The ControllerAdvice annotation has an element/attribute called basePackage which can be set to determine which packages it should scan for Controllers and apply the advices. So, what you can do is to separate those Controllers handling normal requests and those handling AJAX requests into different packages then write 2 Exception Handling Controllers with appropriate ControllerAdvice … Read more
I am not sure if this is the simplest way to go but… You can use the ObjectMapper with a custom printer. The DefaultPrettyPrinter can be used if you modify the indent behaviour. // Create the mapper ObjectMapper mapper = new ObjectMapper(); // Setup a pretty printer with an indenter (indenter has 4 spaces in … Read more
As of Jackson 2.6, there is a way, but it does not work on class attribute annotations, only constructor annotations: /* DOES *NOT* THROW IF bar MISSING */ public class Foo { @JsonProperty(value = “bar”, required = true) public int bar; } /* DOES THROW IF bar MISSING */ public class Foo { public int … Read more
To serialize with Jackson: public String serialize(Object obj, boolean pretty) { ObjectMapper mapper = new ObjectMapper(); mapper.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false); if (pretty) { return mapper.writerWithDefaultPrettyPrinter().writeValueAsString(obj); } return mapper.writeValueAsString(obj); }
There is a new feature in Jackson 2.6 specifically for this case: configure the ObjectMapper to use DeserializationFeature.USE_LONG_FOR_INTS see https://github.com/FasterXML/jackson-databind/issues/504 cowtowncoder pushed a commit that closed this issue on May 19, 2015 Fix #504 and #797
To put the @JsonIgnore to the generated getter method, you can use onMethod = @__( @JsonIgnore ). This will generate the getter with the specific annotation. For more details check http://projectlombok.org/features/GetterSetter.html @Getter @Setter public class User { private userName; @Getter(onMethod = @__( @JsonIgnore )) @Setter private password; }
The correct answer is that you are missing the static keyword on the inner class. Just make sure that the “static” keyword is there. Read http://www.cowtowncoder.com/blog/archives/2010/08/entry_411.html it takes you 3 minutes but make you happy for the rest of the day.
A BeanSerializerModifier will provide you access to the default serialization. Inject a default serializer into the custom serializer public class MyClassSerializer extends JsonSerializer<MyClass> { private final JsonSerializer<Object> defaultSerializer; public MyClassSerializer(JsonSerializer<Object> defaultSerializer) { this.defaultSerializer = checkNotNull(defaultSerializer); } @Override public void serialize(MyClass myclass, JsonGenerator gen, SerializerProvider provider) throws IOException { if (myclass.getSomeProperty() == true) { provider.setAttribute(“special”, true); … Read more
Try adding @RestResource(exported = false) on field answers in class Questionary. According to me, this error occurs because the deserializer expects URIs to fetch the answers from, instead of having the answers nested in the JSON. Adding the annotation tells it to look in JSON instead.
The following works and as per StaxMan’s advice no longer uses the deprecated static collectionType() method. public class SoApp { /** * @param args * @throws Exception */ public static void main(String[] args) throws Exception { System.out.println(“Hello World!”); String s = “[{\”user\”:\”TestCity\”,\”role\”:\”TestCountry\”},{\”user\”:\”TestCity\”,\”role\”:\”TestCountry\”}]”; StringReader sr = new StringReader(“{\”user\”:\”TestCity\”,\”role\”:\”TestCountry\”}”); //UserRole user = mapper.readValue(sr, UserRole.class); mapJsonToObjectList(s,UserRole.class); } protected … Read more
