使用Apache Commons CLI 開發命令行工具

import org.apache.commons.cli.*;
import org.junit.Test;


public class Commons_cli {

    public static void prepare(String[] args) throws Exception {
        // commons-cli命令行參數，需要帶參數值
        Options options = new Options();
        // sql文件路徑
        options.addOption("sql", true, "sql config");
        // 表名稱
        options.addOption("table", true, "table name");

        options.addOption("where", true, "where");
        // 解析命令行參數
        CommandLineParser parser = new DefaultParser();
        CommandLine cl = parser.parse(options, args);
        String sql = cl.getOptionValue("sql");
        String name = cl.getOptionValue("table");
        String where =cl.getOptionValue("where");

        System.out.println("sql : "+sql);
        System.out.println("table : "+name);
        System.out.println("where : "+where);

    }

    @Test
    public void prepare() throws Exception {
        //注，這裏的-sql不是負號的意思，命令行。
        String[] args =  {"-sql","select * from aa",
                "-table","測試",
                "-where","table.id>100"};

        Commons_cli.prepare(args);
    }

}
