小编mat*_*tis的帖子

我一遍又一遍地得到这个错误:

10:37:21,270 ERROR DispatcherServlet:466 - 上下文初始化失败org.springframework.beans.factory.parsing.BeanDefinitionParsingException:配置问题:无法找到XML架构命名空间的Spring NamespaceHandler [http://activemq.apache.org/schema/核心]违规资源:ServletContext资源[/WEB-INF/mvc-dispatcher-servlet.xml]

我尝试了很多pom.xml和spring配置,但到目前为止它们都没有.

这是我的pom.xml中的依赖项:

我有这样一段代码:

private String getUsername(PersonalAccount account) {
    User usr = (User)account?.usr
    String name = usr?.getName()
    return name
}

在PersonalAccount类中我们有字段:

SimpleUser usr

用户扩展了SimpleUser

这意味着什么:？在这两行？

User usr = (User)account?.usr
    String name = usr?.getName()

我正在尝试将messageSourcebean 注入到我的组件类中。

这是bean xml的一部分：

<context:annotation-config />

<context:component-scan base-package="com.mattis.test"/>

<bean id="localeResolver"
      class="org.springframework.web.servlet.i18n.SessionLocaleResolver">
    <property name="defaultLocale" value="en" />
</bean>

<bean id="messageSource"
      class="org.springframework.context.support.ResourceBundleMessageSource">
      <property name="basename" value="messages" />
</bean>

在我的组件中，我得到了这个：

@Component
public class TestClass {

@Autowired
private MessageSource messageSource;

<-- more code goes here -->
}

总是在我实例化TestClass时，messageSource为null。我尝试了更多的bean xml和类配置，但是它们都不起作用。
