Where do I put my XML beans in a Spring Boot application?
提问by David Newcomb
I'm getting back into Spring (currently v4). It's all wonderful now with @SpringBootApplicationand the other annotations but all the documentation seems to forget to mention how I define other beans in XML!
我要回到 Spring（目前是 v4）。现在有了@SpringBootApplication其他注释，一切都很棒，但所有文档似乎都忘记提及我如何在 XML 中定义其他 bean！
For example I'd like to create an "SFTP Session Factory" as defined at: http://docs.spring.io/spring-integration/reference/html/sftp.html
例如，我想创建一个“SFTP 会话工厂”，定义如下：http: //docs.spring.io/spring-integration/reference/html/sftp.html
There is a nice bit of XML to define the bean but where on earth do I put it and how do I link it in? Previously I did a:
有一个很好的 XML 来定义 bean，但是我到底把它放在哪里以及如何链接它？以前我做了一个：
ApplicationContext context = new ClassPathXmlApplicationContext(
"classpath:applicationContext.xml");
to specify the file name and location but now that I'm trying to use:
指定文件名和位置，但现在我正在尝试使用：
ApplicationContext ctx = SpringApplication.run(Application.class);
Where do I put the XML file? Is there a magic spring name to call it?
我把 XML 文件放在哪里？有没有神奇的春天名字来称呼它？

As long as you're starting with a base @Configurationclass to begin with, which it maybe sounds like you are with @SpringBootApplication, you can use the @ImportResourceannotation to include an XML configuration file as well.
只要您从一个基@Configuration类开始（听起来好像是这样）@SpringBootApplication，您就可以使用@ImportResource注释来包含一个 XML 配置文件。
@SpringBootApplication
@ImportResource("classpath:spring-sftp-config.xml")
public class SpringConfiguration {
//
}

You also can translate the XML config to a Java config. In your case it would look like:
您还可以将 XML 配置转换为 Java 配置。在你的情况下，它看起来像：
@Bean
public DefaultSftpSessionFactory sftpSessionFactory() {
DefaultSftpSessionFactory factory = new DefaultSftpSessionFactory();
factory.setHost("localhost");
factory.setPrivateKey(new ClassPathResource("classpath:META-INF/keys/sftpTest"));
factory.setPrivateKeyPassphrase("springIntegration");
factory.setPort(22);
factory.setUser("kermit");
return factory;
}
You can put this method in the class with the @SpringBootApplicationannotation.
您可以将此方法放在带有@SpringBootApplication注释的类中。

Spring boot ideal concept is avoid xml file. but if you want to keep xml bean, you can just add @ImportResource("classPath:beanFileName.xml").
Spring boot 的理想概念是避免 xml 文件。但是如果你想保留 xml bean，你可以添加@ImportResource("classPath:beanFileName.xml").
I would recommend remove the spring-sftp-config.xmlfile. And, convert this file to spring annotation based bean. So, whatever class has been created as bean. Just write @Serviceor @Componentannotation before class name. for example:
我建议删除该spring-sftp-config.xml文件。并且，将此文件转换为基于 spring 注释的 bean。因此，任何类都已创建为 bean。只需在类名前写上@Service或@Component注释即可。例如：
XML based:
基于 XML：
<bean ID="id name" class="com.example.Employee">
Annotation:
注解：
@Service or @Component
class Employee{
}
And, add @ComponentScan("Give the package name"). This is the best approach.
并且，添加@ComponentScan("Give the package name"). 这是最好的方法。
