Spring入門_02_屬性注入

Spring 的set方法（屬性）注入

UserAction類中設置屬性和get、set方法。（實際上只須要set方法）

private List list = null;
private Set set = null;
private Map map = null;
private Properties props = null;
//get、set方法省略。

applicationContext.xml

<bean id="userAction" class="com.umgsai.spring.UserAction" scope="singleton">
    <property name="manager">
        <ref bean="userManager">
    </property>
    <property name="list">
        <list>
            <value>123</value>
            <ref local="cur">
        </list>
    </property>
    <property name="set">
        <set>
            <value>Hello</value>
            <value>12.36</value>
            <value>124</value>
            <value type="java.lang.String">true</value><!--指定type-->
        </set>
    </property>
    <property name="map">
        <map>
            <entry key="a1">
                <value>umgsai</value>
            </entry>
            <entry key="a2">
                <value>umgsai2</value>
            </entry>
        </map>
    </property>
    <property name="props">
        <props>
            <prop key="x1">as</prop>
            <prop key="x2">1265.3</prop>
        </props>
    </property> 
</bean>
