上篇文章中，我们完成了在OSGI应用中整合Spring和Mybatis框架的准备工作，本节我们继续Spring和Mybatis框架的整合。

一、解决OSGI整合Spring中的Placeholder问题

使用Spring框架的朋友应该都知道，我们可以在Bean的配置文件中，使用${key}的形式访问properties文件中对应的value值，需要用到Spring中的PropertyPlaceholderConfigurer类，使用方式如下，首先需要配置placeholder，例如：

<bean id="placeholder"class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="location">
     <value>conf/jdbc.properties</value>
   </property>
</bean>

conf/jdbc.properties文件内容如下：

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost/mysqldb?useUnicode=true&amp;characterEncoding=UTF-8&amp;
jdbc.username=root
jdbc.password=123456

然后我们定义Bean的时候，就可以使用${key}的方式访问jdbc.properties文件中的内容，例如：

<bean id="dataSource"class="org.apache.commons.dbcp.BasicDataSource"destroy-method="close">
  <property name="driverClassName"value="${jdbc.driverClassName}" />
  <property name="url" value="${jdbc.url}" />
  <property name="username" value="${jdbc.username}"/>
  <property name="password"value="${jdbc.password}" />
</bean>

但是在OSGI应用中，并没有全局的Classpath的概念，其中一个Bundle的属性文件在其他Bundle中无法访问，而且不同Bundle中的ApplictionContext也是独立的，PropertyPlaceholderConfigurer实例在不同的Bundle中不是共享的，所以Spring框架中的Placeholder配置也就存在一定的问题。

Gemini Blueprint为OSGI应用中使用Placeholder提供了一种解决方案，但是基于Key-Value的配置信息需要定义在XML文件中，例如：

<?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:osgix="http://www.springframework.org/schema/osgi-compendium"
   xmlns:ctx="http://www.springframework.org/schema/context"
   xmlns:osgi="http://www.eclipse.org/gemini/blueprint/schema/blueprint"
   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/osgi-compendium 
      http://www.springframework.org/schema/osgi-compendium/spring-osgi-compendium.xsd
      http://www.eclipse.org/gemini/blueprint/schema/blueprint 
       http://www.eclipse.org/gemini/blueprint/schema/blueprint/gemini-blueprint.xsd">

   <osgix:cm-properties id="dbInfo" persistent-id="com.csdn.osgi.common">
      <prop key="driver">com.mysql.jdbc.Driver</prop>
      <prop key="url">jdbc:mysql://127.0.0.1:3306/osgi</prop>
      <prop key="username">root</prop>
      <prop key="password"></prop>
   </osgix:cm-properties>

   <ctx:property-placeholder properties-ref="dbInfo" />

</beans>

接下来在Bean的定义中，就可以一${Key}的形式访问Value值了，例如：

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">         
        <property name="driverClassName" value="${driver}" />  
        <property name="url" value="${url}" />  
        <property name="username" value="${username}" />     
        <property name="password" value="${password}" />        
    </bean>

二、Spring与Mybatis框架整合

1、首先新建一个Plug-in Project,名称为com.csdn.osgi.database，该Bundle用于操作数据库。

2、接着在com.csdn.osgi.database工程中新建META-INF/spring目录，然后在该目录下新建database.xml文件，用于配置数据源及Mybatis-Spring插件提供的SqlSessionFactoryBean和SqlSessionTemplate的实例，以及事务管理器等。
database.xml文件内容如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">


    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">         
        <property name="driverClassName" value="${driver}" />  
        <property name="url" value="${url}" />  
        <property name="username" value="${username}" />     
        <property name="password" value="${password}" />        
    </bean>   

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 
      <property name="dataSource" ref="dataSource" /> 
      <property name="configLocation" value="classpath:sqlMap.xml"/>
    </bean>

    <!-- 创建SqlSessionTemplate -->
    <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> 
      <constructor-arg index="0" ref="sqlSessionFactory" /> 
    </bean>

    <!-- 事务管理 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">  
        <property name="dataSource" ref="dataSource" />  
    </bean> 

    <!--事务模板 -->  
    <bean id="transactionTemplate" class="org.springframework.transaction.support.TransactionTemplate">  
        <property name="transactionManager">  
            <ref local="transactionManager" />  
        </property>  
        <!--ISOLATION_DEFAULT 表示由使用的数据库决定  -->  
        <property name="isolationLevelName" value="ISOLATION_DEFAULT"/>  
        <property name="propagationBehaviorName" value="PROPAGATION_REQUIRED"/>
    </bean>  
</beans>

3、接下来在META-INF/spring目录下，新建一个dmconfig.xml文件，用于配置placeholder及注册sqlSessionTemplate这个Bean，这样在其他Bundle中就可以通过引用我们注册的sqlSessionTemplate来操作数据库了。
dmconfig.xml文件内容如下：

<?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:osgix="http://www.springframework.org/schema/osgi-compendium"
   xmlns:ctx="http://www.springframework.org/schema/context"
   xmlns:osgi="http://www.eclipse.org/gemini/blueprint/schema/blueprint"
   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/osgi-compendium 
      http://www.springframework.org/schema/osgi-compendium/spring-osgi-compendium.xsd
      http://www.eclipse.org/gemini/blueprint/schema/blueprint 
       http://www.eclipse.org/gemini/blueprint/schema/blueprint/gemini-blueprint.xsd">

   <osgix:cm-properties id="dbInfo" persistent-id="com.csdn.osgi.common">
      <prop key="driver">com.mysql.jdbc.Driver</prop>
      <prop key="url">jdbc:mysql://127.0.0.1:3306/osgi</prop>
      <prop key="username">root</prop>
      <prop key="password"></prop>
   </osgix:cm-properties>

   <ctx:property-placeholder properties-ref="dbInfo" />

   <osgi:service id="sqlMapService" ref="sqlSessionTemplate" interface="org.apache.ibatis.session.SqlSession" />
</beans>

4、接下来就是Mybatis主配置文件和SQL的配置了，在sqlSessionFactory这个Bean的配置中，我们指定了Mybatis配置文件为sqlMap.xml，如下：

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> 
      <property name="dataSource" ref="dataSource" /> 
      <property name="configLocation" value="classpath:sqlMap.xml"/>
    </bean>

所以需要在com.csdn.osgi.database工程的src目录下新建一个sqlMap.xml文件，内容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
    PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
    "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <mappers>
        <mapper resource="user.xml"/>
    </mappers>
</configuration>

上面配置中，我们指定了SQL配置文件为user.xml，接着在com.csdn.osgi.database工程的src目录下新建user.xml文件，内容如下：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="user">
    <insert id="saveUser" parameterType="java.util.HashMap">
        insert into user(username,password) values(#{UserName},#{Password});
    </insert>

    <select id="getPasswordByName" parameterType="java.lang.String" resultType="java.lang.String">
        select password from user where username = #{UserName}
    </select>
</mapper>

5、整个工程目录及文件结构如下图所示：
这里写图片描述
6、然后还需要对com.csdn.osgi.database工程的MANIFEST.MF文件新建修改，添加如下Bundle的依赖：

Manifest-Version: 1.0
Bundle-ManifestVersion: 2
Bundle-Name: Database
Bundle-SymbolicName: com.csdn.osgi.database
Bundle-Version: 1.0.0.qualifier
Bundle-Vendor: CSDN
Bundle-RequiredExecutionEnvironment: JavaSE-1.8
Require-Bundle: org.springframework.jdbc;bundle-version="3.0.0",
 org.mybatis.mybatis;bundle-version="3.1.1",
 com.springsource.org.apache.commons.dbcp;bundle-version="1.2.2",
 com.springsource.org.apache.commons.pool;bundle-version="1.3.0",
 org.springframework.transaction;bundle-version="3.0.0",
 com.springsource.com.mysql.jdbc;bundle-version="5.1.6",
 org.mybatis.mybatis-spring;bundle-version="1.2.3"

上面MANIFEST.MF文件中，Require-Bundle元数据头为新增。

7、最后一步，启动OSGI容器。需要单击Run=>Debug Configurations…菜单，如下图所示：
这里写图片描述

单击Validate Bundles按钮，查看是否存在Bundle依赖问题，笔者单击后如下图所示：
这里写图片描述

说明存在依赖问题，解决方法非常简单，单击面板上的Add Required Bundles按钮即可。

启动后输出控制台输出日志内容如下：

从日志文件中可以分析出，Mybatis相关的Bean已经实例化成功，本节内容先介绍这么多，下篇文件中我们在其他Bundle中通过Mybatis-Spring插件提供的模版类操作数据库。

注意：上篇文章提到使用Mybatis-Spring插件版本为1.2.0，与Spring 3.0整合存在一定的问题，本文中笔者將Mybatis-Spring插件版本改为1.2.3。
