Question

试图将json转换为xml，并从xml转换为jmx文件，但无法转换为jmx文件。有人请帮助使用纯Java代码进行转换。

Answer 1

您可以使用Jackson library来将JSON转换为XML

String jsonString = "" 
        + "{\n \"_links\": {\n" 
        + "    \"individual\": {\n" 
        + "      \"href\": \"/individuals/matching\",\n" 
        + "      \"name\": \"GET\",\n" 
        + "      \"title\": \"Individual Details\"\n" 
        + "    },\n" 
        + "    \"self\": {\n" 
        + "      \"href\": \"/individuals/matching/\"\n" 
        + "    }\n" //
        + "  }\n" //
        + "}";

ObjectMapper objectMapper = new ObjectMapper();
ObjectMapper xmlMapper = new XmlMapper();
JsonNode tree = objectMapper.readTree(jsonString);
String jsonAsXml = xmlMapper.writer().withRootName("RootTagName").writeValueAsString(tree);

您可以使用JMeter API从Java代码构建JMeter测试计划，请查看Five Ways To Launch a JMeter Test without Using the JMeter GUI文章以获取详细说明和示例代码。
