maven项目如何快速spring+springmvc+mybatis

     如何快速搭建一个 spring+springmvc+mybatis的项目，按照如下步骤一步步来，即可完成。

  1，配置web.xml文件

  <!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >


<web-app>
  <display-name>everyDayCost</display-name>
  
  <!-- spring监听器 -->
  <context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath*:META-INF/spring/applicationContext.xml
</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
  
  <!-- UTF-8编码 -->
<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>

<!-- DispatcherServlet, Spring MVC的核心 -->
<servlet>
<servlet-name>mvc-dispatcher</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>mvc-dispatcher</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
  
  <!-- ==========Welcome file list ============= -->
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<error-page>
<error-code>401</error-code>
<location>/unauthorized.jsp</location>
</error-page>
<error-page>
<error-code>404</error-code>
<location>/404.jsp</location>
</error-page>
</web-app>

2，配置pom文件，下载需要的jar包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

  </properties>
  
  
</project>

3，创建spring的配置文件applicationContext.xml文件

<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:util="http://www.springframework.org/schema/util" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
    http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd">


<!-- 启用spring mvc 注解处理器 -->
<context:annotation-config></context:annotation-config>
<!-- 设置扫描类 -->
<context:component-scan base-package="com.vz"></context:component-scan>


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


<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
<property name="driverClassName" value="com.mysql.jdbc.Driver" />
<property name="connectionProperties"><value>useUnicode=true;characterEncoding=utf-8</value></property>
<!-- 基本属性 url、user、password -->
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.user}" />
<property name="password" value="${jdbc.password}" />


<!-- 配置初始化大小、最小、最大 -->
<property name="initialSize" value="1" />
<property name="minIdle" value="1" />
<property name="maxActive" value="20" />


<!-- 配置获取连接等待超时的时间 -->
<property name="maxWait" value="60000" />


<!-- 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 -->
<property name="timeBetweenEvictionRunsMillis" value="60000" />


<!-- 配置一个连接在池中最小生存的时间，单位是毫秒 -->
<property name="minEvictableIdleTimeMillis" value="300000" />


<property name="validationQuery" value="SELECT 'x'" />
<property name="testWhileIdle" value="true" />
<property name="testOnBorrow" value="false" />
<property name="testOnReturn" value="false" />


<!-- 打开PSCache，并且指定每个连接上PSCache的大小 -->
<property name="poolPreparedStatements" value="true" />
<property name="maxPoolPreparedStatementPerConnectionSize" value="20" />


</bean>

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自动扫描entity目录, 省掉Configuration.xml里的手工配置 -->
        <property name="typeAliasesPackage" value="com.vz.model" />
        <!-- 显式指定Mapper文件位置 -->
        <property name="mapperLocations" value="classpath*:com/vz/dao/mapper/*.xml" />
        <!-- MyBatis分页插件配置 -->
        <property name="plugins">
            <array>
                <bean class="com.github.pagehelper.PageHelper">
                    <property name="properties">
                        <value>
                            dialect=mysql
                        </value>
                    </property>
                </bean>
            </array>
        </property>
    </bean>
    <!-- 扫描basePackage下所有以@MyBatisRepository标识的 接口-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.vz.dao" />
        <property name="annotationClass" value="com.vz.dao.MyBatisRepository"/>
    </bean>
    
</beans>

4，创建mvc-context配置文件，配置springmvc相关的东西

<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation="http://www.springframework.org/schema/beans
      http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
      http://www.springframework.org/schema/aop
      http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
      http://www.springframework.org/schema/mvc
      http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
      http://www.springframework.org/schema/context
      http://www.springframework.org/schema/context/spring-context-4.2.xsd">


<!-- 启用spring mvc 注解 -->
<context:annotation-config />


<!-- 设置使用注解的类所在的jar包 -->
<context:component-scan base-package="com.vz.controller"></context:component-scan>

    <!-- 以下 validator在使用 mvc:annotation-driven 会 自动注册-->  
  <!--   <bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean">  
        <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
        如果不加默认到 使用classpath下的 ValidationMessages.properties  
        <property name="validationMessageSource" ref="messageSource"/>
    </bean>
    指定自己定义的validator  
    <mvc:annotation-driven validator="validator"/> -->
    <!-- 国际化配置结束 -->


<mvc:resources location="/resources/" mapping="/resources/**" cache-period="3600" />


    <!-- 取消循环引用 -->
    <bean id="JsonConverter" class="com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter">
        <property name="supportedMediaTypes" value="application/json;charset=UTF-8" />
        <property name="features">
            <array value-type="com.alibaba.fastjson.serializer.SerializerFeature">
                <value>DisableCircularReferenceDetect</value>
            </array>
        </property>
    </bean>
    <mvc:annotation-driven>
        <mvc:message-converters>
            <ref bean="JsonConverter"/>
        </mvc:message-converters>
    </mvc:annotation-driven>
    
<bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping"></bean>


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


<!-- 对转向页面的路径解析。prefix：前缀， suffix：后缀 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>


    <!-- 文件上传下载 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<property name="maxUploadSize" value="104857600" />
<property name="maxInMemorySize" value="4096" />
<property name="defaultEncoding"> 
        <value>UTF-8</value> 
    </property>
</bean>

</beans>

5，除此之外，还有提到的jdbc.properties,generatorConfig.xml文件

jdbc.propeties     ::

jdbc.url=jdbc:mysql://127.0.0.1:3306/cost
jdbc.user=root
jdbc.password=123456

generatorConfig.xml  ::

<?xml version="1.0" encoding="UTF-8"?> 
<!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" 
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <classPathEntry 
      location="C:\Users\dhwang\.m2\repository\mysql\mysql-connector-java\5.1.26\mysql-connector-java-5.1.26.jar" />
    <context id="MysqlTables" targetRuntime="MyBatis3">
        <commentGenerator>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true" />
        </commentGenerator>
        <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://127.0.0.1:3306/cost" userId="root"
            password="123456">
        </jdbcConnection>
        <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer true，把JDBC DECIMAL 和 
            NUMERIC 类型解析为java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- targetProject:自动生成代码的位置 -->  
        <javaModelGenerator targetPackage="com.vz.model"
            targetProject="src\main\java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->    
            <property name="enableSubPackages" value="true" />
            <!-- 从数据库返回的值被清理前后的空格  -->   
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <sqlMapGenerator targetPackage="com.vz.dao.mapper"
            targetProject="src\main\java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.vz.dao" targetProject="src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!-- tableName:用于自动生成代码的数据库表；domainObjectName:对应于数据库表的javaBean类名 -->  
        <table schema="dispatch" tableName="ts_everyday_cost" domainObjectName="EveryDayCost"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
            <property name="useActualColumnNames" value="true" />
        </table>
        <!-- <table schema="dispatch" tableName="employee" domainObjectName="Employee"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false">
            <property name="useActualColumnNames" value="true" />
        </table> -->
    </context>
</generatorConfiguration>
