无法在 Spring 中使用构造函数自动连接 bean

Question

我是春天的新手。我正在尝试使用弹簧使用构造函数自动连接 bean。这是代码

<bean id="location" class="com.ibm.spring.Location">
    <constructor-arg name="pincode" value="110976"></constructor-arg>
</bean>
<bean id="address" class="com.ibm.spring.Address">
    <property name="id" value="2"></property>
    <property name="street" value="shahjahan"></property>
</bean>

位置类

public class Location {
private Address address;
private String pincode;

public void setAddress(Address address) {
    this.address = address;
}
@Autowired
public Location(Address address, String pincode) {
    super();
    this.address = address;
    this.pincode = pincode;
}
public void getTotalAddress() {
    System.out.println(this.pincode + "::"+this.address);
}
}

地址类

public class Address {
private int id;
private String street;
public int getId() {
    return id;
}
public void setId(int id) {
    this.id = id;
}
public String getStreet() {
    return street;
}
public void setStreet(String street) {
    this.street = "Kkp";
}
@Override
public String toString() {
    return "Address [id=" + id + ", street=" + street + "]";
}

测试 仪

 public class SpringTester {
public static void main(String[] args) {
    String configLoc = "com/ibm/spring/config/applicationContext.xml";
    ApplicationContext ctx = new ClassPathXmlApplicationContext(configLoc);
    Location l = (Location) ctx.getBean("location");
    l.getTotalAddress();
}
}

我正在通过构造函数参数设置其中一个字段值，并且应该注入类。 这里的问题可能是什么？

错误日志显示

Error creating bean with name 'location' defined in class path resource [com/ibm/spring/config/applicationContext.xml]: Unsatisfied dependency expressed through constructor parameter 0: Ambiguous argument values for parameter of type [com.ibm.spring.Address] - did you specify the correct bean references as arguments?

Answer 1

位置似乎有两个参数，因此：

<bean id="location" class="com.ibm.spring.Location">
    <constructor-arg name="pincode" value="110976"></constructor-arg>
     <constructor-arg ref="address"></constructor-arg>
</bean>
