列“ IMAGE BINARY（255）”的值太长

时间：2018-11-26 21:57:09

标签： json spring rest jpa

我正在将JSON帖子发送到spring rest终结点。属性之一是字节数组。但是，当我尝试发送图像文件时，出现此列太长的错误。当我用任意字节替换CURL帖子中的字节数组时，它会起作用。

    package coffee;

import javax.persistence.*;
import lombok.*;
import javax.validation.constraints.*;

@Data
@NoArgsConstructor(access=AccessLevel.PUBLIC, force=true)
@RequiredArgsConstructor
@Entity
public class About {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private final Long id;
    @NotEmpty
    private final String name;
    @NotEmpty
    private final String description;
    private final byte[] image;

}

将post方法发送到Spring Tools Suite时的源代码

答案 0 :(得分：1)

@LOB在字节数组属性上的注释... 

@Data
@NoArgsConstructor(access=AccessLevel.PUBLIC, force=true)
@RequiredArgsConstructor
@Entity
public class About {

    @Id
    @GeneratedValue(strategy=GenerationType.AUTO)
    private final Long id;
    @NotEmpty
    private final String name;
    @NotEmpty
    private final String description;
    @LOB
    private final byte[] image;

答案 1 :(得分：1)

由于您选择的文件太大，请尝试添加

@Lob

来自

@javax.persistence.Lob

Lob表示在以下数据库示例中，带注释的字段应表示为BLOB（二进制数据）：

    @Lob
    @Column(name = "picByte", length = 1000)
    private byte[] picByte;

谢谢✌
