问答 多数据源执行报错的问题-求解
发布于 2903天前 作者 lampardlee 2766 次浏览 复制 上一个帖子 下一个帖子
标签: 多数据源 dao

我配了两个数据源
db.properties配置如下：

mysql

db.url=jdbc:mysql://XX.XX.XX.XX:XXXX/nutzwk?useUnicode=true&characterEncoding=utf8
db.username=root
db.password=XXXXXXXX
db.validationQuery=select 1
db.maxActive=100
db.testWhileIdle=true
db.filters=mergeStat
db.connectionProperties=druid.stat.slowSqlMillis=2000
db.defaultAutoCommit=true
db2.url=jdbc:mysql://XX.XX.XX.XX:XXXX/ca?useUnicode=true&characterEncoding=utf8
db2.username=root
db2.password=XXXXXXXX
db2.validationQuery=select 1
db2.maxActive=100
db2.testWhileIdle=true
db2.filters=mergeStat
db2.connectionProperties=druid.stat.slowSqlMillis=2000
db2.defaultAutoCommit=true
dao.js配置如下：
var ioc = {
conf : {
type : "org.nutz.ioc.impl.PropertiesProxy",
fields : {
paths : ["config/custom/"]
}
},
dataSource2 : {
factory : "$conf#make",
args : ["com.alibaba.druid.pool.DruidDataSource", "db2."],
type : "com.alibaba.druid.pool.DruidDataSource",
events : {
create : "init",
depose : 'close'
}
},
dao2 : {
type : "org.nutz.dao.impl.NutDao",
args : [{refer:"dataSource2"}]
/*
fields : {
executor : {refer:"cacheExecutor"}
}
/
},
dataSource : {
factory : "$conf#make",
args : ["com.alibaba.druid.pool.DruidDataSource", "db."],
type : "com.alibaba.druid.pool.DruidDataSource",
events : {
create : "init",
depose : 'close'
}
},
dao : {
type : "org.nutz.dao.impl.NutDao",
args : [{refer:"dataSource"}],
fields : {
executor : {refer:"cacheExecutor"}
}
},
cacheExecutor : {
type : "org.nutz.plugins.cache.dao.CachedNutDaoExecutor",
fields : {
cacheProvider : {refer:"cacheProvider"},
cachedTableNames : ["sys_user", "sys_role", "sys_menu"]
}
},
/
// 基于内存的简单LRU实现
cacheProvider : {
type : "org.nutz.plugins.cache.dao.impl.provider.MemoryDaoCacheProvider",
fields : {
cacheSize : 10000 // 缓存的对象数
},
events : {
create : "init"
}
}
/
// 基于Ehcache的DaoCacheProvider
cacheProvider : {
type : "org.nutz.plugins.cache.dao.impl.provider.EhcacheDaoCacheProvider",
fields : {
cacheManager : {refer:"cacheManager"} // 引用ehcache.json中定义的CacheManager
},
events : {
create : "init"
}
}
};
Service类代码如下：
package com.alphacos.ca.services.ib;
import cn.wizzer.common.base.Service;
import com.alphacos.ca.models.ib.Ib_trade;
import org.nutz.dao.Dao;
import org.nutz.ioc.loader.annotation.IocBean;
/*

@IocBean(args={"dao:refer:dao2"})
public class IbTradeService extends Service {
public IbTradeService(Dao dao) {
super(dao);
}
}
Control类代码如下：
package com.alphacos.ca.controllers.platform.ib;

import cn.wizzer.common.annotation.SLog;

}
编译加载没有报错，第一个数据源所有表能够正常使用，第二个数据源报错：

按一下 插入代码或日志 这个按钮有多难？

@IocBean(args={"refer:dao2"})

多谢耐心解答，果然可以了。
发帖方法不规范给您带来的麻烦，下次一定注意。
再次感谢！
