fasterxml

I am trying to get the correct JSON for public class MyTestResponse { @XmlElementWrapper(name = "data") @XmlElement(name = "values") public List<String> test = Arrays.asList("Sidney"); } I now get "values": [ "Sidney" ], instead of "data":{ "values": [ "Sidney" ] }, So the wrapper element "data" is not present. I am using com.fasterxml.jackson stack (2.8.6) inside ServiceMix 7 M3. My JSON provider extends com.fasterxml.jackson.jaxrs.json.JacksonJaxbJsonProvider: import com.fasterxml.jackson.databind.AnnotationIntrospector; import com.fasterxml.jackson.databind.MapperFeature; import com

I currently have a project which uses jackson faster xml to serialize/deserialize POJOs to Json using custom serializers and deserializers. From what I understand, the ObjectMapper is thread-safe once it has been created and configured. However, I have noticed when running tests with JMeter that occasionally the following can happen - Thread 1 enters CustomerSerializer and starts to serialize Thread 2 enters CustomSerializer, interuptting Thread 1, and starts to serialize from start to finish Thread 1 resumes, and the last thing being serialized is missing It seems to be that the JsonGenerator

I'm writing a JSON Client for a Server that returns Boolean values as "0" and "1". When I try to run my JSON Client I currently get the following Exception: HttpMessageNotReadableException: Could not read JSON: Can not construct instance of java.lang.Boolean from String value '0': only "true" or "false" recognized So how can I setup FasterXML\Jackson to correctly parse something like: { "SomeServerType" : { "ID" : "12345", "ThisIsABoolean" : "0", "ThisIsABooleanToo" : "1" } } Sample Pojo's: @JsonInclude(JsonInclude.Include.NON_NULL) @JsonPropertyOrder({"someServerType"}) public class myPojo {

基础知识介绍： @RequestBody主要用来接收前端传递给后端的json字符串中的数据的(请求体中的数据的)；GET方式无请求体，所以使用@RequestBody接收数据时，前端不能使用GET方式提交数据，而是用POST方式进行提交。在后端的同一个接收方法里，@RequestBody与@RequestParam()可以同时使用，@RequestBody最多只能有一个，而@RequestParam()可以有多个。 注：一个请求，只有一个RequestBody；一个请求，可以有多个RequestParam。 注：当同时使用@RequestParam（）和@RequestBody时，@RequestParam（）指定的参数可以是普通元素、 数组、集合、对象等等(即:当，@RequestBody 与@RequestParam()可以同时使用时，原SpringMVC接收 参数的机制不变，只不过RequestBody 接收的是请求体里面的数据；而RequestParam接收的是key-value 里面的参数，所以它会被切面进行处理从而可以用普通元素、数组、集合、对象等接收)。 即：如果参数时放在请求体中，传入后台的话，那么后台要用@RequestBody才能接收到；如果不是放在 请求体中的话，那么后台接收前台传过来的参数时，要用@RequestParam来接收，或则形参前
