Eclipse connects to the MySQL database and gets the table data and stores it in the List collection

Go directly to the code, test method

public ApiResp test(ApiForm form) {
	    IdentifyTotalData temp = new IdentifyTotalData();//创建List<IdentifyData>集合
	    String className = "com.mysql.jdbc.Driver";//Load database driver com.mysql.jdbc.Driver	    
	    String url = "jdbc:mysql://127.0.0.1:3306/jfinal_cms?characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull";//MySQL connection url: jdbc:mysql://{server address}:3306/{database name} ?characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
	    String dbusername = "root"; // database name
	    String password = "123456"; // password
	    
	    try {
	    	Class.forName(className); //Load MYSQL JDBC driver
	    	System.out.println("Success loading Mysql Driver!");
	    } catch (Exception e) {
	    	System.out.print("Error loading Mysql Driver!");
	    	e.printStackTrace ();
	    }
	    try {
	    	Connection connect = DriverManager.getConnection(url,dbusername,password); //The connection URL is jdbc:mysql//server address/database name, and the next two parameters are the login user name and password
	    	System.out.println("Success connect Mysql server!");
	    	Statement stmt = connect.createStatement();
	    	ResultSet rs = stmt.executeQuery("select * from tb_video"); //tb_video is the name of your table
	   
	    	while (rs.next()) { //next field
	    		IdentifyData data = new IdentifyData();//Create IdentifyData object
	    		data.setId(rs.getString(1));//Assign the data object, rs.getString(1) is to get the data of the first column of the current field
	    		data.setIdentifyCharacters(rs.getString(5));
	    		data.setIdentifyCode(rs.getString(5));
	    		data.setIdentifyImageUrl(rs.getString(8));
	    		data.setIdentifyImageLocalUrl(null);
	    		data.setShowCharacters(rs.getString(4));
	    		data.setShowVideoUrl(rs.getString(6));
				data.setShowvideoLocaUrl(null);
				data.setShowImageUrl(rs.getString(8));
				data.setShowIamgeLocalUrl(null);
				data.setVersionID(rs.getString(18));
				temp.lists.add(data);//Store the data object in temp.lists
	    	}
		} catch (Exception e) {
			System.out.print("get data error!"); e.printStackTrace();
		}     
		ApiResp test = new ApiResp(form);//Create an ApiResp object    
		test.setlists(temp.lists);//将temp.lists传给test     
		return test;
