Print all the Spring beans that are loaded

Question

Is there a way to print all the spring beans that are loaded on startup?I am using Spring 2.0.

Answer 1

Yes, get ahold of ApplicationContext and call .getBeanDefinitionNames()

You can get the context by:

• implementing ApplicationContextAware
• injecting it with @Inject / @Autowired (after 2.5)
• use WebApplicationContextUtils.getRequiredWebApplicationContext(..)

Related: You can also detect each bean's registration by registering a BeanPostprocessor bean. It will be notified for each bean.

Answer 2

With Spring Boot and the actuator starter

<dependency>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-actuator</artifactId>
</dependency>

you can check the endpoint /beans
