Spring

求关于这句话的解释~~
《精通Spring2.x》第八章中的一句话:Spring面向DAO制定了一个通用的异常体系,屏蔽具体持久化技术的异常,是业务层和具体的持久化技术达到解耦。

  本人不知道这里怎么就实现解耦了。。。

谢谢!

更新方法

at com.lyx.test.TestDemo.main(TestDemo.java:28)
[/code]

原理:
按照 要求 异常应该是由底层往上层逐级抛出的。底层不处理异常 , 让在最终的层处理异常。持久层的异常有业务层处理 。
这样的话 业务层就与持久层的异常产生的耦合。
spring 的方案是在持久层层时 处理处理异常 , 处理的方式 是 在 catch 语句中抛出spring 定义的异常。

看代码:

Spring Security与Spring Session集成实现Session共享的问题

项目使用Spring Boot,Spring Security,已经成功集成Spring Session与redis,现在有两个问题 1.为什么每次访问系统登录页,SpringSession都会在redis里面存一个session呢? 2.Spring Security中的Session管理怎么与SpringSession结合到一起?SpringSecurity的Session管理貌似是存在内存的,SpringSession放在redis,二者联系不到。比如清空了Redis,那项目的内存中还是存在Session,怎么实现关联... 菜鸟只能想到实现SessionRegistry接口了... 有没有大神或者做过相关的大神指教一下,讨论一下(*^__^*)

eclipse安装spring插件没有Spring Bean Definition file

问下这是什么情况,new>Spring Bean Definition file这个选项没有,百度查了2天都没解决这个问题,也没找到原因,有些是说在eclipse 里面的Spring选项设置,然而我的根本就没有Spring这个选项。然后看到别人安装好了 插件貌似就能直接创建了,但是我这边搞了几次都没找到。 我的eclipse是直接新解压的,然后在安装对应的spring tool suite插件,然后其它任何 操作都没做!

spring security+spring session+redis反序列化问题

我在spring security+spring session使用redis,序列化方式是GenericJackson2JsonRedisSerializer,但是spring security在认证成功之后会保存一个SecurityContextImpl到redis,这个类是有无参构造的,但是这个类下面有一个UsernamePasswordAuthenticationToken类没有无参构造,造成反序列化失败,认证就失败了,没有找到解决办法,总不能重新打包spring的jar包,也没办法自定义反序列化方式,改成jdk序列化太占空间,又不想改成fastjson,bug太多,不想一个项目中依赖两个json工具,前辈们有什么办法吗??

推荐一本Spring的书

这个题目我定50分,所以有一些要求 本人学过Spring的ioc、aop,有一定基础,现在需要一本详细介绍Spring全部内容的书,并且可以作为工具书 1.推荐的人要真的读过这本书(电子也算) 2.卓越上可以买到中文版 3.花起码30字描述一下书的内容、翻译质量、内容深度、阅读体验、纸张品质 4.粘贴来的不算数 [b]问题补充:[/b] 对楼下的答案有点失望 我今天去书店看了大部分人推荐的spring in actino 字体非常小 看起来简直是噩梦 相比较看了两本图灵的书 一个是深入Spring MVC 一个是企业Spring 感觉的书的排版质量好得多 但是不太全面 无法做工具书 里面都提到pro Spring 但是我却没有找到这本书

weblogic 中用Spring Security出现问题

在Tomcat时使用spring security正常。但部署到weblogic 中用Spring Security就出现问题了。 当用户登录时跳向了Spring配置的类。而没有跳向Spring Security中配置的登录类。 还有我对Spring Security进行了扩展,有些启动时用的bean也需要去Spring中找,需要操作数据库, 这时候Spring还没有启动,bean应该是找不到的,所以Spring Security会报错。 现在是怎样能让Spring先启动,Spring Security后启动

PropertyPlaceholderConfigurer整合spring cloud config

有一个历史项目,想调整为spring boot项目,并使用spring cloud各组件,原项目内大量的spring xml配置文件,不想费力气变更为配置类,通过@ImportResource来处理, 但是原spring xml类中有大量使用${}的地方, 新的模式下,是通过spring cloud config 统一来管理配置文件的,原有通过PropertyPlaceholderConfigurer来管理xml文件中${},就失效了。 还请各位帮助,怎样能保持原有xml文件,又能使用spring cloud config 来管理原有xml文件中的${}这些变量 万分感谢

Spring boot Security 多种登录方式混合?

我现在有一个这样的需求,使用spring boot 开发一个微信小程序。微信小程序使用spring boot 做 服务器后台,通过rest_api交互,用户小程序登录后可以利用jwt 来保护rest api 和一此网站资源。 另外也使用相同的spring boot 程序开发一个让管理员使用的后台,如管理微信用户在小程序中下的订单信息。后台管理员通过浏览器访问,使用form认证。 总结:如休让一个spring boot 程序 即可以rest api 的方法认证登录,也可以利用表单方式认证登录

spring boot整合spring security如何自定义登陆页面

请问spring boot整合spring security如何自定义登陆页面, /** * Created by song on 2016/5/28. * 设置 /login 转向 login.html页面 */ @Configuration public class SpringMvcConfig extends WebMvcConfigurerAdapter{ @Override public void addViewControllers(ViewControllerRegistry registry){ registry.addViewController("/login").setViewName("login"); } } 没有定位到这个login.html页面,是不是需要在启动类或者是spring security配置类里面配置一下呢,求大神解惑,感激不尽 ![图片说明](https://img-ask.csdn.net/upload/201605/28/1464367522_822821.png) ![图片说明](https://img-ask.csdn.net/upload/201605/28/1464367535_886911.png)

spring的核心作用到底是什么

我没有使用过sun官方的那堆重量级j2ee架构,知道j2ee是从ssh开始,用了这么长回见,包括研究源码后,我赫然发现对于spring,我往往只用到了它的两个功能,依赖注入和事务管理,可是依赖注入的原理我都搞明白,手动注入又有啥不可以,虽然说手动注入有耦合问题,但是spring的注入并不是很灵活,尤其是需要临时生成某个属性参数的场合。不用spring进行事务管理,很多数据库中间件自己的模板管理的也不错,那spring还有什么存在的意义。spring这东西当初到底为了啥被发明出来的

昨天早上通过远程的方式 review 了两名新来同事的代码,大部分代码都写得很漂亮,严谨的同时注释也很到位,这令我非常满意。但当我看到他们当中有一个人写的 switch 语句时,还是忍不住破口大骂:“我擦,小王,你丫写的 switch 语句也太老土了吧!” 来看看小王写的代码吧,看完不要骂我装逼啊。 private static String createPlayer(PlayerTypes p...

上班一个月,后悔当初着急入职的选择了

最近有个老铁,告诉我说,上班一个月,后悔当初着急入职现在公司了。他之前在美图做手机研发,今年美图那边今年也有一波组织优化调整,他是其中一个,在协商离职后,当时捉急找工作上班,因为有房贷供着,不能没有收入来源。所以匆忙选了一家公司,实际上是一个大型外包公司,主要派遣给其他手机厂商做外包项目。**当时承诺待遇还不错,所以就立马入职去上班了。但是后面入职后,发现薪酬待遇这块并不是HR所说那样,那个HR自...

女程序员,为什么比男程序员少???

昨天看到一档综艺节目,讨论了两个话题:(1)中国学生的数学成绩,平均下来看,会比国外好?为什么?(2)男生的数学成绩,平均下来看,会比女生好?为什么?同时,我又联想到了一个技术圈经常讨...

为什么本科以上学历的人只占中国人口的5%,但感觉遍地都是大学生?

中国大学生占总人口不到5% 2017年,中国整体的本科率仅有5.9%;如果算上研究生,这一比例可以进一步上升到6.5% 为什么在国家统计局推出的这份年鉴中,学历的最高一阶就是到研究生,而没有进一步再统计博士生的数量的。 原因其实并不难理解,相比全国和各省整体人口体量,博士生的占比非常之低,属于绝对意义上的小概率样本。 这一点,我们从上表中的各省研究生占比情况也可以看出端倪。除北京、天津、上海三...

副业收入是我做程序媛的3倍,工作外的B面人生是怎样的?

提到“程序员”,多数人脑海里首先想到的大约是:为人木讷、薪水超高、工作枯燥…… 然而,当离开工作岗位,撕去层层标签,脱下“程序员”这身外套,有的人生动又有趣,马上展现出了完全不同的A/B面人生! 不论是简单的爱好,还是正经的副业,他们都干得同样出色。偶尔,还能和程序员的特质结合,产生奇妙的“化学反应”。 @Charlotte:平日素颜示人,周末美妆博主 大家都以为程序媛也个个不修边幅,但我们也许...

外包程序员的幸福生活

今天给你们讲述一个外包程序员的幸福生活。男主是Z哥,不是在外包公司上班的那种,是一名自由职业者,接外包项目自己干。接下来讲的都是真人真事。 先给大家介绍一下男主,Z哥,老程序员,是我十多年前的老同事,技术大牛,当过CTO,也创过业。因为我俩都爱好喝酒、踢球,再加上住的距离不算远,所以一直也断断续续的联系着,我对Z哥的状况也有大概了解。 Z哥几年前创业失败,后来他开始干起了外包,利用自己的技术能...

离职半年了,老东家又发 offer,回不回?

有小伙伴问松哥这个问题,他在上海某公司,在离职了几个月后,前公司的领导联系到他,希望他能够返聘回去,他很纠结要不要回去? 俗话说好马不吃回头草,但是这个小伙伴既然感到纠结了,我觉得至少说明了两个问题:1.曾经的公司还不错;2.现在的日子也不是很如意。否则应该就不会纠结了。 老实说,松哥之前也有过类似的经历,今天就来和小伙伴们聊聊回头草到底吃不吃。 首先一个基本观点,就是离职了也没必要和老东家弄的苦...

记录下入职中软一个月(外包华为)

无代码时代来临,程序员如何保住饭碗?

编程语言层出不穷,从最初的机器语言到如今2500种以上的高级语言,程序员们大呼“学到头秃”。程序员一边面临编程语言不断推陈出新,一边面临由于许多代码已存在,程序员编写新应用程序时存在重复“搬砖”的现象。 无代码/低代码编程应运而生。无代码/低代码是一种创建应用的方法,它可以让开发者使用最少的编码知识来快速开发应用程序。开发者通过图形界面中,可视化建模来组装和配置应用程序。这样一来,开发者直...

Java岗开发3年,公司临时抽查算法,离职后这几题我记一辈子

前几天我们公司做了一件蠢事,非常非常愚蠢的事情。我原以为从学校出来之后,除了找工作有测试外,不会有任何与考试有关的事儿。 但是,天有不测风云,公司技术总监、人事总监两位大佬突然降临到我们事业线,叫上我老大,给我们组织了一场别开生面的“考试”。 那是一个风和日丽的下午,我翘着二郎腿,左手端着一杯卡布奇诺,右手抓着我的罗技鼠标,滚动着轮轴,穿梭在头条热点之间。 “淡黄的长裙~蓬松的头发...
