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;
}
}
