J2EE_实验报告7_Spring的IOC

J2EE实验报告实验内容1功能描述、掌握Spring框架的建立步骤；、掌握Spring的Ioc注入方式：传值注入和构造注入；、掌握Spring的静态工厂注入方式；、掌握Spring的实例工厂注入方式。

2实验步骤搭建Spring 框架(0) 新建web project项目，项目名称自定义（我取名为EX_Ioc）；(1) 将spring需要的jar包拷贝到______下；（2）在src下新建文件<xml version=""encoding="UTF-8"><beansxmlns=""xmlns:xsi=""xmlns:p=""xmlns:aop=""xsi:schemaLocation=""></beans>注入普通类及属性（1）在src下新增包，在该包下新建类：package class Person {private String name;public void sayHello(){"hello, i am " + name);}//省略get set 方法}（2）在文件中添加配置<!-- frist 配置简单类及属性 --><bean id="person"class="____"><property name="____"value="xmut"></property> </bean>（3）编写测试代码在src下新增包，在该包下新建类：package class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("");Person person = (______) ("______");();}}（4）运行测试代码，查看结果。

配置类及使用bean--传值注入（1）在src下新增包，在该包下新建接口、和类、、、package interface IPerson {public void userAxe();}package interface IAxe {public void chop();}package class Chinese implements IPerson { private IAxe axe;public void useAxe() {();}}package class American implements IPerson { private IAxe axe;public void useAxe() {();}}package class SteelAxe implements IAxe { public void chop() {"steelAxe is quick!!!");}}package class StoneAxe implements IAxe { public void chop() {"stoneAxe is slow!!!");}}（2）在文件中添加配置<!-- second 配置类及使用bean --><bean id="stoneAxe"class="________"></bean><bean id="steelAxe"class="________"></bean><bean id="chinese"class="________"><property name="axe"ref="________"></property> </bean><bean id="american"class="________"><property name="axe"ref="stoneAxe"></property> </bean>（3）编写测试代码修改类：package class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("");//second 配置类及使用beanChinese chinese = (Chinese) ("____");();American american = (American) ("____");();}}（4）运行测试代码，查看结果。

配置类及使用bean--构造注入（1）在包下，新建类package class France implements IPerson {private IAxe axe;private IAxe axe2;private String name;public France() {}public France(IAxe axe,IAxe axe2,String name) { = axe;= axe2;= name;}public void useAxe() {();();}}（2）在文件中添加配置<bean id="france"class="______"><constructor-arg ref="____"></constructor-arg><constructor-arg ref="____"></constructor-arg><constructor-arg value="____"></constructor-arg></bean>（3）编写测试代码修改类：package class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("");//构造注入France france = (France) ("_____");();}}（4）运行测试代码，查看结果。

静态工厂注入（1）在src下新增包，在该包下新建类、、和接口package interface IBeing {public void ___________;}package interface Dog implements IBeing {private String name;public void sayHello(){"Hello,i am dog!My name is:"+name);}}package interface Cat implements IBeing {private String name;public void sayHello(){"Hello,i am cat!My name is:"+name);}}package class Factory {public static IBeing getBeing(String type){if("____")){return new Dog();}else {return new Cat();}}}（2）在文件中添加配置<!-- 静态工厂生成bean --><bean id="dog"class="____"factory-method="getBeing"> <constructor-arg value="dog"></constructor-arg><property name="name"value="____"></property> </bean><bean id="cat"class="____"factory-method="getBeing"> <constructor-arg value="cat"></constructor-arg><property name="name"value="____"></property> </bean>（3）编写测试代码修改类：package class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("");//静态工厂生成beanDog dog = (Dog) ("____");();Cat cat = (Cat) ("____");();}}（4）运行测试代码，查看结果。

实例工厂注入（1）在src下新增包，在该包下新建类、、和接口package fourth;public interface IPerson {public void ______________();}package fourth;public interface Chinese implements IPerson { private String name;public void sayHello(){"Hello,i am chinese!My name is:"+name);}}package fourth;public interface American implements IPerson {private String name;public void sayHello(){"Hello,i am american!My name is:"+name);}}package class Factory {public IPerson getPerson (String type){if("____")){return new Chinese();}else {return new ________;}}}（2）在文件中添加配置<!-- 实例工厂构造bean --><bean id="f"class="________"></bean><bean id="chn"factory-bean="___"factory-method="getPerson"> <constructor-arg value="chn"></constructor-arg><property name="name"value="______"></property> </bean><bean id="ame"factory-bean="__"factory-method="getPerson"> <constructor-arg value="ame"></constructor-arg><property name="name"value="______"></property> </bean>（3）编写测试代码修改类：package class MyTest{public static void main(String[] args) {ApplicationContext apc = new ______("");//实例工厂生成beanChinese chn = ___________;();American ame = ___________;();}}（4）运行测试代码，查看结果。
