jackson-databind

问题 I have a type from a third party library ( JSONB from jooq) that I've written a custom serializer/deserializer for: @JsonComponent public class JSONBSerializer extends JsonSerializer<JSONB> { @Override public void serialize(JSONB jsonb, JsonGenerator jsonGenerator, SerializerProvider serializerProvider) throws IOException { jsonGenerator.writeString(jsonb.toString()); } } @JsonComponent public class JSONBDeserializer extends JsonDeserializer<JSONB> { @Override public JSONB deserialize

问题 I have a JSON object with a Boolean property that needs to allow only true or false during the deserialization. Any value different of true and false should throw an exception. How can I do that? e.g.: Valid json: { "id":1, "isValid":true } Invalid json: { "id":1, "isValid":1 } Update I tried what @Michał Ziober proposed and it worked fine. As I'm implementing a Spring application (with Webflux) I just had to configure in a different way. I'm posting here what I did: Create a Configuration

问题 I've generated a Spring Boot web application using Spring Initializr, using embedded Tomcat + Thymeleaf template engine in a macOS Sierra., where I have to parse Json object I have a domain object with this property: @JsonProperty("activationTime") private BigInteger activationTime; But when I parse the object I this error: com.fasterxml.jackson.databind.JsonMappingException: Numeric value (1557587751202) out of range of int at [Source: {"data":[{"id":"18AE62","name":"Device 0018AE62","type":

问题 I have the following Test class: import com.fasterxml.jackson.annotation.JsonIgnoreProperties; import com.fasterxml.jackson.core.JsonGenerationException; import com.fasterxml.jackson.databind.DeserializationFeature; import com.fasterxml.jackson.databind.JsonMappingException; import com.fasterxml.jackson.databind.ObjectMapper; import com.ibm.cio.cloud.cost.model.ElasticResponse; import com.jayway.jsonpath.JsonPath; @JsonIgnoreProperties(ignoreUnknown = true) public class TestJSONPaths {

问题 I want to remove all occurrence of "attributeToRemove" in the following JSON: { "Item994": [ { "attributeToRemove": { "someItem": null }, "types": [ "type194", "type294" ], "p1": "SOS" } ], "Item99": [ { "attributeToRemove": { "someItem": null }, "types": [ "type19", "type29" ], "p1": "SOS" } ] } I tried using removeAll but I keep this Error: Type mismatch: inferred type is (JsonNode!) -> JsonNode! but (JsonNode!) -> Boolean was expected Can anyone suggest how to fix this? Here's my code:

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
