Jquery 弹簧控制器404在调用POST方法后重新调谐

我有一个从JQuery.post（）调用的Spring控制器。调用时，将调用控制器的方法并返回。但是，在后台，Spring更改URL并调用服务器增益。服务器以404响应

我认为这是对Spring在处理POST方法后试图找到一个视图的回应

如何阻止Spring控制器执行此操作

这是我的Spring控制器：

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.ModelAttribute;
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.ResponseBody;

import java.util.ArrayList;
import java.util.List;

@Controller
@RequestMapping("/person")
public class DataController {

  private List<Person> people = new ArrayList<Person>();

  @RequestMapping(value="put", method = RequestMethod.POST)
  public void addPerson(@ModelAttribute("person") Person person){
    System.out.println(">>>>>>> person: " + person);
    System.out.println(">>>>>>>>> " + person.getFirstName());
    people.add(person);
  }
}

dataSentOK

函数只执行一个

警报（“完成”）

因此，当JQuery方法调用URL时：

http://localhost:8080/jquery/data/person/put

在服务器端，

System.out.println（…）

方法按预期打印数据

然而在Firebug中，服务器发回404

因此，我打开了Spring的日志记录，得到了以下结果：

[01] DispatcherServlet [DEBUG] DispatcherServlet with name 'dispatcherServlet' processing POST request for [/jquery/data/person/put]
[02] AbstractHandlerMethodMapping [DEBUG] Looking up handler method for path /person/put

[13] FrameworkServlet [DEBUG] Successfully completed request
[14] FrameworkServlet [DEBUG] Successfully completed request

响应URL POST请求（/jquery/data/person/put），会找到并调用正确的方法（第1行到第7行），但随后会跳转到第8行的

InternalResourceView

，这会将URL更改为

/jquery/data/person/person/put

，但找不到该方法

我如何阻止Spring试图找到一个视图呢。我想要它做的就是干净利落地返回并完成

感谢您的帮助。

我相信如果您有一个null或void返回类型，Spring将尝试根据请求URL解析视图。我认为这里的正确形式应该是简单地返回OK页面，因为这看起来不是JSON或类似的东西。或者，用@ResponseBody标记它并返回一个空字符串。

问题正如#CodeChimp所建议的，只是我仍然想要一个void返回类型

我将

@ResponseBody

添加到

addPerson

方法中，一切正常：

@RequestMapping(value="put", method = RequestMethod.POST)
**@ResponseBody**
public void addPerson(@ModelAttribute("person") Person person){
  System.out.println(">>>>>>> person: " + person);
  System.out.println(">>>>>>>>> " + person.getFirstName());
  people.add(person);
}

线索来自于。尽管文档不清楚作废退货会发生什么。刚刚试过，效果很好。

谢谢您的回复。答案是添加@ResponseBody。Spring似乎可以很好地处理void返回，我猜void或null返回与空字符串的工作原理相同。Spring只会在响应体中放入任何内容。我发现Spring的人非常聪明，他们在解决方案中倾向于考虑所有可能的角度。
