创建在ServletContext中定义的名称为“ dataSource”的bean时出错

Question

帮我解决这个错误！！！ 该项目运行较早，没有任何错误。 几天后，尝试再次运行它，现在出现此错误。 较早版本的备份副本（重新加载到eclipse中）也给出相同的错误。 早期也很好。

Answer 1

我建议使用Spring 4+的新“物料清单” POM功能。 这应该可以自动解决任何冲突-即使是在对Spring具有传递依赖项的第3方jar中也是如此。

从pom中的所有Spring库中删除<version/>元素，并添加以下依赖项管理部分：

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-framework-bom</artifactId>
            <version>4.0.2.RELEASE</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>
