<title>Jackson serialized date format problem in spring MVC3-Java-blogjava of the wall grass</title>In spring MVC3, for example, when you do rest, you often use Jason to parse and encounter date formatting problems.
Take a look at the example:

1) For example, there is a Pojo
? Package Com.loiane.model;

Import Java.util.Date;

Import Org.codehaus.jackson.annotate.JsonAutoDetect;

@JsonAutoDetect
@Entity
public class Company {

??? private int id;
??? private double price;
??? Private String Company;
??? private date date;
??? private String size;
??? private byte visible;
}

2) in the controller, return a map
?? Public @ResponseBody map<string,list<company>> View () throws Exception

3) SPIRNG MVC then returns the following JSON characters:
?? {"Total": +, "data": [{"Price": 71.72, "Company": "3m Co", "visible": 1, "id": 1, "size": "Large", "date": 1188615600000},{" Price ": 29.01," Company ":" Aloca
Inc "," visible ": 0," id ": 2," size ":" Medium "," date ": 1185937200000},{" Price ": 83.81," Company ":" Altria Group "
Inc "," visible ": 0," id ": 3," size ":" Large "," date ": 1186110000000
。。。。。。。。。。。。。。。。

4) You can see that the returned time format is not very good

5) So, you can set this:
?? @JsonSerialize (Using=jsondateserializer.class)
Public Date getDate () {
??? return date;
}
Where?? Jsondateserializer is a newly-written class that inherits the Jsonserializer
? Import java.io.IOException; container freight
Import Java.text.SimpleDateFormat;
Import Java.util.Date;

Import Org.codehaus.jackson.JsonGenerator;
Import org.codehaus.jackson.JsonProcessingException;
Import Org.codehaus.jackson.map.JsonSerializer;
Import Org.codehaus.jackson.map.SerializerProvider;
Import org.springframework.stereotype.Component;
@Component
public class Jsondateserializer extends jsonserializer<date>{

??? private static final SimpleDateFormat DateFormat = new SimpleDateFormat ("mm-dd-yyyy");

??? @Override
??? public void serialize (date date, Jsongenerator Gen, Serializerprovider provider)
??????????? Throws IOException, Jsonprocessingexception {

??????? String formatteddate = Dateformat.format (date);

??????? Gen.writestring (formatteddate);
??? }

}

?? Very simple, formatted, this output JSON can be
{"Total": +, "data": [{"Price": 71.72, "Company": "3m Co", "visible": 1, "id": 1, "size": "Large", "date": "09-01-2007"},{" Price ": 29.01," Company ":" Aloca
Inc "," visible ": 0," id ": 2," size ":" Medium "," date ":" 08-01-2007 "},{" price ": 83.81," Company ":" Altria Group
Inc "," visible ": 0," id ": 3," size ":" Large "," date ":" 08-03-2007 "},{" price ": 52.55, ' company ':" American Express Company ", "Visible": 1, "id": 4, "size": "EXTRATP link router wireless signal can transmit how many meters
Large "," date ":" 01-04-2008 "},{" price ": 64.13," Company ":" American International Group
Inc. "," Visible ": 1," id ": 5," size ":" Small "," date ":" 03-04-2008 "},{" price ": 31.61," Company ":" T Inc "," visible " : 0, "id": 6, "size": "Extra
Large "," date ":" 02-01-2008 "},{" price ": 75.43," Company ":" Boeing Co. "," visible ": 1," id ": 7," size ":" Large "," date ":" 01-01-2008 "},{" price ": 67.27," Company ":" Caterpillar
Inc. "," Visible ": 1," id ": 8," size ":" Medium "," date ":" 12-03-2007 "},{" price ": 49.37," Company ":" Citigroup,
Inc. "," Visible ": 1," id ": 9," size ":" Large "," date ":" 11-24-2007 "},{" price ": 40.48," Company ":" e.i. du Pont de Nemours and Company "," visible ": 0," id ": Ten," Size ":" Extra
Large "," date ":" 05-09-2007 "}]," Success ": true}
