BeetSql是一個全功能DAO工具, 同時具備Hibernate 優勢 & Mybatis優勢功能,適用於認可以SQL爲中心,同時又需求工具能自動能生成大量經常使用的SQL的應用。html

這幾個依賴都是必須的。web
因爲springboot沒有對 beatlsql的快速啓動裝配,因此須要我本身導入相關的bean,包括數據源,包掃描,事物管理器等。spring
在application加入如下代碼:sql
@Bean(initMethod = "init", name = "beetlConfig") public BeetlGroupUtilConfiguration getBeetlGroupUtilConfiguration() { BeetlGroupUtilConfiguration beetlGroupUtilConfiguration = new BeetlGroupUtilConfiguration(); ResourcePatternResolver patternResolver = ResourcePatternUtils.getResourcePatternResolver(new DefaultResourceLoader()); try { // WebAppResourceLoader 配置root路徑是關鍵 WebAppResourceLoader webAppResourceLoader = new WebAppResourceLoader(patternResolver.getResource("classpath:/templates").getFile().getPath()); beetlGroupUtilConfiguration.setResourceLoader(webAppResourceLoader); } catch (IOException e) { e.printStackTrace(); } //讀取配置文件信息 return beetlGroupUtilConfiguration; } @Bean(name = "beetlViewResolver") public BeetlSpringViewResolver getBeetlSpringViewResolver(@Qualifier("beetlConfig") BeetlGroupUtilConfiguration beetlGroupUtilConfiguration) { BeetlSpringViewResolver beetlSpringViewResolver = new BeetlSpringViewResolver(); beetlSpringViewResolver.setContentType("text/html;charset=UTF-8"); beetlSpringViewResolver.setOrder(0); beetlSpringViewResolver.setConfig(beetlGroupUtilConfiguration); return beetlSpringViewResolver; } //配置包掃描 @Bean(name = "beetlSqlScannerConfigurer") public BeetlSqlScannerConfigurer getBeetlSqlScannerConfigurer() { BeetlSqlScannerConfigurer conf = new BeetlSqlScannerConfigurer(); conf.setBasePackage("com.forezp.dao"); conf.setDaoSuffix("Dao"); conf.setSqlManagerFactoryBeanName("sqlManagerFactoryBean"); return conf; } @Bean(name = "sqlManagerFactoryBean") @Primary public SqlManagerFactoryBean getSqlManagerFactoryBean(@Qualifier("datasource") DataSource datasource) { SqlManagerFactoryBean factory = new SqlManagerFactoryBean(); BeetlSqlDataSource source = new BeetlSqlDataSource(); source.setMasterSource(datasource); factory.setCs(source); factory.setDbStyle(new MySqlStyle()); factory.setInterceptors(new Interceptor[]{new DebugInterceptor()}); factory.setNc(new UnderlinedNameConversion());//開啓駝峯 factory.setSqlLoader(new ClasspathLoader("/sql"));//sql文件路徑 return factory; } //配置數據庫 @Bean(name = "datasource") public DataSource getDataSource() { return DataSourceBuilder.create().url("jdbc:mysql://127.0.0.1:3306/test").username("root").password("123456").build(); } //開啓事務 @Bean(name = "txManager") public DataSourceTransactionManager getDataSourceTransactionManager(@Qualifier("datasource") DataSource datasource) { DataSourceTransactionManager dsm = new DataSourceTransactionManager(); dsm.setDataSource(datasource); return dsm; }
在resouces包下,加META_INF文件夾,文件夾中加入spring-devtools.properties:數據庫
restart.include.beetl=/beetl-2.3.2.jar restart.include.beetlsql=/beetlsql-2.3.1.jar
在templates下加一個index.btl文件。springboot
加入jar和配置beatlsql的這些bean,以及resources這些配置以後,springboot就可以訪問到數據庫類。restful
# DROP TABLE `account` IF EXISTS CREATE TABLE `account` ( `id` int(11) NOT NULL AUTO_INCREMENT, `name` varchar(20) NOT NULL, `money` double DEFAULT NULL, PRIMARY KEY (`id`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8; INSERT INTO `account` VALUES ('1', 'aaa', '1000'); INSERT INTO `account` VALUES ('2', 'bbb', '1000'); INSERT INTO `account` VALUES ('3', 'ccc', '1000');
public class Account { private int id ; private String name ; private double money; getter... setter... }
public interface AccountDao extends BaseMapper<Account> { @SqlStatement(params = "name") Account selectAccountByName(String name); }
接口繼承BaseMapper,就能獲取單表查詢的一些性質,當你須要自定義sql的時候,只須要在resouses/sql/account.md文件下書寫文件:架構
selectAccountByName === *根據name獲account select * from account where name= #name#
其中「=== 」上面是惟一標識,對應於接口的方法名,「* 」後面是註釋,在下面就是自定義的sql語句,具體的見官方文檔。
