我是 Spring 的新手，我想使用 Velocity 对其进行设置。因此，我使用 Spring 工具套件扩展在 Eclipse Kepler 中创建了一个新的 Spring 项目，一个新的 Spring MVC 项目。然后我将 org.apache.velocity 添加到版本为 1.7 的新 Spring 项目中。之后，根据 http://docs.spring.io/spring/docs/3.2.x/javadoc-api/org/springframework/web/servlet/view/velocity/VelocityConfigurer.html，我将以下行添加到我的 servlet-context.xml
<beans:bean id="velocityConfig"
class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
<beans:property name="resourceLoaderPath" value="/WEB-INF/views/" />
</beans:bean>
<!-- View resolvers can also be configured with ResourceBundles or XML files.
If you need different view resolving based on Locale, you have to use the
resource bundle resolver. -->
<beans:bean id="viewResolver"
class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">
<beans:property name="cache" value="true" />
<beans:property name="prefix" value="" />
<beans:property name="suffix" value=".jsp" />
</beans:bean>
然后一切都很好。但是，如果我将 pom.xml 中的 Springframework 版本从 3.1.1.RELEASE 更改为 3.2.4.RELEASE，我会在 Eclipse 中看到以下错误:
No setter found for property 'resourceLoaderPath' in class 'org.springframework.web.servlet.view.velocity.VelocityConfigurer'
我什至用 Ubuntu 设置了一个新的虚拟机来测试它——我到处都遇到同样的错误。您还需要我提供更多文件吗？
在我看来，mvn dependency:tree 的输出看起来并不可疑，对吗？

我想将html转换为纯文本。不过，我不想只删除标签，我想智能地保留尽可能多的格式。为插入换行符标签，检测段落并格式化它们等。输入非常简单，通常是格式良好的html(不是整个文档，只是一堆内容，通常没有anchor或图像)。我可以将几个正则表达式放在一起，让我达到80%，但我认为可能有一些现有的解决方案更智能。 最佳答案 首先，不要尝试为此使用正则表达式。很有可能你会想出一个脆弱/脆弱的解决方案，它会随着HTML的变化而崩溃，或者很难管理和维护。您可以使用Nokogiri快速解析HTML并提取文本:require'nokogiri'h
