JDBC/c3p0 kullanarak MariaDB'ye bağlanma

Question

Sadece MySQL'den MariaDb'ye geçiş sürecindeyiz. JDBC URL'sini ve JDBC Sürücüsünü güncellemek kadar kolay olacağını umuyordum ama maalesef bu yeterli değildi.

mariadb sürümü: 5.5.47-MariaDB

Yapılandırma:

db.driver=org.mariadb.jdbc.Driver 
db.url=jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull&autoReconnect=true 
db.user=user 
db.password=secret 

Sürücü:

<dependency> 
     <groupId>org.mariadb.jdbc</groupId> 
     <artifactId>mariadb-java-client</artifactId> 
     <version>1.4.2</version> 
</dependency> 

c3po tanımı, hiçbir şey MySQL ile aynıdır, burada değişti:

<bean id="c3p0dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close"> 
    <!-- access --> 
    <property name="driverClass" value="${db.driver}" /> 
    <property name="jdbcUrl" value="${db.url}" /> 
    <property name="user" value="${db.user}" /> 
    <property name="password" value="${db.password}" /> 
    .... 

hatası:

Zaten birkaç şey denedim ama şimdiye kadar hiçbir şey yardımcı olur:

Yeni şifre biçimini kullanmayı deneyin db.url=jdbc:mariadb://localhost... çalıştı: update mysql.user set Password = PASSWORD('secret') where user = 'user'; Herhangi bir yardım mutluluk duyacağız

aşağıdaki özel durum alırsınız. Ben yeni şifreye güncelleme işe yaramadı öğrendim bazı ek testlerden sonra

Answer 1

:

MariaDB [test]> SELECT PASSWORD('123456'), OLD_PASSWORD('123456'); 
+--------------------+------------------------+ 
| PASSWORD('123456') | OLD_PASSWORD('123456') | 
+--------------------+------------------------+ 
| 565491d704013245 | 565491d704013245  | 
+--------------------+------------------------+ 

biz /etc/my.cnf belirlenen old_passwords seçeneği varmış. Kapatıp MariaDb'yi yeniden başlattıktan sonra yeni PASSWORD() düzgün çalışmaya başladı ve şimdi bağlanabiliyoruz. Umarım hata ayıklama mücadelelerinde birileri için yararlı olur.

> SHOW VARIABLES LIKE 'old_passwords'; 
+---------------+-------+ 
| Variable_name | Value |

| old_passwords | 0  |

> SELECT PASSWORD('123456'), OLD_PASSWORD('123456'); 
+-------------------------------------------+------------------------+ 
| PASSWORD('123456')      | OLD_PASSWORD('123456') |
