将Oauth2实现到我的项目中

我是Spring框架的新手，因此发生了一个异常，例如ClassNotFoundException，尽管所有兼容的类存在于正确的包下。可以在github上看到来源（maven项目）谢谢

错误始于：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping#0': Invocation of init method failed; nested exception is org.springframework.beans.factory.CannotLoadBeanClassException: Cannot find class [com.trafficalarm.rest.security.HierarchicalJsr250Voter] for bean with name 'roleVoter' defined in class path resource [spring/security/security-configuration.xml]; nested exception is java.lang.ClassNotFoundException: com.trafficalarm.rest.security.HierarchicalJsr250Voter

确保web.xml正确初始化spring上下文： [UPDATE]

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>
        classpath:app-config.xml
    </param-value>
</context-param>

必须是直接的孩子。然后，在您的app-config中，您可以使用

扫描所有组件

<context:component-scan base-package="your.component.package.here"/>

然后导入所有弹簧配置文件

<import resource="classpath:your-resource.xml"/>

我还注意到PropertiesPlaceholderConfigurer bean没有正确配置，所以我不得不在我的一个spring配置文件上执行类似的操作，因为spring没有找到文件属性，所以它到处抛出异常：

<bean id="propertyPlaceholderConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location"  value="WEB-INF/application.properties"/>`</bean>`

有些课程你实际上并不需要，但这取决于你。希望你能用这些提示搞清楚。

此致

关于异常的基本问题是构建路径问题。当我将security-configuration.xml文件内容移动到business-config.xml时，ide警告我有关构建路径问题的信息。所以我检查了项目的构建路径，maven dependecies似乎未经检查。我以前更改了JDK的版本，所以我认为这导致了未经检查的情况。不幸的是，注意了一段时间......
