400错误请求将嵌套的json对象映射到spring控制器中的java.util.Map时出错(400 Bad request Error in mapping nested json objects

400错误请求将嵌套的json对象映射到spring控制器中的java.util.Map时出错(400 Bad request Error in mapping nested json objects to java.util.Map in spring controller)

嗨，我是春天新手。

我在弹簧控制器中将json对象从angular映射到Map时遇到问题。 我的控制器的定义如下： -

@RequestMapping(value="/PnPanel.go/FlowSheets/data/*", method={RequestMethod.GET, RequestMethod.POST}, consumes="application/json", produces="application/json") public @ResponseBody Map invokeFlowsheets ( HttpServletRequest request, @RequestBody Map<String, Map> req )

我的请求正文看起来像

{"reqParams":"{\"name\":\"sachin\"}","appParams":"{\"name\":\"sachin1\"}","otherInfo":"{\"name\":\"sachin2\"}"}

正如你所看到的，我正在发送嵌套的json对象，我想将它们映射到java.util.Map，但我从spring告诉我请求语法错误时得到400错误。

对不起英语不好以及这样一个愚蠢的问题。

提前致谢。

Hi I am new to spring.

I am facing problem in mapping json object from angular to Map in spring controller. The definition of my controller is as follows :-

@RequestMapping(value="/PnPanel.go/FlowSheets/data/*", method={RequestMethod.GET, RequestMethod.POST}, consumes="application/json", produces="application/json") public @ResponseBody Map invokeFlowsheets ( HttpServletRequest request, @RequestBody Map<String, Map> req )

My Request body looks like

{"reqParams":"{\"name\":\"sachin\"}","appParams":"{\"name\":\"sachin1\"}","otherInfo":"{\"name\":\"sachin2\"}"}

As you can see, I am sending nested json objects and I want to map them into java.util.Map, But I am getting 400 error from spring telling that request was syntactically bad.

Sorry for bad english and for such a silly question.

Thanks in advance.

最满意答案

将您的JSON字符串修改为：

{"reqParams":{"name":"sachin"},"appParams":{"name":"sachin1"},"otherInfo":{"name":"sachin23"}}

请注意， {}未被""包围。

Modify your JSON string into :

{"reqParams":{"name":"sachin"},"appParams":{"name":"sachin1"},"otherInfo":{"name":"sachin23"}}

Notice that {} are not surrounded with "".
