jackson-databind

问题 I have a JSON array of the form: [ [ 1232324343, "A", "B", 3333, "E" ], [ 12345424343, "N", "M", 3133, "R" ] ] I want to map each element of the parent array to a POJO using the Jackson library. I tried this: ABC abc = new ABC(); ObjectMapper mapper = new ObjectMapper(); JsonNode jsonNode = mapper.readTree(data).get("results"); if (jsonNode.isArray()) { for (JsonNode node : jsonNode) { String nodeContent = mapper.writeValueAsString(node); abc = mapper.readValue(nodeContent,ABC.class); System

问题 When I make a json request to a spring boot backend, Jackson is automatically converting numbers to strings. Is there a way to prevent that? For example: JSON { "numberAsString": 123 } JAVA private String numberAsString; after binding json value to the java field numberAsString is equal to "123" . i need to prevent this automatic conversion and need to throw some kind of a exception when this happens. 来源： https://stackoverflow.com/questions/56678885/disable-the-number-to-string-automatic

问题 Is there any way to configure Jackson in Spring Boot so I can HTML escape all the values in the @RequestBody? I have tried with serializers but as far as I know they are defined to a specific class. I would need a filter which process all the values sent in the JSON and escape them with something like: StringEscapeUtils.escapeHtml4(value) Thanks 回答1: How about creating an XSS filter and invoke it in RequestInterceptor public class XSSRequestWrapper extends HttpServletRequestWrapper { public
