Freemarker - Select Option Not Saved

I have a form in my ftl file and one part of this is this select: <$assign value Solution 1: Let's build a common ground: First, create a POJO to hold the information of your form public class Foo { private String bar; // public getter and setter ommitted } Copy Now, in your Spring MVC controller, put the instance you want to bind to into Spring MVC's model. This is done by annotating a method using @ModelAttribute which returns the required instance. Typically, you'll read current values for your form from a database - For the sake of brevity I'm just creating a new model instance here: @Controller public class MyController { @ModelAttribute public Foo readFooFromDB() { // read the current option from the DB or simply create a default option here Foo f = new Foo(); f.setBar("B"); return f; } } Copy Spring will now put the Foo instance into it's model using the name foo. You could change that name by assigning another value to your @ModelAttribute annotation. Next add a @RequestMapping method to your controller, which will forward to your Freemarker View: @Controller public class MyController { .... @RequestMapping("/request/path/") public String process() { return "mytemplate"; } } Copy Finally, in your template use Spring's FreeMarker macros to render a form including your select: <#import "spring.ftl" as spring /> <form action="/request/path/"> <#assign options = { "A": "Option A", "B": "Option B", "C": "Option C" } /> <@spring.formSingleSelect path="foo.bar" options /> <input type="submit" value="Send" /> </form> Copy The form should now render the current value of the your Foo instance ("B" in our case) as the selected option. So far, so good. Last step (the one you were originally asking for): If you submit your form, Spring should bind the submitted bar value to your foo instance. To achieve this, simply add the instance as a parameter to your request method and annotate it again with @ModelAttribute. Note that the name of the parameter is important here and must match the name of the instance in Spring's model - foo in our case: @Controller public class MyController { .... @RequestMapping("/request/path/") public String process( @ModelAttribute Foo foo) { // Binds all submitted request params to matching properties of your foo instance // validate your foo instance and probably save it in a DB return "mytemplate"; } } Copy Voilá Share Post a Comment for "Freemarker - Select Option Not Saved" Top Question How To Do Multiple Hover On List Alright so i wanted to know how i can select multiple items… WebRTC Video Constraints Not Working I'm trying to get a lower resolution from the webcam na… PHP Email & Hyperlinks I'm trying to include a hyperlink in my email but it is… How To Get Some Part Of A Html Body In Php I want to get only some lines of an HTML body and I am usin… HTML Table With Fixed Header And Fixed Leading Columns With Knockout Controls In The Header And First Column I have a HTML table which can be customized by the user: E… JQuery Change Div Background-image With FadeIn/Out I'm trying to create a fadeIn/Out effect on a site I cr… Dropdown Menu On Refresh Changes Javascript I have implemented a navbar uisng bootstrap 4,in which I ha… SEO Friendly 301 Redirect .htm To .aspx I currently have a small-midsize website with .htm extensio… How To Merge And Clean 2 Css Files With Overlapping Selectors/properties?
