SpringBoot中Controller接收参数几种方式

第一类：请求路径参数

1、@PathVariable

获取路径参数。即url/{id}这种形式。

2、@RequestParam

获取查询参数。即url?name=这种形式

import com.yeexun.entity.Person;
import org.springframework.web.bind.annotation.*;
import java.util.Map;

@RestController
@RequestMapping("/demo")
public class TestAcceptParamController {

    @GetMapping("/demo/{id}")
    public void demo(@PathVariable(name = "id") String id, @RequestParam(name = "name") String name) {
        System.out.println("id="+id);
        System.out.println("name="+name);
    }

    @PostMapping(path = "/demo1")
    public void demo1(@RequestBody Map person) {
        System.out.println(person.get("name"));
    }

    @PostMapping(path = "/demo2")
    public void demo2(Person person) {
        System.out.println(person.getId()+"-id");
        System.out.println(person.getName()+"-name");
    }
}
