Apakah Anda sedang mengerjakan proyek Spring MVC tingkat Perusahaan? Apakah dengan lebih dari ratusan kelas dan paket? Apakah Anda benar-benar kesulitan tentang cara mendapatkan daftar semua informasi kacang Spring MVC yang dimuat?

Dengan menggunakan cuplikan kode Java di bawah ini, Anda bisa mendapatkan daftar informasi Spring Beans yang dimuat di ujung jari Anda.

Mari kita mulai:

Langkah 1

Prasyarat: Ikuti Cara menggunakan AJAX, jQuery di Spring Web MVC (.jsp) – tutorial sepenuhnya. Pastikan itu bekerja dengan sempurna.

Langkah 2

Buat two new : CrunchifyMain.java dan CrunchifyLoadAllLoadedSpringMVCBean.java

package com . crunchify . controller ;
 
import org . springframework . context . support . ClassPathXmlApplicationContext ;
 
/*

public class CrunchifyMain {
 
public static void main ( String [ ] args ) {
CrunchifyLoadAllLoadedSpringMVCBean bean = new CrunchifyLoadAllLoadedSpringMVCBean ( ) ;
ClassPathXmlApplicationContext ctx = new ClassPathXmlApplicationContext ( new String [ ] { "crunchify-bean.xml" } ) ;
bean . crunchifyLogSpringBeans ( ctx ) ;
}
}

package com . crunchify . controller ;
 
import org . springframework . context . ApplicationContext ;
 
/*

public class CrunchifyLoadAllLoadedSpringMVCBean {
 
public void crunchifyLogSpringBeans ( ApplicationContext ctx ) {
String [ ] crunchifyBeans = ctx . getBeanDefinitionNames ( ) ;
int loadedTotalBeans = ctx . getBeanDefinitionCount ( ) ;
 
String crunchifyFormat = getCrunchifyFormat ( crunchifyBeans ) ;
 
printStatement ( String . format ( "------------- Total Loaded Spring Beans: %d ------------- \n" , loadedTotalBeans ) ) ;
 
int count = 1 ;
for ( String crunchifyBean : crunchifyBeans ) {
Class < ? > beanType = ctx . getType ( crunchifyBean ) ;
Package beanPackage = beanType . getPackage ( ) ;
printStatement ( String . format ( crunchifyFormat , count ++ , crunchifyBean , beanType . getName ( ) , beanPackage ) ) ;
}
}
 
private static void printStatement ( String value ) {
System . out . println ( value ) ;
}
 
private static String getCrunchifyFormat ( String [ ] crunchifyBean ) {
int namespace = betterAlignment ( crunchifyBean ) ;
int typespace = ( crunchifyBean . length < 100 ) ? 2 : 3 ;
return String . format ( "%%%dd: Crunchify Bean Name: %%-%ds \n - Bean Type: %%s \n - Package: %%s \n" , typespace , namespace ) ;
}
 
private static int betterAlignment ( String [ ] crunchifyBean ) {
int length = 0 ;
 
for ( String crunchifyString : crunchifyBean ) {
if ( crunchifyString . length ( ) > length )
length = crunchifyString . length ( ) ;
}
return length ;
}
}

Langkah-3

Buat folder resource sebagai Source Folder di lokasi yang sama dengan folder src .

Buat Folder Sumber di Eclipse - Crunchify

Langkah-4

Buat folder config sebagai Source Folder baru di bawah folder resource . Sama seperti di atas.

Langkah-5

Buat dua file baru:

  1. config.properties di bawah folder config
  2. crunchify-bean.xml file di bawah folder resource

TEAM = CRUNCHIFY . COM
FILE_PATH = config / crunchify . properties

< context : property - placeholder

< / beans >

Langkah-6

Pastikan Anda memiliki struktur proyek di bawah ini.

print-list-of-all-loaded-spring-beans-selama-pemula-mvc-aplikasi-startup Anda

Langkah-7

Jalankan program CrunchifyMain.java .

Anda akan melihat hasil seperti di bawah ini di konsol Eclipse Anda.
