Spring MVC @RequestParam a list of objects
Request parameters are a Multimap of String to String. You cannot pass a complex object as request param.
But if you just pass the username that should work - see how to capture multiple parameters using @RequestParam using spring mvc?
@RequestParam("users") List<String> list
But I think it would be better to just use the request body to pass information.
Spring mvc can support List<Object>, Set<Object> and Map<Object> param, but without @RequestParam.
Take List<Object> as example, if your object is User.java, and it like this:
public class User { private String name; private int age; // getter and setter}And you want pass a param of List<User>, you can use url like this
http://127.0.0.1:8080/list?users[0].name=Alice&users[0].age=26&users[1].name=Bob&users[1].age=16Remember to encode the url, the url after encoded is like this:
http://127.0.0.1:8080/list?users%5B0%5D.name=Alice&users%5B0%5D.age=26&users%5B1%5D.name=Bob&users%5B1%5D.age=16Example of List<Object>, Set<Object> and Map<Object> is displayed in my github.
