Spring 注入集合和数组

Spring 注入集合和数组
1、创建类、声明数组集合（List、Map、Set）

public class Stu {

    private String[] arrays;
    private List list;
    private Map map;
    private Set set;

    public void setArrays(String[] arrays) {
        this.arrays = arrays;
    }

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

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

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

    @Override
    public String toString() {
        return "Stu{" +
                "arrays=" + Arrays.toString(arrays) +
                ", list=" + list +
                ", map=" + map +
                ", set=" + set +
                '}';
    }
}

2、配置文件中注入属性

 
        
            
                qq
                yy
            
        
        
            
                mx
                qxf
            
        
        
            
        
        
            
                c
                java
            
        
    

3.测试

 @Test
    public void test1(){
        ApplicationContext context = new ClassPathXmlApplicationContext("bean1.xml");
        Stu stu = context.getBean("stu", Stu.class);
        System.out.println(stu.toString());
    }
