SpringBoot数据校验

1. 添加pom依赖

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

2. 编写实体类

   /**
    * @author wsyjlly
    * @create 2019.06.29 - 12:18
    **/
   @AllArgsConstructor
   @NoArgsConstructor
   @Accessors
   @Data
   @TableName(value = "message")
   public class Message implements Serializable {
       private Integer id;
       private Integer mid;
   
       @Size(min = 5,max = 10,message = "{message.content.size}")
       @NotNull(message = "{message.content.notnull}")
       private String content;
   
       @Size(min = 5,max = 10,message = "{message.column1.size}")
       @NotNull(message = "{message.column1.notnull}")
       @TableField(value = "column_200")
       private String column1;
   
       @Size(min = 5,max = 10,message = "{message.column2.size}")
       @NotNull(message = "{message.column2.notnull}")
       @TableField(value = "column_500")
       private String column2;
   
       @Size(min = 5,max = 10,message = "{message.column3.size}")
       @NotNull(message = "{message.column3.notnull}")
       @TableField(value = "column_5000")
       private String column3;
   }

3. ValidationMessages.properties配置

   message.content.notnull=该字段不能为空
   message.column1.notnull=该字段不能为空
   message.column2.notnull=该字段不能为空
   message.column3.notnull=该字段不能为空
   message.content.size=内容长度过短
   message.column1.size=内容长度过短
   message.column2.size=内容长度过短
   message.column3.size=内容长度过短

4. Controller校验

   /**
    * @author wsyjlly
    * @create 2019.07.17 - 17:34
    **/
   @RestController
   @RequestMapping("/message")
   public class MessageController {
       @PostMapping("/validate")
       public List validate(@RequestBody @Validated Message message, BindingResult result){
           System.out.println(message);
           ArrayList<Object> list = new ArrayList<>();
           if (result.hasErrors()) list.addAll(result.getAllErrors());
           for (ObjectError item : result.getAllErrors()){
               System.out.println(item);
           }
           list.add(message);
           return list;
       }
   }

5. 分组校验

   • 创建分组接口

     /**
      * @author wsyjlly
      * @create 2019.07.17 - 18:29
      **/
     @Component
     public interface ValidationGroup1 {}

     /**
      * @author wsyjlly
      * @create 2019.07.17 - 18:29
      **/
     @Component
     public interface ValidationGroup2 {}

   • 实体类添加分组

     /**
      * @author wsyjlly
      * @create 2019.06.29 - 12:18
      **/
     @AllArgsConstructor
     @NoArgsConstructor
     @Accessors
     @Data
     @TableName(value = "message")
     public class Message implements Serializable {
         private Integer id;
         private Integer mid;
     
         @Size(min = 5,max = 10,message = "{message.content.size}")
         @NotNull(message = "{message.content.notnull}")
         private String content;
     
         @Size(min = 5,max = 10,message = "{message.column1.size}")
         @NotNull(message = "{message.column1.notnull}")
         @TableField(value = "column_200")
         private String column1;
     
         @Size(min = 5,max = 10,message = "{message.column2.size}",groups = ValidationGroup1.class)
         @NotNull(message = "{message.column2.notnull}")
         @TableField(value = "column_500")
         private String column2;
     
         @Size(min = 5,max = 10,message = "{message.column3.size}",groups = {ValidationGroup1.class, ValidationGroup2.class})
         @NotNull(message = "{message.column3.notnull}")
         @TableField(value = "column_5000")
         private String column3;
     }

   • Controller校验指定分组

     /**
      * @author wsyjlly
      * @create 2019.07.17 - 17:34
      **/
     @RestController
     public class ValidateController {
     
         @PostMapping("/validate1")
         public List validate(@RequestBody @Validated Message message, BindingResult result){
             System.out.println(message);
             ArrayList<Object> list = getObjects(result);
             list.add(message);
             return list;
         }
         
         @PostMapping("/validate2")
         public List validate2(@RequestBody @Validated(ValidationGroup1.class) Message message, BindingResult result){
             System.out.println(message);
             ArrayList<Object> list = getObjects(result);
     list.add(message);
             return list;
         }
         
         @PostMapping("/validate3")
         public List validate3(@RequestBody @Validated(ValidationGroup2.class) Message message, BindingResult result){
             System.out.println(message);
             ArrayList<Object> list = getObjects(result);
             list.add(message);
             return list;
         }
     
         private ArrayList<Object> getObjects(BindingResult result) {
             ArrayList<Object> list = new ArrayList<>();
             if (result.hasErrors()) {
                 for (ObjectError item : result.getAllErrors()) {
                     list.add(item.getDefaultMessage());
                     System.out.println(item.getDefaultMessage());
                 }
             }
             return list;
         }
     }
