CQ5如何在自定義插件

Question

我要創建我自己的插件來解析XML和做其他的東西使用外部罐。我已經建立了我自己的捆綁插件，將包含我的分析器類，下面的pom.xml：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> 
<modelVersion>4.0.0</modelVersion> 

<groupId>pl.mycompany.myproject</groupId> 
<artifactId>core</artifactId> 
<version>1.0.0-SNAPSHOT</version> 
<packaging>bundle</packaging> 

<name>core</name> 
<url>http://maven.apache.org</url> 

<build> 
    <plugins> 
     <plugin> 
      <groupId>org.apache.maven.plugins</groupId> 
      <artifactId>maven-compiler-plugin</artifactId> 
      <configuration> 
       <source>1.5</source> 
       <target>1.5</target> 
      </configuration> 
     </plugin> 
     <plugin> 
      <groupId>org.apache.felix</groupId> 
      <artifactId>maven-bundle-plugin</artifactId> 
      <version>1.4.3</version> 
      <extensions>true</extensions> 
      <configuration> 
       <instructions> 
        <Export-Package>pl.mycompany.myproject.page.components.*;version=${pom.version}</Export-Package> 
       </instructions> 
      </configuration>     
     </plugin> 
    </plugins> 
</build> 

<properties> 
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> 
</properties> 

<dependencies> 
    <dependency> 
     <groupId>junit</groupId> 
     <artifactId>junit</artifactId> 
     <version>3.8.1</version> 
     <scope>test</scope> 
    </dependency> 
    <dependency> 
     <groupId>com.day.cq.wcm</groupId> 
     <artifactId>cq-wcm-api</artifactId> 
     <version>5.6.4</version> 
    </dependency> 
    <dependency> 
     <groupId>com.day.cq</groupId> 
     <artifactId>cq-commons</artifactId> 
     <version>5.6.2</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.sling</groupId> 
     <artifactId>org.apache.sling.api</artifactId> 
     <version>2.0.4-incubator</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.sling</groupId> 
     <artifactId>org.apache.sling.commons.json</artifactId> 
     <version>2.0.6</version> 
    </dependency> 
    <dependency> 
     <groupId>org.apache.commons</groupId> 
     <artifactId>commons-lang3</artifactId> 
     <version>3.0.1</version> 
     <scope>provided</scope> 
    </dependency> 
    <dependency> 
     <groupId>xerces</groupId> 
     <artifactId>xercesImpl</artifactId> 
     <version>2.9.0</version> 
     <scope>provided</scope> 
    </dependency> 
</dependencies> 

之後，我想創建類，將解析XML，我想用org.apache .xerces包。

我也創建了一個包含org.apache.xerces罐子其他包和我已經安裝了它，它在http://myhost.com:4502/system/console/bundles是有效的。

當我要聲明的Java類核心插件的DOMParser變量（上面的pom.xml）：}

package pl.mycompany.myproject.page.components; 
import java.util.Date; 
import org.apache.sling.api.resource.Resource; 
import org.apache.xerces.parsers.DOMParser; 
enter code here 
public class EqAndSpecParser { 

private Resource resource; 

public EqAndSpecParser(Resource resource) { 
    this.resource = resource; 
} 

public void checkIfNeedToUpdate(Date lastModifiedDate, String lastGenerationDate, String xmlCode) { 
    try { 
     DOMParser parser = new DOMParser(); 
     parser.parse(xmlCode); 
    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 

public Resource getResource() { 
    return resource; 
} 

public void setResource(Resource resource) { 
    this.resource = resource; 
} 

然後我得到的錯誤/ CRX-快速啓動/日誌/：

DOMParser只是我想要使用的示例類。在項目中，我將需要使用外部罐從其他供應商，這只是POC。主要問題是：如何在CQ5中使用外部罐子？如何將它們安裝到CQ中，所有自定義插件都將使用這些罐子？

當我改變的Xerces依賴於

<dependency> 
    <groupId>xerces</groupId> 
    <artifactId>xercesImpl</artifactId> 
    <version>2.9.0</version> 
    <scope>compile</scope> 
</dependency> 

和我說<Embed-Dependency>xercesImpl;scope=compile</Embed-Dependency> 現在我得到錯誤，如：

Answer 1

包括外部JAR文件到您的包

的這部分你pom.xml中：

<dependency> 
    <groupId>xerces</groupId> 
    <artifactId>xercesImpl</artifactId> 
    <version>2.9.0</version> 
    <scope>provided</scope> 
</dependency> 

的xerces定義爲provided依賴性，例如。一個已經存在於CQ中。如果您要嵌入這種依賴性，範圍更改爲compile和使用<embed-dependency>選項Maven的捆綁插件，如：

<configuration> 
    <instructions> 
     <Export-Package>pl.mycompany.myproject.page.components.*;version=${pom.version}</Export-Package> 
     <Embed-Dependency>xercesImpl;scope=compile</Embed-Dependency> 
    </instructions> 
</configuration>     

此外，這是一個好主意，provided範圍添加到這實際上是所有依賴包括在CQ內（如cq-wcm-api等）。

解析個XML在CQ5

以上是直接回答你的問題（「如何使用外部JAR」）。然而，在這種特殊情況下，我不認爲你應該包括了Xerces庫，因爲它已經在JDK中存在。嘗試刪除了Xerces依賴和使用javax.xml.parsers API：

import javax.xml.parsers.*; 
... 
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance() 
DocumentBuilder builder = factory.newDocumentBuilder() 
builder.parse(new ByteArrayInputStream(xmlCode.getBytes()));
