Print all loaded Spring beans

Question

Is there a way to print all spring beans that load at startup? I am using spring 2.0.

Answer 1

Yes, get ApplicationContext and call .getBeanDefinitionNames()

You can get the context:

• implementation of ApplicationContextAware
• introducing it @Inject / @Autowired (after 2.5)
• use WebApplicationContextUtils.getRequiredWebApplicationContext(..)

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

Answer 2

 public class PrintBeans { @Autowired ApplicationContext applicationContext; public void printBeans() { System.out.println(Arrays.asList(applicationContext.getBeanDefinitionNames())); } } 

Answer 3

Print all the <bean names and its classes:

 package com.javahash.spring.controller; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.context.ApplicationContext; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestParam; @Controller public class HelloWorldController { @Autowired private ApplicationContext applicationContext; @RequestMapping("/hello") public String hello(@RequestParam(value="key", required=false, defaultValue="World") String name, Model model) { String[] beanNames = applicationContext.getBeanDefinitionNames(); for (String beanName : beanNames) { System.out.println(beanName + " : " + applicationContext.getBean(beanName).getClass().toString()); } model.addAttribute("name", name); return "helloworld"; } } 

Answer 4

Using Spring Boot and Drive Starter

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

you can check the endpoint /beans

Answer 5

You can try calling

 org.springframework.beans.factory.ListableBeanFactory.getBeansOfType(Object.class) 

Or enable debug org.springframework for org.springframework .
