spring-mabatis整合的配置文件

1.spring.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:p="http://www.springframework.org/schema/p"
     xmlns:context="http://www.springframework.org/schema/context"
     xmlns:jee="http://www.springframework.org/schema/jee" xmlns:tx="http://www.springframework.org/schema/tx"
     xmlns:aop="http://www.springframework.org/schema/aop"
     xmlns:jaxws="http://cxf.apache.org/jaxws"
     xsi:schemaLocation="
             http://www.springframework.org/schema/beans
             http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
             http://www.springframework.org/schema/context
             http://www.springframework.org/schema/context/spring-context-3.0.xsd
             http://www.springframework.org/schema/jee
             http://www.springframework.org/schema/jee/spring-jee-3.0.xsd
             http://www.springframework.org/schema/tx
             http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
             http://www.springframework.org/schema/aop
             http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
             http://cxf.apache.org/jaxws
             http://cxf.apache.org/schemas/jaxws.xsd">
     <!-- *************************导cxf的配置文件*************************** -->
     <!-- 引入属性文件 -->
     <context:property-placeholder location="classpath:config.properties"/>

     <!-- 自动扫描(自动注入) -->
     <context:component-scan base-package="sy.*"></context:component-scan>

 </beans>
     

spring.xml

<context:property-placeholder location="classpath:config.properties"/>

自动引入配置文件

<context:component-scan base-package="sy.*"></context:component-scan>

自动扫描sy下的所有类，不需要再配置<beans id...>

2.spring-mybatis.xml

大部分代码都有注释，就不再一一说明了。

3.所需jar包

 <dependencies>
         <dependency>
             <groupId>org.springframework</groupId>
             <artifactId>spring-core</artifactId>
             <version>4.0.6.RELEASE</version>
         </dependency>
         <dependency>
             <groupId>org.mybatis</groupId>
             <artifactId>mybatis</artifactId>
             <version>3.2.7</version>
         </dependency>
         <dependency>
             <groupId>org.mybatis</groupId>
             <artifactId>mybatis-spring</artifactId>
             <version>1.1.1</version>
         </dependency>
         <dependency>
             <groupId>mysql</groupId>
             <artifactId>mysql-connector-java</artifactId>
             <version>5.1.32</version>
         </dependency>
     </dependencies>

此处是以maven形式给出的，其实都可以自己一一下载，下载方式：

下载地址：http://search.maven.org/

搜索对应的artifactId即可
