Post请求body为list，校验里面的对象

一时失言乱红尘 2022-10-19 01:39 72阅读 0赞

@RequestMapping(value = "/save", method = RequestMethod.POST)
    @ResponseBody
    public List<SaveVideo> saveVideo(@Validated @RequestBody List<SaveVideo> video, BindingResult bindingResult) {
            // 省略业务代码
    }

body的参数：

> \[\{“sysNo”：“HIKID098”，“videoType”：“01”，“videoName"："高清小视频"\}，\{...\}\]

public class SaveVideo{
     
        private static final long serialVersionUID = 1L;
     
        @NotBlank(message = "系统编号不能为空")
        private String sysNo;
     
        @NotBlank(message = "影像类型不能为空")
        private String videoType;
     
        @NotBlank(message = "影像名称不能为空")
        private String videoName;
    
    }

**自定义一个ValidList<E>实现List<E>，并在成员属性上添加@Valid注解，这样就可以校验list里得对象的属性**

/**
     * FileName: ValidList
     * DESCRIPTION: 参数校验工具类, 用于校验List<E> 类型的请求参数
     */
    public class ValidList<E> implements List<E> {
     
        @Valid
        private List<E> list = new ArrayList<>();
     
        @Override
        public int size() {
            return list.size();
        }
     
        @Override
        public boolean isEmpty() {
            return list.isEmpty();
        }
     
        @Override
        public boolean contains(Object o) {
            return list.contains(o);
        }
     
        @Override
        public Iterator<E> iterator() {
            return list.iterator();
        }
     
        @Override
        public Object[] toArray() {
            return list.toArray();
        }
     
        @Override
        public <T> T[] toArray(T[] a) {
            return list.toArray(a);
        }
     
        @Override
        public boolean add(E e) {
            return list.add(e);
        }
     
        @Override
        public boolean remove(Object o) {
            return list.remove(o);
        }
     
        @Override
        public boolean containsAll(Collection<?> c) {
            return list.containsAll(c);
        }
     
        @Override
        public boolean addAll(Collection<? extends E> c) {
            return list.addAll(c);
        }
     
        @Override
        public boolean addAll(int index, Collection<? extends E> c) {
            return list.addAll(index, c);
        }
     
        @Override
        public boolean removeAll(Collection<?> c) {
            return list.removeAll(c);
        }
     
        @Override
        public boolean retainAll(Collection<?> c) {
            return list.retainAll(c);
        }
     
        @Override
        public void clear() {
            list.clear();
        }
     
        @Override
        public E get(int index) {
            return list.get(index);
        }
     
        @Override
        public E set(int index, E element) {
            return list.set(index, element);
        }
     
        @Override
        public void add(int index, E element) {
            list.add(index, element);
        }
     
        @Override
        public E remove(int index) {
            return list.remove(index);
        }
     
        @Override
        public int indexOf(Object o) {
            return list.indexOf(o);
        }
     
        @Override
        public int lastIndexOf(Object o) {
            return list.lastIndexOf(o);
        }
     
        @Override
        public ListIterator<E> listIterator() {
            return list.listIterator();
        }
     
        @Override
        public ListIterator<E> listIterator(int index) {
            return list.listIterator(index);
        }
     
        @Override
        public List<E> subList(int fromIndex, int toIndex) {
            return list.subList(fromIndex, toIndex);
        }
     
        public List<E> getList() {
            return list;
        }
     
        public void setList(List<E> list) {
            this.list = list;
        }
    }

最后修改控制器：使用自定义的validList去接收参数即可。

@RequestMapping(value = "/save", method = RequestMethod.POST)
    @ResponseBody
    public List<SaveVideo> saveVideo(@Validated @RequestBody ValidList<SaveVideo> video, BindingResult bindingResult) {
      // 省略业务代码
    }

# 方法二：使用@validated注解即可 #

@Validated
    @ApplySecurity
    @RequestMapping("/swindle")
    public class SwindleInfoController {
    
        
        @PostMapping("/persons")
        @AuthorityCode(values = AuthorityCodeConstants.GET_RISK_PERSON)
        @ApiResponses({
                @ApiResponse(code = 200, message = "获取成功"),
                @ApiResponse(code = 400, message = "请求参数不合法", response = ErrorResponse.class),
                @ApiResponse(code = 500, message = "系统异常", response = ErrorResponse.class)
        })
        @RequestLog(transCode = RISK_PERSON, procInfo = "'swindlePersonRequests=' + #swindlePersonRequests")
    
        @ApiOperation(value = "申请涉案人员核查", httpMethod = "POST")
        public SwindlePersonResponse getSwindlePersons(@Valid @RequestBody List<SwindlePersonRequest> swindlePersonRequests) {
            return swindleInfoService.getSwindlePerson(swindlePersonRequests);
        }
    
    }
    
    @Getter
    @Setter
    @Validated
    @ToString
    @ApiModel(value = "SwindlePersonRequest", description = "涉案人员查询体(集合最长长度支持10)")
    public class SwindlePersonRequest {
    
            @ApiModelProperty(
                    value = "自然人名称",
                    name = "name",
                    example = "武夷三")
            @Length(max = 200, message = "自然人名称长度不能超过200")
            @NotBlank(message = "自然人名称不能为空")
            private String name;
    
            @ApiModelProperty(
                    value = "证件号码",
                    name = "certificateNo",
                    example = "91440300100016860X")
            @NotBlank(message = "证件号码不能为空")
            private String certificateNo;
    
            @ApiModelProperty(
                    value = "证件类型不能为空",
                    name = "certificateType",
                    example = "P01")
            @NotBlank(message = "证件类型不能为空")
            private String certificateType;
    
    
    }
