I finally figured out how to do this using a JSONBuilder, here’s the code import grails.web.* class JSONSerializer { def target String getJSON() { Closure jsonFormat = { object = { // Set the delegate of buildJSON to ensure that missing methods called thereby are routed to the JSONBuilder buildJSON.delegate = delegate buildJSON(target) } } … Read more
The cleanest way is probably to register a custom DataBinder for possible date formats. import java.beans.PropertyEditorSupport; import java.text.ParseException; import java.text.SimpleDateFormat; import java.util.ArrayList; import java.util.Collections; import java.util.List; public class CustomDateBinder extends PropertyEditorSupport { private final List<String> formats; public CustomDateBinder(List formats) { List<String> formatList = new ArrayList<String>(formats.size()); for (Object format : formats) { formatList.add(format.toString()); // Force String … Read more
The issue is with the use of default JSON converter. Here are your options: 1. Default – all fields, shallow associations a. render blah as JSON 2. Global deep converter – change all JSON converters to use deep association traversal a. grails.converters.json.default.deep = true 3. Named config marshaller using provided or custom converters a. JSON.createNamedConfig(‘deep’){ … Read more
If you need it in an artifact that supports dependency injection, simply inject grailsApplication class MyController { def grailsApplication def myAction = { def bar = grailsApplication.config.my.property } } If you need it in a bean in, say, src/groovy or src/java, wire it up using conf/spring/resources.groovy // src/groovy/com/example/MyBean.groovy class MyBean { def grailsApplication def foo() … Read more
Your configuration is for an h2:mem database. Memory Databases have no tables upon connecting to them, and any & all tables are lost when all the connections are closed. Furthermore, a (named) in memory database is unique to the JVM process that opens it. From the H2 documentation: Sometimes multiple connections to the same in-memory … Read more
If you write the bytes to the output stream, you can treat the controller/action as the source of the image in your GSP. Here’s a quick, untested example: // controller action def displayGraph = { def img // byte array //… response.setHeader(‘Content-length’, img.length) response.contentType=”image/png” // or the appropriate image content type response.outputStream << img response.outputStream.flush() … Read more
It’s a bug, it seems that you can leave it that way and will cause no problem, but if you don’t want to see the message here are some solutions: (Edit: Option 2 seems to work better (see comments in this post)) 1.- singleSession configuration from DataSource.groovy https://jira.grails.org/browse/GRAILS-11198 2.- overriding the H2 dialect: public class … Read more

Grails 3, Grails 4 and Grails 5 The solution is to set maxFileSize and maxRequestSize limits inside your application.yml file (usually placed inside grails-app/conf/). Be sure to have something like this: grails: controllers: upload: maxFileSize: 2000000 maxRequestSize: 2000000 Replace 2000000 with the number of max bytes you want for a file upload and for the … Read more
On Server Side you can use something like this @POST @Path(“/fileupload”) //Your Path or URL to call this service @Consumes(MediaType.MULTIPART_FORM_DATA) public Response uploadFile( @DefaultValue(“true”) @FormDataParam(“enabled”) boolean enabled, @FormDataParam(“file”) InputStream uploadedInputStream, @FormDataParam(“file”) FormDataContentDisposition fileDetail) { //Your local disk path where you want to store the file String uploadedFileLocation = “D://uploadedFiles/” + fileDetail.getFileName(); System.out.println(uploadedFileLocation); // save it … Read more
