SpringBoot数据校验

添加pom依赖

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

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;
}

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

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;
    }
}

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;
    }
}
