[spring] How to pass List<String> in post method using Spring MVC?

I need to pass a list of values in the request body of POST method but I get 400: Bad Request error.

Below is my sample code:

@RequestMapping(value = "/saveFruits", method = RequestMethod.POST, 
    consumes = "application/json")
@ResponseBody
public ResultObject saveFruits(@RequestBody List<String> fruits) {
    ...
}

The JSON I am using is: {"fruits":["apple","orange"]}

I had the same use case, You can change your method defination in the following way :

@RequestMapping(value = "/saveFruits", method = RequestMethod.POST, 
    consumes = "application/json")
@ResponseBody
public ResultObject saveFruits(@RequestBody Map<String,List<String>> fruits) {
    ..
}

The only problem is it accepts any key in place of "fruits" but You can easily get rid of a wrapper if it is not big functionality.

You can pass input as ["apple","orange"]if you want to leave the method as it is.

It worked for me with a similar method signature.
