Test类：

 

package cn.lichen;

import java.util.Iterator;

public class TestUser {

@Test
public void testToString() {
BeanFactory factory = new ClassPathXmlApplicationContext(
"applicationContext.xml");
User user = (User) factory.getBean("user");
System.out.println("My name is " + user.getName() + "\n"
+ user.getAge() + "\n" + user.getBirthday().toString());

// 数组
System.out.println(user.getAnyPro()[0]);

// List集合
List<String> list = user.getListPro();
Iterator<String> it = list.iterator();
while (it.hasNext()) {
String value = it.next();
System.out.println(value);
}

// Set集合
Set<String> set = user.getSetPro();
for (Iterator<String> iterator = set.iterator(); iterator.hasNext();) {
String value = iterator.next();
System.out.println(value);
}

// map集合
Map<String, String> map = user.getMapPro();
Set<Entry<String, String>> entry = map.entrySet();
for (Iterator<Entry<String, String>> iterator = entry.iterator(); iterator
.hasNext();) {
Entry<String, String> mapEntry = iterator.next();
System.out.println(mapEntry.getKey() + "\t" + mapEntry.getValue());
}

//properties集合，以前 都没听说
Properties properties = user.getProperties();
Set<String> setProperties = properties.stringPropertyNames();
for (Iterator<String> iterator = setProperties.iterator(); iterator
.hasNext();) {
String key = iterator.next();
String value = properties.getProperty(key);
System.out.println("properties:" + "\t" + key + "\t" + value);
}

}

}

 

lib包无变化。
