# hhl-threadpool-java 执行调用java中的native方法,jni范调用run方法,ubuntu16环境

###   设置本机 java_home

export JAVA_HOME=/home/root0527/Desktop/openjdk/build/linux-x86_64-normal-server-slowdebug/jdk
export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar
export PATH=$JAVA_HOME/bin:$ANT_HOME/bin:$PATH
### 生成 jni的.h文件 进到MyThread 所在的目录下
javac MyThread.java -h ./jni

### 把com_hhl_jni_thread_MyThread.h 拷贝到c代码目录中
### 配置
CMakeLists.txt include_directories("/home/root0527/Desktop/openjdk/build/linux-x86_64-normal-server-slowdebug/jdk/include") 并且把jni_md.h 文件拷贝到 include目录下

### 在c代码中执行 
/usr/bin/gcc -shared -fpic -I/home/root0527/Desktop/openjdk/build/linux-x86_64-normal-server-slowdebug/jdk/include com_hhl_jni_thread_MyThread.c -o /home/root0527/Desktop/openjdk/build/linux-x86_64-normal-server-slowdebug/jdk/lib/libjni.so

### 设置jdk的vm options 
-Djava.library.path=/home/root0527/Desktop/openjdk/build/linux-x86_64-normal-server-slowdebug/jdk/lib
### 直接运行Application.java的main方法 出现下列情况即为成功
result :
main say: 0
main say: 1
main say: 2
main say: 3
main say: 4
main say: 5
main say: 6
main say: 7
main say: 8
main say: 9
