Springboot接收参数
接收参数有三个方法。
1、接收id的方法:
@RestController public class ControllerTest { //在这里读取配置文件 @Autowired private Testconfig testconfig; //访问路径:http://localhost:8080/hello/5 @GetMapping(value = "/hello/{id}") public String hello(@PathVariable("id") Integer id){ return "ID:" + id; } }
2、接收参数:
@RestController public class ControllerTest { //在这里读取配置文件 @Autowired private Testconfig testconfig; //访问路径:http://localhost:8080/hello?id=1551 @GetMapping(value = "/hello") public String hello(@RequestParam("id") Integer id){ return "ID:" + id; } }
也可以这样设置,当不传输参数的时候,默认为5:
//访问路径:http://localhost:8080/hello?id=1551 @GetMapping(value = "/hello") public String hello(@RequestParam(value = "id", required = false, defaultValue = "5") Integer id){ return "ID:" + id; }
