jQuery Ajax POST request not hitting Spring controller -

-

i unable hit spring controller using jquery ajax post. trying fetch list of string using json response.

my javascript function called when dropdown selected:

function doajaxpost() {      var name = $('#selected_report').val();    alert("post ajax request initiating.... name : " + name);    $.ajax({       type: "post",       url: "/newilr/interfacereportssearch/findentitytypes",      contenttype: "application/json",     data: json.stringify({selectedreport:name}),       datatype: "text",     success: function(response){       if(response.status == "success"){           alert("success");       }else{             alert("failure");       }            },       error: function(e){         alert('error: ' + e);       }     });   }

note 2 of above alerts displayed (post ajax request initiating... , 'error: ' + e))

spring controller handle ajax request: 

@requestmapping (value="/interfacereportssearch/findentitytypes",method=requestmethod.post, produces = "application/json")     public @responsebody jsonresponse adduser(@requestbody string selectedreport , bindingresult result ){      system.out.println("ajax request received! reportname = " + selectedreport);

note above print statement never executed. not see single console output, maybe request not server.

no special beans added servlet condiguration have below 2 added: 

<mvc:annotation-driven /> <context:annotation-config/>

following jars added classpath.

jackson-core-2.2.0 jackson-annotations-2.2.0 jackson-databind-2.2.0

update

solved: changed datatype json

change url attribute of ajax request following:

url: "${pagecontext.request.contextpath}/newilr/interfacereportssearch/findentitytypes",

this should job you.
