linux 編譯並運行Java文件

因工作需要，調接口時本地訪問不了目標服務器，所以只能在服務器上運行調試。

寫了個腳本來編譯運行。參數輸入Java文件名無后綴

#!/bin/bash
if [ ! -n "$1" ]; then
    echo "Please enter a file name!"
    exit 0
fi
JAVA_FILE=$1.java
LIB_DIR=`pwd`/lib
LIB_JARS=`ls ${LIB_DIR}|grep .jar|awk '{print "'${LIB_DIR}'/"$0}'|tr "\n" ":"`
echo -e "starting compile ${JAVA_FILE}...\c"
#UNIX shell使文件描述符0與進程的標准輸入相結合，文件描述符1與標准輸出相結合，文件描述符2與標准出錯輸出相結合。
#該處的 2>&1 代表着錯誤輸出 輸出到 標准輸出
COMPILE_RESULT=`javac -classpath ${LIB_JARS} ${JAVA_FILE} 2>&1`
if [ -n "$COMPILE_RESULT" ]; then
    echo ""
    echo "$COMPILE_RESULT"
    exit 0
fi
echo "Complie OK!"

echo "Run OK!"
