我正在用c ++编写一个java本机库,并在本机lib本身中使用异常处理,但是一旦抛出异常,库就会崩溃.这是我的简单测试程序,当我从Java测试中调用它时,它会在抛出异常时立即崩溃.catch块无法正常工作.我想念的任何想法.谢谢.

#include "Test.h"
#include <iostream>

JNIEXPORT void JNICALL Java_Test_helloWorld(JNIEnv *, jobject)
{
    std::cout<<"Hello World";
    try {
        throw 1;
    }
    catch(int )
    {
        std::cout<<" catch int block"<<std::endl;
    }
    catch(...)
    {
        std::cout<<" catch block"<<std::endl;
    }
}

编译和链接:

g++ -m64 -fPIC -fexceptions -c test.cpp
g++ -shared -m64 -Wl,-soname,libtest.so -Wl,-shared-libgcc test.o -o libtest.so

$ java  -d64 -Djava.library.path=/home/vkumar/projects/test -cp $CLASSPATH Test
