Spring MVC 3.0 带注释的控制器无法与 JQuery $.post() 一起使用

在 Spring MVC 控制器中，我尝试访问 JQuery 简单帖子发送的名称。我收到错误在 @RequestMapping* 中找不到 @PathVariable [name] 我哪里出错了？

JQuery Post

$.post("addName.htm",{ name: "John"});

Spring Controller

@RequestMapping(value = "/addName.htm", method = RequestMethod.POST)
public void setAllocations(@PathVariable String name) {

    System.out.println("inside Setting value.... ");
    System.out.println(name);
}

我收到错误

在@RequestMapping 中找不到@PathVariable [name]

原文

I am getting error Could not find @PathVariable [name] in @RequestMapping*
Where i am going wrong?

JQuery Post

$.post("addName.htm",{ name: "John"});

Spring Controller

@RequestMapping(value = "/addName.htm", method = RequestMethod.POST)
public void setAllocations(@PathVariable String name) {

    System.out.println("inside Setting value.... ");
    System.out.println(name);
}

这不是 @PathVariable，您必须使用 @RequestParam 代替。试试这个：

@RequestMapping(value = "/addName.htm", method = RequestMethod.POST)
public void setAllocations(@RequestParam String name) {
    System.out.println(name);
}

这就是区别：

PathVariable: http://yourhost/{name}/addName.html
RequestParam: http://yourhost/addName.html?name={name}

That is not a @PathVariable, you have to use a @RequestParam instead. Try this:

@RequestMapping(value = "/addName.htm", method = RequestMethod.POST)
public void setAllocations(@RequestParam String name) {
    System.out.println(name);
}

This is the difference:

PathVariable: http://yourhost/{name}/addName.html
RequestParam: http://yourhost/addName.html?name={name}

您应该使用 @RequestParam 而不是

@RequestMapping(value = "/addName.htm", method = RequestMethod.POST)
public void setAllocations(@RequestParam String name) {
  System.out.println("inside Setting value.... ");
  System.out.println(name);
}

docs：

@PathVariable 注释参数，用于访问 URI 模板变量。
@RequestParam注解的参数，用于获取具体的Servlet请求参数。

You should use @RequestParam instead of @PathVariable

@RequestMapping(value = "/addName.htm", method = RequestMethod.POST)
public void setAllocations(@RequestParam String name) {
  System.out.println("inside Setting value.... ");
  System.out.println(name);
}

From the docs:

@PathVariable annotated parameters for access to URI template variables.
@RequestParam annotated parameters for access to specific Servlet request parameters.
