grails连接各个数据库

来源：互联网发布：golang http handler 编辑：程序博客网时间：2024/06/05 11:14

net.sourceforge.jtds.jdbc.Driver 通用

PostgreSQL:（2.5.1格式）
第一步,dataSource中配置：

driverClassName = "org.postgresql.Driver"username = "postgres"  //当前的登录角色password = "111111"

url = "jdbc:postgresql://127.0.0.1:5432/数据库名"

第二步,buildConfig文件中的
grails.project.dependency.resolution的dependencies 改为

dependencies {    // specify dependencies here under either 'build', 'compile', 'runtime', 'test' or 'provided' scopes e.g.    // runtime 'mysql:mysql-connector-java:5.1.29'     runtime 'org.postgresql:postgresql:9.3-1101-jdbc41'   //此句的注释去掉    test "org.grails:grails-datastore-test-support:1.0.2-grails-2.4"}

Mysql：
同pg数据库连接一样，需要改动的地方：

runtime 'mysql:mysql-connector-java:5.1.29'

dialect: org.hibernate.dialect.MySQLInnoDBDialectdriverClassName = "com.mysql.jdbc.Driver"url = "jdbc:mysql://10.20.24.216:3306/crm"

sqlServer:

runtime "net.sourceforge.jtds:jtds:1.3.0"

dialect: org.hibernate.dialect.SQLServerDialectdriverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriverurl: jdbc:jtds : sqlserver://10.20.33.15:1433/FinChinaData_Test

oracle：(3.0.9 格式)
grails-app\conf\application.yml:

driverClassName: oracle.jdbc.driver.OracleDriver         url: jdbc:oracle:thin:@10.20.24.6:1521:orcl

build.gradle:

runtime "com.oracle:ojdbc6:11.2.0.3"
