java - 带有 xml 负载的 Spring Boot Rest Controller

Question

我正在使用使用 application/xml 数据类型的 Spring Boot Rest Controller 创建一个 Rest 服务。发送嵌套 xml 时，它无法解析它。有可能吗？或者我应该继续编写一个新的肥皂界面。

请求负载

<requestData>
    <jvmCount>16</jvmCount>
    <maxAttampts>345</maxAttampts>
    <locationXpath>abd/adfd/bdc</locationXpath>
    <requestPayload>
            <userdetails>
        //variabe user data with different xml structure
            </userdetails>  
    </requestPayload>
</requestData>

Controller

@PostMapping(value = "/soap", consumes=MediaType.APPLICATION_XML_VALUE, 
    produces=MediaType.APPLICATION_XML_VALUE)
@ResponseBody
public ResponseEntity<?> soapServiceClient(@Valid @RequestBody RequestData requestData, Errors errors) throws InterruptedException{
    logger.info(" ==== soapServiceClient - started"+requestData);
}

请求数据pojo

@XmlRootElement
public class RequestData{
    private int jvmCount;
    private String locationXpath;
    private int maxAttampts;
    private String requestPayload;
}

异常

Answer 1

您的应用程序在解析传入的 XML 时遇到问题，因为它认为它是 JSON。也许添加以下内容会有所帮助:

<groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-xml</artifactId>
</dependency>
