java.lang.NoSuchMethodError: org.springframework.beans.factory.xml.XmlReaderContext.getResourceLoader()Lorg/springframework/core/io/ResourceLoader

I am working on a Spring application on Tomcat7, JDK1.7, Maven and other components. Recently, I made a major change to the application, requiring switching over to Spring 3. After the change, I'm seeing the below exception on deploying to dev server. The application runs flawlessly on my local system though.

需要帮助在Spring/Maven上配置MongoDB

当我在Spring中编写代码时,我总是使用注释,并且在基于xml的配置时总是卡住.现在,我遇到了一个可能非常简单的问题.如果你能帮我解决这个问题,我将不胜感激.

创建新的spring注释

我正在Spring中开发一个应用程序,它在控制器中有许多方法,并使用@RequestMapping映射到各种URL.

其中一些方法(以及url)可供某些用户角色访问,而不是其他用户角色.我是否可以创建注释并注释这些方法,以便只有特权用户才能访问正确的方法,而不能访问其他方法？

提前致谢.

如何限制/控制 Apache Jmeter 中的采样率？

好的，我可以控制 Apache JMeter 中的以下参数：

  1. 线程数（用户）
  2. 加速时间（以秒为单位）

如何测试变化的采样率而不变化的用户添加率？即使是固定的采样率也可以。

提前致谢 ：）

Tomcat无法在Amazon EC2,Redhat实例上运行
