我们对类中的参数注入的时候，有的时候，注入的是我们自己定义的类，而不是java基本的类型。
如下
Home.java是我们自己定义的类
package com.endual.bean;
public class Home {
private String address ;
private int phone ;
public String getAddress() {
return address;
}
public void setAddress(String address) {
this.address = address;
}
public int getPhone() {
return phone;
}
public void setPhone(int phone) {
this.phone = phone;
}
}People.java
package com.endual.bean;
import java.util.List;
import java.util.Map;
import java.util.Set;
public class People {
private Home home;
private Home[] homes;
private List<Home> lists;
private Map<Integer,Home> maps;
private Set<Home> sets;
public Home getHome() {
return home;
}
public void setHome(Home home) {
this.home = home;
}
public Home[] getHomes() {
return homes;
}
public void setHomes(Home[] homes) {
this.homes = homes;
}
public List<Home> getLists() {
return lists;
}
public void setLists(List<Home> lists) {
this.lists = lists;
}
public Map<Integer, Home> getMaps() {
return maps;
}
public void setMaps(Map<Integer, Home> maps) {
this.maps = maps;
}
public Set<Home> getSets() {
return sets;
}
public void setSets(Set<Home> sets) {
this.sets = sets;
}
}

测试
package com.endual.main;
import java.io.FileInputStream;
import java.io.InputStream;
import java.util.List;
import java.util.Map;
import java.util.Set;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
import com.endual.bean.Home;
import com.endual.bean.People;
public class MainRun {
public static void main(String[] args) {
// ClassPathXmlApplicationContext factory=new ClassPathXmlApplicationContext("bean.xml");
ApplicationContext context=new FileSystemXmlApplicationContext("src/applicationContext.xml");
People hello = (People)context.getBean("people");
Home home = hello.getHome() ;
System.out.println(home.getAddress());
Home[] homes = hello.getHomes() ;
System.out.println(homes[1].getAddress());
List<Home> lists = hello.getLists() ;
System.out.println(lists.get(0).getAddress());
Map<Integer,Home> maps = hello.getMaps() ;
System.out.println(maps.get(1).getAddress());
Set<Home> sets = hello.getSets() ;
System.out.println(sets.iterator().next().getAddress());
}
}
打印结果：
浙江工商大学people_home
浙江工商大学people_homes2
浙江工商大学lists1
浙江工商大学maps1
浙江工商大学set1
感受：
感觉到，其他自定义类的书写和我们一般的是一样的，就是用bean作为我们的参数的一个整体
