一、使用jdbc 配置多数据源
1.yml数据源配置
2.配置类
package com.v246.common.config.datasource;
import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.core.JdbcOperations;
import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import javax.sql.DataSource;
//表示这个类为一个配置类
@Configuration
public class DatasourceConfig {
// 将这个对象放入Spring容器中
@Bean("datavisualDataSource")
// 表示这个数据源是默认数据源
@Primary
@Qualifier("datavisualDataSource")
// 读取application.properties中的配置参数映射成为一个对象
// prefix表示参数的前缀
@ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.datavisual")
public DataSource datavisualDataSource(){
return DruidDataSourceBuilder.create().build();
}
@Bean("vlmsDataSource")
@Qualifier("vlmsDataSource")
@ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.vlms")
public DataSource vlmsDataSource(){
return DruidDataSourceBuilder.create().build();
}
@Bean("jdbcTemplate")
public JdbcTemplate datavisualJdbcOperations(@Qualifier("datavisualDataSource") DataSource datavisualDataSource) {
return new JdbcTemplate(datavisualDataSource);
}
@Bean("vlmsJdbcTemplate")
public JdbcOperations vlmsJdbcOperations(@Qualifier("vlmsDataSource") DataSource vlmsDataSource) {
return new JdbcTemplate(vlmsDataSource);
}
@Bean
@Primary
public PlatformTransactionManager datavisualTransactionManager(@Qualifier("datavisualDataSource") DataSource datavisualDataSource) {
return new DataSourceTransactionManager(datavisualDataSource);
}
@Bean
public PlatformTransactionManager vlmsTransactionManager(@Qualifier("vlmsDataSource") DataSource vlmsDataSource) {
return new DataSourceTransactionManager(vlmsDataSource);
}
@Bean(name = "sqlSessionFactory")
// 表示这个数据源是默认数据源
@Primary
// @Qualifier表示查找Spring容器中名字为DataSource的对象
public SqlSessionFactory test1SqlSessionFactory(@Qualifier("datavisualDataSource") DataSource datasource)
throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(datasource);
bean.setMapperLocations(
// 设置mybatis的xml所在位置
new PathMatchingResourcePatternResolver().getResources("classpath*:mapping/mapper/*.xml"));
return bean.getObject();
}
@Bean(name = "vlmsSqlSessionFactory")
// @Qualifier表示查找Spring容器中名字为DataSource的对象
public SqlSessionFactory vlmsSqlSessionFactory(@Qualifier("vlmsDataSource") DataSource datasource)
throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(datasource);
bean.setMapperLocations(
// 设置mybatis的xml所在位置
new PathMatchingResourcePatternResolver().getResources("classpath*:mapping/test01/*.xml"));
return bean.getObject();
}
}
3.测试类
public class SqlserverServiceTest {
@Resource
JdbcTemplate vlmsJdbcTemplate;
@Autowired
NamedDb db;
@Test
public void testTime() {
Map<String,Object> map = vlmsJdbcTemplate.queryForMap("SELECT * FROM wx_user WHERE user_id='***'");
System.out.println(map);
Record rc = db.findFirst("SELECT * FROM SYSC03 WHERE CGRDM='***'");
System.out.println(rc);
}
}
二、使用mybatis 配置多数据源
1.yml数据源配置
2.prom.xml配置
<!--引入dynamic-datasource-spring-boot-starter。-->
<dependency>
<groupId>com.baomidou</groupId>
<artifactId>dynamic-datasource-spring-boot-starter</artifactId>
<version>2.5.6</version>
</dependency>
3.测试类
// 默认为主数据源 使用@DS（"数据源名称"）则使用新其他数据源@DS("vlms")
public interface BiZcPlanShipmentMapper extends IBaseMapper<BiZcPlanShipment> {
Page<Record> getDataList(@Param("filterPage")Page<Record> page);
}
第二种mybatis 配置方法可参考 https://mp.baomidou.com/guide/dynamic-datasource.html
package com.v246.common.config.datasource;import com.alibaba.druid.spring.boot.autoconfigure.DruidDataSourceBuilder;import org.apache.ibatis.session.SqlSessionFactory;import org.mybatis.spring.SqlSessionFactoryBean;import org.springframework.beans.factory.annotation.Qualifier;import org.springframework.boot.context.properties.ConfigurationProperties;import org.springframework.context.annotation.Bean;import org.springframework.context.annotation.Configuration;import org.springframework.context.annotation.Primary;import org.springframework.core.io.support.PathMatchingResourcePatternResolver;import org.springframework.jdbc.core.JdbcOperations;import org.springframework.jdbc.core.JdbcTemplate;import org.springframework.jdbc.datasource.DataSourceTransactionManager;import org.springframework.transaction.PlatformTransactionManager;import javax.sql.DataSource;//表示这个类为一个配置类@Configurationpublic class DatasourceConfig { // 将这个对象放入Spring容器中@Bean("datavisualDataSource") // 表示这个数据源是默认数据源@Primary @Qualifier("datavisualDataSource") // 读取application.properties中的配置参数映射成为一个对象 // prefix表示参数的前缀@ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.datavisual") public DataSource datavisualDataSource(){ return DruidDataSourceBuilder.create().build();} @Bean("vlmsDataSource") @Qualifier("vlmsDataSource") @ConfigurationProperties(prefix = "spring.datasource.dynamic.datasource.vlms") public DataSource vlmsDataSource(){ return DruidDataSourceBuilder.create().build();} @Bean("jdbcTemplate") public JdbcTemplate datavisualJdbcOperations(@Qualifier("datavisualDataSource") DataSource datavisualDataSource) { return new JdbcTemplate(datavisualDataSource);} @Bean("vlmsJdbcTemplate") public JdbcOperations vlmsJdbcOperations(@Qualifier("vlmsDataSource") DataSource vlmsDataSource) { return new JdbcTemplate(vlmsDataSource);} @Bean @Primarypublic PlatformTransactionManager datavisualTransactionManager(@Qualifier("datavisualDataSource") DataSource datavisualDataSource) { return new DataSourceTransactionManager(datavisualDataSource);} @Beanpublic PlatformTransactionManager vlmsTransactionManager(@Qualifier("vlmsDataSource") DataSource vlmsDataSource) { return new DataSourceTransactionManager(vlmsDataSource);} @Bean(name = "sqlSessionFactory") // 表示这个数据源是默认数据源@Primary// @Qualifier表示查找Spring容器中名字为DataSource的对象public SqlSessionFactory test1SqlSessionFactory(@Qualifier("datavisualDataSource") DataSource datasource) throws Exception { SqlSessionFactoryBean bean = new SqlSessionFactoryBean();bean.setDataSource(datasource);bean.setMapperLocations( // 设置mybatis的xml所在位置new PathMatchingResourcePatternResolver().getResources("classpath*:mapping/mapper/*.xml")); return bean.getObject();} @Bean(name = "vlmsSqlSessionFactory") // @Qualifier表示查找Spring容器中名字为DataSource的对象public SqlSessionFactory vlmsSqlSessionFactory(@Qualifier("vlmsDataSource") DataSource datasource) throws Exception { SqlSessionFactoryBean bean = new SqlSessionFactoryBean();bean.setDataSource(datasource);bean.setMapperLocations( // 设置mybatis的xml所在位置new PathMatchingResourcePatternResolver().getResources("classpath*:mapping/test01/*.xml")); return bean.getObject();}}
