【Spring】DI的各种类型变量注入方法

public class Student {
	private String name;
	private Address address;
	private String[] books;
	private List hobbies;
	private Set games;
	private Map cards;
	private String wife;
	private Properties info;
	
	public void show() {
		System.out.println
			("Student's name = " + name + ",address = " + address.getAddress());
		
		System.out.print("books = ");
		
		for(String string:books) {
			System.out.print(string + "  ");
		}
		System.out.println();
		
		System.out.println("hobbies = " + hobbies);
		
		System.out.println("games = " + games);
		
		System.out.println("bank cards = " + cards);
		
		System.out.println("wife = " + wife);
		
		System.out.println("info = " + info);
	}
	
	public void setName(String name) {
		this.name = name;
	}
	
	public void setAddress(Address address) {
		this.address = address;
	}
	
	public void setBooks(String[] books) {
		this.books = books;
	}
	
	public void setHobbies(List hobbies) {
		this.hobbies = hobbies;
	}
	
	public void setGames(Set games) {
		this.games = games;
	}
	
	public void setCards(Map cards) {
		this.cards = cards;
	}
	
	public void setWife(String wife) {
		this.wife = wife;
	}
	
	public void setInfo(Properties info) {
		this.info = info;
	}
}

public class Test {
	public static void main(String[] args) {
		ApplicationContext ac = new ClassPathXmlApplicationContext("Beans.xml");
		Student student = (Student) ac.getBean("student");
		student.show();
	}
}

2.类注入

public class Address {
	private String address;
	
	public String getAddress() {
		return address;
	}
	
	public void setAddress(String address) {
		this.address = address;
	}
}
