7.商品服务-品牌管理

1.新增品牌管理菜单-上级菜单选择商品管理

 2.拿到代码生成器生成的两个文件放到如下位置

 

 npm run dev运行起来

进入品牌系统发现已经有基本的页面了

 解决控制台报错问题

 

更改权限,让新增和删除按钮一直显示

 

 

 

 

 给出前端brand.vue的代码

<template>

3.OSS云端准备

准备详见商城项目

 

 

 服务端签名后直传--》安全,不要经过自己的服务器也就是前端直传,服务器只提供相应的签名数据

4.创建子模块mall-third-party 整合阿里云OSS等第三方模块

 添加pom依赖

 <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>

添加注册中心配置中心的文件,新增命名空间third-party.增加配置oss.yml,专门用来处理oss的内容

 

 配置第三方模块

application.yml

bootstrap.properties

 

 测试上传

@SpringBootTest
class GulimallThirdPartyApplicationTests {
    @Autowired
    OSSClient ossClient;

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

        // 关闭OSSClient。
        ossClient.shutdown();
        System.out.println("上传成功.");
    }
}

5.oss服务端直传

/**
 * @author wuyimin
 * @create 2021-08-06 14:34
 * @description 签名信息
 */
@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的格式为 bucketname.endpoint
        String host = "https://" + bucket + "." + endpoint;
        // callbackUrl为 上传回调服务器的URL,请将下面的IP和Port配置为您自己的真实信息。
        // String callbackUrl = "http://88.88.88.88:8888";
        String format = new SimpleDateFormat("yyyy-MM-dd").format(new Date());
        // 用户上传文件时指定的前缀。
        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);
    }
}

测试签名返回数据

配置网关

spring:
  cloud:
    gateway:
      routes:
        #商品的路由
        #localhost:88/api/product/category/list/tree--->localhost:10000/product....
        #优先级比下面的哪个路由要高所以要放在上面,不然会被截断
        - id: product_route
          uri: lb://gulimall-product
          predicates:
            - Path=/api/product/**
          filters:
            - RewritePath=/api/(?<segment>.*),/$\{segment}
#第三方路由配置
        - id: third_party_route
          uri: lb://gulimall-third-party
          predicates:
            - Path=/api/thirdparty/**
          filters:
            - RewritePath=/api/thirdparty/(?<segment>.*),/$\{segment}

        - id: admin_route
          #lb表示负载均衡
          uri: lb://renren-fast
          #规定前端项目必须带有一个api前缀
          #原来验证码的uri ...localhost:88/api/captcha.jpg
          #应该改成的uri ...localhost:88/renrenfast/captcha.jpg
          predicates:
            - Path=/api/**
          filters:
            - RewritePath=/api/(?<segment>.*),/renren-fast/$\{segment}

6.前端

增加文件夹

 

 需要把这个地址改掉,单文件和多文件都要改

      this.visible = true;
      this.$nextTick(() => {
        this.$refs["dataForm"].resetFields();
        if (this.dataForm.brandId) {
          this.$http({
            url: this.$http.adornUrl(

            ),
            method: "get",
            params: this.$http.adornParams()
          }).then(({data}) => {
            if (data && data.code === 0) {
              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

 

 

 

点击上传文件后

 

 可以看到oss里也有了

 8.JSR303校验注解

product加入依赖

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

添加notBlank注解

添加@Valid注解

 

/**
     * 保存
     */
    @RequestMapping("/save")
    //@RequiresPermissions("product:brand:save")
    public R save(@Valid @RequestBody BrandEntity brand, BindingResult result){//告诉springMVC这个字段需要校验,后面紧跟一个参数可以获取错误信息
        if(result.hasErrors()){
            Map<String ,String> map=new HashMap<>();
            result.getFieldErrors().forEach((item)->{
                String defaultMessage = item.getDefaultMessage();//获取信息
                String field=item.getField();//获取错误的名字
                map.put(field,defaultMessage);
            });
            return R.error(400,"提交的数据不合法").put("data",map);
        }else{
            brandService.save(brand);
            return R.ok();
        }
    }

用postman发送一个空串,这时候就会报400错误

 

 给出完整的校验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 = "品牌名不能为空")//非空,空串也不行
    private String name;
    /**
     * 品牌logo地址
     */
    @NotEmpty
    @URL(message = "logo必须是url地址")//必须是一个url地址
    private String logo;
    /**
     * 介绍
     */
    private String descript;
    /**
     * 显示状态[0-不显示;1-显示]
     */
    private Integer showStatus;
    /**
     * 检索首字母
     */
    @NotEmpty
    @Pattern(regexp = "/^[a-zA-z]$/",message = "检索首字母必须是一个字母")//自定义的规则
    private String firstLetter;
    /**
     * 排序
     */
    @NotNull//integer不能使用notEmpty
    @Min(value = 0,message = "排序必须大于等于0")
    private Integer sort;

}

9.集中异常处理

 我们之前的方法处理异常非常麻烦,现在来统一处理异常

首先把bindingresult那一段代码删掉,不去感知异常,异常就会抛出去

@Slf4j//记录日志
//restController+ControllerAdvice
@RestControllerAdvice(basePackages = "com.wuyimin.gulimall.product.controller")
public class GulimallExceptionControllerAdvice {
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public R handleValidException(MethodArgumentNotValidException e){
        log.error("数据校验出现问题:{},异常类型:{}",e.getMessage(),e.getClass());
        BindingResult bindingResult = e.getBindingResult();//之前的BindingResult属性
        Map<String,String> map=new HashMap<>();
        bindingResult.getFieldErrors().forEach(item->{
            map.put(item.getField(),item.getDefaultMessage());
        });
        return R.error(400,"数据校验出现问题").put("data",map);
    }
}

 

 为了规范枚举一下各种错误状态码放在common模块里

/**
 * @author wuyimin
 * @create 2021-08-06 16:44
 * @description 错误状态码枚举
 */
    /***
     * 错误码和错误信息定义类
     * 1. 错误码定义规则为5为数字
     * 2. 前两位表示业务场景,最后三位表示错误码。例如:100001。10:通用 001:系统未知异常
     * 3. 维护错误码后需要维护错误描述,将他们定义为枚举形式
     * 错误码列表:
     *  10: 通用
     *      001:参数格式校验
     *  11: 商品
     *  12: 订单
     *  13: 购物车
     *  14: 物流
     * @author ZSY
     */
    public enum BizCodeEnum {
        /**
         * 系统未知异常
         */
        UNKNOWN_EXCEPTION(10000, "系统未知异常"),
        /**
         * 参数校验错误
         */
        VALID_EXCEPTION(10001, "参数格式校验失败");
        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;
        }
    }

更改后的代码

@Slf4j//记录日志
//restController+ControllerAdvice
@RestControllerAdvice(basePackages = "com.wuyimin.gulimall.product.controller")
public class GulimallExceptionControllerAdvice {
    @ExceptionHandler(value = MethodArgumentNotValidException.class)
    public R handleValidException(MethodArgumentNotValidException e){
        log.error("数据校验出现问题:{},异常类型:{}",e.getMessage(),e.getClass());
        BindingResult bindingResult = e.getBindingResult();//之前的BindingResult属性
        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);
    }

    //其他任何异常都默认返回error
    @ExceptionHandler(value=Throwable.class)
    public R handleException(Throwable throwable){
        return R.error(BizCodeEnum.UNKNOWN_EXCEPTION.getCode(),BizCodeEnum.UNKNOWN_EXCEPTION.getMsg());
    }
}

public enum BizCodeEnum {
        /**

UNKNOWN_EXCEPTION(10000, "系统未知异常"),
/**

VALID_EXCEPTION(10001, "参数格式校验失败");
        private final int code;
        private final String msg;

            return code;
}
        public String getMsg() {
            return msg;
}
    }

测试校验

 10.分组校验+自定义校验注解

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 = "修改必须指定品牌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 = "品牌名必须提交", groups = {AddGroup.class, UpdateGroup.class})
    private String name;
    /**
     * 品牌logo地址
     */
    @NotBlank(groups = {AddGroup.class})
    @URL(message = "logo必须是一个合法的url地址", groups = {AddGroup.class, UpdateGroup.class})
    private String logo;
    /**
     * 介绍
     */
    private String descript;
    /**
     * 显示状态[0-不显示;1-显示]
     */
//  @Pattern()
    @NotNull(groups = {AddGroup.class, UpdateStatusGroup.class})
    @ListValue(vals = {0, 1}, groups = {AddGroup.class, UpdateStatusGroup.class})
    private Integer showStatus;
    /**
     * 检索首字母
     */
    @NotEmpty(groups = {AddGroup.class})
    @Pattern(regexp = "^[a-zA-Z]$", message = "检索首字母必须是一个字母", groups = {AddGroup.class, UpdateGroup.class})
    private String firstLetter;
    /**
     * 排序
     */
    @NotNull(groups = {AddGroup.class})
    @Min(value = 0, message = "排序必须大于等于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();
    }

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

自定义校验:

common引入依赖

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

自定义注解

add update updateStatus是三个空接口用于给校验注解分类

 

 ListValue自定义注解

@Documented
@Constraint(validatedBy = {ListValueConstraintValidator.class})//关联自定义的校验器
@Target({METHOD, FIELD, ANNOTATION_TYPE, CONSTRUCTOR, PARAMETER, TYPE_USE})
@Retention(RUNTIME)
public @interface ListValue {
    String message() default "{com.wuyimin.common.valid.ListValue.message}";//提示信息从ValidationMessages.Properties里拿到,也可以直接定义

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

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

    int[] vals() default {};
}

校验器 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);
        }
    }
    //判断是否校验成功
    /**
     *
     * @param integer 需要校验的值
     * @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
    }
}

测试
