spring 手动添加 bean 到容器,例子 :多数据源配置

package com.thunisoft.spsjsb.config.db.decrypt;

import com.alibaba.druid.pool.DruidDataSource;
import com.thunisoft.spsjsb.config.AppEnv;
import org.springframework.beans.factory.support.BeanDefinitionBuilder;
import org.springframework.beans.factory.support.DefaultListableBeanFactory;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration; import javax.sql.DataSource; @Configuration
public class MultiDsConf { @Bean
public Integer doRun() {
//获取BeanFactory
DefaultListableBeanFactory defaultListableBeanFactory = (DefaultListableBeanFactory) AppEnv.getCtx().getAutowireCapableBeanFactory(); //创建bean信息.
BeanDefinitionBuilder beanDefinitionBuilder = BeanDefinitionBuilder.genericBeanDefinition(DruidDataSource.class);
beanDefinitionBuilder.addPropertyValue("driverClassName","com.mysql.jdbc.Driver");
beanDefinitionBuilder.addPropertyValue("url","jdbc:mysql:///sp_tjpt_dev?useUnicode=true&characterEncoding=utf8&useSSL=false&generateSimpleParameterMetadata=true&useCursorFetch=true&defaultFetchSize=100");
beanDefinitionBuilder.addPropertyValue("username","root");
beanDefinitionBuilder.addPropertyValue("password","123456");
defaultListableBeanFactory.registerBeanDefinition("sjsb", beanDefinitionBuilder.getBeanDefinition()); BeanDefinitionBuilder beanDefinitionBuilder2 = BeanDefinitionBuilder.genericBeanDefinition(DruidDataSource.class);
beanDefinitionBuilder2.addPropertyValue("driverClassName","net.sourceforge.jtds.jdbc.Driver");
beanDefinitionBuilder2.addPropertyValue("url","jdbc:jtds:sybase:///YWST");
beanDefinitionBuilder2.addPropertyValue("username","sa");
beanDefinitionBuilder2.addPropertyValue("password","123456");
defaultListableBeanFactory.registerBeanDefinition("np", beanDefinitionBuilder2.getBeanDefinition()); return 1;
}
}
