Spring整理2 -- 普通属性注入

可以根据配置文件的信息动态的对象行为，动态的注入对象的属性值。下面我们将基本数据类型、String类型、数组类型以及集合类型进行动态的注入。

例子代码如下：

对象Bean1：

public class Bean1 {

    private String strValue;

    private int intValue;   

    private List listValue; 

    private Set setValue;   

    private String[] arrayValue;   

    private Map mapValue;   

配置文件applicationContext.xml：

    <bean id="bean1" class="spring.Bean1">

       <property name="strValue" value="Hello" />

       <property name="intValue">

           <value>123</value>

       </property>

       <property name="listValue">

           <list>

              <value>list1</value>

              <value>list2</value>

           </list>

       </property>

       <property name="setValue">

           <set>

              <value>set1</value>

              <value>set2</value>

           </set>

       </property>

       <property name="arrayValue">

           <list>

              <value>array1</value>

              <value>array2</value>

           </list>

       </property>

       <property name="mapValue">

           <map>

              <entry key="k1" value="v1" />

              <entry key="k2" value="v2" />

           </map>

       </property>

    </bean>

测试代码：

public class InjectionTest extends TestCase {

    private BeanFactory factory;   

    @Override

    protected void setUp() throws Exception {

       factory = new ClassPathXmlApplicationContext

("applicationContext.xml");

    }

    public void testInjection1() {

       Bean1 bean1 = (Bean1)factory.getBean("bean1");      

       System.out.println("bean1.strValue=" + bean1.getStrValue());

       System.out.println("bean1.intValue=" + bean1.getIntValue());

       System.out.println("bean1.listValue=" + bean1.getListValue());

       System.out.println("bean1.setValue=" + bean1.getSetValue());

       System.out.println("bean1.arrayValue=" +

bean1.getArrayValue());

       System.out.println("bean1.mapValue=" + bean1.getMapValue());

    }  

}
