如何啓動OSGI-INF藍圖

我是OSGI-INF藍圖的初學者。我有兩個名爲Account和Currency的類。我現在試圖通過在IntelliJ中按「運行帳戶SHIFT + F10」來啓動我的程序。然後我回來了：如何啓動OSGI-INF藍圖

你好賬戶！

但我想它寫Currency方法toString（）。

帳戶：

package com.domain.subdomain; 

public class Account { 
    private Currency currency; 

    public Account() { 
    } 

    public void setCurrency(Currency currency){ 
     this.currency = currency; 
    } 


    public static void main(String[] args) { 
     System.out.println("Hello Account!"); 

    } 
}

貨幣：

package com.domain.subdomain; 

public class Currency { 
    String country; 
    String isoCode; 
    String unit; 
    String name; 

    double transferPurchase; 
    double transferSell; 
    double transferChange; 
    double transferLast; 
    double transferDelta; 

    double notePurchase; 
    double noteSell; 

    public Currency(){ 

    } 

    public Currency(String country, String isoCode, String unit, String name, double transferPurchase, double transferSell, double transferChange, double transferLast, double transferDelta, double notePurchase, double noteSell) { 
     this.country = country; 
     this.isoCode = isoCode; 
     this.unit = unit; 
     this.name = name; 
     this.transferPurchase = transferPurchase; 
     this.transferSell = transferSell; 
     this.transferChange = transferChange; 
     this.transferLast = transferLast; 
     this.transferDelta = transferDelta; 
     this.notePurchase = notePurchase; 
     this.noteSell = noteSell; 
    } 

    public static void main(String[] args) { 
     System.out.println("Hello Currency!"); 
    } 




    public String getCountry() { 
     return country; 
    } 

    public void setCountry(String country) { 
     this.country = country; 
    } 

    public String getIsoCode() { 
     return isoCode; 
    } 

    public void setIsoCode(String isoCode) { 
     this.isoCode = isoCode; 
    } 

    public String getUnit() { 
     return unit; 
    } 

    public void setUnit(String unit) { 
     this.unit = unit; 
    } 

    public String getName() { 
     return name; 
    } 

    public void setName(String name) { 
     this.name = name; 
    } 

    public double getTransferPurchase() { 
     return transferPurchase; 
    } 

    public void setTransferPurchase(double transferPurchase) { 
     this.transferPurchase = transferPurchase; 
    } 

    public double getTransferSell() { 
     return transferSell; 
    } 

    public void setTransferSell(double transferSell) { 
     this.transferSell = transferSell; 
    } 

    public double getTransferChange() { 
     return transferChange; 
    } 

    public void setTransferChange(double transferChange) { 
     this.transferChange = transferChange; 
    } 

    public double getTransferLast() { 
     return transferLast; 
    } 

    public void setTransferLast(double transferLast) { 
     this.transferLast = transferLast; 
    } 

    public double getTransferDelta() { 
     return transferDelta; 
    } 

    public void setTransferDelta(double transferDelta) { 
     this.transferDelta = transferDelta; 
    } 

    public double getNotePurchase() { 
     return notePurchase; 
    } 

    public void setNotePurchase(double notePurchase) { 
     this.notePurchase = notePurchase; 
    } 

    public double getNoteSell() { 
     return noteSell; 
    } 

    public void setNoteSell(double noteSell) { 
     this.noteSell = noteSell; 
    } 

    @Override 
    public String toString() { 
     return "Currency{" + 
       "country='" + country + '\'' + 
       ", isoCode='" + isoCode + '\'' + 
       ", unit='" + unit + '\'' + 
       ", name='" + name + '\'' + 
       ", transferPurchase=" + transferPurchase + 
       ", transferSell=" + transferSell + 
       ", transferChange=" + transferChange + 
       ", transferLast=" + transferLast + 
       ", transferDelta=" + transferDelta + 
       ", notePurchase=" + notePurchase + 
       ", noteSell=" + noteSell + 
       '}'; 
    } 
}

OSGi包是怎樣的一個插件的您運行內 OSGi容器（JBoss的保險絲，阿帕奇Karaf，Eclipse之後，...）。所以你不需要 a main方法。

當你用Maven構建OSGi包，指定<packaging>bundle</packaging>並添加

<plugin> 
    <groupId>org.apache.felix</groupId> 
    <artifactId>maven-bundle-plugin</artifactId> 
    <extensions>true</extensions> 
    <version>3.3.0</version> 
</plugin>

因爲包JAR有一些額外的頭文件（通過這個插件添加）告訴OSGi容器裝載藍圖文件。

您可以將Blueprint想象成與Spring非常相似的東西：在XML文件中聲明bean和依賴關係。在你的情況下，你只是聲明瞭將被實例化的bean，但是沒有任何代碼「做某事」。

我不知道blueprint-maven-plugin，但我想這是在一個小容器內運行你的包。你如何從maven調用它？

我高度懷疑，運行具有「運行帳戶SHIFT + F10」你只是基本上運行此應用程序作爲一個普通的Java應用程序而不是一個OSGi Blueprint包項目。
