SpringBoot2.0针对请求参数@RequestBody验证统一拦截
针对SpringBoot2中请求参数统一进行拦截处理问题
第一步：建立请求实体类RequetsUserEntity.java
RequetsUserEntity.java
package io.renren.modules.wx.vo;
import java.io.Serializable;
import javax.validation.constraints.NotBlank;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import lombok.Data;
@Data
@ApiModel(description = "RequetsUserEntity")
public class RequetsUserEntity implements Serializable{
private static final long serialVersionUID = 8841143276870083920L;
@ApiModelProperty(value = "appid")
@NotBlank(message="不能为空")
private String appid;
@ApiModelProperty(value = "code")
@NotBlank(message="不能为空")
private String code;
@ApiModelProperty(value = "微信昵称")
@NotBlank(message="不能为空")
private String nickName;
@ApiModelProperty(value = "0未知 1男性 2女性")
@NotBlank(message="不能为空")
private String gender;
@ApiModelProperty(value = "en英文 zh_CN简体中文 zh_TW繁体中文")
private String language;
@ApiModelProperty(value = "用户所在城市")
private String city;
@ApiModelProperty(value = "用户所在省份")
private String province;
@ApiModelProperty(value = "用户所在国家")
private String country;
@ApiModelProperty(value = "用户头像图片的 URL")
private String avatarUrl;
@ApiModelProperty(value = "signature")
@NotBlank(message="不能为空")
private String signature;
@ApiModelProperty(value = "rawData")
@NotBlank(message="不能为空")
private String rawData;
@ApiModelProperty(value = "encryptedData")
@NotBlank(message="不能为空")
private String encryptedData;
@ApiModelProperty(value = "iv")
@NotBlank(message="不能为空")
private String iv;
@ApiModelProperty(value = "1 微信医生端小程序 2微信用户端小程序 3微网站 4手机app 5微信公众号")
@NotBlank(message="不能为空")
private String loginType;
}
第二步：建立Controller进行验证
LoginController.java
package io.renren.modules.wx.controller;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import io.renren.common.utils.R;
import io.renren.modules.wx.vo.RequetsUserEntity;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import lombok.extern.slf4j.Slf4j;
@Api(tags = "微信小程序授权登录接口")
@RestController
@RequestMapping("/wx/user/{appid}")
@Slf4j
public class LoginController {
@ApiOperation("微信小程序授权登录")
@PostMapping("/login")
public R login(@Validated @RequestBody RequetsUserEntity req) {
// TODO 实现自己的业务
log.info("登录成功");
return R.ok("登录成功");
}
}
第三步：设置全局异常进行拦截
RRExceptionHandler.java
package io.renren.common.exception;
import org.apache.shiro.authz.AuthorizationException;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.dao.DuplicateKeyException;
import org.springframework.http.HttpStatus;
import org.springframework.validation.FieldError;
import org.springframework.web.bind.MethodArgumentNotValidException;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import io.renren.common.utils.R;
@RestControllerAdvice
public class RRExceptionHandler {
private Logger logger = LoggerFactory.getLogger(getClass());
@ExceptionHandler(RRException.class)
public R handleRRException(RRException e){
R r = new R();
r.put("code", e.getCode());
r.put("msg", e.getMessage());
return r;
}
@ExceptionHandler(DuplicateKeyException.class)
public R handleDuplicateKeyException(DuplicateKeyException e){
logger.error(e.getMessage(), e);
return R.error("数据库中已存在该记录");
}
@ExceptionHandler(AuthorizationException.class)
public R handleAuthorizationException(AuthorizationException e){
logger.error(e.getMessage(), e);
return R.error("没有权限，请联系管理员授权");
}
@ExceptionHandler(Exception.class)
public R handleException(Exception e){
logger.error(e.getMessage(), e);
return R.error();
}
@ExceptionHandler(MethodArgumentNotValidException.class)
@ResponseStatus(HttpStatus.BAD_REQUEST)
public R validationError(MethodArgumentNotValidException ex) {
FieldError fieldError = ex.getBindingResult().getFieldError();
logger.error(fieldError.getField()+fieldError.getDefaultMessage());
return R.error(9999, fieldError.getField()+fieldError.getDefaultMessage());
}
}
第四步：然后运行SpringBoot项目发送http请求，获取返回信息
第五步：针对R.java类信息如下
R.java
package io.renren.common.utils;
import java.util.HashMap;
import java.util.Map;
public class R extends HashMap {
private static final long serialVersionUID = 1L;
public R() {
put("code", 0);
put("msg", "success");
}
public static R error() {
return error(500, "未知异常，请联系管理员");
}
public static R error(String msg) {
return error(500, msg);
}
public static R error(int code, String msg) {
R r = new R();
r.put("code", code);
r.put("msg", msg);
return r;
}
public static R ok(String msg) {
R r = new R();
r.put("msg", msg);
return r;
}
public static R ok(Map map) {
R r = new R();
r.putAll(map);
return r;
}
public static R ok() {
return new R();
}
@Override
public R put(String key, Object value) {
super.put(key, value);
return this;
}
}
