Spring + Mybatis + SpringMvc 框架搭建小结

附参考博文地址:http://blog.csdn.net/gebitan505/article/details/44455235

一、maven项目构建（此处暂略）

二、集成Spring与Mybatis

  1. Maven引入需要的jar包——pom.xml

    在pom.xml中配置所需jar包，网上可找到大量范例，此处以笔者构建的项目为例，用时需注意jar包的版本。

    <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  2. 配置数据库连接——jdbc.properties

    此处需要注意数据库名(myhappyfarm)，数据库用户名(root)，密码(“”)，以及字符编码(useUnicode=true&characterEncoding=UTF-8)，以上均以笔者所用框架为例。

    jdbc.driverClass = com.mysql.jdbc.Driver
jdbc.url = jdbc:mysql://localhost:3306/myhappyfarm?useUnicode=true&characterEncoding=UTF-8&zeroDateTimeBehavior=convertToNull
jdbc.username = root
jdbc.password = 
jdbc.minPoolSize=2
jdbc.maxPoolSize=20
jdbc.checkoutTimeout=3000
jdbc.maxStatements=50
jdbc.testConnectionOnCheckin = false
jdbc.idleConnectionTestPeriod = 18000

  3. 配置Spring与Mybatis配置文件——spring-mybatis.xml(命名无所谓)

    <?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" xmlns:task="http://www.springframework.org/schema/task"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="http://www.springframework.org/schema/beans

    default-lazy-init="true">
    <!-- 定时器开关 开始 -->
    <task:annotation-driven />
    <!-- 标注类型 的事务配置 如果使用注解事务。就放开 <tx:annotation-driven /> -->
    <bean
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:jdbc.properties</value>
            </list>
        </property>
        <property name="ignoreUnresolvablePlaceholders" value="true" />
    </bean>
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="driverClassName" value="${jdbc.driverClass}" />
    </bean>
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自动匹配Mapper映射文件 -->
        <!--Remember fucking this!!!  -->
        <property name="mapperLocations" value="classpath:com/happyFarm/mapping/*.xml" />
        <property name="typeAliasesPackage" value="com.happyFarm.model" />
    </bean>
    <!-- 通过扫描的模式，扫描目录在com.lanyuan.mapper目录下，所有的mapper都继承SqlMapper接口的接口， 这样一个bean就可以了 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.happyFarm.dao" />
    </bean>
    <!-- 事务配置 -->
    <bean id="transactionManager"
        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>
    <aop:config>
        <aop:pointcut expression="execution(public * com.happyFarm.service.*Impl.*(..))"
            id="pointcut" />
        <aop:advisor advice-ref="txAdvice" pointcut-ref="pointcut" />
    </aop:config>
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <tx:method name="query*" propagation="REQUIRED" read-only="true" />
            <tx:method name="find*" propagation="REQUIRED" read-only="true" />
            <tx:method name="save*" propagation="REQUIRED" />
            <tx:method name="delete*" propagation="REQUIRED" />
            <tx:method name="add*" propagation="REQUIRED" />
            <tx:method name="modify*" propagation="REQUIRED" />
            <tx:method name="logicDelById" propagation="REQUIRED" />
        </tx:attributes>
    </tx:advice>
    <tx:annotation-driven />
    <!-- 使用Spring组件扫描的方式来实现自动注入bean -->
    <context:component-scan base-package="com.happyFarm.service.impl.**" />
    <!-- 隐式地向 Spring 容器注册 -->
    <context:annotation-config />
</beans>

    • 配置*.Mapper.xml的路径以及实体类路径（这里定义了mapperLocation）

      <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource" />
    <!-- 自动匹配Mapper映射文件 -->
    <property name="mapperLocations" value="classpath:com/happyFarm/mapping/*.xml" />
    <property name="typeAliasesPackage" value="com.happyFarm.model" />
</bean>

    • 注入service层的实现类

      <!-- 使用Spring组件扫描的方式来实现自动注入bean -->
<context:component-scan base-package="com.happyFarm.service.impl.**" />

  4. log4j配置，基本无需改变，通用

    #######################################################################
# Categories and levels

#log4j.appender.stdout=org.apache.log4j.ConsoleAppender
#log4j.appender.stdout.layout=org.apache.log4j.PatternLayout

log4j.category.java.sql = debug

#######################################################################

log4j.appender.FileApp.File=${project}WEB-INF/logs/log
log4j.appender.FileApp.layout=org.apache.log4j.PatternLayout
log4j.appender.FileApp.layout.ConversionPattern=%d{yyyy/MM/dd HH:mm:ss} %5p %c{1}:%L - %m%n
log4j.appender.FileApp.Append=true

  5. 利用MyBatis Generator自动创建代码

    • 所需jar包：
      • mybatis_3.2.7.jar
      • mybatis-generator-core-1.3.2-sources.jar
      • mysql-connector-java-5.1.25-bin.jar

    • generatorConfig.xml

      <?xml version="1.0" encoding="UTF-8"?>  
<!DOCTYPE generatorConfiguration  
      PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"  
      "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <classPathEntry
        location="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\webapp\WEB-INF\lib\mysql-connector-java-5.0.3-bin.jar" />
    <context id="DB2Tables" targetRuntime="MyBatis3">
        <commentGenerator>
            <property name="suppressAllComments" value="true" />
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost:3306/myhappyfarm?useUnicode=true&amp;characterEncoding=UTF-8"
            userId="root" password="">
        </jdbcConnection>

        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <!-- generate Model -->
        <javaModelGenerator targetPackage="com.happyFarm.model"
            targetProject="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <!-- generate xml -->
        <sqlMapGenerator targetPackage="com.happyFarm.mapper"
            targetProject="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <!-- generate Mapper -->
        <javaClientGenerator targetPackage="com.happyFarm.dao"
            targetProject="E:\Documents and Settings\Administrator\workspace\happyFarm\src\main\java" type="XMLMAPPER">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table schema="" tableName="cropbasic" domainObjectName="CropBasic"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="cropgrowthinfo" domainObjectName="CropGrowthInfo"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="cropstoreinfo" domainObjectName="CropStoreInfo"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="friendslist" domainObjectName="FriendsList"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="harvestlist" domainObjectName="HarvestList"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="plantinfo" domainObjectName="PlantInfo"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="seedstoreinfo" domainObjectName="SeedStoreInfo"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="userbasic" domainObjectName="UserBasic"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>

        <table schema="" tableName="userinfo" domainObjectName="UserInfo"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
        </table>
    </context>
</generatorConfiguration>
      • 其中，jdbcConnection为数据库连接配置，需注意用户名密码及编码；
      • javaModelGenerator、sqlMapGenerator、javaClientGenerator分别对应自动生成实体类，*Mapper.xml，以及dao层的文件夹名称
      • table表示表名，以及生成的实体对象名
    • DOS命令行进入lib目录（这里需要注意的是，三个jar包和generatorConfig.xml需要在同一目录下，否则会找不到jar包）
    • 执行java -jar mybatis-generator-core-1.3.1.jar -configfile generatorConfig.xml -overwrite
    • 完成后即可在指定文件夹看到生成的model,dao,以及mapper

  6. 依照写好的dao，实体类等编写相应的service层及实现类，至此完成spring与mybatis整合

  7. 配置springMVC配置文件——spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans    
                        http://www.springframework.org/schema/beans/spring-beans-3.1.xsd

8.配置web.xml文件

        <param-value>classpath:spring-application.xml</param-value>
    </context-param>
    <!-- 编码过滤器 -->
    <filter>
        <filter-name>encodingFilter</filter-name>

        <init-param>
            <param-name>encoding</param-name>

        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>encodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>
    <!-- Spring监听器 -->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <!-- 防止Spring内存溢出监听器 -->

        <!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
        <url-pattern>/</url-pattern>
    </servlet-mapping>
    <welcome-file-list>
        <welcome-file>/index.jsp</welcome-file>
    </welcome-file-list>
</web-app>

至此，完成ssm框架搭建的小结，编码时需注意注解等事项，待补充
