eclipse如何搭建springmvc +mybatis

如题所述

推荐答案 2014-02-28

SpringMVC+MyBatis+Freemarker 简单框架搭建（一）

一、开发环境：
Eclipse、Tomcat、SVN等请参见如下的帖子，很详细了。
http://www.iteye.com/topic/982182

svn和maven插件的安装：
1、先安装gef插件
地址：http://download.eclipse.org/tools/gef/updates/interim/
2、安装svn插件
地址：http://subclipse.tigris.org/update_1.6.x
3、maven插件
m2eclipse-core Update 地址： http://m2eclipse.sonatype.org/sites/m2e
m2eclipse-extras Update 地市： http://m2eclipse.sonatype.org/sites/m2e-extras
4、安装可能出现的问题
直接在线安装maven2 会出现依赖插件找不到的问题，无法安装。必须先安装gef 插件后才能安装m2eclipse-core 插件，然而安装m2eclipse-extras 插件又依赖subclipse 插件。所以，三个插件的正确的安装顺序是：gef插件》subclipse插件》m2eclipse插件

二、web.xml 和 applicationContext.xml 配置
1、web.xml文件配置：
<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
version="2.5">

<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>


<servlet>
<servlet-name>springServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:contextConfigLocation-springService.xml</param-value>
</init-param>
<load-on-startup>0</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>springServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>


<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>




<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener>


<session-config>
<session-timeout>20</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>


<filter>
<filter-name>Set Character Encoding</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>GB2312</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>Set Character Encoding</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>


<display-name>Archetype Created Web Application</display-name>
</web-app>

<context-param>节点和<listener>节点是web项目启动时最先读取的两个节点，所以这两个节点里面所配置的内容是web项目启动时最先加载的部分。
<context-param>节点中配置的applicationContext.xml里面主要是数据库的配置信息，以及事务等等
<listener>节点配置的是web请求的监听器

2、applicationContext.xml 内容如下：

<?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:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context"
xmlns:p="http://www.springframework.org/schema/p"
xsi:schemaLocation="
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.1.xsd
">


<context:component-scan base-package="com.weiluo.example">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>




<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<value>classpath:jdbc.properties</value>
</list>
</property>
</bean>


<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="driverClassName" value="${jdbc.driver}"></property>
<property name="url"
value="${jdbc.url}"></property>
<property name="username" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>


<property name="maxActive" value="${dbcp.maxActive}" />
<property name="maxIdle" value="${dbcp.maxIdle}" />
<property name="defaultAutoCommit" value="false" />

<property name="timeBetweenEvictionRunsMillis" value="360000" />
<property name="minEvictableIdleTimeMillis" value="360000" />
</bean>


<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"
p:dataSource-ref = "dataSource"
p:configLocation = "classpath:sqlMapConfig.xml" />


<bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate">
<constructor-arg index="0" ref="sqlSessionFactory" />
</bean>


<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"
p:dataSource-ref = "dataSource" />


<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"
p:basePackage = "com.weiluo.example.entity" />


<tx:annotation-driven/>

</beans>

3、web.xml中的<servlet>节点配置的是与请求处理相关的一些内容，主要是 url路由处理器，视图解析器，等等，如下：

<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"
xmlns:util="http://www.springframework.org/schema/util" xmlns:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="
http://www.springframework.org/schema/util
http://www.springframework.org/schema/util/spring-util-3.1.xsd
http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd">


<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping">
<property name="order" value="1" />
</bean>

<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="jsonHttpMessageConverter" />
</list>
</property>
</bean>
<bean id="jsonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
</bean>



<context:component-scan base-package="com.weiluo.example.controller">
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<mvc:resources location="/static/" mapping="/static/**" />


<bean id="viewResolver"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="cache" value="true" />
<property name="prefix" value="" />
<property name="suffix" value=".html" />
<property name="exposeSpringMacroHelpers" value="true" />
<property name="exposeRequestAttributes" value="true" />
<property name="exposeSessionAttributes" value="true" />
<property name="requestContextAttribute" value="rc" />
<property name="contentType" value="text/html;charset=GB2312" />
<property name="order" value="0"/>
</bean>


<bean id="blockDirective"
class="com.weiluo.example.freemarker.directive.BlockDirective" />
<bean id="extendsDirective"
class="com.weiluo.example.freemarker.directive.ExtendsDirective" />
<bean id="overrideDirective"
class="com.weiluo.example.freemarker.directive.OverrideDirective" />
<bean id="superDirective"
class="com.weiluo.example.freemarker.directive.SuperDirective" />


<bean id="freemarkerConfig"
class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="/WEB-INF/views/" />
<property name="freemarkerSettings">
<props>
<prop key="template_update_delay">5</prop>
<prop key="defaultEncoding">GB2312</prop>
<prop key="datetime_format">yyyy-MM-dd HH:mm:ss</prop>
<prop key="date_format">yyyy-MM-dd</prop>
<prop key="time_format">HH:mm:ss</prop>
<prop key="number_format">0.######</prop>
<prop key="whitespace_stripping">true</prop>
</props>
</property>
<property name="freemarkerVariables">
<map>
<entry key="extends" value-ref="extendsDirective"></entry>
<entry key="override" value-ref="overrideDirective"></entry>
<entry key="block" value-ref="blockDirective"></entry>
<entry key="super" value-ref="superDirective"></entry>
</map>
</property>
</bean>

</beans>

4、另外，一些常常变化的信息习惯于存放在application.properties文件里面，如：

#oracle version database setting
database=sqlserver
#jdbc.driver=oracle.jdbc.driver.OracleDriver
jdbc.driver=net.sourceforge.jtds.jdbc.Driver
#jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:jtds:sqlserver://127.0.0.1:1433;databaseName=SpringMyBatisExample
#jdbc.url=jdbc:mysql://localhost:3306/springmvcdemo
jdbc.username=sa
jdbc.password=sasa

#dbcp settings
dbcp.maxIdle=5
dbcp.maxActive=20

到这里，一个spring mvc的基本框架就已经搭建起来了。
后续再完成数据库mybatis的配置以及freemarker的配置。

    eclipse搭建springmvc +mybatis的步骤如下：

    1、首先创建Web项目；

    2、引入所有的相关jar文件；

    3、配置web.xml；

    web.xml是项目的入口，既然使用spring那么当然要添加Spring的支持啦，spring默认加载的是applicationContext.xml，由于需要集成MyBatis，所以把Spring的配置文件强制指定名称，并与MyBatis一起配置，减少配置文件数量。

    （1）、先指定spring配置文件名名称与路径

<context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:xmlconfig/springmvc-mybatis.xml</param-value>
    </context-param>

    （2）、再执行Spring上下文监听配置
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

（3）、添加支持Spring mvc 的配置


<servlet>
    <servlet-name>springmvc</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:/xmlconfig/springmvc-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
    <servlet-name>springmvc</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

由于采用的是tomcat服务器，为了让静态的资源直接交给tomcat处理，所以在web.xml中配置了以下配置：

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.jpg</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.gif</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.png</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
</servlet-mapping>
<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
</servlet-mapping>

4、配置springmvc-mybatis.xml和springmvc-servlet.xml；

springmvc-mybatis.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans 配置信息>

    
    <bean id="dataSource" class="com.jolbox.bonecp.BoneCPDataSource">
        <property name="driverClass" value="jdbc:mysql://主机加端口号/web" />
        <property name="jdbcUrl" value="root" />
        <property name="username" value="123456" />
        <property name="password" value="com.mysql.jdbc.Driver" />
    </bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" value="classpath*:dbmap/*Mapper.xml" />
    </bean>

    
    <bean id="transactionManager"
          class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <bean id="jdbcTemplate" class="org.springframework.jdbc.core.JdbcTemplate">
        <property name="dataSource">
            <ref bean="dataSource" />
        </property>
    </bean>
    <bean id="defaultLobHandler"
          class="org.springframework.jdbc.support.lob.DefaultLobHandler"
          lazy-init="true"/>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.ansitech.web.orm.mapper" />
    </bean>
</beans>

spring-servlet.xml：

<?xml version="1.0" encoding="UTF-8"?>
<beans 配置信息>

    <description>Spring MVC Configuration</description>

    
    <mvc:default-servlet-handler/>

    
    <context:annotation-config />

    
    <mvc:annotation-driven />

    
    <context:component-scan base-package="com.ansitech.web"></context:component-scan>

    
<bean class=
      "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>

    
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

    <property name="prefix" value="/WEB-INF/view/"/>
    <property name="suffix" value=".jsp"/>
    <property name="viewNames" value="jsp/*"/>
    <property name="order" value="1"/>
</bean>

<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
    <property name="prefix" value="/WEB-INF/view/"/>
    <property name="suffix" value=".jsp"/>
    <property name="order" value="2"/>
</bean>

    
    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        
        <property name="maxUploadSize">
            <value>5242880</value>
        </property>
    </bean>
</beans>

web.xml：
<?xml version="1.0" encoding="UTF-8"?>
<web-app 配置信息>
    
    <session-config>
        
        <session-timeout>30</session-timeout>
    </session-config>

    
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.jpg</url-pattern>
    </servlet-mapping>
    <servlet-mapping>
        <servlet-name>default</servlet-name>
        <url-pattern>*.gif</url-pattern>
    </servlet-mapping>
    <servlet-mapping>

        <url-pattern>*.png</url-pattern>
    </servlet-mapping>
    <servlet-mapping>

    </servlet-mapping>

    
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:xmlconfig/springmvc-mybatis.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:/xmlconfig/springmvc-servlet.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    
    <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>
        <init-param>
            <param-name>forceEncoding</param-name>
            <param-value>true</param-value>
        </init-param>
    </filter>
    <filter-mapping>
        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    
    <welcome-file-list>
        <welcome-file>/index.html</welcome-file>
    </welcome-file-list>
</web-app>

至此，就完成了springmvc +mybatis的搭建了。

一，jar包准备。

下载了Mybatis 和 Spring 的jar包基本上都添加上去了，如图：

二、 web.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

</servlet>

<servlet-mapping>

<servlet-name>web</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<servlet-mapping>

<servlet-name>web</servlet-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

</init-param>

</servlet>

<error-page>

<exception-type>java.lang.Throwable</exception-type>

</error-page>

<error-page>

<error-code>404</error-code>

</web-app>

三、 
<servlet>
  <servlet-name>web</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  
  
  <load-on-startup>1</load-on-startup>
</servlet> 这个我使用的是默认的 web-servlet.xml文件. 如下:

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"
