1、父工程pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

    <artifactId>pro-ssm</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>pom</packaging>
    <modules>
        <module>pro04-spring-ioc-xml</module>
    </modules>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <spring.version>6.0.6</spring.version>
        <junit.version>5.3.1</junit.version>
    </properties>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework</groupId>
                <artifactId>spring-context</artifactId>

            </dependency>
        </dependencies>
    </dependencyManagement>

</project>

2、子工程pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <version>1.0-SNAPSHOT</version>
    </parent>

    <artifactId>pro04-spring-ioc-xml</artifactId>

    <properties>
        <maven.compiler.source>17</maven.compiler.source>
        <maven.compiler.target>17</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>

            <artifactId>junit-jupiter-api</artifactId>
        </dependency>
    </dependencies>

</project>

3、Person.java

package com.atguigu.ioc;

public class Person {

    public void sayHello() {
        System.out.println("Hello Spring!");
    }
}

4、applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<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="p01" class="com.atguigu.ioc.Person"></bean>
        
</beans>

5、PersonTest.java

package com.atguigu.ioc;
import org.junit.jupiter.api.Test;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
public class PersonTest {
    @Test
    public void test01() {
        new Person().sayHello();
    }
    @Test
    public void test02() {
        BeanFactory beanFactory = new ClassPathXmlApplicationContext("applicationContext.xml");
        Person p01 = (Person) beanFactory.getBean("p01");
        p01.sayHello();

    }
