一丶spring介绍
spring:spring可以看做是项目的管家,负责管理项目中的所有对象(包括web层,service层和dao层)。还可以看作容器 融合其他框架的
- IOC(控制反转):传统的项目工程需要我们自己的new对象,自己调取对象的方法和属性 而使用spring就不用,它回事用工工厂模式自动帮我创建!
- DI(依赖注入):spring 使用javaBean对象的set方法或者带参数的构造方法为我们在创建对象时自动设置所需要的属性值
-
Aop(面向切面编程):在面向对象编程(oop)思想中,我们将事物抽成一个个对象,而在aop中我们将对象莫些类似的的方面抽成一个切面,对这个切面进行一些权限,事物,日志等处理。aop底层是动态代理哦!
我的理解更像是做小手术 切开小口子让项目的莫些功能得到增强 !
spring常用注解:
这里需要注意的是注解是需要在xml文件中配置后才能使用哦!
#(@Bean)注解表明该方法会返回一个对象,并需要将其注册为Spring应用上下文中的bean,并且可以在方法中完成依赖注入;
(@Configuration)注解表明此类为配置类,包含了Spring应用上下文中如何创建bean的细节;
(@Component)注解表明该类会作为组件类,并告知Spring要为此类创建bean;
(@ComponentScan(packName))注解表明在指定包下扫描带有Component注解的类,并为其创建bean;
#(@AutoWired)注解申明了依赖,自动装配,可以用于属性和set方法;
#(@Import(xxx.class))注解将括号中声明的JAVA配置类导入当前配置类;
#(@ImportResource(classpath:xxx.xml))注解将括号中声明的XML配置导入当前配置类;
#(@Profile())注解表明只有此Profile**时(配置spring.profile.active和spring.profile.default),此Bean才会被创建,没有Profile注解的总是会被创建;
#(@Conditional(? implents Condition))注解表明只有给定条件计算结果为true时才会创建bean,可以用于带@Bean注解的方法上,括号内为实现了
Condition接口的类;
#(@Primary)当匹配的Bean不止一个时,此注解可以设置首选,避免自动装配时的歧义性;
(@Qualifier)注解使用限定符,在可选Bean上缩小范围最终达到只有1个Bean满足所规定的限制条件;
#(@Scope)注解声明了bean的作用域;proxyMode属性设置作用域代理,代理对bean进行懒解释并将调用委托给会话/请求作用域内真正的bean;
(@Aspect)注解表明该类是一个切面;
-(@Pointcut)注解表明在一个@Aspect切面内定义可重用的切点
-(@After)注解表明通知方法会在目标方法返回或抛出异常后调用;
-(@AfterReturning)注解表明通知方法会在目标方法返回后调用;
-(@AfterThrowing)注解表明通知方法会在目标方法抛出异常后调用;
-(@Around)注解表明通知方法会将目标方法封装起来;该通知方法需要接受ProceedingJoinPoint作为参数,通过它来调用被通知的方法,当要将控制权交给被通知方法时,需要调用它的proceed方法;
-(@Before)注解表明通知方法会在目标方法调用之前执行;
-(@DeclareParents)注解表明将接口引入到bean中;所标注的静态属性指明了要引入的接口;
-(value)属性指定了哪种类型的bean要引入该接口,+号表示该类的所有子类且不包含该类自身;
-(defaultImpl)属性指定了为引入功能提供实现的类;
(@EnableAspectJ-AutoProxy)注解表明可以在配置类
@Configuration的类级别上使用此注解启动自动代理功能,自动代理会为使用
@Aspect注解的bean创建一个代理,此代理会围绕该切面的切点所匹配的bean;
(@EnableWebMvc)启用Spring MVC;
(@Controller)声明一个控制器,基于@Componet注解,辅助实现组件扫描;
-(@RequetsMapping)注解声明了它们所要处理的请求,可以在类和方法上声明;
-(value)指定了该方法索要处理的请求路径;
-(method)属性细化了它所处理的HTTP方法(get, post);
(@RequestParam)
(@PathVariable)
二丶spring mvc介绍
springmvc:springmvc是spring框架的一个模块,springmvc和spring无需通过中间整合层进行整合。springmvc是一个基于mvc的web框架。
springmvc常用注解
springmvc常用注解详解
三丶mybatis介绍
mybatis:是一个持久型数据连接框架,它内部集齐连接池和缓存机制,可减少不必要的资源浪费,反应更快捷
、Mybatis中的缓存
什么是缓存
存在于内存中的临时数据。
为什么使用缓存
减少和数据库的交互次数,提高执行效率。
什么样的数据能使用缓存,什么样的数据不能使用
适用于缓存:
经常查询并且不经常改变的。
数据的正确与否对最终结果影响不大的。
不适用于缓存:
经常改变的数据
数据的正确与否对最终结果影响很大的。
例如:商品的库存,银行的汇率,股市的牌价。
Mybatis中的一级缓存和二级缓存
一级缓存:
它指的是Mybatis中SqlSession对象的缓存。
当我们执行查询之后,查询的结果会同时存入到SqlSession为我们提供一块区域中。
该区域的结构是一个Map。当我们再次查询同样的数据,mybatis会先去sqlsession中
查询是否有,有的话直接拿出来用。
当SqlSession对象消失时,mybatis的一级缓存也就消失了。
二级缓存:
它指的是Mybatis中SqlSessionFactory对象的缓存。由同一个SqlSessionFactory对象创建的SqlSession共享其缓存。
二级缓存的使用步骤:
第一步:让Mybatis框架支持二级缓存(在SqlMapConfig.xml中配置)
第二步:让当前的映射文件支持二级缓存(在IUserDao.xml中配置)
第三步:让当前的操作支持二级缓存(在select标签中配置)
3、Mybatis中的注解开发
环境搭建
单表CRUD操作(代理Dao方式)
多表查询操作
缓存的配置
以下是mapper 映射的配置文件 可以配合注解使用更为方便
