Wydrukuj wszystkie załadowane ziarna wiosenne

Czy istnieje sposób na wydrukowanie wszystkich ziaren wiosennych, które są ładowane podczas uruchamiania? Używam Spring 2.0.

Tak, odbierz ApplicationContexti zadzwoń.getBeanDefinitionNames()

Możesz uzyskać kontekst poprzez:

• realizowanie ApplicationContextAware
• wstrzyknięcie go z @Inject/ @Autowired(po 2,5)
• posługiwać się WebApplicationContextUtils.getRequiredWebApplicationContext(..)

Powiązane: rejestrację każdego ziarna można również wykryć, rejestrując BeanPostprocessorziarno. Zostanie powiadomiony o każdym ziarnie.

public class PrintBeans {
    @Autowired
    ApplicationContext applicationContext;

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

Wydrukuj wszystkie nazwy ziaren i ich klasy:

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";
    }
}

Ze sprężyną rozruchową i rozrusznikiem siłownika

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

możesz sprawdzić punkt końcowy /beans

applicationContext.getBeanDefinitionNames () czy nie pokazać ziarna, które są zarejestrowane bez instancji BeanDefinition.

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);
    }       
}

}

Wyjście konsoli

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
messageSource
applicationEventMulticaster
lifecycleProcessor

Jak widać w danych wyjściowych, komponenty bean environment, systemProperties, systemEnvironment nie zostaną wyświetlone przy użyciu funkcji context.getBeanDefinitionNames () metody .

Spring Boot

W przypadku aplikacji internetowych uruchamianych wiosną wszystkie komponenty bean można wyświetlić za pomocą poniższego punktu końcowego.

@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;
}

}

Możesz spróbować zadzwonić

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

Lub włącz rejestrowanie debugowania dla org.springframework. (W butach wiosennych używa się parametru --logging.level.org.springframework=DEBUG)

Za pomocą spring-boot-starter-actuatormożna łatwo uzyskać dostęp do wszystkich fasoli.

Oto proces konfiguracji:

1. Dodaj zależność do gradle :

Dodaj poniżej do pliku gradle:

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

2. Włącz zabezpieczenia w application.properties :

Dodaj management.security.enabled=falsedo pliku application.property

1. punkt końcowy połączenia / fasoli :

   Po tej konfiguracji wiosna włączy niektóre punkty końcowe związane z metrykami. Jednym z jego punktów końcowych jest / fasola Po wywołaniu tych punktów końcowych dostarczy plik json, który zawiera wszystkie komponenty bean, w tym jego zależności i zakres.

Oto przykładowy plik json:

[{"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":[]}]

Mam nadzieję, że to ci pomoże. Dzięki :)

Oto inny sposób wydrukowania wszystkich nazw ziaren z kontekstu aplikacji wiosennej:

import java.util.Arrays;
import java.util.concurrent.atomic.AtomicInteger;

import org.apache.logging.log4j.LogManager;
import org.apache.logging.log4j.Logger;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.ConfigurableApplicationContext;

/***********************************************************************************************************
 * Java File: MainApplication.java
 * Description: Main class to run the application.
 * 
 ***********************************************************************************************************/

@SpringBootApplication
public class MainApplication {

private static final Logger logger = LogManager.getLogger(MainApplication.class);

public static void main(String[] args) 
{
    final ConfigurableApplicationContext context = SpringApplication.run(MainApplication.class, args);

    final AtomicInteger counter = new AtomicInteger(0);
    logger.info("**************** START: Total Bean Objects: {} ******************", context.getBeanDefinitionCount());

    Arrays.asList(context.getBeanDefinitionNames())
    .forEach(beanName -> {
        logger.info("{}) Bean Name: {} ", counter.incrementAndGet(), beanName);
    });

    logger.info("**************** END: Total Bean: {} ******************", context.getBeanDefinitionCount());
}

}
