SSM-Spring教程（一）-IoC 控制翻转、SpringIoC技术、Bean之间的关系、作用域、生命周期、SpEL、各种属性的注入（基本类型、引用类型、集合类型）、Spring注解（详细）

SSM-Spring

什么是Spring：Spring提供了两个及其重要的技术，IoC |AOP

IoC：控制翻转 也叫DI技术（依赖注入）。之前呢，开发人员在使用某个类之前都需要先去创建对象（new），然后通过setter方法注入值，然后通过这个对象调用其中的方法。。。而现在通过Spring 的 IoC技术可以将对象的创建以及属性的赋值承包起来，这样的话，开发人员无需去创建对象，为属性赋值等。

AOP:面向方面编程（OOP）

1、开发步骤

①、导入jar包

commons-logging-1.1.1.jar
junit4.4.jar
spring-beans-4.0.2.RELEASE.jar
spring-context-4.0.2.RELEASE.jar
spring-core-4.0.2.RELEASE.jar
spring-expression-4.0.2.RELEASE.jar

②、创建spring的配置文件

③、配置相关对象

spring-01applicationContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
	
	<bean id="helloWorld" class="com.rock.spring.hello.HelloWorld">
		<property name="name" value="老张">property>
	bean>	
beans>
④、去IoC容器中获取这些对象
package com.rock.spring.hello;

import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class HelloWorldTest {
	@Test
	public void test1(){
		HelloWorld helloWorld =new HelloWorld();
		
		helloWorld.setName1("老张");
		
		helloWorld.hello();
	}
	public static void main(String[] args) {
//		HelloWorld helloWorld =new HelloWorld();
//		helloWorld.setName("老张");
		
//		①、创建Spring的IoC容器对象
//		ApplicationContext :是IoC容器对象
//		ClassPathXmlApplicationContext是ApplicationContext容器对象的一个具体实现，参数指定了spring的配置文件
		ApplicationContext ctx=new ClassPathXmlApplicationContext("spring-01applicationContext.xml");
//		②、去IoC容器中获取对象（根据IoC容器中的对象名获取对应的对象）
		HelloWorld helloWorld=(HelloWorld) ctx.getBean("helloWorld");
//		③、调用对象中的相关方法
		helloWorld.hello();
	}
	
	@Test
	public void testFirst(){
		
	}
	
}

2、Spring中bean的配置以及属性注入的细节

①、两种属性值注入方式

①、setter方法注入

②、构造器注入，通过bean的构造器先后顺序注入

spring-02beans.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
	
	
	
	<bean id="c1" class="com.rock.spring.beans.Car">
		<property name="brand">
			<value>>]]>value>
		property>
		<property name="price" value="1000000">property>
		<property name="maxspeed">
			<value>240value>
		property>
	bean>
	
	
	<bean id="car1" class="com.rock.spring.beans.Car">
		<property name="brand" value="Audi">property>
		<property name="price" value="3333333.5">property>
		<property name="maxspeed" value="240">property>
	bean>
	<bean id="car" class="com.rock.spring.beans.Car">
		<property name="brand">
			<value>>i]]>value>
		property>
		<property name="price" value="3333333.5">property>
		<property name="maxspeed" value="240">property>
	bean>
	
	<bean id="car2" class="com.rock.spring.beans.Car">
		
		
		
		<constructor-arg value="BMW" index="0">constructor-arg>
		<constructor-arg value="99999.9">constructor-arg>
		<constructor-arg value="240">constructor-arg>
	bean>
	
	<bean id="car3" class="com.rock.spring.beans.Car">
		<constructor-arg value="Audi">constructor-arg>
		<constructor-arg value="5555555.5">constructor-arg>
	bean>
	
	<bean id="car4" class="com.rock.spring.beans.Car">
		<constructor-arg value="Audi" type="java.lang.String">constructor-arg>
		<constructor-arg value="240"  type="double">constructor-arg>
	bean>
	
	
beans>

②、应用类型属性的注入

spring-03ObjectIn.xml

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

	
	<bean id="car" class="com.rock.spring.objectin.Car">
		<constructor-arg value="Audi">constructor-arg>
		<constructor-arg value="5555555.5">constructor-arg>
		<constructor-arg value="240">constructor-arg>
	bean>
	<bean id="car1" class="com.rock.spring.objectin.Car">
		<constructor-arg value="BMW">constructor-arg>
		<constructor-arg value="6555555.5">constructor-arg>
		<constructor-arg value="280">constructor-arg>
	bean>
	
	
	<bean id="person" class="com.rock.spring.objectin.Person">
		<property name="name" value="刘备">property>
		<property name="car" ref="car">property>
	bean>
	
	
	<bean id="address" class="com.rock.spring.objectin.Address">
		<constructor-arg value="大连">constructor-arg>
		<constructor-arg value="高新区光贤路">constructor-arg>
	bean>
	
	
	<bean id="person1" class="com.rock.spring.objectin.Person">
		<property name="name">
			<value>关羽value>
		property>
		<property name="car" ref="car1">property>
		<property name="address" ref="address">property>
	bean>
	
	<bean id="person2" class="com.rock.spring.objectin.Person">
		<property name="name">
			<value>张飞value>
		property>
		<property name="car" ref="car1">property>
		<property name="address">
			
			<bean class="com.rock.spring.objectin.Address">
				<constructor-arg value="北京市">constructor-arg>
				<constructor-arg value="海淀区中软村">constructor-arg>
			bean>
		property>
	bean>
beans>

import java.util.Properties;

public class DataSource {
	private Properties properties;
	public DataSource() {
		super();
	}
	public DataSource(Properties properties) {
		super();
		this.properties = properties;

		return properties;
	}

	public void setProperties(Properties properties) {
		this.properties = properties;
	}

	@Override
	public String toString() {
		return "DataSource [properties=" + properties + "]";
	}
	
}

PropertiesTest.java
package com.rock.spring.properties;

import org.junit.Before;

public class PropertiesTest {
	ApplicationContext ctx;
	@Before
	public void init(){
//		①、创建IoC容器对象
		ctx=new ClassPathXmlApplicationContext("spring-05properties.xml");
	}
	@Test
	public void testProperties(){
		DataSource ds=(DataSource) ctx.getBean("dataSource");

	}
}

⑤、part1总结

Spring框架
1、IoC技术（控制翻转）：也叫DI（依赖注入）
​ IoC容器：ApplicationContext ctx：就是IoC容器对象
​ ctx.getBean(“对象名”);
2、Aop技术：面向方面（切面）编程

3、关于bean属性值得注入

①、基本类型的注入
②、String类型的注入

<bean id="" class="">
    <property name="" value="">
bean>

③、对象属性的注入

<bean id="" class="">
    <property name="" ref="">
bean>

④、集合属性的注入List,Set,Map

<bean id="" class="">
    <property name="">  
        <list>		Set&List
            <ref bean="beanid1">
            <ref bean="beanid2">
        <list>
    property>
bean>
                
<bean id="" class="">
	<property name="">  
		<map>		Map
			<entry key|key-ref|value|value-ref="">
			<entry key="A0001" value-ref="person">
		<map>
	property>
bean>

⑤、Properties属性的注入

<bean id="" class="">
    <property name="">  
        <props>		Properties
            <prop key="K1">KValue1prop>
            <prop key="K2">KValue2prop>
        <props>
    property>
bean>

4、Spring命名空间 context|p|util
​ context：引用外部的属性文件

	<context:property-placeholder lication="">
	<context:property-placeholder location="classpath:db.properties"/>

​ 在当前的配置文件中通过${key}

<property name="driver" value="${oracle.driver}">

oracle.url=jdbc:oracle:thin:@127.0.0.1:1521:orcl
oracle.username=scott
oracle.password=tiger
oracle.driver=oracle.jdbc.OracleDriver

p:对bean属性的值的注入，即简化了配置


util:使用util中的list元素创建共享的集合

5、其他
​ ①、内部bean
​ ②、setter风格属性|构造注入
​ ③、setter注入和构造器注入可以混合使用

⑥、SpringBean之间的关系

1、依赖关系：表现的是IoC容器在创建对象的先后顺序
2、继承关系：表现在配置上的继承，而非java中的继承

⑦、Bean的作用域,IoCbean的作用域共有5个

Spring中bean的作用域

①、singleton ：单例作用域，，，

​ sigleton在项目 启动时，IoC容器就会根据配置创建这个bean对象。是bean的默认作用域
②、prototype ：原生作用域，，，

​ prototpye是在获取这个对象时，IoC容器才去创建这个bean对象
③、request
④、session
④、global

⑧、Bean的声明周期

Spring中bean的生命周期：

①、在bean的配置中可以通过init-method 和 destroy -method 来指定bean初始化方法和消亡方法

<bean id="car1" class="com.rock.spring.cycle.Car" 
p:brand="Audi" 
p:price="300000" 
p:maxspeed="240"
init-method="init1"
destroy-method="destroy1"
> bean>

②、开发人员可以通过创建BeanPostProcessor来设置bean的前置和后置处理器，来进一步干预bean的生命周期
注意：Bean的处理器不是针对某一个bean而是对IoC容器中的所有bean都起作用

	<bean id="person2" class="com.rock.spring.autowired.Person" autowire="byType">
		<property name="name" value="张飞">property>
	bean>
beans>


package com.rock.spring.autowired;

public class Person {
	private String name;
	private Car car;
	private Address address;
	
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public Car getCar() {
		return car;
	}
	public void setCar(Car car) { 
		this.car = car;
	}
	public Address getAddress() {
		return address;
	}
	public void setAddress(Address address) {
		this.address = address;
	}
	@Override
	public String toString() {
		return "Person [name=" + name + ", car=" + car + ", address=" + address + "]";
	}
	
}

|Spring中属性的注入？
①、setter注入
②、构造器注入
③、自动注入 autowire=“byName|byType” byType：若IoC容器中存在多个相同类型的对象，将不能注入成功
Spring IoC容器管理bean的生命周期
①、通过指定init-method destroy-method 执行初始化和消亡方法
②、bean的后置处理BeanProcessor（接口—>before|after）在bean初始化方法执行之前和执行之后调用before和after方法
注意：两个方法参数以及返回值的性质
参数1：bean对象（Object）
参数2：bean名称（String）
返回值：Object 返回给IoC的对象
③、Bean的创建
Ⅰ、通过静态（工厂）方法创建bean
Ⅱ、通过实例工厂方法创建bean
Ⅲ、通过FactoryBean创建bean
Spring中的表达式语言：SpEL
语法：#{}

⑩、Bean的创建方式

①、通过反射创建bean

②、通过工厂方法创建bean

​ 1）、静态工方法创建bean
第一：工厂中的方法必须是static修饰，返回值是要创建的bean对象类型
第二：这个静态工厂方法可以有参数，若有参数在配置文件中通过向这个参数注入相关的值
第三：在配置文件中配置的Bean类型，但是class要指向工厂类

​ 2）、实例工厂方法创建

③、通过FactoryBean创建

1、工厂方法创建bean
①、静态工厂方法创建bean
