Spring 属性注入（int ,String, List, Map, Set, String[])

1.JavaBean




import java.util.List;

import java.util.Map;

import java.util.Set;



public class Test {

private int intValue;

private String strValue;

private List listValue;

private Map mapValue;

private Set<String> setValue;

private String[] arrayValue;



public int getIntValue() {

return intValue;

}



public void setIntValue(int intValue) {

this.intValue = intValue;

}



public String getStrValue() {

return strValue;

}



public void setStrValue(String strValue) {

this.strValue = strValue;

}



public List getListValue() {

return listValue;

}



public void setListValue(List listValue) {

this.listValue = listValue;

}



public Map getMapValue() {

return mapValue;

}



public void setMapValue(Map mapValue) {

this.mapValue = mapValue;

}



public Set getSetValue() {

return setValue;

}



public void setSetValue(Set setValue) {

this.setValue = setValue;

}



public String[] getArrayValue() {

return arrayValue;

}



public void setArrayValue(String[] arrayValue) {

this.arrayValue = arrayValue;

}

}

import java.util.Iterator;

import java.util.List;

import java.util.Map;

import java.util.Set;

import java.util.Map.Entry;



import org.apache.xbean.spring.context.ClassPathXmlApplicationContext;

import org.springframework.beans.factory.BeanFactory;



public class TestSpringDI {



private static BeanFactory factory;



public static void main(String[] args) {

factory = new ClassPathXmlApplicationContext(

"conf/spring/applicationContext1Test.xml");

testBeanDemo();



}



public static void testBeanDemo() {

Test test = (Test) factory.getBean("TestBean");



System.out.println("beanDemo.intValue=" + test.getIntValue());



System.out.println("beanDemo.strValue=" + test.getStrValue());

List listValue = test.getListValue();

System.out.println("beanDemo.listValue=");

if (listValue != null) {

for (Iterator it = listValue.iterator(); it.hasNext();) {

System.out.println((String) it.next());

}

}



System.out.println("beanDemo.setValue=");

Set setValue = test.getSetValue();

if (setValue != null) {

for (Iterator it = setValue.iterator(); it.hasNext();) {

System.out.println(it.next());

}

}



System.out.println("beanDemo.arrayValue=");

String[] arrayValue = test.getArrayValue();

if (arrayValue != null) {

for (int i = 0; i < arrayValue.length; i++) {

System.out.println(arrayValue[i]);

}

}



System.out.println("beanDemo.mapValue=");

Map mapValue = test.getMapValue();

if (mapValue != null) {

Set<Map.Entry> set = mapValue.entrySet();

for (Iterator it = set.iterator(); it.hasNext();) {

System.out.println(entry.getKey() + " = " + entry.getValue());

}

}
