JSON的JavaScript对象数组初始化

Question

我需要在JSON对象data下面初始化var p = ${jsonobj};变量，并不完全确定如何在javascript中执行此操作。一个小小的上下文我在JSP页面中使用它并使用Spring MVC从Java控制器传递JSON对象。我测试了它并确保我得到正确的json对象，只是不确定初始化它的javascript语法。这个页面描述了我尝试做什么http://microbuilder.io/blog/2016/01/10/plotting-json-data-with-chart-js.html然而没有说明如何使用变量

<script>
    var ctx = document.getElementById("myChart").getContext('2d');

    var p = ${jsonobj};
    for (var key in p) {
          if (p.hasOwnProperty(key)) {
            console.log(key + " -> " + p[key]);
          }
        }

    var scatterChart = new Chart(ctx, {
        type: 'scatter',
        data: {
            datasets: [{
                label: 'Scatter Dataset',
                data: [{
                    x: -10,
                    y: 0
                }, {
                    x: 0,
                    y: 10
                }, {
                    x: 10,
                    y: 5
                }]
            }]
        },
        options: {
            scales: {
                xAxes: [{
                    type: 'linear',
                    position: 'bottom'
                }]
            }
        }
    });

    </script>

这是传递给jsp的JSON对象

public void testCorrelationTable(List<Test> tests,Model model)
{
    JSONObject obj = new JSONObject();

    System.out.print(obj);
    SampleStatsCalculator sampleStatsCalculator = new SampleStatsCalculator();
    SampleStatsTabulator sampleStatsTabulator = new SampleStatsTabulator(tests);
    TestStatsTabulator testStatsTabulator=new TestStatsTabulator(tests);
    Map<String, Map<String, Test>> sampleTestMap = sampleStatsTabulator.tabulate();
    TestStatsCalculator testStatsCalculator=new TestStatsCalculator(tests,sampleTestMap);
    Map <Test,Stats> testStatsMap= testStatsTabulator.tabulate();

    Map <Test,Stats> testStatsnewMap=testStatsCalculator.calculateCorrelation(testStatsMap);
    TestVisitor visitor=new TestVisitor();

    model.addAttribute("teststatsmap",testStatsMap);
    model.addAttribute("visitor",visitor );
    model.addAttribute("jsonobj", obj);
    for (Entry<Test, Stats> entry : testStatsnewMap.entrySet()) {
        entry.getValue().accept(visitor);

        obj.put(entry.getKey().getTestId(),visitor.getGroupMean());
        System.out.println(entry.getKey().getTestId()+visitor.getGroupMean());
    }
