。 java、jdk路径和环境变量都正确。

以下是我遇到的异常，请帮忙：

您收到 java.lang.NoClassDefFoundError 是因为运行测试时类路径中缺少 org.springframework.beans.jar （其中包含 org.springframework.expression.PropertyAccessor）。

您运行单个测试的方式必须与运行所有测试时的方式不同。
