MYBATIS,SPRING,SPRINGMVC three-frame SSM integration Template

Integration steps

• Create a Web project
• Import all the jar packages required for consolidation
• Write the required configuration files for each layer

1) MyBatis Global configuration file

<configuration>

<!--batch alias settings--
<typeAliases>
<package name= "Cn.ssm.pojo"/>
</typeAliases>

</configuration>

2) Spring Management MyBatis configuration file

<!--loading external resource files--
<context:property-placeholder location= "Classpath:db.properties"/>

<!--managing Data sources--
<bean id= "DataSource" class= "Org.apache.commons.dbcp.BasicDataSource" >
<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>

<!--management Sqlsessionfactory--
<bean id= "Sqlsessionfactory" class= "Org.mybatis.spring.SqlSessionFactoryBean" >
<!--injecting data sources--
<property name= "DataSource" ref= "DataSource"/>
<!--load the global configuration file for MyBatis--
<property name= "configlocation" value= "Classpath:mybatis/sqlmapconfig.xml"/>
</bean>

<!--managing bulk agent Objects--
<bean class= "Org.mybatis.spring.mapper.MapperScannerConfigurer" >
<!--Scan Package--
<property name= "Basepackage" value= "Cn.ssm.mapper"/>
</bean>

3) Manage Service

<!--Manage all service--
<context:component-scan base-package= "Cn.ssm.service"/>

4) Management Services

<!--configuration Transaction Manager-
<bean id= "TransactionManager" class= "Org.springframework.jdbc.datasource.DataSourceTransactionManager" >
<!--injecting data sources--
<property name= "DataSource" ref= "DataSource"/>
</bean>

<!--notice--
<tx:advice id= "Txadvice" transaction-manager= "TransactionManager" >
<tx:attributes>
<tx:method name= "insert*" propagation= "REQUIRED"/>
<tx:method name= "update*" propagation= "REQUIRED"/>
<tx:method name= "delete*" propagation= "REQUIRED"/>

<tx:method name= "query*" propagation= "SUPPORTS" read-only= "true"/>
</tx:attributes>
</tx:advice>

<!--configuring AOP--
<aop:config>
<aop:advisor advice-ref= "Txadvice" pointcut= "Execution (* cn.ssm.service.*.* (..))" />
</aop:config>

5) SPRINGMVC's core configuration file

<!--1, configure the scanner, scan the annotated class with @controller and be maintained by the Spring bean container-
<context:component-scan base-package= "Cn.ssm.controller"/>
<!--2, note driver: Simple configuration, can load type converter, validator, JSON parser--
<mvc:annotation-driven conversion-service= "Conversionservice"/>
<!--Configuration type converters--
<bean id= "Conversionservice" class= "Org.springframework.context.support.ConversionServiceFactoryBean" >
<property name= "Converters" >
<set>
<bean class= "Cn.ssm.utils.converter.CustomParamsConverter"/>
</set>
</property>
</bean>
<!--3, configure view resolver--
<bean class= "Org.springframework.web.servlet.view.InternalResourceViewResolver" >
<property name= "prefix" value= "/web-inf/jsp/"/>
<property name= "suffix" value= ". jsp"/>
</bean>
<!--4, load other configuration files--
<import resource= "Classpath:spring/applicationcontext-*.xml"/>

6) Web. xml file

<!--Configure the SPRINGMVC Front Controller--
<servlet>
<servlet-name>ssm</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<!--load Springmvc's core profile--
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<!--initialize the SPRINGMVC framework with the Web container started--
<load-on-startup>1</load-on-startup>
</servlet>

<!--Configure access-blocking URLs .action-->
<servlet-mapping>
<servlet-name>ssm</servlet-name>
<!--*.action: Block all URLs ending with action/: Yes, SPRINGMVC restful style struts2:/*: Block all (JSP 404)--
<url-pattern>*.action</url-pattern>
</servlet-mapping>

<!--Configure garbled filters--
<filter>
<filter-name>CharacterEncodingFilter</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>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

• Introducing Resource Files

1. Connection Database Information Profile Db.properties
2. Log file Log4j.properties
