关于码云开源项目SpringBootAdmin多数据源配置

SpringBootAdmin是码云上一个以springboot为核心的开源的后台管理系统。

这里是链接地址：点击打开链接

由于是后台系统，应该采用数据库分离，权限，用户，角色和业务模块分开。

新建一个数据库配置文件 MyBatisConfigFilm.java

public class MyBatisConfigFilm{@Bean(name="filmDatasource")@ConfigurationProperties(prefix = "spring.datasource.film")public DataSource dataSource() {System.out.println("======================================"+DataSourceBuilder.create().build());return DataSourceBuilder.create().build();}@Bean(name="filmSqlSessionFactory")public SqlSessionFactory sqlSessionFactoryBean(@Qualifier("filmDatasource") DataSource dataSource) throws SQLException {SqlSessionFactoryBean bean = new SqlSessionFactoryBean();System.out.println("dataSource===================================================="+dataSource());bean.setDataSource(dataSource());bean.setTypeAliasesPackage("com.mys.my.pojo");//分页插件PageHelper pageHelper = new PageHelper();Properties properties = new Properties();properties.setProperty("reasonable", "true");properties.setProperty("supportMethodsArguments", "true");properties.setProperty("returnPageInfo", "check");properties.setProperty("params", "count=countSql");pageHelper.setProperties(properties);//添加插件bean.setPlugins(new Interceptor[]{pageHelper});//添加XML目录ResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();try {

}

@MapperScan(basePackages={"com.mys.my.mapper.fiz"}的配置是扫描配置的dao文件 *.java
bean.setMapperLocations(resolver.getResources("classpath:mapper/fiz/*.xml"));
这个配置是扫描对应的mapper文件 *.xml。
