springboot 调用 c++生成的so库文件

一、创建c文件

SoTest.h

#pragma once
class SoTest
{
	int Add(int a,int b);
};

SoTest.cpp

#include "SoTest.h"

int SoTest::Add(int a, int b) {
	return a + b;
}

二、创建so文件

/home/ubuntu/projects/SoTest/bin/x64/Debug/libSoTest.so

三、java代码

Maven依赖

<dependency>
	<groupId>net.java.dev.jna</groupId>
	<artifactId>jna</artifactId>
	<version>5.9.0</version>
</dependency>

核心代码

public class SOTest {
    public interface SoTest extends Library {
        static SoTest INSTANCE = Native.load("/home/ubuntu/projects/SoTest/bin/x64/Debug/libSoTest.so", SoTest.class);

        int _ZN6SoTest3AddEii(String x, int a, int b);         // c方法
    }


    public int add(int a, int b) {
        return SoTest.INSTANCE._ZN6SoTest3AddEii("", a, b);
    }

}

测试关键代码

    public static void main(String[] args){
        SOTest soTest = new SOTest();
        soTest.add(1,1);
    }
