java call so the file:
Look at the header file:
Determine the class, must be consistent (path comprising: com_tracker_common_business_jobUserTag_contentTags_service_ContentTagsServiceSS )
The method of determining the need to call (e.g. globalInitFull , the return value boolean):
/* DO NOT EDIT THIS FILE - it is machine generated */ #include "jni.h" /* Header for class com_tracker_common_business_jobUserTag_contentTags_service_ContentTagsServiceSS */ #ifndef _Included_com_tracker_common_business_jobUserTag_contentTags_service_ContentTagsServiceSS #define _Included_com_tracker_common_business_jobUserTag_contentTags_service_ContentTagsServiceSS #ifdef __cplusplus extern "C" { #endif /* * Class: com_tracker_common_business_jobUserTag_contentTags_service_ContentTagsServiceSS * Method: globalInit 全局初始化 * Args: inferenceDir jstring Inference的路径如"C:/Inference" * Args: threadCount jint 线程数 * Signature: ()V */ JNIEXPORT jboolean JNICALL Java_com_tracker_common_business_jobUserTag_contentTags_service_ContentTagsServiceSS_globalInitFull (JNIEnv *, jobject, jstring, jint, jstring);
Write the corresponding java class:
package com.tracker.common.business.jobUserTag.contentTags.service; import com.google.common.collect.Maps; import com.tracker.common.business.contentTags.model.entity.RsmDataEntity; import com.tracker.common.data.dao.HBaseDao; import com.tracker.common.utils.StringUtil; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import java.util.List; import java.util.Map; import java.util.concurrent.atomic.AtomicInteger; public class ContentTagsServiceSS { private static final Logger LOG = LoggerFactory.getLogger(ContentTagsServiceSS.class); public native boolean globalInitFull(String initFilePath, int threadNumber, String logpath); public native String getCVLabels(String input); public native void globalCloseFull(String initFilePath, String logpath); private final String EMPTYTAGS = StringUtil.STRING_2 + 0 + StringUtil.STRING_2; public static AtomicInteger errorCount = new AtomicInteger(0); public ContentTagsServiceSS(String initPath,int maxThreadNum,String logPath){ System.load(initPath+"/SemanticLabel.so"); globalInitFull(initPath,maxThreadNum,logPath); } public void close(String initPath,String logPath){ globalCloseFull(initPath,logPath); } }
In this case, to get the relevant class mapping file corresponding to a so.
