</beans>增加MultipleDataSource类(保证spring能扫描到)
package com.service.manager.util;
import org.springframework.jdbc.datasource.lookup.AbstractRoutingDataSource;

public static final String datasource = "datasource";
public static final String datasource1 = "datasource1";
private static final ThreadLocal<String> dataSourceKey = new InheritableThreadLocal<String>();
public static void setDataSourceKey(String dataSource) {
dataSourceKey.set(dataSource);
}
@Override
protected Object determineCurrentLookupKey() {
// TODO Auto-generated method stub
return dataSourceKey.get();
}
}增加配置文件:
[html] view plain copy jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&autoreconnect=true&zeroDateTimeBehavior=convertToNull jdbc.username=root jdbc.password= jdbc.driver1=com.mysql.jdbc.Driver jdbc.url1=jdbc:mysql://localhost:3306/test1?useUnicode=true&characterEncoding=utf-8&autoreconnect=true&zeroDateTimeBehavior=convertToNull jdbc.username1=root jdbc.password1=
Controller切换数据源:
MultipleDataSource.setDataSourceKey(MultipleDataSource.datasource);
