How to convert JSP to Thymeleaf?

I have problems with Thymeleaf and I don't know how can I do this.

<!-- chart.jsp-->
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<script type="text/javascript">
window.onload = function() {

var dps = [[]];
var chart = new CanvasJS.Chart("chartContainer", {
    animationEnabled: true,
    exportEnabled: true,
    title: {
        text: "Simple Column Chart with Index Labels"
    },
    data: [{
        type: "column", //change type to bar, line, area, pie, etc
        //indexLabel: "{y}", //Shows y value on all Data Points
        indexLabelFontColor: "#5A5757",
        dataPoints: dps[0]
    }]
});

var xValue;
var yValue;
var indexLabel;

<c:forEach items="${dataPointsList}" var="dataPoints" varStatus="loop">
    <c:forEach items="${dataPoints}" var="dataPoint">
        xValue = parseInt("${dataPoint.x}");
        yValue = parseFloat("${dataPoint.y}");
        indexLabel = "${dataPoint.indexLabel}";
        dps[parseInt("${loop.index}")].push({
            x : xValue,
            y : yValue,
            indexLabel : indexLabel
        });
    </c:forEach>
</c:forEach>

chart.render();

}
</script>
</head>
<body>
    <div id="chartContainer" style="height: 370px; width: 100%;"></div>
    <script src="https://canvasjs.com/assets/script/canvasjs.min.js"></script>
</body>
</html>

I have just started using Thymeleaf, and the JSP format does not work for unknown reasons.

This answer does not cover all aspect of converting jsp to thymeleaf but should give you some direction.

  1. You need to create a html file chart.html and save it under src/main/resource/templates

  2. your html should start with

    <!DOCTYPE html> <html xmlns:th="http://www.thymeleaf.org">

  3. Your loop will change from

    <c:forEach items="${dataPointsList}" var="dataPoints" varStatus="loop">

    to th:each="dataPoints:${dataPointsList}"

    and <c:forEach items="${dataPoints}" var="dataPoint">

    to th:each="dataPoint:${dataPoints}"

  4. Take a look at thymeleaf documentation. They have good documentation.
