数组、List、Set、Map、Properties依赖注入格式

BookDao接口：

public interface BookDao {
    public void save();
}

BookDaoImpl实现类，并且有各个集合的set方法

import com.itheima.dao.BookDao;

import java.util.*;

public class BookDaoImpl implements BookDao {

    private int[] array;

    private List list;

    private Set set;

    private Map map;

    private Properties properties;
    
    
    
    public void setArray(int[] array) {
        this.array = array;
    }

    public void setList(List list) {
        this.list = list;
    }

    public void setSet(Set set) {
        this.set = set;
    }

    public void setMap(Map map) {
        this.map = map;
    }

    public void setProperties(Properties properties) {
        this.properties = properties;
    }

    
    
    public void save() {
        System.out.println("book dao save ...");

        System.out.println("遍历数组:" + Arrays.toString(array));

        System.out.println("遍历List" + list);

        System.out.println("遍历Set" + set);

        System.out.println("遍历Map" + map);

        System.out.println("遍历Properties" + properties);
    }
}

AppForDICollection运行：

import com.itheima.dao.BookDao;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class AppForDICollection {
    public static void main( String[] args ) {
        ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");

        BookDao bookDao = (BookDao) ctx.getBean("bookDao");

        bookDao.save();
    }
}

applicationContext.xml配置dao，并且用数组、list集合、set集合、msp集合、properties类进行分别注入。

        
        
            
                100
                200
                300
            
        
        
        
            
                itcast
                itheima
                boxuegu
                chuanzhihui
            
        
        
        
            
                itcast
                itheima
                boxuegu
                boxuegu
            
        
        
        
            
        
        
        
            
                china
                henan
                kaifeng
            
        
    

执行结果：

list和数组能够混用，一般来说标准的写。
