applicationContext.xml 配置属性和对象ref指向

<strong><span style="font-size:18px;"><bean id = "helloworld" class="com.huoxin.bean1.HelloWorld"><property name="name" value="123"></property><property name="age" value="123"></property><property name="number" value="123"></property><property name="phone" value="123"></property><property name="tt" ref="cc"></property></bean><bean id ="cc" class="com.huoxin.bean1.TT"><property name="ppp" value = "250"></property></bean></span></strong>

tt是对象，需要自己创建实体类，  ppp是TT尸体的属性
