package Bean.superIOCmethod;

public class Person {
private Son son;
private String age;
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public Son getSon() {
return son;
}
public void setSon(Son son) {
this.son = son;
}
}

package Bean.superIOCmethod;

public class Son {
private String age;

public String getAge() {
return age;
}

public void setAge(String age) {
this.age = age;
}
}

package Bean.superIOCmethod;
public class Field {
public static final String TEST_FIELD="welcom";
public String getValue(){
return "test";
}
public static String getStaticValue(){
return "static test";
}
}

测试代码
public static void main(String[] args) throws Exception {

String path=new Test().getClass().getResource("/").getPath();
String realpath=path.substring(1, path.length());
ApplicationContext context=new FileSystemXmlApplicationContext(realpath+"/superIOCmethod.xml");
Son son1=(Son)context.getBean("son");
Son son2=(Son)context.getBean("staticson");

System.out.println("person age is:"+son1.getAge());
System.out.println("person age is:"+son2.getAge());
System.out.println(context.getBean("sysProps"));
System.out.println(context.getBean("javaversion"));
}

结果：

person age is:test

person age is:static test
