Spring自动装配模式四：constructor的解析
Spring自动装配模式四：constructor的解析
与byType的方式类似，不同之处在于它应用于构造器参数。如果在容器中没有找到与构造器参数类型一致的bean，那么将会抛出异常
<bean id="homeAddressServiceImpl" autowire="constructor" />


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 {

/**公司地址*/
private AddressServiceImpl companyAddress;

public EmpServiceImpl(AddressServiceImpl companyAddress) {
super();
this.companyAddress = companyAddress;
}

}
