spring 注入集合类型 List、Set、Map

首先先看用到的类：

Class1,Class2

代码：

package my.spring.fuck;

public class Class1 implements Interface1{
    private String a;

    public String getA() {
        return a;
    }

    public void setA(String a) {
        this.a = a;
    }
    public void eat(String s){
        System.out.println(s+a);
    }
}

package my.spring.fuck;

import java.util.Iterator;
import java.util.List;
import java.util.Map;
import java.util.Set;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class Class2 {
    private List<Class1> fuckList1;//集合统一装入Class1
    private List fuckList2;

    private Set<Class1> fuckSet1;
    private Set fuckSet2;

    private Map<String,String> fuckMap1;
    private Map<String,Class1> fuckMap2;

    public static void main(String[] args){
        ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
        //Class2 c2=(Class2)ac.getBean("c2");
        Class2 c2=ac.getBean(Class2.class);
        c2.print();
    }

    public void print(){
        System.out.println("this is fuckList1");
        for(Class1 c1:fuckList1){
            c1.eat("");
        }

        System.out.println("this is fuckList2");
        for(int i=0;i<fuckList2.size();i++){
            ((Class1)fuckList2.get(i)).eat("");
        }

        System.out.println("this is fuckSet1");
        for(Class1 c1:fuckSet1){
            c1.eat("");
        }

        System.out.println("this is fuckSet2");
        Iterator<Class1> iterator=fuckSet2.iterator();
        while(iterator.hasNext()){
            (iterator.next()).eat("");
        }

        System.out.println("this is fuckMap1");
        System.out.println(fuckMap1.get("mapKey1"));

        System.out.println("this is fuckMap2");
        Class1 c1=fuckMap2.get("mapKey1");
        c1.eat("");
    }

    public List<Class1> getFuckList1() {
        return fuckList1;
    }

    public void setFuckList1(List<Class1> fuckList1) {
        this.fuckList1 = fuckList1;
    }

    public List getFuckList2() {
        return fuckList2;
    }

    public void setFuckList2(List fuckList2) {
        this.fuckList2 = fuckList2;
    }

    public Set<Class1> getFuckSet1() {
        return fuckSet1;
    }

    public void setFuckSet1(Set<Class1> fuckSet1) {
        this.fuckSet1 = fuckSet1;
    }

    public Set getFuckSet2() {
        return fuckSet2;
    }

    public void setFuckSet2(Set fuckSet2) {
        this.fuckSet2 = fuckSet2;
    }

    public Map<String, String> getFuckMap1() {
        return fuckMap1;
    }

    public void setFuckMap1(Map<String, String> fuckMap1) {
        this.fuckMap1 = fuckMap1;
    }

    public Map<String, Class1> getFuckMap2() {
        return fuckMap2;
    }

    public void setFuckMap2(Map<String, Class1> fuckMap2) {
        this.fuckMap2 = fuckMap2;
    }

}

运行Class2，控制台输出如下：

this is fuckList1
i am a
i am a
this is fuckList2
i am a
i am a
this is fuckSet1
i am a
this is fuckSet2
i am a
this is fuckMap1
mapValue1
this is fuckMap2
i am a
