Freemarker - Select Option Not Saved

I have a form in my ftl file and one part of this is this select: <$assign valueSolution 1: Let's build a common ground:First, create a POJO to hold the information of your formpublicclassFoo{ privateString bar; // public getter and setter ommitted } CopyNow, 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:@ControllerpublicclassMyController { @ModelAttributepublic Foo readFooFromDB() { // read the current option from the DB or simply create a default option hereFoof=newFoo(); f.setBar("B"); return f; } } CopySpring 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:@ControllerpublicclassMyController { .... @RequestMapping("/request/path/") publicStringprocess() { return"mytemplate"; } } CopyFinally, 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> CopyThe 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:@ControllerpublicclassMyController { .... @RequestMapping("/request/path/") publicStringprocess(@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 DBreturn"mytemplate"; } } CopyVoilá Share Post a Comment for "Freemarker - Select Option Not Saved" Top Question Can't Get Text Highlighted When Multiple Tags Are Present So I am trying to highlight text by selecting it and clicki… JQuery Val Is Undefined?
