环境搭建 · BeetlSQL3 官方使用手册

## 环境搭建为了方便快速演示，使用Spring单元测试。在src/test下创建一个java类SimpleTest，如下(所有代码在 https://gitee.com/xiandafu/beetlsql/tree/3.0/sql-integration/sql-spring ) ```java import org.beetl.sql.core.SQLManager; import org.beetl.sql.ext.DBInitHelper; import org.junit.Assert; import org.junit.Before; import org.junit.Test; import org.junit.runner.RunWith; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.test.context.ContextConfiguration; import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; @RunWith(SpringJUnit4ClassRunner.class) @ContextConfiguration(locations = {"classpath*:spring-simple.xml"}) public class SimpleTest { @Autowired SQLManager sqlManager; @Autowired UserService userService; @Before public void init(){ //初始化内存数据库 DBInitHelper.executeSqlScript(sqlManager,"db/schema.sql"); } @Test public void test(){ UserInfo info = new UserInfo(); info.setId(199999l); info.setName("hello"); userService.addUser(info); } } ``` spring-simple.xml 是spring的配置文件，内容如下 ```xml <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd"> <context:annotation-config/> <context:component-scan base-package="org.beetl.sql.ext.spring.test"/> <bean id="dataSource" class="com.zaxxer.hikari.HikariDataSource" destroy-method="close"> <property name="driverClassName" value="org.h2.Driver"></property> <property name="jdbcUrl" value="jdbc:h2:mem:dbtest;DB_CLOSE_ON_EXIT=FALSE"></property> <property name="username" value="sa"></property> <property name="password" value=""></property> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"></property> </bean>  <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>   <bean name="beetlSqlScannerConfigurer" class="org.beetl.sql.ext.spring.BeetlSqlScannerConfigurer">  <property name="basePackage" value="org.beetl.sql.ext.spring"/>  <property name="daoSuffix" value="Mapper"/> <property name="sqlManagerFactoryBeanName" value="sqlManagerFactoryBean"/> </bean> <bean id="sqlManagerFactoryBean" class="org.beetl.sql.ext.spring.SqlManagerFactoryBean"> <property name="cs" > <bean class="org.beetl.sql.ext.spring.SpringConnectionSource"> <property name="masterSource" ref="dataSource"></property>  </bean> </property> <property name="dbStyle"> <bean class="org.beetl.sql.core.db.MySqlStyle"/> </property> <property name="sqlLoader"> <bean class="org.beetl.sql.core.loader.MarkdownClasspathLoader"> <property name="sqlRoot" value="/sql"></property> </bean> </property> <property name="nc"> <bean class="org.beetl.sql.core.UnderlinedNameConversion"/> </property> <property name="interceptors"> <list> <bean class="org.beetl.sql.ext.DebugInterceptor"></bean> </list> </property> </bean> </beans> ``` Spring配置需要配置如下Bean * datasource，这里使用H2库 * beetlSqlScannerConfigurer 用于自动扫描java类，找到Mapper接口，自动为其生成代理类，并注册为Spring Bean * sqlManagerFactoryBean, 定义sqlManager，其中masterSource 关联了我们配置好的datasource UserInfo对象是一个POJO，关联了sys_user表 ```java @Table(name="sys_user") @Data public class UserInfo { @AssignID private Long id; private String name; } ``` UserService是一个Spring的Service，简单的调用`userMapper.insert` ```java @Service @Transactional public class UserService { @Autowired UserMapper userMapper; public void addUser(UserInfo userInfo){ userMapper.insert(userInfo); } } ``` UserMapper是一个BeetlSQL3的Mapper,我们使用BaseMapper提供的内置insert方法操作 ```java public interface UserMapper extends BaseMapper<UserInfo> { } ```
