springboot-mybatis多数据源配置

目录

配置数据库连接池

@Configuration
public class DataSourceConfig {
	//读取application.properties中的配置
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.one")
    DataSource dsOne(){
        return DruidDataSourceBuilder.create().build();
    }
    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.two")
    DataSource dsTwo(){
        return DruidDataSourceBuilder.create().build();
    }
}

为mybatis配置对应的数据库

数据库1

@Configuration
@MapperScan(basePackages = "org.akk.mybatis.mapper1",sqlSessionFactoryRef = "sqlSessionFactory1",sqlSessionTemplateRef ="sqlSessionTemplate1" )
public class MyBatisConfigOne {
    @Resource(name = "dsOne")
    DataSource dsOne;

    @Bean
    SqlSessionFactory sqlSessionFactory1() throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dsOne);
        return sqlSessionFactoryBean.getObject();
    }

    @Bean
    SqlSessionTemplate sqlSessionTemplate1() throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory1());
    }
}

数据库2

@Configuration
@MapperScan(basePackages = "org.akk.mybatis.mapper2",sqlSessionFactoryRef = "sqlSessionFactory2",sqlSessionTemplateRef ="sqlSessionTemplate2" )
public class MyBatisConfigTwo {
    @Resource(name = "dsTwo")
    DataSource dsTwo;

    @Bean
    SqlSessionFactory sqlSessionFactory2() throws Exception {
        SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
        sqlSessionFactoryBean.setDataSource(dsTwo);
        return sqlSessionFactoryBean.getObject();
    }

    @Bean
    SqlSessionTemplate sqlSessionTemplate2() throws Exception {
        return new SqlSessionTemplate(sqlSessionFactory2());
    }
}

想要将接口和xml文件放在一起需要在pom文件中配置

    <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
            <resource><directory>src/main/resources</directory></resource>
        </resources>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
