How to automatically parse String @RequestBody as json
提问by riddy
I have an endpoint which should read a string value as body.
我有一个端点，它应该读取一个字符串值作为正文。
@RestController
public class EndpointsController {
@RequestMapping( method = RequestMethod.PUT, value = "api/{myId}/name", consumes= MediaType.APPLICATION_JSON )
public String updateName( @PathVariable( MY_ID ) String myId, @RequestBody String name) {
//will be: "new name"
//instead of : newname
return myId;
}
}
My problem is, that client will call this with "new name" which is correct IMHO but the server reads this with the quotes, because it does not handle the string as a json object. How can I tell Hymanson to parse the string as well (same way than it does with Pojos)?
我的问题是，该客户端将使用“新名称”调用它，恕我直言，这是正确的，但服务器用引号读取它，因为它不会将字符串作为 json 对象处理。我怎样才能告诉 Hymanson 解析字符串（与 Pojos 的解析方式相同）？

If you're using Hymanson as your JSON parser, you can simply declare your parameter with the type TextNode. This is the Hymanson type representing JSON strings.
如果您使用 Hymanson 作为 JSON 解析器，则只需使用类型声明参数即可TextNode。这是表示 JSON 字符串的 Hymanson 类型。
public String updateName(@PathVariable(MY_ID) String myId, @RequestBody TextNode name) {
You can then use its asTextmethod to retrieve its text value.
然后您可以使用它的asText方法来检索其文本值。
