로드 된 모든 Spring Bean을 인쇄하십시오.

시작할 때로드되는 모든 스프링 빈을 인쇄하는 방법이 있습니까? 저는 Spring 2.0을 사용하고 있습니다.

예, ApplicationContext전화를 걸어.getBeanDefinitionNames()

다음을 통해 컨텍스트를 얻을 수 있습니다.

• 구현 ApplicationContextAware
• @Inject/로 주입 @Autowired(2.5 이후)
• 사용하다 WebApplicationContextUtils.getRequiredWebApplicationContext(..)

관련 : Bean을 등록하여 각 Bean의 등록을 감지 할 수도 있습니다 BeanPostprocessor. 각 빈에 대해 알려드립니다.

public class PrintBeans {
    @Autowired
    ApplicationContext applicationContext;

    public void printBeans() {
        System.out.println(Arrays.asList(applicationContext.getBeanDefinitionNames()));
    }
}

모든 빈 이름과 클래스를 인쇄합니다.

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";
    }
}

스프링 부트와 액추에이터 스타터

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

끝점을 확인할 수 있습니다 /beans

applicationContext.getBeanDefinitionNames () 는 BeanDefinition 인스턴스 없이 등록 된 Bean을 표시 하지 않습니다 .

package io.velu.core;

import org.springframework.context.annotation.AnnotationConfigApplicationContext;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;

@Configuration
@ComponentScan
public class Core {

public static void main(String[] args) {
    AnnotationConfigApplicationContext context = new AnnotationConfigApplicationContext(Core.class);
    String[] singletonNames = context.getDefaultListableBeanFactory().getSingletonNames();
    for (String singleton : singletonNames) {
        System.out.println(singleton);
    }       
}

}

콘솔 출력

environment
systemProperties
systemEnvironment
org.springframework.context.annotation.internalConfigurationAnnotationProcessor
org.springframework.context.annotation.ConfigurationClassPostProcessor.importRegistry
org.springframework.context.event.internalEventListenerProcessor
org.springframework.context.event.internalEventListenerFactory
org.springframework.context.annotation.internalAutowiredAnnotationProcessor
org.springframework.context.annotation.internalCommonAnnotationProcessor

applicationEventMulticaster
lifecycleProcessor

출력에서 볼 수 있듯이 환경, systemProperties, systemEnvironment Bean은 context.getBeanDefinitionNames () 메소드를 사용하여 표시 되지 않습니다 .

봄 부팅

스프링 부트 웹 애플리케이션의 경우 아래 엔드 포인트를 사용하여 모든 Bean을 나열 할 수 있습니다.

@RestController
@RequestMapping("/list")
class ExportController {

@Autowired
private ApplicationContext applicationContext;

@GetMapping("/beans")
@ResponseStatus(value = HttpStatus.OK)
String[] registeredBeans() {
    return printBeans();
}

private String[] printBeans() {
    AutowireCapableBeanFactory autowireCapableBeanFactory = applicationContext.getAutowireCapableBeanFactory();
    if (autowireCapableBeanFactory instanceof SingletonBeanRegistry) {
        String[] singletonNames = ((SingletonBeanRegistry) autowireCapableBeanFactory).getSingletonNames();
        for (String singleton : singletonNames) {
            System.out.println(singleton);
        }
        return singletonNames;
    }
    return null;
}

당신은 전화를 시도 할 수 있습니다

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

또는에 대한 디버그 로깅을 설정 org.springframework합니다. (스프링 부트에서는 매개 변수를 사용합니다. --logging.level.org.springframework=DEBUG)

사용 spring-boot-starter-actuator하면 모든 빈에 쉽게 접근 할 수 있습니다.

설정 프로세스는 다음과 같습니다.

1. gradle에 종속성을 추가하십시오 .

gradle 파일에 다음을 추가하십시오.

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

2. application.properties에 대한 보안 활성화 :

management.security.enabled=falseapplication.property 파일에 추가 하십시오.

1. / beans 끝점 호출 :

   그 설정 후 스프링은 일부 메트릭 관련 엔드 포인트를 활성화합니다. 엔드 포인트 중 하나는 / beans입니다. 이 엔드 포인트를 호출 한 후 종속성 및 범위를 포함하여 모든 Bean을 포함하는 json 파일을 제공합니다.

다음은 json 파일의 예입니다.

[{"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":[]}]

자세한 정보는 다음 링크를 참조하십시오.

• Spring Boot Actuator : 상태 확인, 감사, 메트릭 수집
• Spring Boot Actuator : 프로덕션 준비 기능

이것이 당신을 도울 것입니다. 감사 :)

다음은 스프링 애플리케이션 컨텍스트에서 모든 빈 이름을 인쇄하는 또 다른 방법입니다.
