Spring boot 获取post提交参数的几种方法
前提:
客户端提交header,设置Content-Type类型为:application/json,这一项设置可有可无,但是为了避免出现其他不可预料的问题,事先说明,建议添加这一项请求头header设置。
一、使用@RequestParam
@RequestMapping(value = "/login", method = RequestMethod.POST) public Map<String, Object> login(@RequestParam("username") String username, @RequestParam("password") String password) { Map<String, Object> map = new HashMap<>(); log.info("正在登录,账号 = {},密码 = {}", username, password); return map; }
二、使用Map
@RequestMapping(value = "/login", method = RequestMethod.POST) public Map<String, Object> login(@RequestParam Map<String,Object> params) { Map<String, Object> map = new HashMap<>(); log.info("正在登录,账号 = {},密码 = {}", params.get("username"), params.get("password")); return map; }
三、使用数组
@RequestMapping(value = "/login", method = RequestMethod.POST) public void login(@RequestParam("name") String[] names) { for(String name: names) { System.out.println(name); } }
四、使用自定义对象,建议使用这种方式
@PostMapping("/test") public R test(@Validated @RequestBody Request vo) { ProjectVO projectVO = iProjectService.test(vo); return new R().success(projectVO); }
import org.springframework.http.HttpStatus; import java.io.Serializable; public class R<T> implements Serializable { private Integer status; private String msg; private T data; public R success() { this.status = HttpStatus.OK.value(); this.msg = "OK"; return this; } public R success(Integer status, String message) { this.status = status; this.msg = message; return this; } public R<T> success(T response) { this.status = HttpStatus.OK.value(); this.msg = "OK"; this.data = response; return this; } public R<T> success(Integer status, String message, T response) { this.status = status; this.msg = message; this.data = response; return this; } public R error(String message) { this.status = HttpStatus.INTERNAL_SERVER_ERROR.value(); this.msg = message; return this; } public R error(Integer status, String message) { this.status = status; this.msg = message; return this; } public Integer getStatus() { return status; } public void setStatus(Integer status) { this.status = status; } public String getMsg() { return msg; } public void setMsg(String message) { this.msg = message; } public T getData() { return data; } public void setData(T response) { this.data = response; } }
