1.配置多数据源
spring:
# mybatis 连接多数据源配置
db1-mybatis:
datasource:
jdbcurl: jdbc:mysql://127.0.0.1:3306/cloud-main1?useUnicode=true&characterEncoding=utf8&useSSL=false&allowMultiQueries=true
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
db2-mybatis:
datasource:
jdbcurl: jdbc:mysql://127.0.0.1:3306/cloud-main2?useUnicode=true&characterEncoding=utf8&useSSL=false&allowMultiQueries=true
username: root
password: 123456
driver-class-name: com.mysql.jdbc.Driver
type: com.alibaba.druid.pool.DruidDataSource
2.db1 配置
package com.example.demo.mybatis.config; import org.apache.ibatis.session.SqlSessionFactory; import org.mybatis.spring.SqlSessionFactoryBean; import org.mybatis.spring.SqlSessionTemplate; import org.mybatis.spring.annotation.MapperScan; import org.springframework.beans.factory.annotation.Qualifier; import org.springframework.boot.context.properties.ConfigurationProperties; import org.springframework.boot.jdbc.DataSourceBuilder; 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.core.io.support.ResourcePatternResolver; import org.springframework.jdbc.datasource.DataSourceTransactionManager; import javax.sql.DataSource; @Configuration @MapperScan(basePackages = "com.example.demo.mybatis.dbs.db1.dao", sqlSessionFactoryRef = "db1SessionFactory") public class DB1Config { @Primary @Bean(name = "db1Mybatis") @ConfigurationProperties(prefix = "spring.db1-mybatis.datasource") public DataSource db1DataSource() { return DataSourceBuilder.create().build(); } @Primary @Bean(name = "db1TransactionManager") public DataSourceTransactionManager transactionManager(@Qualifier("db1Mybatis") DataSource dataSource) { return new DataSourceTransactionManager(dataSource); } @Primary @Bean(name = "db1SessionFactory") public SqlSessionFactory sqlSessionFactory(@Qualifier("db1Mybatis") DataSource dataSource) throws Exception { SqlSessionFactoryBean bean = new SqlSessionFactoryBean(); org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration(); configuration.setMapUnderscoreToCamelCase(true); bean.setConfiguration(configuration); bean.setDataSource(dataSource); ResourcePatternResolver rsourcePatternResolver = new PathMatchingResourcePatternResolver(); bean.setMapperLocations(rsourcePatternResolver.getResources("com/example/demo/mybatis/dbs/db1/mapper/*.xml")); return bean.getObject(); } @Primary @Bean(name = "db1Template") public SqlSessionTemplate sqlSessionTemplate(@Qualifier("db1SessionFactory") SqlSessionFactory sqlSessionFactory) { SqlSessionTemplate sqlSessionTemplate = new SqlSessionTemplate(sqlSessionFactory); return sqlSessionTemplate; } }
3.db2配置
package com.example.demo.mybatis.config;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.core.io.support.ResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import javax.sql.DataSource;
@Configuration
@MapperScan(basePackages = "com.example.demo.mybatis.dbs.db2.mapper", sqlSessionFactoryRef = "db2SessionFactory")
public class DB2Config {
@Bean(name = "db2Mybatis")
@ConfigurationProperties(prefix = "spring.db2-mybatis.datasource")
public DataSource mysqlDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "db2TransactionManager")
public DataSourceTransactionManager transactionManager(@Qualifier("db1Mybatis") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "db2SessionFactory")
public SqlSessionFactory sqlSessionFactory(@Qualifier("db1Mybatis") DataSource dataSource) throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
org.apache.ibatis.session.Configuration configuration = new org.apache.ibatis.session.Configuration();
configuration.setMapUnderscoreToCamelCase(true);
bean.setConfiguration(configuration);
bean.setDataSource(dataSource);
ResourcePatternResolver rsourcePatternResolver = new PathMatchingResourcePatternResolver();
bean.setMapperLocations(rsourcePatternResolver.getResources("classpath*:com/example/demo/mybatis/dbs/db2/*.xml"));
return bean.getObject();
}
@Bean(name = "db2Template")
public SqlSessionTemplate sqlSessionTemplate(@Qualifier("db2SessionFactory") SqlSessionFactory sqlSessionFactory) {
SqlSessionTemplate sqlSessionTemplate = new SqlSessionTemplate(sqlSessionFactory);
return sqlSessionTemplate;
}
}
3.实体Modle
public class User {
………………
}
4.*Mapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.example.demo.mybatis.dbs.db1.dao.UserMapper" >
<resultMap id="BaseResultMap" type="com.example.demo.mybatis.dbs.db1.model.User" >
<constructor >
<idArg column="USER_ID" jdbcType="CHAR" javaType="java.lang.String" />
<arg column="LOGIN_NAME" jdbcType="VARCHAR" javaType="java.lang.String" />
<arg column="PASSWORD" jdbcType="VARCHAR" javaType="java.lang.String" />
<arg column="PHONE" jdbcType="VARCHAR" javaType="java.lang.String" />

<arg column="MODIFIED_BY" jdbcType="CHAR" javaType="java.lang.String" />
<arg column="TOKEN" jdbcType="VARCHAR" javaType="java.lang.String" />
</constructor>
</resultMap>
…………
</mapper>
5.调用
@Autowired
@Resource(name = "db1Template")
private SqlSessionTemplate sqlSessionTemplate;
public Test getTest(Long id) {
return sqlSessionTemplate.selectOne("com.example.demo.mybatis.dbs.db1.dao.UserMapper.getuser",id);
}
注意：
2、3注意路径， 不需要dao层
