@PathVariable注解疑问

Question

public class MyController {

Map<Integer,Param> paramMap = new HashMap<>();

@RequestMapping("/getUser/{param}")
public User getUser(@PathVariable Param param){
    return service.doSomething(param);
}

class Param{
  int paramId;
  String ortherField1;
  String ortherField2;
}

}

假如{param}是int,怎么样才能在@PathVariable 处理这步可以直接让传过来的int参数通过从paramMap里拿转为Param类，是什么原理，有什么博客可以推荐一下吗？

Answer 1

获取思路如下

@RequestMapping("/getUser/{paramId}")
public User getUser(@PathVariable Integer paramId){
    Param param = paramMap.get(paramId)
    return service.doSomething(param);
}

关键是paramMap怎么设置值
