Question

我创建了一个类（名为iperfAndroidApp），它实现了一些接口（命名为AppService），并创建了另一个使用此iperfAndroidApp的类（命名为IperfApp）.IperfApp应该是其他项目的API。我做了这一切，以便将来能够在Android实例和IOS之间进行替换。我希望iperfAndroidApp类将成为xml文件中的bean。

我得到堆栈的意思是IperfApp在构造函数中获取一些参数（来自外部项目），我想将它们绑定到该bean的构造函数，所以我不必使用“new”（行） 8）。

我删除了不相关的部分以便于阅读。

//THE API THAT I AM CREATING
public class IperfApp {
//THE SERVICE THAT SHOULD BE INITIALIZED WITH ANDROID OR IOS
 AppService iperf;

 //I WANT TO PASS THE ARGUMENTS TO THE BEAN INSTEAD OF USING NEW
 public IperfApp(List<String> udids, List<String> commands, int runTime) {
 iperf=new IperfAndroidApp(udids, commands, runTime);
 }

...
}




//THE BEAN I WANT TO USE
public class IperfAndroidApp extends AndroidApp {

    private AndroidServer androidServer;
    private List<String> commands;
    private int runTime;

    public IperfAndroidApp(List<String> udids, List<String> commands, int runTime) {
        super(udids);
        this.commands = commands;
        this.runTime = runTime;
    }
....
}



public abstract class AndroidApp extends AppClient {...}
public abstract class AppClient implements AppService {...}

spring配置文件中的bean：

 <bean id="iperfInstance" 
  class="com.airspan.testspan.smarphones.Client.IperfAndroidApp" scope="singleton">
 <!--  want to bind args from the code here -->
 </bean>

我也尝试过使用spring class配置的不同方法

@Configurable
@ComponentScan("com.airspan.testspan.smarphones")
@PropertySource("classpath:config.properties")
public class AppConfigurations {
 //--------- to load the config.property file need to initialize it for spring-----------
 @Bean
 public static PropertySourcesPlaceholderConfigurer
 propertySourcesPlaceHolderConfigurer() {
 return new PropertySourcesPlaceholderConfigurer();
 }


 //---------------------Beans of Apps------------------------
 @Bean
 public IperfAndroidApp iperfAppInstance(List<String> udids, List<String> commands, int runTime){
 return new IperfAndroidApp(udids, commands, runTime);
 }

}
public class IperfAppRunner extends AppRunner {
 private AppService iperf;
 public IperfAppRunner(List<String> udids, List<String> commands, int runTime) {
 //iperf = new IperfAndroidApp(udids, commands, runTime);
 iperf=(AppService) context.getBean("iperfAppInstance", udids, commands, runTime);
 }
 ...
}

但它似乎没有传递参数..

我得到了这个例外：

Error creating bean with name 'iperfAppInstance' defined in com.airspan.testspan.smarphones.AppConfigurations: Unsatisfied dependency expressed through method 'iperfAppInstance' parameter 0; nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No qualifying bean of type 'java.util.List<java.lang.String>' available: expected at least 1 bean which qualifies as autowire candidate. Dependency annotations: {}
 at org.springframework.beans.factory.support.ConstructorResolver.createArgumentArray(ConstructorResolver.java:749)

所以基本上我正在尝试使用“spring factory”创建一个对象，其中包含一些给我的参数。

可以这样做吗？如果是这样，怎么样？

在春天将参数绑定到bean
