ssm相对标准配置(Spring+springmvc+mybatis)

资源下载:http://download.youkuaiyun.com/detail/zhangpan_soft/9742369

最近在看一些童鞋找ssm的整合,发现,很多网上的都不尽相同,在此我提供一下springmvc的整合思路,

其实说起来是ssm的整合,倒不如说是Spring+mybatis的整合,和spring+springmvc的整合,

首先先说Spring+mybatis的整合,

对于mybatis,我们知道,连接数据库必须要连接池(数据源),所以,第一步配置连接池,mybatis是基于sqlsessionfactory的,所以要配置sqlsessionfactory,要使用mapper文件,所以要配置MapperScanner,

对于事务的控制要给Spring,所以要配置事务,基于注解开发,所以要配置注解扫描

二:Spring和springmvc的整合,基于注解开发,要配置注解扫描,对资源文件不拦截,所以配置静态资源,等等一些其他的,

最后:在web.xml中进行一系列配置,下面附上配置代码和注释,另外附上附件可以下载:

最后说一点,本文为了防止容器污染,在配置中做了特别的处理,这种处理也是Spring官方建议的处理,

spring和mybatis整合的配置,一般命名为spring-application.xml

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

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       http://www.springframework.org/schema/aop/spring-aop.xsd">
    <!-- 加载小配置文件 -->
    <context:property-placeholder location="classpath:db.properties"/>

    <!-- 开启aop，对类代理 -->
    <aop:config proxy-target-class="true"/>

    <!-- 配置注解扫描,防止容器污染,排除Controller注解,切记切记 -->
    <context:component-scan base-package="com.redao.manage">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 配置DataSource(数据源,这里用的是阿里数据源) -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

    <!-- 配置sqlsessionFactroy -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--配置数据源-->
        <property name="dataSource" ref="dataSource"/>
        <!--配置mapper文件路径-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        <!--配置别名所在包-->
        <property name="typeAliasesPackage" value="com.redao.manage.model"/>
    </bean>

    <!-- mapper扫描 -->
    <bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--配置sqlsessionfactory,切记,这里不能用ref,必须用value,值为上面配置的sqlsessionfactory的值-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <property name="basePackage" value="com.redao.manage.dao"/>
    </bean>

    <!-- 事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--配置数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--开启注解控制事务-->
    <tx:annotation-driven transaction-manager="transactionManager"/>

</beans>

2.spring和springmvc整合的配置,一般命名为springmvc.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:mvc="http://www.springframework.org/schema/mvc"
       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/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 注解扫描,注意配置,这里只扫描Controller,防止容器污染,切记,切记,和spring-application.xml进行对比 -->
    <context:component-scan base-package="com.redao.manage" use-default-filters="false">
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 配置json解析 -->
    <mvc:annotation-driven conversion-service="conversionService">
        <mvc:message-converters>
            <bean class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"/>
        </mvc:message-converters>
    </mvc:annotation-driven>

    <!-- 添加转换器 -->
    <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <property name="converters">
            <set>
                <!--这里面是我自己定义的转换器,只要实现converter接口就是转换器-->
                <bean class="com.redao.manage.converter.String2Date"/>
                <bean class="com.redao.manage.converter.String2Long"/>
            </set>
        </property>
    </bean>

    <!-- 解决自动添加前后缀 -->
    <bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--jsp文件防止web-inf下面,为了安全,所以,这里如此配置-->
        <property name="prefix" value="/WEB-INF/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <!-- 全局异常处理器解析器 -->
    <bean class="com.redao.manage.exception.CustomExceptionResolve"/>

    <!--静态资源解析,这里用spring默认就可以-->
    <mvc:default-servlet-handler/>

    <!-- 文件上传 -->
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 设置上传文件的最大尺寸为5MB -->
        <property name="maxUploadSize">
            <value>52428800</value>
        </property>
        <!--设置编码-->
        <property name="defaultEncoding" value="UTF-8"></property>
        <!--设置临时文件存放路径-->
        <property name="uploadTempDir" value="fileUpload/temp"></property>
    </bean>
</beans>

3.web.xml配置

    <load-on-startup>1</load-on-startup>
  </servlet>
