Spring自动装配模式二：byName的解析

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;

}

 

}
