这几个依赖都是必须的。web
因为springboot没有对 beatlsql的快速启动装配,因此须要我本身导入相关的bean,包括数据源,包扫描,事物管理器等。spring
在application加入如下代码:sql
@Bean(initMethod = "init", name = "beetlConfig")
public BeetlGroupUtilConfiguration getBeetlGroupUtilConfiguration() {
BeetlGroupUtilConfiguration beetlGroupUtilConfiguration = new BeetlGroupUtilConfiguration();
ResourcePatternResolver patternResolver = ResourcePatternUtils.getResourcePatternResolver(new DefaultResourceLoader());
try {
// WebAppResourceLoader 配置root路径是关键
WebAppResourceLoader webAppResourceLoader = new WebAppResourceLoader(patternResolver.getResource("classpath:/templates").getFile().getPath());
beetlGroupUtilConfiguration.setResourceLoader(webAppResourceLoader);
} catch (IOException e) {
e.printStackTrace();
}
//读取配置文件信息
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;
}
//配置包扫描
@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());//开启驼峰
factory.setSqlLoader(new ClasspathLoader("/sql"));//sql文件路径
return factory;
}
//配置数据库
@Bean(name = "datasource")
public DataSource getDataSource() {
return DataSourceBuilder.create().url("jdbc:mysql://127.0.0.1:3306/test").username("root").password("123456").build();
}
//开启事务
@Bean(name = "txManager")
public DataSourceTransactionManager getDataSourceTransactionManager(@Qualifier("datasource") DataSource datasource) {
DataSourceTransactionManager dsm = new DataSourceTransactionManager();
dsm.setDataSource(datasource);
return dsm;
}复制代码
在resouces包下,加META_INF文件夹,文件夹中加入spring-devtools.properties:数据库
restart.include.beetl=/beetl-2.3.2.jar
restart.include.beetlsql=/beetlsql-2.3.1.jar复制代码
在templates下加一个index.btl文件。springboot
加入jar和配置beatlsql的这些bean,以及resources这些配置以后,springboot就可以访问到数据库类。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');复制代码
public class Account {
private int id ;
private String name ;
private double money;
getter...
setter...
}复制代码
public interface AccountDao extends BaseMapper<Account> {
@SqlStatement(params = "name")
Account selectAccountByName(String name);
}复制代码
接口继承BaseMapper,就能获取单表查询的一些性质,当你须要自定义sql的时候,只须要在resouses/sql/account.md文件下书写文件:restful
selectAccountByName
===
*根据name获account
select * from account where name= #name#复制代码
其中“=== ”上面是惟一标识,对应于接口的方法名,“* ”后面是注释,在下面就是自定义的sql语句,具体的见官方文档。
