问题 I know there is some similar questions here about how to parse ENUM, how to parse customize JSON structure. But here my question is how to just give a better message when the user submit some JSON with is not as expected. This is the code: @PutMapping public ResponseEntity updateLimitations(@PathVariable("userId") String userId, @RequestBody LimitationParams params) { Limitations limitations = user.getLimitations(); params.getDatasets().forEach(limitations::updateDatasetLimitation); params

问题 I have a JSON structure that incorporates a wrapping level that I don't have in my POJOs. Like so: JSON: { "category1": { "cat1Prop1": "c1p1", "cat1Prop2": "c1p2", "cat1Prop3": "c1p3" }, "category2": { "cat2Prop1": "c2p1", "cat2Prop2": "c2p2" }, "category3": { "cat3Prop1": "c3p1", "cat3Prop2": "c3p2", "cat3Prop3": "c3p3" }, "category4": { "cat4Prop1": "c4p1" } } POJO: public class MyPojo { private String cat1Prop1; private String cat1Prop2; private String cat1Prop3; private String cat2Prop1;

问题 I have a javascript object like follows. { "name": { "type": "text", "onClick": function () { console.log("Hello"); } } } It is stored in string format in Java like. String obj = "{ \"name\": { \"type\": \"text\", \"onClick\": function () { console.log(\"Hello\"); } } }"; I'm trying to figure out a way to read this obj in Java and traverse through the object graph like we can with JSON using Jackson if it didn't have function declaration. Is there any Java library to read/parse a string

问题 I have tried to configure jackson to accept JSON using SNAKE_CASE when using Micronaut, however, it doesn't recognize the property jackson.property-naming-strategy: SNAKE_CASE . 回答1: From Micronaut 1.1.1 application.yml jackson: property-naming-strategy: SNAKE_CASE Before Micronaut 1.1.1 Micronaut constructs ObjectMapper using ObjectMapperFactory that does not set property naming strategy (at least in Micronaut 1.0 GA version, this may change in future releases). The configuration option you

问题 I have a Java class like this and want to convert to JSON using Jackson. Thanks for your help. Java Class public class myClass { String Id; Map<String, Object> optionalData = new LinkedHashMap<String, Object>(); } How to serialization it to JSON using Jackson ObjectMapper ? For example, suppose the optionalData is a Map saving two entries <"type", "book"> and <"year", "2014"> I want the output to be as follow. Please note that the key/value of optionalData could be changed on the fly (so, I

问题 I am using following code to convert my source XML to JSON. However, this code removes any multiple occurrence of child records in source XML and output JSON only contains last child record. How do I get Jackson XML to JSON converter to output all child records in JSON? Code XmlMapper xmlMapper = new XmlMapper(); Map entries = xmlMapper.readValue(new File("source.xml"), LinkedHashMap.class); ObjectMapper jsonMapper = new ObjectMapper(); String json = jsonMapper.writer().writeValueAsString

问题 I have problem with jackson serialization of object by its interface. I have class class Point implements PointView { private String id; private String name; public Point() { } public Point(String id, String name) { this.id = id; this.name = name; } @Override public String getId() { return id; } public String getName() { return name; } } which implements interface PointView { String getId(); } and have class class Map implements MapView { private String id; private String name; private Point
