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

Using spring-boot-starter-actuator you can easily access all bean.

Here is the setup process:

1. Add dependency into gradle:

Add bellow into gradle file:

compile("org.springframework.boot:spring-boot-starter-actuator")

2. Enable security on application.properties:

Add management.security.enabled=false into your application.property file

1. call /beans endpoint:

   After that setup spring will enable some metrics related endpoints. One of its endpoint is /beans After calling this endpoints it will provide a json file that contains all of your bean including it's dependency and scope.

Here is an example json file:

[{"context":"application:8442","parent":null,"beans":[{"bean":"beanName","aliases":[],"scope":"singleton","type":"packageName$$4b46c703","resource":"null","dependencies":["environment","beanName1","beanName2"]},{"bean":"org.springframework.boot.autoconfigure.internalCachingMetadataReaderFactory","aliases":[],"scope":"singleton","type":"org.springframework.core.type.classreading.CachingMetadataReaderFactory","resource":"null","dependencies":[]}]
