我正在 NetBeans 7.2.1 中开发一个项目。我已经下载了 Spring 的最新版本 3.2.1和 Apache Tiles 的 newset版本 3.0.1，因为我想用比 JSP 包含的更好的东西来模板化我的视图。

我有一个定义了以下bean的spring servlet配置文件：

<bean id="tilesConfigurer" class="org.springframework.web.servlet.view.tiles3.TilesConfigurer">
    <property name="definitions">
        <list>
            <value>/WEB-INF/tiles-defs.xml</value>
        </list>
    </property>
</bean>

在本Libraries节中，我包括了整个 spring-3.2.1（一切可能）和 4 个来自瓷砖的 jar 文件：

  • 瓷砖-api-3.0.1.jar
  • 瓷砖核心3.0.1.jar
  • 瓷砖-jsp-3.0.1.jar
  • 瓷砖请求-api-3.0.1.jar

spring-webmvc-3.2.1jar 包括在那里拥有类的org.springframework.web.servlet.view.tiles3包SpringWildcardServletTilesApplicationContext。

Tomcat 设法部署了这个项目，但它不断抛出以下异常，指的是 NetBeans 项目库中包含的类：

有什么问题，我应该看什么？

NoClassDefFoundError 表示在编译时找到了类，但在运行时没有找到，所以它是由 JRE 抛出的。

在您的情况下，问题是关于tilesConfigurer bean 而不是SpringWildcardServletTilesApplicationContext类。确保包含 bean 的所有超类和这些超类的依赖 jar。

您也可以使用SystemClassLoader检查类路径。

关于tilesConfigurer。
