After few more hours searching I figure out that struts2-rest-plugin is using jacksion for parsing lib And the ObjectMapper will turn Date Object into millionseconds
So struts2-rest-plugin will be first pick after access action when responsing (if no application/json header its will be pass not process) then struts2-json-plugin (using DefaultJsonWriter) in struts2-rest-plugin its first into DefaultContentTypeHandlerManager choosing which ContentTypeHandler to use (in this case the result is JacksonJsonHandler ) Then in JacksonJsonHandler its will use ObjectMapper transfer Date I believe which is reason why change my default date format string into millionseconds and all other ContentTypeHandlers may also cause issue due to also use jacksion lib Is this some kinds of Feature or Bug? If this is bug can someone help me report this issue? 哈哈哈哈 <yangg9...@gmail.com> 於 2023年12月4日 週一 下午8:58寫道： > > HI Thanks for reply > Yes its does change to what i format > but not with if the request with application/json > app still return millionseconds > > and after a day for testing > I finally find out its nothing about struts2-json-plugin > > > its struts2-rest-plugin cause the issue !! > > > if i add this plugin > The Date Object will turn to millionseconds > But I didnt see any word about it at official page > https://struts.apache.org/plugins/rest/ > > here is my action code === > > import java.util.Date; > import com.opensymphony.xwork2.Action; > import com.opensymphony.xwork2.ModelDriven; > public class TmpAction implements ModelDriven<Object> { > private Date model = new Date(); > public Date getModel() { > return model; > } > public void setModel(Date model) { > this.model = model; > } > public String index() { > return Action.SUCCESS; > } > } > > === > here is my struts.xml === > <?xml version="1.0" encoding="UTF-8"?> > <!DOCTYPE struts PUBLIC > "-//Apache Software Foundation//DTD Struts Configuration 2.5//EN" > "http://struts.apache.org/dtds/struts-2.5.dtd";> > > <struts> > <constant name="struts.json.dateformat" value="dd/MM/yyyy" /> > <package name="api" extends="json-default" > namespace="/api"> > <action name="/tmp/*" > class="TmpAction" method="index"> > <result type="json"> > <param name="root">model</param> > </result> > </action> > </package> > </struts> > > ==== > here is part of maven pom.xml the dependencies i have use === > <dependencies> > <dependency> > <groupId>org.apache.struts</groupId> > <artifactId>struts2-core</artifactId> > <version>6.3.0</version> > </dependency> > <dependency> > <groupId>org.apache.struts</groupId> > <artifactId>struts2-json-plugin</artifactId> > <version>6.3.0</version> > </dependency> > <dependency> > <groupId>org.apache.logging.log4j</groupId> > <artifactId>log4j-core</artifactId> > <version>2.17.0</version> > </dependency> > <dependency> > <groupId>org.apache.logging.log4j</groupId> > <artifactId>log4j-api</artifactId> > <version>2.17.0</version> > </dependency> > <dependency> > <groupId>org.apache.struts</groupId> > <artifactId>struts2-rest-plugin</artifactId> > <version>6.3.0</version> > </dependency> > <dependency> > <groupId>com.fasterxml.jackson.dataformat</groupId> > <artifactId>jackson-dataformat-xml</artifactId> > <version>2.16.0</version> > </dependency> > </dependencies> > === > > If still need more information > I can offer github repository to reporduce this issue > Best regards > > Yasser Zamani <yasserzam...@apache.org> 於 2023年12月4日 週一 上午3:24寫道： > > > > Hi, > > > > Thanks for reaching out! > > > > Could you please try setting your desired value to Struts constant > > "struts.json.dateformat" and see if any change happens?
