在ServletContext中定义名为'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，现在我收到此错误。备份早期版本（重新加载到eclipse）的副本也会出现相同的错误。这也很早就行了。

的pom.xml

InjectionFactory

Answer 1

我建议使用新的＆＃39;材料清单＆＃39; Spring 4+的POM功能。这应该可以自动解决任何冲突 - 即使是在第三方jar中，它们具有Spring的传递依赖性。

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

<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>
