Spring自动装配模式二：byName的解析
根据属性名自动装配。此选项将检查容器并根据名字查找与属性完全一致的bean，并将其与属性自动装配。例如，在bean定义中将autowire设置为byName，而该bean包含homeAddressServiceImpl属性（同时提供setHomeAddressServiceImpl(..)方法），Spring就会查找名为homeAddressServiceImpl的bean定义，并用它来装配给homeAddressServiceImpl属性。
配置文件如下：
<bean id="homeAddressServiceImpl" class="cn.csdn.service.HomeAddressServiceImpl"
scope="singleton">
<property name="address">
<value>北京海淀上地软件园</value>
</property>
</bean>
<bean id="empServiceImpl" class="cn.csdn.service.EmpServiceImpl"
scope="singleton" autowire="byName" />
cn.csdn.service.HomeAddressServiceImpl代码
public class HomeAddressServiceImpl extends AddressServiceImpl {
private String address;
public void setAddress(String address){
this.address=address;
}
public HomeAddressServiceImpl() {
super();
}
public HomeAddressServiceImpl(String address){
this.address=address;
}
}
cn.csdn.service.EmpServiceImpl 代码
package cn.csdn.service;
public class EmpServiceImpl {
private HomeAddressServiceImpl homeAddressServiceImpl;
public void setHomeAddressServiceImpl(
HomeAddressServiceImpl homeAddressServiceImpl) {
this.homeAddressServiceImpl = homeAddressServiceImpl;
}
}
