篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了为啥ssm框架都要有maven管理呢，不用可以嘛，有啥优缺点？谢谢了！相关的知识，希望对你有一定的参考价值。

Maven是一个项目构建工具,服务与构建.使用Maven配置好项目后,输入简单的命令,如:mvn clean install,Maven会帮我们处理那些繁琐的任务.
Maven是跨平台的.
Maven最大化的消除了构建的重复.
Maven可以帮助我们标准化构建过程.所有的项目都是简单一致的,简化了学习成本.
总之,Maven作为一个构建工具,不仅帮我们自动化构建,还能抽象构建过程,提供构建任务实现.他跨平台,对外提供一致的操作接口,这一切足以使他成为优秀的,流行的构建工具.
但是Maven不仅是构建工具,他还是一个依赖管理工具和项目信息管理工具.他还提供了中央仓库,能帮我们自动下载构件.
使用Maven还能享受一个额外的好处，即Maven对于项目目录结构、测试用例命名方式等内容都有既定的规则，只要遵循了这些成熟的规则，用户在项目间切换的时候就免去了额外的学习成本，可以说是约定优于配置参考技术A 主要是ssm框架一般需要引入的jar包较多，这样一来拷贝，查找jar包，配置项目环境等操作所花费的时间都比较多，非常繁琐；而采用Maven架构，我们就可以在pom.xml文件中配置jar包下载源，以后直接在文件中就可以添加或删除jar包依赖了。

SSM-maven 简单整合

记一次简单的整合了一次SSM框架过程，因为好久不用了在过程中发生了一些问题。后续我会在继续在此基础上整合其他框架进来。

本次整合用到的框架有：

spring & springmvc
mybatis （mybatis Plus 好像是一个有意思的东西）

mybatis-spring

applicationContext-transaction.xml

三种事务配置方式，在验证事务的过程中遇到了一个有趣的问题。目前还未搞清楚原因先记录下，等深入研究后补全原因。
使用@Transactional 注解或者在xml中配置事务传播机制为【PROPAGATION_SUPPORTS】【readOnly = true】，这个时候方法还是可以写入数据库。
但是仅配置【readOnly = true】的情况下做数据修改操作的时候事务就起作用了，会抛出一个只读的异常。
【PROPAGATION_REQUIRED】事务是正常的。
这是什么原因呢？待后续研究后更新...
