Spring in date format conversion

I. BACKGROUND

Building Projects with Ssm+maven

Where the date field in MySQL is a datetime type

The JSON data that the controller returns to the front end is a long type "Date": "1528324651545"

What I need is the YYYY-MM-DD format.

Second, the settlement

1. In the mapper file corresponding to the entity, modify the data type of the column in the Resultmap

1 <Mappernamespace= "Com.ssm.mapper.PeopleMapper">2 3     <Resultmaptype= "Com.ssm.model.people"ID= "Peoplerm">4 ... ..5 6      　　 <result Property= "B_date"column= "Bir_date" javatype= "Java.sql.Date" />7 8 ... ..9 Ten </Resultmap>

2. Add annotations to the Getter method on the corresponding field of the entity class

1 Private Date b_date; 2 3 @DateTimeFormat (pattern= "Yyyy-mm-dd")  5  Public Date getb_date () {7return  b_date; 9 } 　　

2.1 Of course it can be written as follows:

1 Private Date b_date; 2 3 @DateTimeFormat (iso=ISO. Date)5 public Date getb_date () {7return  b_date; 9 } 　　

2.2 When the field in your entity class is of type time, the type of column in Resultmap should be java.sql.Time

Annotations are @datetimeformat (pattern= "HH:mm:ss")

3. Introducing Joda in Maven's Pom.xml

1     <!--Date Time Library -2     <Dependency>3         <groupId>Joda-time</groupId>4         <Artifactid>Joda-time</Artifactid>5         <version>2.3</version>6     </Dependency>

4. In the SPRINGMVC configuration file, add the note driver

1 <mvc:annotation-driven/>
