• Person

public class Person {private String pname;private Integer age;private Address homeAddr;private Address companyAddr;public String getPname() {return pname;}public void setPname(String pname) {this.pname = pname;}public Integer getAge() {return age;}public void setAge(Integer age) {this.age = age;}public Address getHomeAddr() {return homeAddr;}public void setHomeAddr(Address homeAddr) {this.homeAddr = homeAddr;}public Address getCompanyAddr() {return companyAddr;}public void setCompanyAddr(Address companyAddr) {this.companyAddr = companyAddr;}
}

• Address

public class Address {private String addr;private String tel;public String getAddr() {return addr;}public void setAddr(String addr) {this.addr = addr;}public String getTel() {return tel;}public void setTel(String tel) {this.tel = tel;}@Overridepublic String toString() {return "Address{" +"addr='" + addr + '\'' +", tel='" + tel + '\'' +'}';}
}

• 测试

	 @Testpublic void demo01(){String xmlPath = "p.xml";ApplicationContext applicationContext = new ClassPathXmlApplicationContext(xmlPath);Person person = (Person) applicationContext.getBean("personId");System.out.println(person.getPname());System.out.println(person.getAge());System.out.println(person.getCompanyAddr());System.out.println(person.getHomeAddr());}
