} Below is a static util class that can be used to check the list of beans available in the application context

ExampleConfigurationTest.java

package com.mugil.org.utils;

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Service;

@Service
public class SpringUtils implements ApplicationContextAware {
    private static ApplicationContext ctx;

    @Override
    public void setApplicationContext(ApplicationContext appContext)
            throws BeansException {
        ctx = appContext;
    }

    public static ApplicationContext getApplicationContext() {
        return ctx;
    }
}

SomeRandomClass.java

class SomeRandomClass
{
    @Autowired
    SpringUtils springUtils;

    
    public void getBeans() 
    {  
        String[] beans = springUtils.getApplicationContext().getBeanDefinitionNames();
        Arrays.sort(beans);
        for (String bean : beans)
        {
            System.out.println(bean + " of Type :: " + springUtils.getApplicationContext().getBean(bean).getClass());
        }
}
}

Output

DBConfig of Type :: class com.mugil.org.configs.DBConfig$$EnhancerBySpringCGLIB$$d32ee4ac
dbProperties of Type :: class com.mugil.org.configs.DBProperties
spring.datasource-com.mugil.org.configs.DBProperties of Type :: class com.mugil.org.configs.DBProperties
springUtils of Type :: class com.mugil.org.utils.SpringUtils

In case if you don’t want to create a separate class and wanted to access beans in the context you can implement the ApplicationContextAware interface and specify the for loop in overridden setApplicationContext method.
