SpringBoot-整合多数据源

整合多数据源

这里有两种，分包数据源和注解数据源，这里讲分包数据源

配置文件中新增两个数据源

spring.datasource.test1.driverClassName = com.mysql.jdbc.Driver

spring.datasource.test1.url = jdbc:mysql://localhost:3306/test01?useUnicode=true&characterEncoding=utf-8

spring.datasource.test1.username = root

spring.datasource.test1.password = root

spring.datasource.test2.driverClassName = com.mysql.jdbc.Driver

spring.datasource.test2.url = jdbc:mysql://localhost:3306/test02?useUnicode=true&characterEncoding=utf-8

spring.datasource.test2.username = root

spring.datasource.test2.password = root

配置文件中新增两个数据源

@Configuration// 注册到springboot容器中

@MapperScan(basePackages = "com.itmayiedu.user1", sqlSessionFactoryRef = "test1SqlSessionFactory")

publicclass DataSource1Config {

 

      /**

       *

       * @methodDesc: 功能描述:(配置test1数据库)

       * @param: @return

       * @createTime:2017年9月17日下午3:16:44

       * @returnType:@return DataSource

       */

      @Bean(name = "test1DataSource")

      @Primary

      @ConfigurationProperties(prefix = "spring.datasource.test1")

      public DataSource testDataSource() {

            return DataSourceBuilder.create().build();

      }

 

      /**

       */

      @Bean(name = "test1SqlSessionFactory")

      @Primary

      public SqlSessionFactory testSqlSessionFactory(@Qualifier("test1DataSource") DataSource dataSource)

                  throws Exception {

            SqlSessionFactoryBean bean = new SqlSessionFactoryBean();

            bean.setDataSource(dataSource);

//          bean.setMapperLocations(

//                     new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/test1/*.xml"));

            returnbean.getObject();

      }

 

      /**

       */

      @Bean(name = "test1TransactionManager")

      @Primary

      public DataSourceTransactionManager testTransactionManager(@Qualifier("test1DataSource") DataSource dataSource) {

            returnnew DataSourceTransactionManager(dataSource);

      }

 

      @Bean(name = "test1SqlSessionTemplate")

      public SqlSessionTemplate testSqlSessionTemplate(

                  @Qualifier("test1SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {

            returnnew SqlSessionTemplate(sqlSessionFactory);

      }

 

}

创建分包Mapper

public interface User1Mapper {

@Insert("insert into users values(null,#{name},#{age});")

public int addUser(@Param("name") String name, @Param("age") Integer age);

}

启动项目

@ComponentScan(basePackages = "com.itmayiedu")

@EnableAutoConfiguration

publicclass App {

      publicstaticvoid main(String[] args) {

            SpringApplication.run(App.class, args);

      }

}
