I am using POST MAN CLIENT of GOOGLE CHROME TO SEND articleName and articleId AS HEADER application/json.What things I needed to change in my controller and library as well as in my spring servlet.xml?My controller is as follows.
public class ArticleController {
#Autowired
private ArticleService articleService;
Article article = new Article();
Long articleId = article.getArticleId();
#RequestMapping(value = "/save", method = RequestMethod.POST)
public Article saveArticle(#ModelAttribute Article article,
BindingResult bindingresult) {
int a = articleService.addArticle(article);
if (a == 1) {
return new ModelAndView("success");
} else {
return new ModelAndView("error");
}
}

Answer 1

I assume what you want is to return JSON easily from Spring.
To do that you need Jackson dependency:
<dependency>
<groupId>org.codehaus.jackson</groupId>
<artifactId>jackson-mapper-asl</artifactId>
<version>1.7.1</version>
</dependency>
When you have it,
you can annotate your method with #ResponseBody annotation just like this:
public #ResponseBody Article saveArticle(#ModelAttribute Article article,
BindingResult bindingresult) {
....
}
Such a method will return JSONified Article object in response.
