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;
}
}
