Spring + Spring mvc + Ibatis + Velocity 框架搭建

bruce128 分享于 2016-06-21

推荐:velocity+struts+spring+ibatis

企业web应用采用框架struts(webwork)+spring+ibatis(hibernate)其实大可以做到,web页面我个人认为使用velocity模板替换JSP或者配合JSP使用,效果会非常好,如

    总结下如何用这四个常用框架搭建一个Java Web工程,方便以后更快速的开发工程。首先得用maven搭建一个多模块的web工程,这里不再赘述,请参考以前的总结:用maven命令行创建多模块WEB项目

    首先导入这些框架所需的maven依赖:

<spring.version>3.2.2.RELEASE</spring.version>
<v.velocity>1.6.3</v.velocity>
<v.velocity.tool>1.2</v.velocity.tool>
<jdbc.driver.version>5.1.15</jdbc.driver.version>

<!-- ibatis begin -->
<dependency>
    <groupId>org.apache.ibatis</groupId>
    <artifactId>ibatis-sqlmap</artifactId>
    <version>2.3.4.726</version>
</dependency>

<dependency>
    <groupId>mysql</groupId>
    <artifactId>mysql-connector-java</artifactId>
    <version>${jdbc.driver.version}</version>
</dependency>
<!-- ibatis end -->

<!-- spring begin -->
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-orm</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-jdbc</artifactId>
    <version>${spring.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-core</artifactId>
    <version>${spring.version}</version>
</dependency>
<dependency>
    <artifactId>spring-context</artifactId>
    <groupId>org.springframework</groupId>
    <version>${spring.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-web</artifactId>
    <version>${spring.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${spring.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-context-support</artifactId>
    <version>${spring.version}</version>
</dependency>

<dependency>
    <groupId>org.springframework</groupId>
    <artifactId>spring-webmvc</artifactId>
    <version>${spring.version}</version>
</dependency>
<!-- spring end -->

<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

<dependency>
    <groupId>javax.servlet.jsp</groupId>
    <artifactId>jsp-api</artifactId>
    <version>2.1</version>
    <scope>provided</scope>
</dependency>

<!-- velocity begin -->
<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity</artifactId>
    <version>${v.velocity}</version>
</dependency>
<dependency>
    <groupId>velocity-tools</groupId>
    <artifactId>velocity-tools</artifactId>
    <version>${v.velocity.tool}</version>
</dependency>
<!-- velocity end -->

    web.xml里配置spring和spring mvc 入口

	<servlet>
		<servlet-name>appServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:spring-config.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<servlet-mapping>
		<servlet-name>appServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>

    DispatcherServlet是spring mvc的所有请求入口的servlet。contextConfigLocation参数配置spring的总配置文件位置。如果是spring集成struts的话,还需要单独配置spring的监听器,但是如果是集成spring mvc,则不需要下面这段配置了:

<listener>
	<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<context-param>
	<param-name>contextConfigLocation</param-name>
	<param-value>classpath:spring-context.xml</param-value>
</context-param>

    spring总配置文件

推荐:spring mvc 框架搭建及详解

  现在主流的Web MVC框架除了Struts这个主力 外,其次就是Spring MVC了,因此这也是作为一名程序员需要掌握的主流框架,框架选择多了,应对多变的需求和业务时

    <mvc:annotation-driven/>

    <bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:im-king.properties</value>

        </property>
    </bean>

    <import resource="spring/spring-config-mvc.xml"></import>
    <import resource="spring/spring-config-datasource.xml"/>
</beans>

    总配置文件里集成了spring mvc配置文件和ibatis数据源的配置文件。

    viewResolver和velocityConfig节点指定了spring mv返回页面用velocity。

    Ibatis的查询依赖SqlMapClientFactoryBean这个对象的配置。这个对象同时指定了ibatis的总配置文件和数据源。一共配了两个,一个负责读,一个负责写。

    Ibatis总配置文件

<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE sqlMapConfig  PUBLIC "-//iBATIS.com//DTD SQL Map
Config 2.0/" "http://www.ibatis.com/dtd/sql-map-config-2.dtd">

<sqlMapConfig>
    <settings
            cacheModelsEnabled="true"
            enhancementEnabled="true"
            lazyLoadingEnabled="false"
            errorTracingEnabled="true"
            maxRequests="32"
            maxSessions="10"
            maxTransactions="5"
            useStatementNamespaces="true"/>

    <sqlMap resource="sqlmap/word.xml"/>
    
</sqlMapConfig>


    sqlMap节点负责导入分配置文件,也就是sql文件。可以有多个。

    ibatis的sql分配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE sqlMap PUBLIC "-//ibatis.apache.org//DTD SQL Map 2.0//EN" "http://ibatis.apache.org/dtd/sql-map-2.dtd">
<sqlMap namespace="word">
	
	<typeAlias alias="Word" type="com.**.im.RiskKeyWord"/>
	
    <insert id="add" parameterClass="Word">
        INSERT 
        INTO key_word(lib_id, word)
        VALUES (#lib_id#, #word:VARCHAR#)
        <selectKey resultClass="int" keyProperty="id">
            select last_insert_id() limit 1
        </selectKey>
    </insert>
	
	<update id="update" parameterClass="Word">
		UPDATE key_word
		SET lib_id = #lib_id#, word = #word:VARCHAR#
		WHERE id = #id#
	</update>
	
	<select id="query" parameterClass="int" resultClass="Word">
		SELECT id, lib_id, word
		FROM key_word
		WHERE  id = #id#
	</select>
	
	<delete id="del" parameterClass="int" >
		DELETE 
		FROM key_word
		WHERE  id = #id#
	</delete>
</sqlMap>

    ibatis的分配置文件里都是sql语句。
    至此,这四个框架的搭建完成。

推荐:maven搭建spring mvc+ibatis项目

.背景介绍   对于初学者,用maven构建项目并不是一件容易的事,springmvc并不是MVC中的主流,但是本人觉得springmvc比struts要好用,真正做到了零配置。一次使

    总结下如何用这四个常用框架搭建一个Java Web工程,方便以后更快速的开发工程。首先得用maven搭建一个多模块的web工程,这里不再赘述,请参考以前的总结:用maven命令行创建多模块WEB项目
