使用注释配置Spring控制台应用程序 [英] Spring console application configured using annotations

问题描述

我想创建spring控制台应用程序（从maven的命令行运行，例如：mvn exec：java -Dexec.mainClass =package.MainClass）。

I want to create spring console application (running from command line with maven for example: mvn exec:java -Dexec.mainClass="package.MainClass").

是这个应用程序我想有某种服务和dao层。我知道如何做一个Web应用程序，但我没有找到任何信息，如果在一个控制台应用程序（可能与Swing）。

Is this application I want to have some kind of services and dao layers. I know how to do it for a web application but I have not found any information on how to do in case of a console application (leter maybe with Swing).

我'm尝试创建像：

public interface SampleService {
 public String getHelloWorld();
}


@Service
public class SampleServiceImpl implements SampleService {
 public String getHelloWorld() {
  return "HelloWorld from Service!";
 }
}

public class Main {
 @Autowired
 SampleService sampleService;
 public static void main(String [] args) {
  Main main = new Main();
  main.sampleService.getHelloWorld();
 }
}

有可能吗？
我可以在某处找到一个如何做的例子吗？

Is it possible? Can I find somewhere an example of how to do it?

推荐答案

a href =http://static.springsource.org/spring/docs/3.0.x/spring-framework-reference/html/beans.html#beans-factory-instantiation> 3.2.2实例化容器。

Take a look at the Spring Reference, 3.2.2 Instantiating a container.

为了在控制台应用程序中使用Spring，您需要创建一个 ApplicationContext

In order to use Spring in console application you need to create an instance of ApplicationContext and obtain Spring-managed beans from it.

在参考中描述了使用XML配置创建上下文。对于完全基于注释的方法，您可以这样做：

Creating a context using XML config is described in the Reference. For completely annotation-based approach, you can do someting like this:

@Component // Main is a Spring-managed bean too, since it have @Autowired property
public class Main {
    @Autowired SampleService sampleService;
    public static void main(String [] args) {
        ApplicationContext ctx = 
            new AnnotationConfigApplicationContext("package"); // Use annotated beans from the specified package

        Main main = ctx.getBean(Main.class);
        main.sampleService.getHelloWorld();
    }
}
