spring整合springmvc和mybatis【jar,xml】

1.spring

1.1 jar包

 

 1.2 spring基本配置，包扫描注解

    <!-- 自动扫描 -->
    <context:component-scan base-package="com.getword">
        <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

 

 

2 mybatis

2.1 jar包

额外的jar包：

cjlib字节码增强、fileupload、io增强等

 

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"

    <!-- mybatis:scan会扫描com.getword.dao包里的所有接口当作Spring的bean配置，之后可以进行依赖注入-->
    <mybatis:scan base-package="com.getword.dao"/>

    <!-- 扫描com.getword包下面的java文件，有Spring的相关注解的类，则把这些类注册为Spring的bean -->
    <!--<context:component-scan base-package="com.getword"/>-->

    <!-- 自动扫描 -->
    <context:component-scan base-package="com.getword">
        <!-- 扫描时跳过 @Controller 注解的JAVA类（控制器） -->
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!-- 使用PropertyOverrideConfigurer后处理器加载数据源参数 -->
    <context:property-override location="classpath:db.properties"/>

    <!-- 配置c3p0数据源 -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource"/>

    <!-- 2.配置sqlsessionfactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--注入数据源-->
        <property name="dataSource" ref="dataSource"></property>
        <!-- 设置mybatis配置文件路径 -->
        <!--<property name="configLocation" value="classpath:mybatis-config.xml"></property>-->
    </bean>

    <!-- JDBC事务管理器 -->
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
          p:dataSource-ref="dataSource"/>

    <!-- 启用支持annotation注解方式事务管理 -->
    <tx:annotation-driven transaction-manager="transactionManager"  proxy-target-class="true"/>


    <!---文件下载，处理器-->
    <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="defaultEncoding" value="UTF-8"/>
        <!-- maxUploadSize设置-1 不限制文件大小 -->
        <property name="maxUploadSize" value="-1"/>
    </bean>

</beans>

 

 

 

 3 spring mvc 

3.1 fastjson的使用

配置：

   <!-- 设置配置方案 -->
    <mvc:annotation-driven>
        <!-- 设置不使用默认的消息转换器 -->
        <mvc:message-converters register-defaults="false">
            <!-- 配置Spring的转换器 -->
            <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.xml.XmlAwareFormHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.ByteArrayHttpMessageConverter"/>
            <bean class="org.springframework.http.converter.BufferedImageHttpMessageConverter"/>
            <!-- 配置fastjson中实现HttpMessageConverter接口的转换器 -->
            <bean id="fastJsonHttpMessageConverter"
                  class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
                <!-- 加入支持的媒体类型：返回contentType -->
                <property name="supportedMediaTypes">
                    <list>
                        <!-- 这里顺序不能反，一定先写text/html,不然ie下会出现下载提示 -->
                        <value>text/html;charset=UTF-8</value>
                        <value>application/json;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

 

对于返回String类型的数据乱码：

<!-- 配置Spring的转换器, 字符编码 -->
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <constructor-arg value="UTF-8" index="0"/>
                <property name="supportedMediaTypes">
                    <list>
                        <value>text/plain;charset=UTF-8</value>
                    </list>
                </property>
            </bean>
