termux安装java,android下的termux模拟器安装openJDK和运行springboot项目
1、前言
2020年9月份打造好了termux，但是苦于jdk没法安装，只能简单的用ecj(eclipse的java，类似jdk的javac)，但是springboot或者tomcat的项目怎么跑啊?
今天为了做培训演示，找到了termux下的openJDK资源，记录下安装的经过。termux的安装和工具准备参考前一篇android下安装termux模拟器-超便携linux
2、git下载openJDK的安装脚本
ssh登录termux，接着下载termux安装openJDK的脚本
123
git clone https://github.com/MasterDevX/Termux-Java.git
cd Termux-Java
chmod 700 installjava uninstall_java.sh
3、下载openJDK的包(可选)
因为步骤2中installjava会下载一个7、80M的openJDK的tar.gz包，为了减少失败，可以用wget先提前下载对应版本的包
1234
dpkg --print-architecture
aarch64
wget https://github.com/Hax4us/java/releases/download/v8/jdk8_aarch64.tar.gz
调整下步骤2下载的installjava脚本，增加已下载tar.gz的判断
把
1
wget https://github.com/Hax4us/java/releases/download/${tag}/jdk8_${archname}.tar.gz -q
修改成
12345
if [ -f jdk8_${archname}.tar.gz ]; then
ee "\e[32m[*] \e[34mOpen JDK-8 is exist."
else
wget https://github.com/Hax4us/java/releases/download/${tag}/jdk8_${archname}.tar.gz -q
fi
4、安装
看看执行过程有没出错，正常的话应该安装完会出现success提示，如下图
123
bash installjava
Java was successfully installed!
5、测试
也可以参考下图
1234567
java -version
java version "1.8.0_152"
Java(TM) SE Runtime Environment (build 1.8.0_152-b16)
Java HotSpot(TM) 64-Bit Server VM (build 25.152-b16, mixed mode)
echo $JAVA_HOME
/data/data/com.termux/files/usr/share/jdk8
6、上传springboot项目
先添加springboot启动脚本
123456789101112131415161718192021222324252627282930313233343536373839404142434445464748495051525354555657585960616263646566676869707172737475767778798081828384858687
#!/bin/bashSERVICE_HOME="$HOME/Java"
SERVICE_NAME="Z_testCode-0.0.1-SNAPSHOT"
SERVICE_JAR="Z_testCode-0.0.1-SNAPSHOT"
XMS="-Xms256M"
XMX="-Xmx512M"
tmpdir="$HOME/Java/tmp"
cd $SERVICE_HOME
PROG=$SERVICE_JAR
PIDFILE=$SERVICE_HOME/$SERVICE_JAR.pid
JARFILE=$SERVICE_HOME/$SERVICE_JAR.jar
status() {
if [ -f $PIDFILE ]; then
PID=$(cat $PIDFILE)
if [ ! -x /proc/${PID} ]; then
return 1
else
return 0
fi
else
return 1
fi
}
case "$1" in
start)
status
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
echo "-----$PIDFILEexists, process is already running or crashed"
exit 1
fi
##检测 java环境
if [ ! -n $JAVA_HOME ]; then
echo "-----Please check JAVA_HOME!"
echo "-----Exist"
exist 1
else
echo "-----Jave home:$JAVA_HOME"
echo "-----Starting$PROG..."
nohup java -server $XMS $XMX -Djava.io.tmpdir="$tmpdir" -jar $JARFILE > $SERVICE_NAME.log 2>&1 &
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
echo "-----$PROGis started"
echo $! > $PIDFILE
exit 0
else
echo "-----Stopping$PROG"
rm -f $PIDFILE
exit 1
fi
fi
;;
stop)
echo "-----Shutting down$PROG"
ps -ef |grep $SERVICE_NAME|grep -v grep |awk '{print $2}'|xargs kill -9
#kill -9 `cat $PIDFILE`
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
rm -f $PIDFILE
else
echo "-----Failed to stopping$PROG"
fi
;;
status)
status
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
PID=$(cat $PIDFILE)
echo "-----$PROGis running ($PID)"
else
echo "-----$PROGis not running"
fi
;;
restart)
$0 stop
$0 start
;;
*)
echo "Usage:$0{start|stop|restart|status}"
;;
esac
7、启动springboot项目
12
chmod 700 startJar.sh
./startJar.sh start
注意步骤6脚本中有定义tmpdir，因为springboot启动的时候，会往linux的/tmp目录创建临时的缓存目录和文件，在termux下会报目录不存在，需要在classpath下自定义
12
tmpdir="$HOME/Java/tmp"
nohup java -server $XMS $XMX -Djava.io.tmpdir="$tmpdir" -jar $JARFILE > $SERVICE_NAME.log 2>&1 &
核对springboot的启动日志，是否正常
8、测试访问
测试springboot项目提前写好的接口
1234567891011
curl http://127.0.0.1:8090/test/demo
[{"id":1,"account":"test1","password":"password1","name":"张三1","sex":0,"company":"testCompany1"},
{"id":2,"account":"test2","password":"password2","name":"张三2","sex":1,"company":"testCompany2"},
{"id":3,"account":"test3","password":"password3","name":"张三3","sex":0,"company":"testCompany3"},
{"id":4,"account":"test4","password":"password4","name":"张三4","sex":1,"company":"testCompany4"},
{"id":5,"account":"test5","password":"password5","name":"张三5","sex":0,"company":"testCompany5"},
{"id":6,"account":"test6","password":"password6","name":"张三6","sex":1,"company":"testCompany6"},
{"id":7,"account":"test7","password":"password7","name":"张三7","sex":0,"company":"testCompany7"},
{"id":8,"account":"test8","password":"password8","name":"张三8","sex":1,"company":"testCompany8"},
{"id":9,"account":"test9","password":"password9","name":"张三9","sex":0,"company":"testCompany9"},
{"id":10,"account":"test10","password":"password10","name":"张三10","sex":1,"company":"testCompany10"}]
大功告成，现在springboot项目也起来了，访问了termux的mariadb，这些需要在写测试springboot项目提前配置好，这里没做介绍。
