C++使用JNI调用Java函数获取JavaClassObject数组

public class JavaClass {
    public static JavaClassObject[] getJavaClassObjects() {
        // 在这里实现获取JavaClassObject数组的逻辑
        return null;
    }
}

javah -jni JavaClass

#include <jni.h>
#include "JavaClass.h"

JNIEXPORT jobjectArray JNICALL Java_com_example_MainActivity_getJavaClassObjects(JNIEnv *env, jobject obj) {
    // 获取JavaClass类
    jclass javaClass = env->FindClass("com/example/JavaClass");
    
    // 获取getJavaClassObjects方法
    jmethodID getJavaClassObjectsMethod = env->GetStaticMethodID(javaClass, "getJavaClassObjects", "()[Lcom/example/JavaClassObject;");
    
    // 调用getJavaClassObjects方法
    jobjectArray javaClassObjects = (jobjectArray)env->CallStaticObjectMethod(javaClass, getJavaClassObjectsMethod);
    
    return javaClassObjects;
}

g++ -shared -o libnative.so -I"$JAVA_HOME/include" -I"$JAVA_HOME/include/linux" Native.cpp

public class MainActivity {
    static {
        System.loadLibrary("native");
    }
    
    public native JavaClassObject[] getJavaClassObjects();
    
    public static void main(String[] args) {
        MainActivity mainActivity = new MainActivity();
        JavaClassObject[] javaClassObjects = mainActivity.getJavaClassObjects();
        
        // 处理获取到的JavaClassObject数组
    }
}
