工作中需要用java调用dll,并获取信息
代码如下:
1 function JavaCall(InS, OutS: PChar): Integer; stdcall; 2 var 3 s: string; 4 begin 5 ShowMessage('您传入的内容:'+InS); 6 s := 'DLL返回内容'; 7 OutS := PChar(s); 8 Result := 999; 9 end;
public interface CLibrary extends Library { CLibrary INSTANCE = (CLibrary) Native.loadLibrary("testdll", CLibrary.class); // 引入库文件 public int JavaCall(String s1, byte[] s2); } public static void main(String[] args) { byte[] aaa = new byte[100]; System.out.println("java call dll result = "+CLibrary.INSTANCE.JavaCall("ttttt", aaa)); System.out.println("aaa="+new String(aaa)); }
最多设置5个标签!
