Spring--ssm整合(分)

1      导入jar

导入spring(包含springmvc)，mybatis，mybatis-spring整合。数据库驱动，jstl，c3p0管理数据源，log4j.

 

 

 

 

 

 

2      配置web.xml入门文件

2.1  图解

 

2.2  加载Spring容器

<!-- 1.Spring容器 applicationContext.xml -->   <context-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath*:applicationContext-*.xml</param-value>   </context-param>    <listener>      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>   </listener>

2.3  加载springmvc.xml

<!-- 2.Springmvc 前端控制器 -->      <!-- 2.1 加载  springmvc.xml -->   <servlet>      <servlet-name>springDispatcherServlet</servlet-name>      <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>      <init-param>         <param-name>contextConfigLocation</param-name>         <param-value>classpath:springmvc.xml</param-value>      </init-param>      <load-on-startup>1</load-on-startup>   </servlet>       <!-- 2.2 设置请求url -->   <servlet-mapping>      <servlet-name>springDispatcherServlet</servlet-name>      <url-pattern>*.do</url-pattern>   </servlet-mapping>        <!-- 2.3 restful风格，过滤.do -->   <servlet-mapping>      <servlet-name>springDispatcherServlet</servlet-name>      <url-pattern>/rest/*</url-pattern>   </servlet-mapping> 

2.4  编码过滤—springMVC自带

<!-- 3.编码过滤 -->   <filter>      <filter-name>characterEncoding</filter-name>      <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>      <init-param>         <param-name>encoding</param-name>         <param-value>UTF-8</param-value>      </init-param>   </filter>    <filter-mapping>      <filter-name>characterEncoding</filter-name>      <url-pattern>/*</url-pattern>   </filter-mapping>

2.5  Restfull处理各种类型请求转换

<!-- 4、使用Rest风格的URI，将页面普通的post请求转为指定的delete或者put请求 -->   <filter>      <filter-name>HiddenHttpMethodFilter</filter-name>      <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>   </filter>   <filter-mapping>      <filter-name>HiddenHttpMethodFilter</filter-name>      <url-pattern>/*</url-pattern>   </filter-mapping>   <filter>      <filter-name>HttpPutFormContentFilter</filter-name>      <filter-class>org.springframework.web.filter.HttpPutFormContentFilter</filter-class>   </filter>   <filter-mapping>      <filter-name>HttpPutFormContentFilter</filter-name>      <url-pattern>/*</url-pattern>   </filter-mapping>

3      springmvc.xml

3.1  图解

3.2  全局扫描—只扫描@Controller

<!-- 1. 扫描 -->   <context:component-scan base-package="com.lan" use-default-filters="false">      <!--只扫描控制器。@Controller -->   </context:component-scan>

3.3  映射器适配器，处理json

 

<!--2. 两个标准配置 -->   <!-- 将springmvc不能处理的请求交给tomcat -->   <mvc:default-servlet-handler />   <!-- 能支持springmvc更高级的一些功能，JSR303校验，快捷的ajax...映射动态请求 -->   <mvc:annotation-driven />

3.4  视图解析器

<!--3. 配置视图解析器，方便页面返回 --><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"><property name="prefix" value="/WEB-INF/views/"></property><property name="suffix" value=".jsp"></property></bean>

4      applicationContext-dao.xml

4.1  图解

 

4.2  全局扫描--无

4.3  数据源

4.3.1  db.properties

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/e3mall-32?characterEncoding=utf-8jdbc.driverClass=com.mysql.jdbc.Driverjdbc.user=rootjdbc.password=root

4.3.2  引入、加载数据源 alibaba

<!-- 2.数据源 --><!-- 2.1 引入--><context:property-placeholder location="classpath:db.properties" /><!-- 2.2 加载 --><bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">   <property name="url" value="${jdbc.jdbcUrl}"></property>   <property name="driverClassName" value="${jdbc.driverClass}"></property>   <property name="username" value="${jdbc.user}"></property>   <property name="password" value="${jdbc.password}"></property>   <property name="maxActive" value="10" />   <property name="minIdle" value="5" /></bean>

4.4  sqlSessionFactory

4.4.1  第一种

<!-- 3.sqlSessionFactory 配置和MyBatis的整合 -->         <beanid="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean">                   <!--3.1注入数据源 -->                   <propertyname="dataSource" ref="dataSource"></property>                    <!--3.2  指定mybatis   全局配置文件  -->                   <propertyname="configLocation" value="classpath:sqlMapConfig.xml"></property>                    <!--3.3指定mybatis，mapper文件的位置 -->                   <propertyname="mapperLocations"value="classpath:mapper/*.xml"></property>         </bean>

4.4.2  第二种 在同包下

<!--3.sqlSessionFactory 配置和MyBatis的整合 --><bean id="sqlSessionFactory"class="org.mybatis.spring.SqlSessionFactoryBean">   <!-- 3.1注入数据源 -->   <property name="dataSource" ref="dataSource"></property>   <!-- 3.2  指定mybatis   全局配置文件  -->   <property name="configLocation"value="classpath:mybatis/SqlMapConfig.xml"/>   <!-- 3.3指定mybatis，mapper文件的位置-->   <!--<propertyname="mapperLocations"value="classpath:mapper/*.xml"></property>--></bean> 

多一步pom加载xml

 

<build>    <finalName>${project.artifactId}</finalName>    <resources>        <resource>            <directory>src/main/java</directory>            <includes>                <include>**/*.properties</include>                <include>**/*.xml</include>            </includes>            <filtering>false</filtering>        </resource>    </resources></build>

4.5  Mybatis

<!-- 4. 配置mybatis扫描器， --><!-- 4.1 将mybatis接口的实现加入到ioc容器中  dao接口 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">   <property name="basePackage" value="cn.e3mall.mapper"></property>   <!-- 使用sqlSessionFactoryBeanName -->   <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/></bean><!-- 4.2  (可选)配置一个可以执行批量的sqlSession --><bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">   <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"></constructor-arg>   <constructor-arg name="executorType" value="BATCH"></constructor-arg></bean>

5      applicationContext-service.xml

<!-- 配置包扫描器 --><context:component-scan base-package="cn.e3mall.service"/>

6      applicationContext-trans.xml-事务

6.1  xml

<!-- 事务管理器 --><bean id="transactionManager"   class="org.springframework.jdbc.datasource.DataSourceTransactionManager">   <!-- 数据源 -->   <property name="dataSource" ref="dataSource" /></bean><!-- 通知 --><tx:advice id="txAdvice" transaction-manager="transactionManager">   <tx:attributes>      <!-- 传播行为 -->      <tx:method name="save*" propagation="REQUIRED" />      <tx:method name="insert*" propagation="REQUIRED" />      <tx:method name="add*" propagation="REQUIRED" />      <tx:method name="create*" propagation="REQUIRED" />      <tx:method name="delete*" propagation="REQUIRED" />      <tx:method name="update*" propagation="REQUIRED" />      <tx:method name="find*" propagation="SUPPORTS" read-only="true" />      <tx:method name="select*" propagation="SUPPORTS" read-only="true" />      <tx:method name="get*" propagation="SUPPORTS" read-only="true" />   </tx:attributes></tx:advice><!-- 切面 --><aop:config>   <aop:advisor advice-ref="txAdvice"      pointcut="execution(* cn.e3mall.service..*.*(..))" /></aop:config>

6.2  注解

<!-- 5.事务控制 --><!-- 5.1 声明事务 --><bean id="transactionManager"class="org.springframework.jdbc.datasource.DataSourceTransactionManager"><!--注入数据源 --><property name="dataSource" ref="dataSource"></property></bean><!-- 5.2 开启事务注解 --><tx:annotation-driven transaction-manager="transactionManager" />

 

7      SqlMapConfig.xml—全局配置文件

 

<!-- 1.驮峰式命名规则 -->   <settings>      <setting name="mapUnderscoreToCamelCase" value="true" />   </settings>    <!-- 2.ognl实例类的别名 -->   <typeAliases>      <package name="com.lan.pojo" />   </typeAliases>    <!-- 3.（可选扩展）注册分页插件 -->   <plugins>      <plugin interceptor="com.github.pagehelper.PageInterceptor"></plugin>   </plugins>
