先把SpringBoot 项目用 MAVEN打成jar包

@RestController
public class PublicApi {

    @RequestMapping("test")
    public ApiResponse<Integer> testApi() {
        //DhScalePluNet 为DLL文件名 这是获取相对目录的方式,绝对目录可以自行百度
        CLibrary instance= Native.loadLibrary("DhScalePluNet" , CLibrary.class);
        int i = instance.dhSendPluDefault();
        if(i != 0 ){
            ApiResponse<Integer> result = new ApiResponse<>(ErrorCode.ERROR);
            result.setResult(i);
            return result;
        }
        return new ApiResponse<>(ErrorCode.NO_ERROR);
    }


    @RequestMapping("test")
    public ApiResponse<Integer> testApi() {
        String pa = new File(".").getAbsolutePath();
        pa = pa.substring(0, pa.length()-1);
        pa = pa + "DhScalePluNet";
        pa = pa.replaceAll("/", "\\\\");
        log.info("全路径: " + pa); //全路径 此路径为exe执行时所在文件路径,应用打包后,dll|ini等文件将与exe文件同级目录

        CLibrary instance= Native.loadLibrary(pa , CLibrary.class);
        int i = instance.dhSendPluDefault();
        if(i != 0 ){
            ApiResponse<Integer> result = new ApiResponse<>(ErrorCode.ERROR);
            result.setResult(i);
            return result;
        }
        return new ApiResponse<>(ErrorCode.NO_ERROR);
    }
}
