Spring MVC @RequestBody 400 Bad Request 问题? 400 报错

先上Controller代码：

package com.linewell.zzy.admin.action;

import javax.servlet.http.HttpServletRequest;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

import com.linewell.service.mng.IArticleMng;
import com.linewell.zzy.entity.Article;
import com.linewell.zzy.toolkit.Readonly;

@Controller
public class AdminArticleAct {

	@Autowired
	private IArticleMng articleMng;

	@RequestMapping(value = "/admin/article/save.html", method = RequestMethod.POST)
	@ResponseBody
	public String save(@RequestBody
	Article article）
			) {
		System.out.println("INININ");
		return "OK";
	}
}

               alert(textStatus);
			}
		});
		return false;
	});
</script>

js里的serializeObject()代码：

$.fn.serializeObject = function() {
		var o = {};
		var a = this.serializeArray();
		$.each(a, function() {
			if (o[this.name]) {
				if (!o[this.name].push) {
					o[this.name] = [ o[this.name] ];
				}
				o[this.name].push(this.value || '');
			} else {
				o[this.name] = this.value || '';
			}
		});
		return o;
	}

另注：之前搭建框架的时候测试都没问题，现在不知道怎么回事，都搞了一天了
