02. Spring- 스프링코어기본 - 세터주입(Maven Project)

 

1. 메이븐 프로젝트 만들기

가. Other -> New -> Maven Project

 

 

나. Build Path -> Configure Build Path

 

 

 

다. pom.xml 코드 수정

<?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"

라. test파일 Delete -> Update Project 후 Maven Dependencies 새로운 .jar 확인

 

 

 

2. 자바빈 생성

2.1 DI에 대한 3단계

 

가. POJO(Plain Old Java Object) 클래스 만들기

 

 

 

Employee.java 코드

package com.khinfo.spring.springcore;

public class Employee {
    private int id;
    private String name;

    public int getId() {
        return id;
    }

    public void setId(int id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
    
    @Override
    public String toString() {
        return "Employee [id=" + id + ", name=" + name + "]";
   
}
}

 

 

나. 설정파일 만들기

 

config.xml 코드

<beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p"
  xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd">
<bean name="emp" class="com.khinfo.spring.springcore.Employee">
<property name="id">
<value>25</value>
</property>
<property name="name">
<value>JMJ</value>
</property>
</bean>
</beans>

 

 

다. 테스트 클래스 만들기

 

Test.java 코드

package com.khinfo.spring.springcore;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Test {

	public static void main(String[] args) {
		ClassPathXmlApplicationContext ctx = 
			    new ClassPathXmlApplicationContext(
			        "classpath:config.xml");
		// 빈 객체 얻어옴
		Employee employee = (Employee)ctx.getBean("emp");
		System.out.println(employee);
		ctx.close();
		
		
		
	}
}

 

+ 디렉토리 경로구성

 

라. 결과
