spring5入门（二十三）：整合JUnit

整合JUnit4

• 导入依赖

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-test</artifactId>
    <version>5.3.0</version>
    <scope>test</scope>
</dependency>
<dependency>
    <groupId>junit</groupId>
    <artifactId>junit</artifactId>
    <version>4.12</version>
    <scope>compile</scope>
</dependency>

-测试类

@RunWith(SpringJUnit4ClassRunner.class) //单元测试框架
@ContextConfiguration("classpath:bean1.xml") //加载配置文件
public class JTest4 {
 
    @Autowired
    private UserService userService;
 
    @Test
    public void test1() {
        userService.accountMoney();
    }
}

• bean1.xml

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <!--注入dataSource-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>
 
    <!--创建事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"></property>
    </bean>
 
    <!--开启事务注解-->
    <tx:annotation-driven transaction-manager="transactionManager"></tx:annotation-driven>
</beans>

• 注释TxConfig中的创建事务管理器

//    @Bean
//    public DataSourceTransactionManager getDataSourceTransactionManager(DataSource dataSource) {
//        DataSourceTransactionManager transactionManager = new DataSourceTransactionManager();
//        transactionManager.setDataSource(dataSource);
//        return transactionManager;
//    }

• 控制台
