Springmvc injects string and time format conversion

The following lists the two time conversions supported by spring
-, method one
1, string to time

 
    @DateTimeFormat(pattern="yyyy-MM-dd HH:mm:ss")
    private Date startTime;

2. The string can also be converted to time. This can be loaded with the controller control layer.

@InitBinder  
public void initBinder(WebDataBinder binder) {  
SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");  
dateFormat.setLenient(false);  
binder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));

3. Time to string
@JsonFormat(pattern="yyyy-MM-dd HH:mm:ss", timezone="GMT+8")
    private Date startTime;
2. Method 2 (serialization)
   JsonSerialize: time is a string Format
   JsonDeserialize: string to time

    @JsonSerialize(using = JsonDateSerializer$19.class)
    @JsonDeserialize(using = JsonDateDeserializer$19.class)
    private Date updateTime;

            JsonProcessingException {
        String formattedDate = formatter.format(value);
        jgen.writeString(formattedDate);
    }
}
