您正在抛出 const char * 。 std :: exception 仅捕获 std :: exception 及其所有派生类。因此，为了赶上您的投掷，您应该投掷 std :: runtime_error（ TEST THROW）。或 std :: logic_error（ TEST THROW）;任何合适的选择。 std :: exception 的派生类为在这里列出。

You're throwing a const char*. std::exception only catches std::exception and all derived classes of it. So in order to catch your throw, you should throw std::runtime_error("TEST THROW") instead. Or std::logic_error("TEST THROW"); whatever fits better. The derived classes of std::exception are listed here.
