7.商品服務-品牌管理

1.新增品牌管理菜單-上級菜單選擇商品管理

 2.拿到代碼生成器生成的兩個文件放到以下位置

 

 npm run dev運行起來

進入品牌系統發現已經有基本的頁面了

 解決控制檯報錯問題

 

更改權限，讓新增和刪除按鈕一直顯示

 

 

 

 

 給出前端brand.vue的代碼

<template>

3.OSS雲端準備

準備詳見商城項目

 

 

 服務端簽名後直傳--》安全，不要通過本身的服務器也就是前端直傳，服務器只提供相應的簽名數據

4.建立子模塊mall-third-party 整合阿里雲OSS等第三方模塊

 添加pom依賴

 <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alicloud-oss</artifactId>
            <version>2.2.0.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>com.wuyimin.gulimall</groupId>
            <artifactId>gulimall-common</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

添加註冊中心配置中心的文件，新增命名空間third-party.增長配置oss.yml，專門用來處理oss的內容

 

 配置第三方模塊

application.yml

bootstrap.properties

 

 測試上傳

@SpringBootTest
class GulimallThirdPartyApplicationTests {
    @Autowired
    OSSClient ossClient;

    @Test
    void contextLoads() throws FileNotFoundException {
        // 上傳文件流。
        InputStream inputStream = new FileInputStream("C:\\Users\\56548\\Desktop\\1.jpg");
        // 上傳
        ossClient.putObject("gulimall-wuyimin", "1.jpg", inputStream);

        // 關閉OSSClient。
        ossClient.shutdown();
        System.out.println("上傳成功.");
    }
}

5.oss服務端直傳

/**
 * @author wuyimin
 * @create 2021-08-06 14:34
 * @description 簽名信息
 */
@RestController
public class OssController {
    @Autowired
    OSS ossClient;

    @Value("${spring.cloud.alicloud.oss.endpoint}")
    private String endpoint;

    private String bucket="gulimall-wuyimin";
    @Value("${spring.cloud.alicloud.access-key}")
    private String accessId;
    @RequestMapping("/oss/policy")
    public R policy(){
        // https://gulimall-hello.oss-cn-beijing.aliyuncs.com/hahaha.jpg  host的格式爲 bucketname.endpoint
        String host = "https://" + bucket + "." + endpoint;
        // callbackUrl爲 上傳回調服務器的URL，請將下面的IP和Port配置爲您本身的真實信息。
        // String callbackUrl = "http://88.88.88.88:8888";
        String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
        // 用戶上傳文件時指定的前綴。
        String dir = format + "/";
        Map<String, String> respMap = null;
        try {
            long expireTime = 30;
            long expireEndTime = System.currentTimeMillis() + expireTime * 1000;
            Date expiration = new Date(expireEndTime);
            PolicyConditions policyConds = new PolicyConditions();
            policyConds.addConditionItem(PolicyConditions.COND_CONTENT_LENGTH_RANGE, 0, 1048576000);
            policyConds.addConditionItem(MatchMode.StartWith, PolicyConditions.COND_KEY, dir);

            String postPolicy = ossClient.generatePostPolicy(expiration, policyConds);
            byte[] binaryData = postPolicy.getBytes(StandardCharsets.UTF_8);
            String encodedPolicy = BinaryUtil.toBase64String(binaryData);
            String postSignature = ossClient.calculatePostSignature(postPolicy);

            respMap = new LinkedHashMap<String, String>();
            respMap.put("accessid", accessId);
            respMap.put("policy", encodedPolicy);
            respMap.put("signature", postSignature);
            respMap.put("dir", dir);
            respMap.put("host", host);
            respMap.put("expire", String.valueOf(expireEndTime / 1000));
            // respMap.put("expire", formatISO8601Date(expiration));

        } catch (Exception e) {
            // Assert.fail(e.getMessage());
            System.out.println(e.getMessage());
        }

        return R.ok().put("data", respMap);
    }
}

測試簽名返回數據

配置網關

spring:
  cloud:
    gateway:
      routes:

              this.dataForm.name = data.brand.name;
              this.dataForm.logo = data.brand.logo;
              this.dataForm.descript = data.brand.descript;

            }
          });
        }
      });
    }
  }
};
</script>

7.修改oss跨域

 

 

 

點擊上傳文件後

 

 能夠看到oss裏也有了

 8.JSR303校驗註解

product加入依賴

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>

添加notBlank註解

添加@Valid註解

 

/**
     * 保存
     */
    @RequestMapping("/save")
    //@RequiresPermissions("product:brand:save")
    public R save(@Valid @RequestBody BrandEntity brand, BindingResult result){//告訴springMVC這個字段須要校驗,後面緊跟一個參數能夠獲取錯誤信息
        if(result.hasErrors()){
            Map<String ,String> map=new HashMap<>();
            result.getFieldErrors().forEach((item)->{
                String defaultMessage = item.getDefaultMessage();//獲取信息
                String field=item.getField();//獲取錯誤的名字
                map.put(field,defaultMessage);
            });
            return R.error(400,"提交的數據不合法").put("data",map);
        }else{
            brandService.save(brand);
            return R.ok();
        }
    }

用postman發送一個空串，這時候就會報400錯誤

 

 給出完整的校驗Bean

@Data
@TableName("pms_brand")
public class BrandEntity implements Serializable {
    private static final long serialVersionUID = 1L;

    /**
     * 品牌id
     */
    @TableId
    private Long brandId;
    /**
     * 品牌名
     */
    @NotBlank(message = "品牌名不能爲空")//非空，空串也不行
    private String name;
    /**
     * 品牌logo地址
     */
    @NotEmpty
    @URL(message = "logo必須是url地址")//必須是一個url地址
    private String logo;
    /**
     * 介紹
     */
    private String descript;
    /**
     * 顯示狀態[0-不顯示；1-顯示]
     */
    private Integer showStatus;
    /**
     * 檢索首字母
     */
    @NotEmpty
    @Pattern(regexp = "/^[a-zA-z]$/",message = "檢索首字母必須是一個字母")//自定義的規則
    private String firstLetter;
    /**
     * 排序
     */
    @NotNull//integer不能使用notEmpty
    @Min(value = 0,message = "排序必須大於等於0")
    private Integer sort;

}

9.集中異常處理

 咱們以前的方法處理異常很是麻煩，如今來統一處理異常

首先把bindingresult那一段代碼刪掉，不去感知異常，異常就會拋出去

@Slf4j//記錄日誌
//restController+ControllerAdvice
@RestControllerAdvice(basePackages = "com.wuyimin.gulimall.product.controller")
public class GulimallExceptionControllerAdvice {
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public R handleValidException(MethodArgumentNotValidException e){
        log.error("數據校驗出現問題:{},異常類型:{}",e.getMessage(),e.getClass());
        BindingResult bindingResult = e.getBindingResult();//以前的BindingResult屬性
        Map<String,String> map=new HashMap<>();
        bindingResult.getFieldErrors().forEach(item->{
            map.put(item.getField(),item.getDefaultMessage());
        });
        return R.error(400,"數據校驗出現問題").put("data",map);
    }
}

 

 爲了規範枚舉一下各類錯誤狀態碼放在common模塊裏

/**
 * @author wuyimin
 * @create 2021-08-06 16:44
 * @description 錯誤狀態碼枚舉
 */
    /***
     * 錯誤碼和錯誤信息定義類
     * 1. 錯誤碼定義規則爲5爲數字
     * 2. 前兩位表示業務場景，最後三位表示錯誤碼。例如：100001。10:通用 001:系統未知異常
     * 3. 維護錯誤碼後須要維護錯誤描述，將他們定義爲枚舉形式
     * 錯誤碼列表：
     *  10: 通用
     *      001：參數格式校驗
     *  11: 商品
     *  12: 訂單
     *  13: 購物車
     *  14: 物流
     * @author ZSY
     */
    public enum BizCodeEnum {
        /**
         * 系統未知異常
         */
        UNKNOWN_EXCEPTION(10000, "系統未知異常"),
        /**
         * 參數校驗錯誤
         */
        VALID_EXCEPTION(10001, "參數格式校驗失敗");
        private final int code;
        private final String msg;
        BizCodeEnum(int code, String msg) {
            this.code = code;
            this.msg = msg;
        }
        public int getCode() {
            return code;
        }
        public String getMsg() {
            return msg;
        }
    }

更改後的代碼

@Slf4j//記錄日誌
//restController+ControllerAdvice
@RestControllerAdvice(basePackages = "com.wuyimin.gulimall.product.controller")
public class GulimallExceptionControllerAdvice {
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public R handleValidException(MethodArgumentNotValidException e){
        log.error("數據校驗出現問題:{},異常類型:{}",e.getMessage(),e.getClass());
        BindingResult bindingResult = e.getBindingResult();//以前的BindingResult屬性
        Map<String,String> map=new HashMap<>();
        bindingResult.getFieldErrors().forEach(item->{
            map.put(item.getField(),item.getDefaultMessage());
        });
        return R.error(BizCodeEnum.VALID_EXCEPTION.getCode(),BizCodeEnum.VALID_EXCEPTION.getMsg()).put("data",map);
    }

    //其餘任何異常都默認返回error
    @ExceptionHandler(value=Throwable.class)
    public R handleException(Throwable throwable){
        return R.error(BizCodeEnum.UNKNOWN_EXCEPTION.getCode(),BizCodeEnum.UNKNOWN_EXCEPTION.getMsg());
    }
}

    }

測試校驗

 10.分組校驗+自定義校驗註解

entity和controller

 

 

/**
 * 品牌
 * 
 * @author wuyimin
 * @email 565482647@qq.com
 * @date 2021-08-03 11:43:58
 */
@Data
@TableName("pms_brand")
public class BrandEntity implements Serializable {
    private static final long serialVersionUID = 1L;

    /**
     * 品牌id
     */
    @NotNull(message = "修改必須指定品牌id", groups = {UpdateGroup.class})
    @Null(message = "新增不能指定id", groups = {AddGroup.class})
    @TableId
    private Long brandId;
    /**
     * 品牌名
     */
    @NotBlank(message = "品牌名必須提交", groups = {AddGroup.class, UpdateGroup.class})
    private String name;
    /**
     * 品牌logo地址
     */
    @NotBlank(groups = {AddGroup.class})
    @URL(message = "logo必須是一個合法的url地址", groups = {AddGroup.class, UpdateGroup.class})
    private String logo;
    /**
     * 介紹
     */
    private String descript;
    /**
     * 顯示狀態[0-不顯示；1-顯示]
     */
//  @Pattern()
    @NotNull(groups = {AddGroup.class, UpdateStatusGroup.class})
    @ListValue(vals = {0, 1}, groups = {AddGroup.class, UpdateStatusGroup.class})
    private Integer showStatus;
    /**
     * 檢索首字母
     */
    @NotEmpty(groups = {AddGroup.class})
    @Pattern(regexp = "^[a-zA-Z]$", message = "檢索首字母必須是一個字母", groups = {AddGroup.class, UpdateGroup.class})
    private String firstLetter;
    /**
     * 排序
     */
    @NotNull(groups = {AddGroup.class})
    @Min(value = 0, message = "排序必須大於等於0", groups = {AddGroup.class, UpdateGroup.class})
    private Integer sort;

}

    /**
     * 修改
     */
    @RequestMapping("/update")
    //@RequiresPermissions("product:brand:update")
    public R update(@RequestBody BrandEntity brand){
        brandService.updateById(brand);

        return R.ok();
    }

    /**
     * 修改狀態
     */
    @RequestMapping("/update/status")
    //@RequiresPermissions("product:brand:update")
    public R updateStatus(@Validated(UpdateStatusGroup.class)@RequestBody BrandEntity brand){
        brandService.updateById(brand);
        return R.ok();
    }

自定義校驗：

common引入依賴

<!-- https://mvnrepository.com/artifact/javax.validation/validation-api -->
<dependency>
    <groupId>javax.validation</groupId>
    <artifactId>validation-api</artifactId>
    <version>2.0.1.Final</version>
</dependency>

自定義註解

add update updateStatus是三個空接口用於給校驗註解分類

 

 ListValue自定義註解

@Documented
@Constraint(validatedBy = {ListValueConstraintValidator.class})//關聯自定義的校驗器
@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER, TYPE_USE})
@Retention(RUNTIME)
public @interface ListValue {
    String message() default "{com.wuyimin.common.valid.ListValue.message}";//提示信息從ValidationMessages.Properties裏拿到，也能夠直接定義

    Class<?>[] groups() default {};

    Class<? extends Payload>[] payload() default {};

    int[] vals() default {};
}

校驗器 ListValueConstraintValidator

public class ListValueConstraintValidator implements ConstraintValidator<ListValue,Integer> {
    private Set<Integer> set=new HashSet<>();
    //初始化方法 把val值拿到存入集合
    @Override
    public void initialize(ListValue constraintAnnotation) {
        int[] vals=constraintAnnotation.vals();
        for (int val:vals){
            set.add(val);
        }
    }
    //判斷是否校驗成功
    /**
     *
     * @param integer 須要校驗的值
     * @param constraintValidatorContext
     * @return
     */
    @Override
    public boolean isValid(Integer integer, ConstraintValidatorContext constraintValidatorContext) {
        return set.contains(integer);//包含就返回true，不包含就返回false
    }
}
