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;
}複製代碼
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複製代碼
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。bash
# 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');複製代碼
public class Account {
private int id ;
private String name ;
private double money;
getter...
setter...
} 複製代碼
public interface AccountDao extends BaseMapper<Account> {
@SqlStatement(params = "name")
Account selectAccountByName(String name);
}複製代碼
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:restful
selectAccountByName
===
*根據name獲account
select * from account where name= #name#複製代碼
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。
