com.mysql.jdbc.MysqlDataTruncation：数据截断：第1行的'aboutMeText'列数据太长

Question

我正在尝试使用Spring-JPA更新列的值，值是emoji / smilies。但是收到错误消息说java.sql.BatchUpdateException：不正确的字符串值：'\ xF0 \ x9F \ x98 \ x84 \ xF0 \ x9F ...'

这是连接网址-

jdbc.url=jdbc:mysql:localhost:3306/woo?autoReconnect=true&useUnicode=true&characterEncoding=UTF-8&connectionCollation=utf8mb4_unicode_ci&characterSetResults=UTF-8

这是调用代码

userProfile.setAboutMeText("\uD83D\uDE04\uD83D\uDC68\u200D\u2764\uFE0F\u200D\uD83D\uDC8B\u200D\uD83D\uDC68\uD83D\uDE02\uD83D\uDE20");

这是实体

 @Entity
public class UserProfile implements Serializable {

    @Column(length = 1000)
private String aboutMeText;
@Id
private Long id;
public Long getId() {
    return id;
}

public void seId(Long id) {
    this.id = id;
}


public String getAboutMeText() {
   return JsonEscape.unescapeJson(aboutMeText);


}
 public void setAboutMeText(String aboutMeText) {
   this.aboutMeText = JsonEscape.escapeJson(aboutMeText);


}

和

这是完整的错误：

我尝试并检查了关于stackoverflow，stackexchange等的各种帖子，并进行了一些更改，但仍然无法解决问题。

Answer 1

通过alter和code和db将aboutMeText的大小从1000增加到3000。

@Column(length = 3000) 
private String aboutMeText;

这样做com.mysql.jdbc.MysqlDataTruncation：数据截断：数据太长异常已消失，我得到了所需的输出。
