JSONオブジェクトをSpringオブジェクトにマップする方法... AJAXを使用して、JSONオブジェクトをSpringコントローラーに投稿しますが、SpringでそのJSONをJavaのオブジェクトに変換するにはどうすればよいですか
Java コード:
@RequestMapping(method=RequestMethod.POST, value="/employee")
public ModelAndView addEmployee(@RequestBody String body) {
System.out.println("in post: " + body);
Source source = new StreamSource(new StringReader(body));
System.out.println("source: " + source.toString());
//
// how do I turn the JSON String into a Java Object?
//
return new ModelAndView(XML_VIEW_NAME, "object", body);
}
JavaSript/html コード:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

function doAjaxPost() {
var queryString = $('#htmlform').serialize();
alert("doAjaxPost Called :" + queryString +":");
$.ajax({
contentType : "application/json",
dataType : 'json',
type : "POST",
url : contexPath + "/service/employee",
data : queryString, //json serialization (like array.serializeArray() etc)
success : function(data) {
alert("Thanks for submitting. \n\n" + response.result);
// response
},
error : function(request, status, error) {
alert('Error: ' + e);
}
});
}
</script>
