Spring OAuth2 实现与 InMemoryTokenStore bean 创建问题

Question

我尝试使用此 blog

在我的项目中实施 Oauth2

我是 Spring 框架的新手，所以发生了诸如 ClassNotFoundException 之类的异常，尽管所有兼容的类都存在于正确的包下。源码（maven项目）可以在github上看到谢谢

错误开始于：

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

Answer 1

确保您 web.xml 正确初始化了 spring 上下文： [更新]

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

必须是直系子代。然后，在您的应用程序配置中，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 spring 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 配置文件上做这样的事情，它到处都在抛出异常，因为 spring 没有找到文件属性：

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

有些类您实际上并不需要，但这取决于您。希望你能通过这些提示弄明白。

此致

异常的本质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 警告我构建路径问题。所以我检查了项目的构建路径，maven dependecies 似乎没有被选中。我之前更改了 JDK 的版本，所以我认为这导致了未检查的情况。不幸的是，注意到花了一段时间...
