JNA 调用dll，复杂结构体（结构体包含数组，结构体包含结构体，结构体包含回调函数）

简单dll:https://www.cnblogs.com/ttqi/p/12053715.html

dll调用类：

public class pdtEdsLoadDispatchDeviceInfo {
	public interface CLibbrary extends Library{
		
		String  esdapipatch=AgentGlobals.getXMLProperty("esdapipatch", "C:\\Program Files (x86)\\eastcom\\Eastcom DS 2000(Only SDK)\\sdk\\app\\api\\bin\\EdsApi");
		CLibbrary INSTANCE = (CLibbrary)Native.loadLibrary(esdapipatch, CLibbrary.class);
		int EdsSystemInit(EdsSystemParam_t.ByReference pSysParam);
		
	}
	

}

　　

结构体：

public class EdsSystemParam_t extends Structure{
    public char[] userName=new char[17];
    public char[] userPassword=new char[17];
    public int isLinkOam = 2;
    public WString pResourceConfigFilePath;
    public EdsMsgCallBackProcF lpfnMmModuleProc;
    
    public String bInitGisSnmp = "ETFALSE";
    
    
    
            public static class ByReference extends EdsSystemParam_t implements Structure.ByReference{}
            
           
            public static class ByValue extends  EdsSystemParam_t implements Structure.ByValue{}
            
            @Override
            protected List getFieldOrder() {
                // TODO Auto-generated method stub
                return Arrays.asList(new String[]{"userName","userPassword","isLinkOam","pResourceConfigFilePath",
                    "lpfnSmModuleProc","bInitGisSnmp"});
            }

}

回调函数类：

public class EdsMsgCallBackProcF_class{
	
	public interface EdsMsgCallBackProcF extends StdCallCallback{
		public void MessageHandle(int nCode,String wParam,String lParam);
	}
	public static class MessageHandle_Realize implements EdsMsgCallBackProcF{
		public void MessageHandle(int nCode,String wParam,String lParam) {
　　　　　　　　　　　　　　//回调后内部处理流程
			Log.info("nCode:"+nCode+";wParam:"+wParam+";lParam:"+lParam);
			if(nCode==0x1550){

				Constants.EdsMsgCallBackProcF=true;
				
				Constants.edsRadior.start();
			}else if(nCode==0x1551 || nCode==0x1554){ 
				Constants.EdsMsgCallBackProcF=false;
				Constants.edsRadior.stoptimer();
				//new EdsRadioUserBaseInfoAction_timer().stop();
				//new EdsSystemInitThread().start();
				
			}
		}
	}

}
