springboot配置mybatis数据源

1.启动类 得加上扫描包scanBasePackages

@SpringBootApplication(exclude={DataSourceAutoConfiguration.class},scanBasePackages = {"com.fast.framework","com.fast.web"})
    public class FastbootWebApplication {
    
        public static void main(String[] args) {
            SpringApplication.run(FastbootWebApplication.class, args);
        }
    
    }

2.yaml数据源参数，使用的hikari数据库连接池

spring:
      datasource:
        driver-class-name: com.mysql.cj.jdbc.Driver
        type: com.zaxxer.hikari.HikariDataSource
        hikari:
          jdbc-url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=convertToNull&useSSL=true
          username: root
          password: root
          max-lifetime: 1765000
          maximum-pool-size: 15

3.包与数据源对应

@Configuration
    @MapperScan(basePackages = "com.fast.framework.dao", sqlSessionTemplateRef = "sqlSessionTemplatePrimary")
    public class MysqlPrimary {
    
        @Bean(name = "datsourcePrimary")
        @ConfigurationProperties(prefix = "spring.datasource.primary")
        public DataSource primaryDatsource() {
            return DataSourceBuilder.create().build();
        }
    
        @Bean(name = "sqlSessionFactoryPrimary")
        public SqlSessionFactory primarySqlSession(@Qualifier("datsourcePrimary") DataSource dataSource) throws Exception {
            SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
            bean.setDataSource(dataSource);
            bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:/mapper/*.xml"));
            bean.setTypeAliasesPackage("");
            return bean.getObject();
        }
    
        @Bean(name = "sqlSessionTemplatePrimary")
        public SqlSessionTemplate mainsql(@Qualifier("sqlSessionFactoryPrimary") SqlSessionFactory sqlSessionFactory) {
            return new SqlSessionTemplate(sqlSessionFactory);
        }
    
        @Bean(name = "datsourcePrimaryManager")
        public DataSourceTransactionManager primaryTransactionManager(@Qualifier("datsourcePrimary") DataSource dataSource) {
            return new DataSourceTransactionManager(dataSource);
        }
    }

总结：这个如果想配置更多，可以多添加几个类，把数据源和包位置关系配置对就好了。
