spring sprinMVC mybitas 一起玩耍

小黑哎代码

分析：MVC
1. SpringMVC：控制器配置用注解
扫描包，视图解析器，开启注解支持，静态资源不过滤

2. MyBatis：它的SqlMapConfig.xml最后就没了（内容都挪到spring的配置文件中）
它的XXXDao.xml全用注解配置
Spring整合Mybatis关键点： 把Mybatis的SqlSessionFactory对象的创建交给Spring管理。
那么问题来了 mvc 的配置文件在哪加载 spring的配置文件在哪加载 mybitas的dao 在哪扫描 控制器又在哪扫描 service 又在哪扫描
废话不多说直接上代码

从上面的web.xml 可以看到 mvc 的配置文件是通过 配置disoatcherServlet初始化参数 来加载的spring的配置文件是通过ContextLoaderListener加载的
哪好spring springMVC 配置文件都有地方加载了 哪mybiats在哪加载呢？惯例 上代码
applicationContext.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
>


<!--1. 开启注解扫描，扫描service包下的注解-->
<
context
:component-scan
base-package
="cn.lixin.service"
></
context
:component-scan
>


<!--2. 加载jdbc.properties配置文件-->
<
context
:property-placeholder
location
="classpath:jdbc.properties"
></
context
:property-placeholder
>


<!--3. 创建连接池-->
<
bean
id
="dataSource"
class
="com.alibaba.druid.pool.DruidDataSource"
>

<
property
name
="driverClassName"
value
="${jdbc.driver}"
></
property
>

<
property
name
="url"
value
="${jdbc.url}"
></
property
>

<
property
name
="username"
value
="${jdbc.username}"
></
property
>

<
property
name
="password"
value
="${jdbc.password}"
></
property
>

<
property
name
="initialSize"
value
="${jdbc.initialSize}"
></
property
>

<
property
name
="maxActive"
value
="${jdbc.maxActive}"
></
property
>


</
bean
>

<!--4. Spring整合Mybatis，把SqlSession的工厂交给Spring管理-->
<
bean
id
="sqlSessionFactory"
class
="org.mybatis.spring.SqlSessionFactoryBean"
>

<
property
name
="dataSource"
ref
="dataSource"
></
property
>

<!--配置分页框架属性-->
<
property
name
="plugins"
>

<
array
>

<
bean
class
="com.github.pagehelper.PageInterceptor"
>

<
property
name
="properties"
>

<
props
>

<
prop
key
="helperDialect"
>
mysql
</
prop
>

<
prop
key
="reasonable"
>
true
</
prop
>

</
props
>

</
property
>

</
bean
>

</
array
>

</
property
>

</
bean
>

<!--5. 包扫描器，扫描.dao包下的所有dao的接口-->
<
bean
class
="org.mybatis.spring.mapper.MapperScannerConfigurer"
>

<
property
name
="basePackage"
value
="cn.lixin.dao"
></
property
>

</
bean
>


<!--6. 配置Spring提供的事务管理器-->
<
bean
id
="transactionManager"
class
="org.springframework.jdbc.datasource.DataSourceTransactionManager"
>

<
property
name
="dataSource"
ref
="dataSource"
></
property
>

</
bean
>


<!--7. 开启声明式事务的注解支持-->
<
tx
:annotation-driven
transaction-manager
="transactionManager"
></
tx
:annotation-driven
>

<!--导入SpringSecurity文件-->
<
import
resource
="classpath:springSecurity.xml"
></
import
>

</
beans
>

从上面的配置文可以看到
<!--2. 加载jdbc.properties配置文件-->
<!--3. 创建连接池-->

<!--4. Spring整合Mybatis，把SqlSession的工厂交给Spring管理-->
<!--5. 包扫描器，扫描.dao包下的所有dao的接口-->

<!--6. 配置Spring提供的事务管理器-->
Mybatis 配置文件的事情都可以在spring配置文件里面完成到此spring springMVC mybitas 是不是可以一起玩耍了
下面提供一下我的pom.xml 的依赖
