Spring的分模块开发的配置

分模块开发配置

一、在加载配置文件的时候，加载多个

准备两个配置文件分别为
applicationContext.xml

applicationContext2.xml

package com.itzheng.spring.demo5;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/*
 * 复杂类型的属性注入
 */
public class SpringDemo5 {
	@Test
	public void demo1() {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml","applicationContext2.xml");
		CollectionBean collectionBean = (CollectionBean) applicationContext.getBean("collectionBean");
		System.out.println(collectionBean);
	}
}

二、在一个配置文件当中引入多个配置文件

import

package com.itzheng.spring.demo5;
import org.junit.Test;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
/*
 * 复杂类型的属性注入
 */
public class SpringDemo5 {
	@Test
	public void demo1() {
		ApplicationContext applicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
		CollectionBean collectionBean = (CollectionBean) applicationContext.getBean("collectionBean");
		System.out.println(collectionBean);
	}
}

三、完成测试代码

package com.itzheng.spring.demo5;
import java.util.Arrays;
import java.util.List;
import java.util.Map;
import java.util.Set;
/*
 * 集合属性的注入：
 */
public class CollectionBean {
	private String[] arrs;
	private List<String> list;
	private Set<String> set;
	private Map<String, String> map;
	public void setArrs(String[] arrs) {
		this.arrs = arrs;
	}
	public void setList(List<String> list) {
		this.list = list;
	}
	public void setSet(Set<String> set) {
		this.set = set;
	}
	public void setMap(Map<String, String> map) {
		this.map = map;
	}
	@Override
	public String toString() {
		return "CollectionBean [arrs=" + Arrays.toString(arrs) + ", list=" + list + ", set=" + set + ", map=" + map
				+ "]";
	}
}
