Loading Spring context with specific classloader

How can I go about开发者_StackOverflow社区 loading a Spring context with my own ClassLoader instance?

---

Many Spring Context Loader (for example ClassPathXmlApplicationContext ) are subclass of DefaultResourceLoader.

DefaultResourceLoader has a constructor where you can specify the Classloader and also has a setClassLoader method.

So it is your task to find a constructor of the Spring Context Loader you need, where you can specify the classloader, or just create it, and then use the set to set the classloader you want.

    final ClassLoader properClassLoader = YourClass.class.getClassLoader();

    appContext = new ClassPathXmlApplicationContext("application-context.xml") {

        protected void initBeanDefinitionReader(XmlBeanDefinitionReader reader) {
            super.initBeanDefinitionReader(reader);
            reader.setValidationMode(XmlBeanDefinitionReader.VALIDATION_NONE);
            reader.setBeanClassLoader(properClassLoader);
            setClassLoader(properClassLoader);

The org.springframework.context.support.ClassPathXmlApplicationContext class is here for you.

People who are using spring boot and wants to use custom classloader to create application context can do it like this:

@SpringBootApplication
public class Application
{

public static void main(String[] args) {
  
        
        SpringApplication app =
            new SpringApplication(Application.class);
        
        ResourceLoader resourceLoader = new DefaultResourceLoader();

        YourClassLoaderObject yourClassLoaderObject = new YourClassLoaderObject();

        ((DefaultResourceLoader)resourceLoader).setClassLoader(yourClassLoaderObject);
                
        app.setResourceLoader(resourceLoader);
        
        context = app.run(args);
        
        
       
    }
    
}
