absrtact: The project often needs to use a conversion between date and string, such as a background date object returned to the front page in JSON form, want to convert to YYYY-MM-DD HH:mm:ss format string, While the front-end page submits the form, the Date field expects to be automatically populated with the background controller method's Date object.The project often requires a conversion between a date and a string, such as when a background date object is returned to the front page in JSON

SPRINGMVC is implemented in the method parameters written to the entity class, and the foreground of the name corresponding can be automatic injection. However, when some integer,long,data types are passed in as empty, they will be error-free.The Integer,long type can be processed in the foreground or in the background using a string type alias;There are two simple ways of data types, one of which is that the string type receives itself for conversionSimpleDateFormat SDF = new SimpleDateFormat (

When validating @datetimeformat annotations with the SpringMVC3 framework, a singular error is encountered, as long as the Date field in the form is entered with a value of the following error:It's confusing. Looked for a long time, also tried a lot of online methods, such as some said the lack of Joda-time-2.3.jar package (later confirmed that this is not the reason).The following snippet of Java code is as follows:@Resourcepublic class Employee {pri

The @DatetimeFormat is to convert a string to date, which is used by the foreground to pass values to the background.@JsonFormat (pattern= "YYYY-MM-DD") converts date to string general background pass value to foreground@JsonFormat will let the time show in 0 zone time. If the direct use will be less than 8 hours to repair change to@JsonFormat (pattern= "Yyyy-mm-dd", timezone= "Gmt+8")Java Entity class time format field annotations

field or name in the foreground form corresponds to it, and it is successfully turned into an entity class, but after the turn, You have to assign the string type to the corresponding date or int type to the appropriate member variable in Java.There is also a way to pass in a string type in the setter method of the corresponding non-string variable of the corresponding entity class, and then convert it with SimpleDateFormat or integer in it.Finally, there is a simple way to add @

Do not know why, the front-end display all the data items are not wrong, only the time that one is very strange, is a series of numbers, and this number in the database can not find ...Then I debug the backend from the service to the controller, and found that the data are not wrong, take is time ah.Baidu later know that the original back in the back of the JSON data, with its own serialization mechanism will turn the time into a long number, as shown above.And then it's going to be a thing to u
