3.测试
测试代码 main.cpp

#include "log4cpp/Category.hh"
#include "log4cpp/PropertyConfigurator.hh"

int main(int argc, char* argv[])
{
    std::string initFileName = "log4cpp.properties";
    log4cpp::PropertyConfigurator::configure(initFileName);

    log4cpp::Category& root = log4cpp::Category::getRoot();

    log4cpp::Category& sub1 = 
        log4cpp::Category::getInstance(std::string("sub1"));

    log4cpp::Category& sub2 = 
        log4cpp::Category::getInstance(std::string("sub1.sub2"));

    root.warn("Storm is coming");

    sub1.debug("Received storm warning");
    sub1.info("Closing all hatches");

    sub2.debug("Hiding solar panels");
    sub2.error("Solar panels are blocked");
    sub2.debug("Applying protective shield");
    sub2.warn("Unfolding protective shield");
    sub2.info("Solar panels are shielded");

    sub1.info("All hatches closed");

    root.info("Ready for storm.");

    log4cpp::Category::shutdown();

    return 0;
}
