javacpp调用pdfium的c++动态库

1、.h头文件

2、生成java代码的conf    

PdfiumDocumentConfigure.java
package org.swdc.pdfium.conf;import org.bytedeco.javacpp.annotation.Platform;
import org.bytedeco.javacpp.annotation.Properties;
import org.bytedeco.javacpp.tools.InfoMap;

},inherit = PdfiumViewConfigure.class,target = "org.swdc.pdfium.core.PdfiumDocument",global = "org.swdc.pdfium.core.PdfiumDocument"
)
public class PdfiumDocumentConfigure implements InfoMapper {@Overridepublic void map(InfoMap infoMap) {}
}

PdfiumEditConfigure.java
package org.swdc.pdfium.conf;import org.bytedeco.javacpp.annotation.Platform;
import org.bytedeco.javacpp.annotation.Properties;
import org.bytedeco.javacpp.tools.Info;
import org.bytedeco.javacpp.tools.InfoMap;

},inherit = PdfiumViewConfigure.class,target = "org.swdc.pdfium.core.edit",global = "org.swdc.pdfium.core.PdfiumEdit"
)
public class PdfiumEditConfigure implements InfoMapper {@Overridepublic void map(InfoMap infoMap) {infoMap.put(new Info("FPDF_FILEWRITE_").cppTypes("FPDF_FILEWRITE").translate());// do not add ext private methods.infoMap.put(new Info("priv_fpdf_write_data","priv_fpdf_readJpegBytes","FWriter_","PDFWriter").skip());}
}


PdfiumTextConfigure.java
package org.swdc.pdfium.conf;import org.bytedeco.javacpp.annotation.Platform;
import org.bytedeco.javacpp.annotation.Properties;
import org.bytedeco.javacpp.tools.InfoMap;
import org.bytedeco.javacpp.tools.InfoMapper;@Properties(value = {@Platform(value = "windows-x86_64",include = "fpdf_text.h",link = "pdfium"),@Platform(value = "macosx-x86_64",include = "fpdf_text.h",link = "pdfium")
},inherit = PdfiumViewConfigure.class,target = "org.swdc.pdfium.core.PdfiumText",global = "org.swdc.pdfium.core.PdfiumText"
)
public class PdfiumTextConfigure implements InfoMapper {@Overridepublic void map(InfoMap infoMap) {}
}

 2、工程根pom

<?xml version="1.0" encoding="UTF-8"?>
<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>org.swdc</groupId><artifactId>javacpp-presets</artifactId><version>1.0</version><packaging>pom</packaging><modules><module>live2d</module><module>pdfium</module><module>pdfium4j</module><module>mariadb</module><module>dearimgui</module><module>videoai</module></modules><properties><maven.compiler.source>11</maven.compiler.source><maven.compiler.target>11</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><!--        <javacpp.platform>${os.name}-${os.arch}</javacpp.platform>--><osname>windows</osname><osarch>x86_64</osarch><javacpp.platform>windows-x86_64</javacpp.platform></properties></project>

 

4、执行mvn clean 和 mvn package 详见

6、第二次执行  mvn clean 和 mvn package  时  pdfium的pom文件

<?xml version="1.0" encoding="UTF-8"?>
<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><parent><groupId>org.swdc</groupId><artifactId>javacpp-presets</artifactId><version>1.0</version></parent><artifactId>pdfium</artifactId><version>1.0</version><properties><maven.compiler.source>11</maven.compiler.source><maven.compiler.target>11</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><javacpp.version>1.5.10</javacpp.version><build.skip>false</build.skip></properties><dependencies><!-- https://mvnrepository.com/artifact/org.bytedeco/javacpp --><dependency><groupId>org.bytedeco</groupId><artifactId>javacpp</artifactId><version>${javacpp.version}</version></dependency><!-- https://mvnrepository.com/artifact/org.bytedeco/javacpp --><dependency><groupId>org.bytedeco</groupId><artifactId>javacpp-platform</artifactId><version>${javacpp.version}</version></dependency></dependencies><build><plugins><plugin><groupId>org.bytedeco</groupId><artifactId>javacpp</artifactId><version>${javacpp.version}</version><configuration><encoding>ISO-8859-1</encoding><includePaths><!--                        对应 Platform注解中的 includePath--><!--                        ${basedir} 为当前pom文件所在的项目目录 此处是videoai--><!--                        .h头文件所在目录--><includePath>${basedir}/../platforms/Pdfium/include/</includePath><includePath>${basedir}/../platforms/Pdfium/ext/</includePath></includePaths><linkPaths><linkPath>${basedir}/src/main/resources/org/swdc/pdfium/core/${osname}-${osarch}/</linkPath></linkPaths></configuration><executions><execution><id>javacpp.parser</id><phase>generate-sources</phase><goals><goal>build</goal></goals><configuration><skip>true</skip><!--输出目录生成jnidll的目录  三次 mvn clean mvn package skip都是true--><outputDirectory>${basedir}/src/main/resources/org/swdc/pdfium/core/${osname}-${osarch}/</outputDirectory><classOrPackageName>org.swdc.pdfium.**</classOrPackageName><deleteJniFiles>true</deleteJniFiles></configuration></execution><execution><id>javacpp.compiler</id><phase>process-classes</phase><goals><goal>build</goal></goals><configuration><skip>false</skip><!--  第一二次mvn clean mvn package skip都是false 第三次是true--><!--     第一次mvn clean mvn package生成java代码的目录   -->

7、第三次执行 mvn clean 和 mvn package  时  pdfium的pom文件

<?xml version="1.0" encoding="UTF-8"?>
<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><parent><groupId>org.swdc</groupId><artifactId>javacpp-presets</artifactId><version>1.0</version></parent><artifactId>pdfium</artifactId><version>1.0</version><properties><maven.compiler.source>11</maven.compiler.source><maven.compiler.target>11</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><javacpp.version>1.5.10</javacpp.version><build.skip>false</build.skip></properties><dependencies><!-- https://mvnrepository.com/artifact/org.bytedeco/javacpp --><dependency><groupId>org.bytedeco</groupId><artifactId>javacpp</artifactId><version>${javacpp.version}</version></dependency><!-- https://mvnrepository.com/artifact/org.bytedeco/javacpp --><dependency><groupId>org.bytedeco</groupId><artifactId>javacpp-platform</artifactId><version>${javacpp.version}</version></dependency></dependencies><build><plugins><plugin><groupId>org.bytedeco</groupId><artifactId>javacpp</artifactId><version>${javacpp.version}</version><configuration><encoding>ISO-8859-1</encoding><includePaths><!--                        对应 Platform注解中的 includePath--><!--                        ${basedir} 为当前pom文件所在的项目目录 此处是videoai--><!--                        .h头文件所在目录--><includePath>${basedir}/../platforms/Pdfium/include/</includePath><includePath>${basedir}/../platforms/Pdfium/ext/</includePath></includePaths><linkPaths><linkPath>${basedir}/src/main/resources/org/swdc/pdfium/core/${osname}-${osarch}/</linkPath></linkPaths></configuration><executions><execution><id>javacpp.parser</id><phase>generate-sources</phase><goals><goal>build</goal></goals><configuration><skip>true</skip><!--输出目录生成jnidll的目录  三次 mvn clean mvn package skip都是true--><outputDirectory>${basedir}/src/main/resources/org/swdc/pdfium/core/${osname}-${osarch}/</outputDirectory><classOrPackageName>org.swdc.pdfium.**</classOrPackageName><deleteJniFiles>true</deleteJniFiles></configuration></execution><execution><id>javacpp.compiler</id><phase>process-classes</phase><goals><goal>build</goal></goals><configuration><skip>true</skip><!--  第一二次mvn clean mvn package skip都是false 第三次是true--><!--     第一次mvn clean mvn package生成java代码的目录   -->
<!--                            <outputDirectory>${basedir}/src/main/java/-->
<!--                            </outputDirectory>--><!--     第二次mvn clean mvn package生成jnidll的目录   --><outputDirectory>${basedir}/src/main/resources/org/swdc/pdfium/core/${osname}-${osarch}/</outputDirectory><deleteJniFiles>true</deleteJniFiles><classOrPackageName>org.swdc.pdfium.**</classOrPackageName><copyLibs>false</copyLibs></configuration></execution></executions></plugin></plugins></build></project>

8、此时生成的pdfium-1.0.jar 便可以实现javacpp调用

9、详细代码连接如下

通过百度网盘分享的文件：javacpp-demo.zip
链接：https://pan.baidu.com/s/1ZDvctWkGG1rL1683xS8Srw?pwd=2e5y 
提取码：2e5y

10、总结如下 

第一步 mvn clean  mvn package 是生成java 代码

第二步 mvn clean  mvn package 是生成jni动态库

第三步 mvn clean  mvn package 是生成可以使用的jar
