springboot配置双数据源 MySQL和SqlServer

 

1. pom文件的驱动jar包加上去，

compile 'com.microsoft.sqlserver:mssql-jdbc:6.2.2.jre8'

2. application.yml 

spring:
datasource:
master:
jdbc-url: jdbc:mysql://10.12.49.55:3306/smartcity-01

username: root
password: root
# 使用druid数据源
type: com.alibaba.druid.pool.DruidDataSource
driverClassName: com.mysql.jdbc.Driver
other:
jdbc-url: jdbc:sqlserver://10.12.49.35:1433;DatabaseName=LandscapingDB

username: sa
password: Sql123
#使用druid数据源
type: com.alibaba.druid.pool.DruidDataSource
driverClassName: com.microsoft.sqlserver.jdbc.SQLServerDriver

 

注意不要使用url，要使用jdbc-url

 

主数据库配置：

package com.pactera.scm.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.jdbc.datasource.DataSourceTransactionManager;
import javax.sql.DataSource;
@Configuration
@MapperScan(basePackages ="com.pactera.scm.mapper", sqlSessionFactoryRef = "masterSqlSessionFactory")
public class MybatisDbMasterConfig {
@Primary
@Bean(name = "masterDataSource")
@ConfigurationProperties(prefix = "spring.datasource.master")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
@Primary
@Bean(name = "masterSqlSessionFactory")
public SqlSessionFactory sqlSessionFactory(@Qualifier("masterDataSource") DataSource dataSource) throws Exception {
SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
factoryBean.setDataSource(dataSource);
factoryBean.setTypeAliasesPackage("com.pactera.scm.entity");
factoryBean.setMapperLocations(
new PathMatchingResourcePatternResolver().getResources("classpath:mapper/*.xml"));
return factoryBean.getObject();
}
@Primary
@Bean(name = "masterTransactionManager")
public DataSourceTransactionManager transactionManager(@Qualifier("masterDataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "masterSqlSessionTemplate")
@Primary
public SqlSessionTemplate testSqlSessionTemplate(
@Qualifier("masterSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}

　　第二数据库配置：

package com.pactera.scm.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.jdbc.datasource.DataSourceTransactionManager;
import javax.sql.DataSource;
@Configuration
@MapperScan(basePackages = "com.pactera.scm.otherDB", sqlSessionFactoryRef = "otherSqlSessionFactory")
public class MybatisDbOtherConfig {
@Bean(name = "otherDataSource")
@ConfigurationProperties(prefix = "spring.datasource.other")
public DataSource dataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "otherTransactionManager")
public DataSourceTransactionManager transactionManager(@Qualifier("otherDataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "otherSqlSessionFactory")
public SqlSessionFactory basicSqlSessionFactory(@Qualifier("otherDataSource") DataSource basicDataSource) throws Exception {
SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
factoryBean.setDataSource(basicDataSource);
factoryBean.setMapperLocations(
new PathMatchingResourcePatternResolver().getResources("classpath:other/*.xml"));
return factoryBean.getObject();
}
@Bean(name = "otherSqlSessionTemplate")
public SqlSessionTemplate testSqlSessionTemplate(
@Qualifier("otherSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}

　　

启动类正常些就行了，不需要改动，保证能扫描到配置文件就行
@SpringBootApplication
@EnableConfigurationProperties
@EnableScheduling
public class ScmApplication {
public static void main(String[] args) {
SpringApplication.run(ScmApplication.class, args);
}
}
使用：
@Resource
private AccountMapper accountMapper;
直接调用就行
