What is the method to write code in Java to draw tracks on the map through Baidu Map API?

Baidu Map API provides a wealth of functions that can perform various operations on the map. Among them, drawing trajectories is a common requirement. This article will introduce how to use Java to write code and draw tracks on the map through Baidu Map API.

First of all, you need to prepare the following conditions:

Java development environment: Make sure that the Java development environment has been installed.
Baidu Map Open Platform Account: Register for a Baidu Map Open Platform account, create an application and obtain a developer key (ak).

Next, we will use the Baidu Map JavaScript API and Java back-end code to complete the trajectory drawing.

Step 1: Create the basic web page structure
First, create an HTML file (such as index.html) in your project and add the following basic web page structure:

<!DOCTYPE html>
<html>

<head>
    <meta charset="utf-8">
    <style>
        #map {
            width: 100%;
            height: 500px;
        }
    </style>
</head>

<body>
    <div id="map"></div>

    <script type="text/javascript" src="http://api.map.baidu.com/api?v=3.0&ak=你的开发者密钥"></script>
    <script type="text/javascript" src="http://api.map.baidu.com/library/DrawingManager/1.4/src/DrawingManager.js"></script>

    <script>
        // 在这里编写JavaScript代码
    </script>
</body>

</html>

In this code, we set up a div with the id map for the map container, and introduced Baidu Map's JavaScript API and DrawingManager library.

Step 2: Add code in JavaScript
