Spring中事务的配置学习: 1.心法 Spring配置文件中关于事务配置总是由三个组成部分,分别是DataSource.TransactionManager和代理机制这三部分,无论哪种配置方式,一般变化的只是代理机制这部分. DataSource.TransactionManager这两部分只是会根据数据访问方式有所变化. 比如使用Hibernate进行数据访问时,DataSource实际为SessionFactory,TransactionManager的实现为HibernateTrans…

Solr4.8.0源码分析(6)之非排序查询 上篇文章简单介绍了Solr的查询流程,本文开始将详细介绍下查询的细节.查询主要分为排序查询和非排序查询,由于两者走的是两个分支,所以本文先介绍下非排序的查询. 查询的流程主要在SolrIndexSearch.getDocListC(QueryResult qr, QueryCommand cmd),顾名思义该函数对queryResultCache进行处理,并根据查询条件选择进入排序查询还是非排序查询. 1  /** 2 * getDocList ve…

Solr4.8.0源码分析(5)之查询流程分析总述 前面已经写到,solr查询是通过http发送命令,solr servlet接受并进行处理.所以solr的查询流程从SolrDispatchsFilter的dofilter开始.dofilter包含了对http的各个请求的操作.Solr的查询方式有很多,比如q,fq等,本章只关注select和q.页面下发的查询请求如下:http://localhost:8080/solr/test/select?q=code%3A%E8%BE%BD*+AND+l…

1. Spring事务管理简介 (1)Spring为多种不同类型的事务管理机制提供统一编程模型,这些事务管理模型包括JTA.JDBC.Hibernate.JPA和JDO. (2)Spring支持声明式事务管理(使用XML文档配置(或者Annotation)结合AOP实现的事务管理). (3)为代码嵌入式(programmatic)的事务管理提供API接口,与复杂的JTA接口相比要简单的多. (4)能够与Spring的数据抽象访问完美结合. 2． Spring事务管理的优点 一般认为,JavaEE…

在使用scss和less开发的时候,遇到过一件很有趣的事,因为网站需要支持响应式,就开了一个响应式样式框架,简单的几百行scss代码,居然生成了近100KB的css代码,因此决定重构这个样式库.而重构后的项目总是出现各种各样的问题,尤其在响应式方面,可能在一种分比率下页面显示正常,而在另一种分辨率下页面却变得面目全非,几次调整都有遗漏的地方,忙得测试人员(其实就是我自己了)不可开交.最后总结为样式开发也是需要做自动化回归测试的,尤其是开发具有响应式功能的复杂样式库的时候,自动化测试尤其重要. 如…

JUnit与JMock学习 测试驱动编程和持续集成部署应该说是现在软件开发者的必备武器,不过跟其他很多好东西一样,在我们公司的推广总要慢上一拍,毕竟老板看的是你能够把功能实现好让客户满意,所以能不折腾就不折腾.但不管用不用,先学下单元测试技术吧. JUnit单元测试 用JUnit写单元测试,首先是定义一个单元测试类:然后在类中定义测试方法,使用@Test标签即可. 重要标签 ANNOTATION DESCRIPTION @Test 定义test case @Test(expected = Exc…
