Geronimo中GBean的摘引

Geronimo中GBean的引用
Geronimo中GBean的引用。

1 在GBean中定义对另外一个GBean的引用。

public class CatGBean {
    private DogGBean dogGBean;
}

2 在构造函数中初始化该引用。

public CatGBean(DogGBean dogGBean) {
   this.dogGBean = dogGBean;
}

3 GBean都是用GBeanInfo描述的，所以在GBean中对该引用增加描述。

static {                    
  GBeanInfoBuilder infoBuilder = new GBeanInfoBuilder("MyCatGBean",
				CatGBean.class);

  infoBuilder.addAttribute("name", String.class, true);
  infoBuilder.addReference("DogGBean", DogGBean.class);
  infoBuilder.setConstructor(new String[] { "DogGBean" });

  GBEAN_INFO = infoBuilder.getBeanInfo();
}

4 在deployplan中配置GBean.

	<gbean name="dogGBean" class="allenG.DogGBean"></gbean>
	<gbean name="catGBean" class="allenG.CatGBean">
		<reference name="DogGBean">
			<name>dogGBean</name>
		</reference>
	</gbean>
