如何使用java Jmeter API按顺序遍历所有jmeter测试计划元素

TestPlan testPlan = new TestPlan();

HashTree testPlanTree = testPlan.getTestPlan();
HashTree threadGroupTree = testPlanTree.get(ThreadGroup.class);

TreeTraverser treeTraverser = new TreeTraverser(threadGroupTree);
treeTraverser.traverse(new HashTreeTraverser() {
    @Override
    public void addNode(Object node, HashTree subTree) {
        // 处理每个元素
        // 可以根据元素的类型进行相应的操作
    }

    @Override
    public void subtractNode() {
        // 忽略
    }
});
