感觉通过new AutoTableBindPlugin应该是支持多数据源的吧？如何在继承Model后通过注释方式指定数据源？

Question

@绝望的八皮 你好，想跟你请教个问题：

就是懒得在config类中写代码

//配置druid连接池
        DruidPlugin druidDefault = new DruidPlugin(getProperty("db.default.url"), getProperty("db.default.user"), getProperty("db.default.password"), getProperty("db.default.driver"));
        // StatFilter提供JDBC层的统计信息
        druidDefault.addFilter(new StatFilter());
        // WallFilter的功能是防御SQL注入攻击
        WallFilter wallDefault = new WallFilter();
        wallDefault.setDbType("h2");
        druidDefault.addFilter(wallDefault);

        druidDefault.setInitialSize(getPropertyToInt("db.default.poolInitialSize"));
        druidDefault.setMaxPoolPreparedStatementPerConnectionSize(getPropertyToInt("db.default.poolMaxSize"));
        druidDefault.setTimeBetweenConnectErrorMillis(getPropertyToInt("db.default.connectionTimeoutMillis"));

      DruidPlugin druidCustom = new DruidPlugin(getProperty("db.custom.url"), getProperty("db.custom.user"), getProperty("db.custom.password"), getProperty("db.custom.driver"));
      // StatFilter提供JDBC层的统计信息

db.default.driver=org.h2.Driver
db.default.url=jdbc:h2:file:./db/dreampie
db.default.user=sa
db.default.password=file password dreampie
# Connection Pool settings
db.default.poolInitialSize=10
db.default.poolMaxSize=20
db.default.connectionTimeoutMillis=1000
#In production mode, migration is done automatically if db.${dbName}.migration.auto
#is set to be true in application.conf. Otherwise it failed to start when migration is needed.
db.default.valid.clean=true
db.default.migration.auto=true
db.default.migration.initOnMigrate=true

配置两份数据库  properties就行了

Answer 2

JFinal 提供的 Db + Record 模式支持多数据源，以后考虑让 Model 也支持多数据源

Answer 3

数据源就是一个datesource.一个arp 绑定一个ds.那么建立多个arp 不就是多数据源了

Answer 4

AutoTableBindPlugin只是简单的转调activiRecordPlugin的方法,ar中能支持的就能支持不能支持的也不能.arp.addMapping貌似是不能支持多数据源的吧
