[开发测试]关于get和post请求后台怎么接收参数和postman模拟发送参数的格式总结

以两数加法为例展示。
项目结构如图所示：

TestController

@RestController
public class TestController {

    // http://127.0.0.1:8080/test1/1&2
    @RequestMapping("/test1/{a}&{b}")
    public String test(@PathVariable("a") Integer a, @PathVariable("b") Integer b){
        return a + b+"";
    }

    // http://127.0.0.1:8080/test2?a=1&b=2
    @RequestMapping(value = "/test2",params = {"a","b"})
    public String test2(Integer a, Integer b){
        return a + b+"";
    }

    // http://127.0.0.1:8080/test3

    /**
     json
         {
             "a":1,
             "b":2
         }
     */
    @PostMapping(value = "/test3")
    public String test3(@RequestBody Param param){
        return param.getA()+param.getB()+"";
    }

}

Param

public class Param {
    private Integer a;
    private Integer b;

    public Integer getA() {
        return a;
    }

    public void setA(Integer a) {
        this.a = a;
    }

    public Integer getB() {
        return b;
    }

    public void setB(Integer b) {
        this.b = b;
    }
}
