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
<template> <el-dialog :title="!dataForm.id ? '新增' : '修改'" :close-on-click-modal="false" :visible.sync="visible" > <el-form :model="dataForm" :rules="dataRule" ref="dataForm" @keyup.enter.native="dataFormSubmit()" label-width="140px" > <el-form-item label="品牌名" prop="name"> <el-input v-model="dataForm.name" placeholder="品牌名"></el-input> </el-form-item> <el-form-item label="品牌logo地址" prop="logo"> <!-- <el-input v-model="dataForm.logo" placeholder="品牌logo地址"></el-input> --> <single-upload v-model="dataForm.logo"></single-upload> </el-form-item> <el-form-item label="介绍" prop="descript"> <el-input v-model="dataForm.descript" placeholder="介绍"></el-input> </el-form-item> <el-form-item label="显示状态" prop="showStatus"> <el-switch v-model="dataForm.showStatus" active-color="#13ce66" inactive-color="#ff4949" :active-value="1" :inactive-value="0" ></el-switch> </el-form-item> <el-form-item label="检索首字母" prop="firstLetter"> <el-input v-model="dataForm.firstLetter" placeholder="检索首字母"></el-input> </el-form-item> <el-form-item label="排序" prop="sort"> <el-input v-model.number="dataForm.sort" placeholder="排序"></el-input> </el-form-item> </el-form> <span slot="footer" class="dialog-footer"> <el-button @click="visible = false">取消</el-button> <el-button type="primary" @click="dataFormSubmit()">确定</el-button> </span> </el-dialog> </template> <script> import SingleUpload from '@/components/upload/singleUpload'; export default { components: {SingleUpload}, data() { return { visible: false, dataForm: { brandId: 0, name: "", logo: "", descript: "", showStatus: 1, firstLetter: "", sort: 0 }, dataRule: { name: [{required: true, message: "品牌名不能为空", trigger: "blur"}], logo: [ {required: true, message: "品牌logo地址不能为空", trigger: "blur"} ], descript: [ {required: true, message: "介绍不能为空", trigger: "blur"} ], showStatus: [ { required: true, message: "显示状态[0-不显示；1-显示]不能为空", trigger: "blur" } ], firstLetter: [ { validator: (rule, value, callback) => { if (value == "") { callback(new Error("首字母必须填写")); } else if (!/^[a-zA-Z]$/.test(value)) { callback(new Error("首字母必须a-z或者A-Z之间")); } else { callback(); } }, trigger: "blur" } ], sort: [ { validator: (rule, value, callback) => { if (value == "") { callback(new Error("排序字段必须填写")); } else if (!Number.isInteger(value) || value < 0) { callback(new Error("排序必须是一个大于等于0的整数")); } else { callback(); } }, trigger: "blur" } ] } }; }, methods: { init(id) { this.dataForm.brandId = id || 0; this.visible = true; this.$nextTick(() => { this.$refs["dataForm"].resetFields(); if (this.dataForm.brandId) { this.$http({ url: this.$http.adornUrl( `/product/brand/info/${this.dataForm.brandId}` ), method: "get", params: this.$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; this.dataForm.showStatus = data.brand.showStatus; this.dataForm.firstLetter = data.brand.firstLetter; this.dataForm.sort = data.brand.sort; } }); } }); }, // 表单提交 dataFormSubmit() { this.$refs["dataForm"].validate(valid => { if (valid) { this.$http({ url: this.$http.adornUrl( `/product/brand/${!this.dataForm.brandId ? "save" : "update"}` ), method: "post", data: this.$http.adornData({ brandId: this.dataForm.brandId || undefined, name: this.dataForm.name, logo: this.dataForm.logo, descript: this.dataForm.descript, showStatus: this.dataForm.showStatus, firstLetter: this.dataForm.firstLetter, sort: this.dataForm.sort }) }).then(({data}) => { if (data && data.code === 0) { this.$message({ message: "操作成功", type: "success", duration: 1500, onClose: () => { this.visible = false; this.$emit("refreshDataList"); } }); } else { this.$message.error(data.msg); } }); } }); } } }; </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()); } }
/** * @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; } }
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 } }
