我想使用Spring-JPA更新列的值,值是表情符號/表情符號。 但得到錯誤說java.sql.BatchUpdateException:不正確的字符串值: '\ XF0 \ x9F \ X98 \ X84 \ XF0 \ x9F ......' 對於com.mysql.jdbc.MysqlDataTruncation:數據截斷:數據太長的列'aboutMeText'在第1行

這裏是連接URL-

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

下面是調用代碼

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

這裏是實體

@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); 


} 

這裏是完整的錯誤:

我嘗試和檢查了計算器,stackexchange等各個崗位..和執行了一些變化,但仍無法解決問題。

將排序規則更改爲utf8_unicode_ci ... [檢查此](http://stackoverflow.com/a/20431999/4117061)和[this](http://stackoverflow.com/a/10959780/4117061) –

previous它是utf8_unicode_ci,但我得到相同的錯誤,所以將其改爲utf8mb4_unicode_ci –

它是一個二進制數據,你正在存儲在該列?那麼它不應該是字節[]而不是字符串blob類型? –

將aboutMeText的大小從1000增加到3000,在代碼中和db通過改變。

@Column(length = 3000) 
private String aboutMeText; 

這樣com.mysql.jdbc.MysqlDataTruncation:數據截斷:數據太長例外過去了,我得到了所需的輸出。

你的數據庫的列定義呢? –

在db中增加太多了......'alter table UserProfile modify aboutMeText varchar(3000);'現在這樣做我現在可以發送至少250個emojis,我只能發送85個emojies,如果我輸入了超過85個emojies,數據太長例外。這意味着每個表情符號都被編碼並因此增加了尺寸。 –
