分布式架构Dubbo与Zookeeper基于SSM框架的整合

项目说明：

(避免并发问题(1000并发一个Tomcat500并发)&Tomcat 集群(session问题，配置广播信息)&配置Session(Tomcat的Session复制占用带宽，网络风暴)&多集群(tomcat集群5个作用)&受限制的复制带宽(10000并发)&警惕网络风暴&分布式消息跟踪系统设计(系统与系统之间通信协作，集群一套代码部署多份，分布式一个系统拆分多个子系统，团队隔离不干扰，系统扩展方便)&缓存模式&SOAP 简介&(查询商品一样的服务，代码没办法复用)&WebService& RPC服务框架：Dubbo&(服务使用Dubbo中间件进行管理调用服务)&ActiveMQ ＆ JMS(系统之间解耦))

项目框架：

SSM框架的搭建说明

(pom.xml配置(Parent跳过骨架，需不要继承其他)&Manager(统一定义版本号，propereties，dependencyManagement依赖管理管理版本号，不会依赖jar包，只是统一定义版本号)&添加jacksonJSON解析处理类库并运行(spring必须要依赖jackson)&创建buildxml 文件(指定字符集与Java编译插件，tomcat的插件)&)

(构建WAR文件(创建聚合工厂下面再创建模块，选择pom，也要继承父工程,DAO选择模块打包方式jar包)&依赖(项目之间的依赖)Tbmcat Admin webapp&解决中文乱码&MyBatis逆向工程(Dao依赖pojo，打包方式Jar包，添加MyBatis依赖)&编写Service层处理逻辑(调用服务通过接口调用，打包方式为jar，依赖pojo，service聚合工程是war包要把jar包聚合进来，war包要有web目录工程，服务层要用到spring容器)&Web Service(src/main/webapp相当于webroot根目录需要有一个WEB-INF/web.xml)&web.xml文件(乱码过滤器只有表现层post提交才需要，)&)

taotao-manager做为聚合项目要进行统一管理

(简单配置Spring(web要独立运行，Maven工程，打包war)&创建web.xml文件(web项目可独立部署))

(启动Web应用程序&列出已经部署的Web应用程序&配置Web应用服务器Tomcat(Tomcat插件是Maven插件不要本地安装Tomcat，从公网下载tomcat的jar包放在仓库，也是Java开发直接运行，tomcat插件有个path/ 启动工程的工程名，不需要工程名) &port：查看服务容器端口状态(不配port默认8080)&Clean生命周期()&通过M2Release 插件管理Maven 版本发布&修改启动端口&编译打包运行&启动应用(Maven build clean tomcat7:run )&打包和运行(Update project刷新pom文件之间的依赖关系，Maven install)&的＜welcome＞简单标签(启动访问就能看到，))

(聚合(所有war包都会把jar包加入进去，有个聚合工厂，有任何修改不需要安装，运行聚合工程manager，Maven build )&Clean生命周期(把之前编译的目标文件删除之后，再重新编译一遍)&)

(在Eclipse中创建Library库(打成jar包，访问jar包里的配置文件，在最终运行的war包中service下的lib下的配置文件中，都是classpath)&创建MyBatis映射的相关文件(main/resources/)&配置applicationContext．xml文件(mybatis与spring的整合，配置数据库连接池，SqlSessionFactory，Mapper映射文件的包扫描器，加载配置文件context-property-placeholderlocation=”classpath:propertiees/db.properties”后面不能有空格)&MapperScannerConfigurer(包扫描器，加载全局的配置文件必须要有，basePackage)&Spring整合MyBatis(sqlSessionFactory dataSource name=”configuration” value=”classpath:mybatis/sqlMapConfig.xml”)&sqlSessionFactory创建&)

(创建Service对象(扫描所有带service注解的类放在容器中，context:component-scan base-package=””子包也能扫描到)&启用自动配置注解&hibernatetransactionmanager的实现(事务管理器DataSourceTransactionManager指定数据源)&数据库通知(txAdvice通知，以save等单词开头会开启事务，read-only不需要开启事务)&应用切面(advisor

Advice-ref=”txAdvice” pointcut=”execution(* com.taotao.service.*.*(..))”)&)

(初始化pring 应用(web.xml )&Spring容器&ContextLoaderListener(初始化srpigng容器，加载context-param contextConfigLocation param-value classpath:spring/application-*.xml)&DispatcherServlet(前端控制器，)&DispatcherServlet的初始化&父子容器(spring父容器ContextLoaderListener，配置前端控制器之后子容器DispatcherServlete初始化，子容器可以访问父容器，父容器不可以访问子容器，父容器Dao或者Service，子容器放入Controller，子容器可以注入Dao)&)

(Spring集成Dubbo&远程过程调用协议(关系越来越多，调用越来越乱，需要服务治理工具Dubbo，统一注册管理工具)&)

(基于Dubbo实现分布式调用跟踪系统方案(每次调用服务去注册中心调用服务，provider与consumer之间进行通信)&基于ZooKeeper实现分布式配置管理平台方案(zookeeper作为注册中心，集群管理工具)&ooKeeper的下载与集群安装&)

(安装Zookeeper(rm -rf * 客户端连接zookeeper默认端口2181)&重要的Linux基础命令&SSH和文件传输（scp和sftp）(SecureCRT,)&创建和修改配置文件(mkdir data )&vim程序编辑器(cd ll bin ll conf vim zoo.cfg pwd dataDir) &打包命令：tar(tar zxf zookeeper-3.tar.gz) &XFS文件系统的备份与还原&复制、删除与移动：cp、rm、mv&相对路径与绝对路径(mv zoo.cfg)& start：启动服务容器( ./zkServer.sh start ./status)& stop：停止服务容器(./zkServer.sh stop)&)

(Dubbo配置(发布服务dubbo:service interface ref直接引入容器中的bean对象启动容器自动发布服务，引入Dubbo相关的Jar包，发布Dubbo服务要配置注册中心的application的name与注册中心的地址)& Dubbo Bean的加载(调用服务dubbo:reference id来引用服务)&long与double的操作不是原子的&注解@Autowired()&排除依赖&基于schema设计解析&基于XML配置实现&服务暴露的实现原理&本地服务的暴露机制(service模块添加对interface模块的引用)&排除依赖&(要把Duubo引入的低版本的Netty与Spring排除))

(单注册中心消费原理&Dubbo远程调用&Dubbo调用介绍&@ResponseBody转换为JSON的秘密(响应Json数据)&Feign声明式调用　406(如果没有把jackSon的jar包加入会发生406的错误)&使用jackson在服务端将JSON字符串转换成各种Java数据类型&)

(Mapper映射文件(解决mapper映射文件不发布的问题，没有把xml文件发布到target目录下，要在build中配置directory路径)&)

(复制、删除与移动：cp、rm、mv &微服务监控中心(Dubbo的监控中心是一个war包，发布到tomcat中启动cp dubbo-admin.war tomcat/webapps/dubbo-admin.war bin/startup.sh tail -f logs/catalina.log。推荐把监控中心与注册中心(zookeeper)安装在一台服务器上，监控连接zookeeper来判断调用关系，如果不再同一台机器，需要修改dubbo-adim中WEB-INF/下的dubbo.properties配置文件，修改zookeeper的地址即可)&)

(静态资源映射(mvc:resources location=”/css/” mapping=”/css/**”是url路径下的多级目录)&点缀 EasyGrid&)

(MyBatis插件机制(xml文件中配置分页插件，plugin在执行查询之前拦截sql语句拼接sql语句，再配置上数据库的方言dialect)&使用MyBatis分页插件pagehelper(startPage两个参数，第几页，每页大小)&从getBean()方法开始&)

(RequestMapping注解(形参名称与参数一致即可映射过来)&)

(源码分析(Debugger需要在configuration中添加源代码/source 添加对应的Java project模块，要注意是否为Spring的@service注解，Dubbo也有service注解)&)

(SVN配置仓库(创建SVN仓库)&应用基于主干的开发实践(代码放在trunk主干里，在分支里开发完毕，之后要把修改内容合并到主干里，发布之后就要建立一个分支，主干向前开发，有bug在分支里修改，保证主干内容是最新的)&基于特性分支的开发(tag标签，根据书签去取哪一个版本)&配置SVN资源库(Copy URL，)&将项目发布到服务器(share Project，创建新的SVN资源库，使用项目名称，之后再trunk下新建一个项目，看到本地与服务端的差异，+要上传的，同步刷新区别，不要把setting project上传服务端添加svn igonore，WINDOW perference SVN Ingore resources Add .settings .project .classPath)&提交（Commit）修改(提交之前先更新，之后提交，提交聚合工厂，不要提交模块会重复提交，要忽略target再提交，先提交pom文件夹，提交之后刷新一下，底下的子文件dao，interface，pojo，service隐藏逻辑删除引用，引用存在的Maven工程)&同步（Update）本地文件()&)

(使用Eclipse作为SVN客户端(SVN资源库研究，废弃位置，千万不能在SVN资源库删除代码，Import 从SVN检出项目，可以多选检出，不要后退)&converter (转为Maven工程，先转parent，再转common，最后Configure-Convert to Maven Project))
