上一节我们说过Spring对DAO的两个支持分为两个知识点,一个是jdbc模板,另一个是事务管理. 事务是数据库中的概念,但是在一般情况下我们需要将事务提到业务层次,这样能够使得业务具有事务的特性,来管理业务. 例如:在银行的转账系统中,张三转账给李四,需要完成从张三的账户上扣取指定金额并加到李四的账户上,这样一个过程需要具有原子性,即要成功都成功,要失败都失败.转账的过程即两个对账户更新,需要将事务提升到业务层次,使得两个操作具有原子性! 对以上的实现,Spring的API中有两个常用的接口我

最近在myeclipse上创建maven类型的web项目的时候,出现了一个错误. ArtifactTransferException: Failure to transfer org.apache.openejb:javaee-api:jar:5.0-1 from http://100.66.227.204:8081/nexus/content/groups/public/ was cached in the local repository, resolution will not be re

因为maven下载依赖jar包时,特别慢,所以取消了下载过程,再次打开eclipse时,maven的pom.xml文件报错如下: ArtifactTransferException: Failure to transfer xom:xom:jar:1.2.5 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until th

故障:打开“Windows Update”出现红色盾牌图标 点击“检查更新”,出现“Windows Update 当前无法检查更新,因为未运行服务.您可能需要重新启动计算机” 查看“Windows Update”服务,正常 查看“Background Intelligent Transfer Service”服务,正常 解决方法:关闭“Windows Update”窗口,停掉“Windows Update”服务 重命名Windows目录下边的“SoftwareDistribution”文件夹为“

在日常开发中由于业务逻辑较为复杂,常常需要用到UPDATE和CASE...WHEN...THEN...ELSE...END一起做一些复杂的更新.有时候因为对这几个字句理解得不透彻会带来很大的困扰.因此对UPDATE和CASE WHEN结构的特性做进一步的测试. CASE WHEN的两种写法: Type 1: CASE value WHEN [compare-value] THEN result [WHEN [compare-value] THEN result ...] [ELSE result

我在使用Myeclipse碰见这个错误,我没有用伺服,直接连接到maven中心. ArtifactTransferException: Failure to transfer org.apache.hadoop:hadoop-core:jar:1.1.1 from http://repo.maven.apache.org/maven2 was cached in the local repository, resolution will not be reattempted until the

到百度搜了常用的解决方法,就是用命令提示符,但对我的情况不管用,提示“拒绝访问”.后来在08绿软站的一篇文章中找到了解决办法.原文如下(我本人也是用的第四种方法解决的): 试了下面几种解决方法,第四种方法解决了我的问题. 第一种方法无非就是检查windows update等服务是否开启.1.右键计算机——管理,在右侧选择“服务和应用程序”——服务,2.双击打开“Windows Update”服务.3. 点击“常规”选项卡,确保“启动类型”是“自动”或者“手动”.然后点击“服务状态”下面的“启用”
