2.2.2 JDBC數(shù)據源

如果你(nǐ)希望将URule Pro的規則存儲在指定的數(shù)據源中,你(nǐ)可(kě)以使用JDBC數(shù)據源:

Jdbc

JDBC數(shù)據源利用DBCP配置數(shù)據源,配置界面如下:

Jdbc

支持多(duō)種類型的數(shù)據源,例如:

  • DB2
  • 達夢數(shù)據庫
  • HSQL
  • MYSQL
  • ORACLE
  • PostgreSQL
  • SqlServer

根據不通(tōng)的數(shù)據源類型設置不通(tōng)的驅動類,連接URL以及用戶名密碼。

如果使用JDBC數(shù)據源,需要确保當前項目下有(yǒu)對應的JDBC驅動包存在

相關POM的配置參考:

<!-- MYSQL數(shù)據庫 -->
<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>5.1.38</version>
</dependency>
<!-- SQLServer數(shù)據庫 -->
<dependency>

關于驗證鏈接SQL

image-20210922102803507

驗證鏈接SQL對于不通(tōng)的數(shù)據庫是有(yǒu)差别的,如果配錯數(shù)據鏈接驗證就無法通(tōng)過,這兒列出一些(xiē)常用數(shù)據庫的驗證SQL:

數(shù)據庫 驗證SQL
HSQL select 1 from INFORMATION_SCHEMA.SYSTEM_USERS
Oracle select 1 from dual
IBM DB2 select 1 from sysibm.sysdummy1
MySQL select 1
Microsoft SQLServer select 1
SQLite select 1
DM SELECT 1;
PostgreSQL select version();
Informix select 1

Spring定義數(shù)據源

如果采用Spring配置文件定義數(shù)據源,參考配置:

urule.store.database.driver=com.mysql.jdbc.Driver
urule.store.database.password=password
urule.config.type=jdbc
urule.store.database.validationQuery=select 1
urule.store.database.maxIdle=10
urule.store.database.initialsize=0
urule.store.database.platform=mysql
urule.store.database.maxTotal=10
urule.store.database.username=root
urule.store.database.url=jdbc:mysql://localhost:3306/urule?useUnicode=true&characterEncoding=UTF-8
urule.store.database.minIdle=0
