java mvc模式的service的设计

个人理解

在MVC模式中为了解耦派生出了controller,service,dao层
1. 在我看来controller是处理权限相关的事情
1. service层是处理业务逻辑以及最重要的事务控制多表插入回滚
1. dao层则是只做操作数据库部分

产生问题

那么我的两个不同的service如果都要对一个表进行插入操作,
而这个插入又会有多个表的插入复杂的业务,那么这一部分业务应该是放在service(把它称作serviceC)的,
那么问题就是我的serviceA对自己的表进行插入的时候同时要插入C表(和其派生表),
那么我的serviceA是不是应该把serviceC注入进来,还是说思路不对有什么其他方式实现,总不可能同样的逻辑再写一套吧,最主要还是事物的控制。

综合各位意见和大厂意见,service也可以分层,可以分专门处理数据的,处理业务逻辑的,以及多表联动的,这些也是层级调用,本质上还是service,但是命名需要有字的规范

相同的业务放在相同的service,而不是相同的表,如果同时插ac表,那么应该在dao体现,有不同的表。如果一个service对应一个表,叫作什么解耦

事务的传播行为

    propagation

            1.propagation_required 当前没有事务变创建一个事务,如有有则使用

            2.propagation_supports 支持当前事务,有则使用,没有则不使用

            3. propagation_mandatory  支持当前事务,有则使用,没有则抛出异常

            4.propagation_requires_new 无论有没有,都创建新事务

            5.propagation_not_supported  非事务方式提交,有则挂起该事务

            6.propagation_never 非事务提交,有则抛出异常

            7.propagation_nested 存在事务,在嵌套事务内执行,没有,则创建一个事务
serviceA的传播行为设置为.propagation_nested,具体用哪一中传播行为,你自己可以思量下

service层之间相互调用是不建议的,增加了耦合性,也不能在controller调用不同的service,所以只能在dao层做文章,把调用的方法封装到Dao层

主要看你想要实现什么事情,service不是只是方法的实现或者是接口的传递。mvc模式不是调用dao层的方法吗?

service是业务逻辑层,dao层是数据访问层,所以把数据访问的事情交给dao,serviceA对自己的表进行插入的时候同时要插入C表,那就将DaoC注入进ServiceA就行了

乐古 没有代码重复,按你的说法,同时插入三张表也要引入两个service,这样违背了service的初衷,service是执行业务逻辑,而不仅仅是做数据访问

按照我的理解:
1. 首先,MVC 里面应该不包含service的含义,如果操作足够简单,只需要control和dao存取数据就可以了。control涉及的范围比较大,包含处理请求,解析参数,处理业务逻辑和组装返回数据。
2.当control里面的业务逻辑比较复杂,重复的调用比较多,所以才会衍生出service,作用是为了封装相同或者类似的业务逻辑,同时便于拓展和解耦,大多数是为了解耦。解耦的能力需要看service的设计了。
3.问题中说serviceA引用到serviceC的代码,servive是业务逻辑的封装,不是请求访问表的封装,整体的功能应该放到serviceA里才是合适的,同时serviceA会引用daoA和daoC。如果serviceA引用到daoC里的逻辑其他地方也会引用,那本身这是两个业务逻辑,应该分开解耦。

小小菜鸟2020 首先公共的service是需要拆出来的,如果serviceA调用serviceC,会有事务问题。这个是正常的业务思路。spring本身使用事务也比较简单的。

seal_li
seal_li 不是只针对serviceA,这样的确把serviceC的所有功能让serviceA继承就解决了,更多的是类似半公共service,有多个service需要调用同一个serviceC(同时有多个dao逻辑)并且产生事务控制
大约一年之前 回复

如果业务逻辑很清晰且简单,建议serviceA重写该部分逻辑;如果serviceC逻辑也比较复杂,建议seviceA注入serviceC

看业务吧,因为,有时候插入A表的时候可能会更新缓存数据,这时候,就应该注入serviceA,然后在ServiceA里面添加插入的方法,插入的里面就会更新缓存等等,不同的逻辑,如果只是简简单单的插入的话,直接将daoA注入进来就比较
方便了,所以还是要看业务实际场景,来选择合适的注入方式.并不是单单为了解耦而解耦

在MVC模式下将浏览网页的用户信息写入后台数据库的处理流程问题

大家知道,在MVC模式下,是JSP-->SERVLET-->SERVICE-->DAO这种调用关系,就是说针对后台数据库的操作都是在DAO中实现。 有这样一个需求,用户用浏览器访问网页a.jsp,a.jsp非常简单,就是用户访问时显示个hello world,没有任何提交表单的操作。 现在需要获取访问页面的用户的两个信息,一个是IP,一个是user-agent,那么是不是我应该在a.jsp里调用SERVLET,在SERVLET中用request.getHeader之类的方法获得用户信息(IP和user-agent),然后通过调用SERVICE-->DAO来把用户信息写入数据库,写完数据库,SERVLET的任务就完成了,之后没有任何跳转之类的操作。 那么,这种没有提交表单的JSP里怎么调用SERVLET呢?是不是在a.jsp加载页面时用java script的onload中调用SERVLET呢? 总感觉上面的流程有点怪怪的感觉。。。。。 请大神指教,万分感谢!

请教一个在MVC模式下获取访问者IP的实现方法

有这样一个需求,很简单,就是用户访问网页时,获取到用户的IP,并写入数据库。 以前用model1模式开发时,很容易实现,就是在JSP中用request.getRemoteAddr()获取用户IP地址后,调用一个bean中的方法(将刚才获取的IP作为参数),直接写入数据库就可以了。 但现在用MVC模式开发,那么写入数据库的操作都在DAO层实现,是JSP-->SERVLET-->SERVICE-->DAO这种调用关系,也就是理论上JSP不能直接调用DAO中的写入数据库操作了(也不能直接调用SERVICE),而是要通过调用SERVLET来间接实现。 那么难道是在JSP加载页面时,在js的onload中调用SERVLET(SERVLET-->SERVICE-->DAO)来实现将用户IP写入数据库的操作吗? 请大神指点,谢谢!

spring mvc service单例问题

spring mvc 的项目,controller的注解@Scope("session"),是会话级别的。对于每一个用户请求都会产生实例,这没有问题。那我controller中通过@Autowired注入的service,它现在也是会话级别的?还是仍然是单例的?即:每个用户的请求都会产生一个controller实例,那service的实例是产生一个还是多个呢?谢谢。

创建容器出错'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping'

启动项目的时候报错: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping': Invocation of init method failed; nested exception is java.lang.NoSuchMethodError: org.springframework.aop.support.AopUtils.selectInvocableMethod(Ljava/lang/reflect/Method;Ljava/lang/Class;)Ljava/lang/reflect/Method; 我只在controller中写了一个简单的方法测试一下, 代码如下: ``` @Controller @RequestMapping(value ="/User") public class UserController { @RequestMapping(value ="/login.do") @ResponseBody public UserInfo login(){ return new UserInfo(); } } ``` springmvc的配置文件是这样: ``` <!-- 扫描web相关的bean --> <context:component-scan base-package="com.business.Controller"/> <!-- 开启SpringMVC注解模式 --> <mvc:annotation-driven> <mvc:message-converters> <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </mvc:message-converters> </mvc:annotation-driven> ``` service里还没创建类,Dao层使用mybatis-Generator插件自动生成的。想问下这到底是哪里除了问题?

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?

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...

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...

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...
