Java学习笔记-spring整合mybatis

这个项目就是一个例子，只有添加图书的功能：

项目架构：

resource：

整合流程：

1.pom文件节点，这两个是整合用的，其他节点不再赘述：

 <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis-spring -->
         <dependency>
             <groupId>org.mybatis</groupId>
             <artifactId>mybatis-spring</artifactId>
             <version>1.2.</version>
         </dependency>
         <!-- https://mvnrepository.com/artifact/org.mybatis/mybatis -->
         <dependency>
             <groupId>org.mybatis</groupId>
             <artifactId>mybatis</artifactId>
             <version>3.2.</version>
         </dependency>

如果mybatis用的是3.4.1，那么mybatis-spring版本要用1.3.0

2.applicationContextDay06.xml

 <?xml version="1.0" encoding="UTF-8"?>

        xmlns:aop="http://www.springframework.org/schema/aop"

     <!--.识别jdbc.properties文件-->
     <context:property-placeholder location="classpath:jdbc.properties"/>
     <!--.数据源-->
     <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
         <property name="driverClassName" value="${jdbc.driver}"/>

         </tx:attributes>
     </tx:advice>
     <aop:config>
         <!--切点-->
         <aop:pointcut id="pointcut" expression="execution(* *..day06zhenghe.service.*.*(..))"/>
         <!--顾问-->
         <aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut"/>
     </aop:config>
 </beans>

3.jdbc.properties,这里把四个串配上就行了。

4.mybatis,不用配置environments和mappers了，可以setting和alias，也可以直接干掉这个文件。

5.测试类：

 public class Test20171021 {
     @Test
     public void test01(){
         ApplicationContext ctx=new ClassPathXmlApplicationContext("applicationContextDay06.xml");
         IBookService bookService = (IBookService)ctx.getBean("bookService");
         Book book = new Book();
         book.setBookname("放学后");
         book.setBookprice((double) );
         bookService.addBook(book);
     }
 }
