JNI 命令行使用

test文件夹下JniTest.java内容

package test;
public class JniTest
    static{
        System.setProperty("java.library.path", "/home/tong.guo/cpp-text-match/bin");
        System.load("/home/tong.guo/cpp-text-match/bin/libXgboostTextMatch.so");
    }
    private native long loadXgboostModel(String modelPath,int threadNum);
    private native float xgboostScore(long pointToHandler,String q1,String q2);
    private native void releaseXgboostModel(long pointToHandler);

    public static void main(String args[]){

        JniTest test=new JniTest();
        long h = test.loadXgboostModel("/home/tong.guo/cpp-text-match/my_df/",10);
        float score = test.xgboostScore(h, "大家好", "大家好吗");
        System.out.println(score);
        test.releaseXgboostModel(h);
    }
}

以UTF-8无BOM格式编码，

在test文件夹平行目录，
先编译：

javac -encoding UTF-8 test/JniTest.java

生成h头文件：

javah -jni -classpath . -encoding UTF-8 test.JniTest
