搭建springmvc+ibatis+velocity工程

 

一、搭建工程

1.  创建空的webapp工程：

在想要创建工程的路径下，打开cmd，输入命令：

mvn archetype:create -DgroupId=com.sw.app -DartifactId=app -DarchetypeArtifactId=maven-archetype-webapp

其中app是工程名称。

-DgroupId=com.sw.app 填入自己的groupId

-DartifactId=app 填入自己的artifactId

-DarchetypeArtifactId=maven-archetype-webapp 表示要生成的工程类型是web工程，这个不做修改。

关于groupId和artifactId的概念，可以阅读如jiangshachina的《Maven入门--概念与实例》：http://www.blogjava.net/jiangshachina/archive/2006/09/01/67080.html。

运行好后，会生成一个基础的web工程。

 

 

2.  补全标准mvn目录：

在src/main/下创建java/com/sw/app/文件夹

在src/下创建test/java/com/sw/app/文件夹，以及test/resources/文件夹

 

 

二、集成springmvc+velocity

1.  引入springmvc的jar包

在pom.xml中加入依赖

<!-- spring --> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring</artifactId>     <version>2.5.4</version> </dependency>   <!-- spring mvc --> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>2.5.4</version> </dependency> <!-- velocity --> <dependency> <groupId>velocity</groupId> <artifactId>velocity-dep</artifactId>  <version>1.4</version> </dependency>

所要依赖jar包的groupId、artifactId和版本号，可以到http://www.mvnrepository.com/ 查询。

 

2.  配置web.xml

    打开src/main/webapp/WEB-INF/web.xml，填入下面的配置：

<?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4"     xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd">       <display-name>app</display-name>       <!-- Welcome page -->     <welcome-file-list>         <welcome-file>index.html</welcome-file>     </welcome-file-list>         <!-- Config file location -->     <context-param>         <param-name>contextConfigLocation</param-name>         <param-value>             classpath:META-INF/spring/**/*.xml         </param-value>     </context-param>       <!-- Spring MVC DispatcherServlet -->     <servlet>         <servlet-name>app</servlet-name>         <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>         <load-on-startup>1</load-on-startup>     </servlet>       <!-- Dispatcher servlet mapping for the main web user interface. -->     <servlet-mapping>         <servlet-name>app</servlet-name>         <url-pattern>*.htm</url-pattern>     </servlet-mapping>       <!-- To support chinese gbk encoding -->     <filter>         <filter-name>CharacterSetEncoding Filter</filter-name>         <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>         <init-param>             <param-name>encoding</param-name>             <param-value>GBK</param-value>         </init-param>         <init-param>             <param-name>forceEncoding</param-name>             <param-value>true</param-value>         </init-param>     </filter>     <filter-mapping>         <filter-name>CharacterSetEncoding Filter</filter-name>         <url-pattern>/*</url-pattern>     </filter-mapping>         <!--Spring ApplicationContext -->     <listener>         <listener-class>             org.springframework.web.context.ContextLoaderListener         </listener-class>     </listener>   </web-app>

    其中app是工程名称。

3.  补全spring目录：

在src/main/resources下创建META-INF/spring文件夹

 

4.  添加app-servlet.xml文件

app是工程名称，在src/main/webapp/WEB-INF文件夹下创建app-servlet.xml文件，填入如下配置：

<?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"     xsi:schemaLocation="         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans-2.5.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context-2.5.xsd">       <!-- Autodetect POJOs labeled with the @RequestMapping annotation -->     <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />         <!-- Autodetect methods labeled with the @RequestMapping annotation -->     <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />         <!-- Autodetect POJOs labeled with the @Controller annotation -->     <context:component-scan base-package="com.sw" />       <!-- Configurer that sets up a shared VelocityEngine for Velocity views -->     <bean id="velocityConfigurer"         class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">         <property name="velocityProperties">             <props>                 <prop key="input.encoding">GBK</prop>                 <prop key="output.encoding">GBK</prop>             </props>         </property>         <property name="resourceLoaderPath" value="WEB-INF/views/" />     </bean>     <!-- Simple ViewResolver for Velocity, appending ".vm" to logical view names -->     <bean id="viewResolver"         class="org.springframework.web.servlet.view.velocity.VelocityViewResolver">         <property name="contentType" value="text/html;charset=gbk" />         <property name="suffix" value=".vm" />     </bean> </beans>

 

5.  补全velocity目录：

在src/main/webapp/WEB-INF下创建views文件夹。

 

 

三、集成ibatis+mysql

 

1.  引入jar包

    打开pom.xml，添加如下依赖：

<!-- ibatis -->      <dependency>   <groupId>org.apache.ibatis</groupId>   <artifactId>ibatis-sqlmap</artifactId>   <version>2.3.4.726</version>     </dependency>                 <dependency>             <groupId>commons-dbcp</groupId>             <artifactId>commons-dbcp</artifactId>             <version>1.2.1</version>         </dependency>                 <!-- mysql -->         <dependency>             <groupId>mysql</groupId>             <artifactId>mysql-connector-java</artifactId>             <version>5.1.14</version>         </dependency>

 

2.  增加数据库配置：

在src/main/resources/META-INF/spring文件夹下新建db文件夹，新增db.xml文件，内容如下：

<?xml version="1.0" encoding="GB2312"?> <!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframework.org/dtd/spring-beans.dtd"> <beans>     <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">         <property name="driverClassName" value="com.mysql.jdbc.Driver"/>         <property name="url" value="jdbc:mysql://localhost:3306/sw"/>         <property name="username" value="root"/>         <property name="password" value="root"/>     </bean>         <bean id="transactionTemplate"         class="org.springframework.transaction.support.TransactionTemplate">         <property name="transactionManager">             <ref local="transactionManager" />         </property>     </bean>       <bean id="transactionManager"         class="org.springframework.jdbc.datasource.DataSourceTransactionManager">         <property name="dataSource" ref="dataSource"/>     </bean>         <bean id="baseDAO"         class="org.springframework.orm.ibatis.support.SqlMapClientDaoSupport"         abstract="true">         <property name="sqlMapClient">             <ref local="sqlMapClient" />         </property>         <property name="dataSource">             <ref local="dataSource" />         </property>     </bean>           <bean id="sqlMapClient" class="org.springframework.orm.ibatis.SqlMapClientFactoryBean">         <property name="configLocation" value="classpath:sqlmap/sqlmap.xml"/>     </bean>     </beans>

 

3.  增加sqlmap配置：

在src/main/resources文件夹下建立sqlmap文件夹，新建sqlmap.xml：

<?xml version="1.0" encoding="GB2312"?> <!DOCTYPE sqlMapConfig PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" "http://www.ibatis.com/dtd/sql-map-config-2.dtd"> <sqlMapConfig>     <settings cacheModelsEnabled="true" enhancementEnabled="false" lazyLoadingEnabled="false" maxRequests="3000" maxSessions="3000" maxTransactions="3000" useStatementNamespaces="false"/>         <sqlMap resource="sqlmap/xxx-sqlmap-mapping.xml"/> </sqlMapConfig>

xxx为具体表名。

 

4.  增加xxx数据库表sqlmap配置，举例：

在src/main/resources/sqlmap文件夹下增加xxx-sqlmap-mapping.xml：

<?xml version="1.0" encoding="GB2312" ?> <!DOCTYPE sqlMap PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN" "http://www.ibatis.com/dtd/sql-map-2.dtd">   <sqlMap>     <resultMap id="user" class="com.sw.app.dal.dataobject.UserDO">         <result property="id" column="ID" javaType="long" jdbcType="INT" nullValue="0"/>         <result property="name" column="NAME" javaType="java.lang.String" jdbcType="VARCHAR"/>     </resultMap>         <insert id="user_insert">         <![CDATA[             insert into user (name) values (#name#)         ]]>         <selectKey resultClass="long" keyProperty="id" >             SELECT @@IDENTITY AS ID         </selectKey>     </insert>         <select id="user_selectyByName" resultMap="user">         <![CDATA[             SELECT id,name FROM user WHERE name=#name#         ]]>     </select>     </sqlMap>

 

5.  增加dao.xml：

在src/main/resources/META-INF/spring/dal文件夹下增加dao.xml，举例:

<?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:osgi="http://www.springframework.org/schema/osgi"     xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd          http://www.springframework.org/schema/osgi http://www.springframework.org/schema/osgi/spring-osgi.xsd"     default-autowire="byName">         <bean id="userDAO" class="com.sw.app.dal.dao.impl.UserDAOImpl" parent="baseDAO"/>     </beans>

 

 

四、配置运行环境

1.  配置pom.xml：

<build>         <finalName>app</finalName>         <plugins>             <!-- Configuring the Jetty Plugin -->             <plugin>                 <groupId>org.mortbay.jetty</groupId>                 <artifactId>maven-jetty-plugin</artifactId>                 <configuration>                     <scanIntervalSeconds>10</scanIntervalSeconds>                 </configuration>             </plugin>                         <!-- Configuring the Mave Eclipse Plugin -->             <plugin>                 <groupId>org.apache.maven.plugins</groupId>                 <artifactId>maven-eclipse-plugin</artifactId>                 <configuration>                     <downloadSources>true</downloadSources>                     <source>1.7</source>                     <target>1.7</target>                 </configuration>             </plugin>               <!-- Configuring the Mave Compiler Plugin -->             <plugin>                 <groupId>org.apache.maven.plugins</groupId>                 <artifactId>maven-compiler-plugin</artifactId>                 <configuration>                     <source>1.7</source>                     <target>1.7</target>                 </configuration>             </plugin>         </plugins>     </build>

 

2.  导入eclipse

在根目录下运行mvn eclipse:eclipse，然后打开eclipse导入。

 

3.  启动

在根目录下运行mvn jetty:run，输入http://localhost:8080/app/***.htm,即可访问页面。
