พิมพ์ถั่วสปริงทั้งหมดที่ใส่ไว้

มีวิธีพิมพ์ถั่วสปริงทั้งหมดที่โหลดเมื่อเริ่มต้นหรือไม่ฉันใช้ Spring 2.0

ใช่รับทราบApplicationContextและโทร.getBeanDefinitionNames()

คุณสามารถรับบริบทได้โดย:

• การนำไปใช้ ApplicationContextAware
• ฉีดด้วย@Inject/ @Autowired(หลัง 2.5)
• ใช้ WebApplicationContextUtils.getRequiredWebApplicationContext(..)

ที่เกี่ยวข้อง: คุณยังสามารถตรวจจับการลงทะเบียนของถั่วแต่ละชนิดได้โดยการลงทะเบียนBeanPostprocessorถั่ว จะมีการแจ้งเตือนสำหรับแต่ละถั่ว

public class PrintBeans {
    @Autowired
    ApplicationContext applicationContext;

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

พิมพ์ชื่อ bean และคลาสทั้งหมด:

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";
    }
}

ด้วย Spring Boot และสตาร์ทเตอร์แอคชูเอเตอร์

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

คุณสามารถตรวจสอบจุดสิ้นสุด /beans

applicationContext.getBeanDefinitionNames ()ไม่ได้แสดงถั่วซึ่งมีการลงทะเบียนโดยไม่ต้องเช่น 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);
    }       
}

}

ในขณะที่คุณสามารถมองเห็นในการส่งออก, สภาพแวดล้อม, systemProperties, systemEnvironmentถั่วจะไม่ได้รับการแสดงโดยใช้context.getBeanDefinitionNames ()วิธีการ

สปริงบูต

สำหรับเว็บแอ็พพลิเคชัน Spring Boot คุณสามารถแสดงรายการถั่วทั้งหมดโดยใช้จุดสิ้นสุดด้านล่าง

@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;
}

คุณสามารถลองโทร

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

หรือเปิดการบันทึกการแก้ไขข้อบกพร่องสำหรับorg.springframework. (ในสปริงบูตซึ่งใช้พารามิเตอร์--logging.level.org.springframework=DEBUG)

การใช้ spring-boot-starter-actuatorคุณสามารถเข้าถึงถั่วทั้งหมดได้อย่างง่ายดาย

ขั้นตอนการตั้งค่ามีดังนี้

1. เพิ่มการพึ่งพาลงใน gradle :

เพิ่มการร้องลงในไฟล์ gradle:

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

2. เปิดใช้งานการรักษาความปลอดภัยบน application.properties :

เพิ่มmanagement.security.enabled=falseลงในไฟล์ application.property ของคุณ

1. โทร / ถั่วปลายทาง :

   หลังจากนั้นสปริงการตั้งค่าจะเปิดใช้งานจุดสิ้นสุดที่เกี่ยวข้องกับเมตริกบางส่วน หนึ่งในจุดสิ้นสุดคือ/ beans หลังจากเรียกจุดสิ้นสุดนี้แล้วมันจะให้ไฟล์ json ที่มี bean ทั้งหมดของคุณรวมถึงการพึ่งพาและขอบเขต

นี่คือตัวอย่างไฟล์ 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":[]}]

• Spring Boot Actuator: การตรวจสุขภาพการตรวจสอบการรวบรวมเมตริก

หวังว่านี่จะช่วยคุณได้ ขอบคุณ :)

นี่เป็นอีกวิธีหนึ่งในการพิมพ์ชื่อ bean ทั้งหมดจากบริบทแอปพลิเคชัน spring

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());
}

}
