Java 利用JavaCPP 调用算法

配置so 文件存放路径
[root@arch2 ~]# cat /etc/ld.so.conf.d/so.conf 
/opt/app/tools/so/

从新调用ldconfig 命令
ldconfig

• 配置pom 文件

配置文件当中需要主要的几点

    false
    ${project.build.sourceDirectory}                         	             com.jacdong.preset.* 

	java			
    -jar ./libs/javacpp-1.5.jar -Xcompiler -g -Xcompiler -ggdb -nodelete -d target/classes/linux-x86_64 -Xcompiler -I${env.JAVA_HOME}/include -Xcompiler -I${env.JAVA_HOME}/include/linux -Xcompiler -fvisibility=default -Xcompiler -rdynamic -Xcompiler -std=c++11 -classpath target/classes com.jacdong.wrapper.SingleStationIono 

@Properties(target = "com.jacdong.wrapper.JavaCPPTestTmp",
value = {@Platform(include = {"javacpp.h"},
        compiler = "cpp11")})
public class JavacppMapper implements InfoMapper{

	public void map(InfoMap infoMap) {
        infoMap.put(new Info().cppNames("_stdcall").skip())
        .put();
}

}

在利用javacpp 的时候，经常会出现找不到so 文件的情况，这个时候，大家可以把so 文件copy 到/usr/lib 目录下，然后更改相应的权限。
