关于ssm中多数据源链接的的问题: 最近做项目碰到一个难题，要实现的功能是在一个项目中采用多数据源的配置，然后就是需要在连接一个数据源的情况下再去链接另外一条数据源也就是说最开始的数据源链接是不能中断的。需要在链接第一条数据源的前提下，关联查询另外一个数据源下的表. Baidu了很多都没有找到想要的解决方案，想听一下大家的建议！！！

关于ssm框架多数据源事物管理，大神来看一下: 当多个数据源配置的事物管理都包含了service层的某方法时，是否是几个数据源共同管理这方法?其中只要有一个数据源加载失败就不能进入该方法。

客户端调用服务端报 null？: ssm整合cfx 客户端调用服务端操作数据库的方法报null public static void main(String[] args) throws Exception { JaxWsDynamicClientFactory dcf = JaxWsDynamicClientFactory.newInstance(); Client client = dcf.createClient("http://localhost:8081/ssm_2/webservice/HelloWorld?wsdl"); Object[] objects=client.invoke("all"); //调用web Service//输出调用结果 System.out.println(objects.length+"---"+objects[0].toString()); } 这是客户端调用 @Service @WebService(endpointInterface="com.jksd.service.UserServices",serviceName="UserServices",targetNamespace="http://service.jksd.com/") public class ServicesImpi implements UserServices { @Autowired private static UserDao user; @Override public List<Permissionlist> all() { // TODO Auto-generated method stub return user.all(); } @Override public String sys(String str) { // TODO Auto-generated method stub return "666"; } } 报 user.all（）为 null ``` ``` Caused by: java.lang.NullPointerException: null at com.jksd.service.servicesImpi.ServicesImpi.all(ServicesImpi.java:23) ~[classes/:na] 这是报的错 ``` ```

请问下在整合ssm框架时报这个错误该怎么解决？: ## **1.第一页** ![图片说明](https://img-ask.csdn.net/upload/201910/16/1571224722_863231.png) ** ## 2.第二页 ![图片说明](https://img-ask.csdn.net/upload/201910/16/1571224807_118936.png) ## 3.第三页 ![图片说明](https://img-ask.csdn.net/upload/201910/16/1571224865_134839.png) 4.这是application.xml文件的sqlSessionFactory配置区域 ![图片说明](https://img-ask.csdn.net/upload/201910/16/1571224974_334955.png)

Java学习的正确打开方式: 在博主认为，对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结，前三者博主将淋漓尽致地挥毫于这篇博客文章中，至于总结在于个人，实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍，博客次之，这又是一个层次了，这里暂时不提后面再谈。博主将为各位入门java保驾护航，各位只管冲鸭！！！上天是公平的，只要不辜负时间，时间自然不会辜负你。何谓学习？博主所理解的学习，它

程序员必须掌握的核心算法有哪些？: 由于我之前一直强调数据结构以及算法学习的重要性，所以就有一些读者经常问我，数据结构与算法应该要学习到哪个程度呢？，说实话，这个问题我不知道要怎么回答你，主要取决于你想学习到哪些程度，不过针对这个问题，我稍微总结一下我学过的算法知识点，以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的，并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构，当然，我也会整理一些看过

大学四年自学走来，这些私藏的实用工具/学习网站我贡献出来了: 大学四年，看课本是不可能一直看课本的了，对于学习，特别是自学，善于搜索网上的一些资源来辅助，还是非常有必要的，下面我就把这几年私藏的各种资源，网站贡献出来给你们。主要有：电子书搜索、实用工具、在线视频学习网站、非视频学习网站、软件下载、面试/求职必备网站。注意：文中提到的所有资源，文末我都给你整理好了，你们只管拿去，如果觉得不错，转发、分享就是最大的支持了。一、PDF搜索网站推荐对于大部

linux系列之常用运维命令整理笔录: 本博客记录工作中需要的linux运维命令，大学时候开始接触linux，会一些基本操作，可是都没有整理起来，加上是做开发，不做运维，有些命令忘记了，所以现在整理成博客，当然vi，文件操作等就不介绍了，慢慢积累一些其它拓展的命令，博客不定时更新顺便拉下票，我在参加csdn博客之星竞选，欢迎投票支持，每个QQ或者微信每天都可以投5票，扫二维码即可，http://m234140.nofollow.ax.

比特币原理详解: 一、什么是比特币比特币是一种电子货币，是一种基于密码学的货币，在2008年11月1日由中本聪发表比特币白皮书，文中提出了一种去中心化的电子记账系统，我们平时的电子现金是银行来记账，因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述，这一层面介绍的文章很多，本文主要从更深层的技术原理角度进行介绍。二、问题引入假设现有4个人

程序员接私活怎样防止做完了不给钱？: 首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。那么，怎么保证自己的薪酬安全呢？我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发

通俗易懂地给女朋友讲：线程池的内部原理: 餐厅的约会餐盘在灯光的照耀下格外晶莹洁白，女朋友拿起红酒杯轻轻地抿了一小口，对我说：“经常听你说线程池，到底线程池到底是个什么原理？”我楞了一下，心里想女朋友今天是怎么了，怎么突然问出这么专业的问题，但做为一个专业人士在女朋友面前也不能露怯啊，想了一下便说：“我先给你讲讲我前同事老王的故事吧！” 大龄程序员老王老王是一个已经北漂十多年的程序员，岁数大了，加班加不动了，升迁也无望，于是拿着手里
