java - JNI：程序显示“AWT-EventQueue-0”java.lang.UnsatisfiedLinkError：client.dll：找不到指定的过程”

Question

我有一个 java 程序，它需要一个用 C++ 编译的库。为此，我生成了 JNI 头文件，然后使用 JNI 将我的 c++ 应用程序库编译为 .dll。目前，我遇到了一个问题，即链接完成后，我无法运行我的 java 程序。它在下面显示以下错误：

public app.IncClientTester(java.lang.String,java.lang.String,java.lang.String)
Exception in thread "AWT-EventQueue-0" java.lang.UnsatisfiedLinkError: IncClient.dll: The specified 
procedure could not be found

这是我的 Java 代码：

public class IncClientTester extends Tester {
public IncClientTester(String h, String u, String p) {
    super(h, u, p);
    // TODO Auto-generated constructor stub
}

public native boolean getComponentStatus(int status, int ver);

public native boolean getDeviceThresholdHit();

static {
    System.loadLibrary("IncClient");
}
}

这是我的 C++ 代码：

JNIEXPORT jboolean JNICALL Java_app_IncClientTester_getComponentStatus (JNIEnv*, jobject, jint applstat, jint applversion) { 
     // some code in here
     return status // boolean
}

这是我的 C++ Cmakelist.txt：

project(Inc)

cmake_policy(SET CMP0015 NEW)
cmake_policy(SET CMP0081 NEW)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -pthread -std=c++0x")

    src-gen/v1/commonapi/IncSomeIPDeployment.cpp
)
target_link_libraries(IncClient CommonAPI CommonAPI-SomeIP vsomeip3)

有人可以帮助我指导我如何解决这个问题。
