一篇文章學會Spring+SpringMVC+Mybatis+Maven搭建和部署,記一次Spring+SpringMVC+Mybatis+Maven的整合

之前一直沒有用過maven和Mybatis最近自己搭建一個基於Maven的Spring+SpringMVC+Mybatis開發環境。

注:有的時候沒有自己動手真正搭過環境(脫離教學的方式),可能有些地方的問題注意不到的。

會在介紹搭建的同時記錄一些遇見的坑和一些知識點。

首先放上Maven配置檔案。

1、POM.xml(至於maven裡面支援的一些服務外掛什麼的可以自己另行百度)

        注:

                ①、pom檔案要放到專案根目錄下

                ②、maven的檔案結構

                        src/main/java   該source floder用來存放java程式碼

                        src/test/java     該source floder用來存放測試程式碼

                        src/main/webapp     該source floder用來存放jsp和web配置檔案,相當於web專案的webroot

                        target    用來存放maven打包編譯的檔案

        注:普通專案如何改為maven專案

                ①、將專案更改為maven結構

                ②、然後在該專案下執行mvn命令:mvn eclipse:eclipse  專案根目錄必須有pom.xml否則maven無法生成相應目錄結構


 ③、執行成功後在.project中相應位置新增如下配置

    <buildCommand>
      <name>org.eclipse.m2e.core.maven2Builder</name>
    </buildCommand>

    <nature>org.eclipse.m2e.core.maven2Nature</nature>

                ④、在專案的properties選項中,找到Deployment Assembly選項更改專案釋出時的路徑(看是否如下圖,如果上面一切順利,一般不用手動修改)

                

至此,你的專案就轉化為了maven專案了。

maven所需要的jar包可以在 這裡 進行搜尋,還能看到其依賴包

Spring+SpringMVC的配置:

注:寫在前面的話

    一、在配置web.xml的時候尋找spring相關的配置檔案:

           1、沒有手動指定(contextConfigLocation)路徑的話,則預設去web-info下去找(spring預設找applicationContext.xml,springmvc預設找XXX-servlet.xml)。

                    2、如果我們把配置檔案放到src下面,或者自定義包路徑下的時候,可以使用classpath方式尋找。(classpath:後跟配置檔案所在包的路徑,可以使用萬用字元)

                    3、classpath會在當前專案去找,而classpath* 則會連所引用的包中也搜尋

                    4、具體配置介紹請移步這裡:點選開啟連結

①、Web.xml

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

③、SpringMVC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:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="
	    http://www.springframework.org/schema/beans
	    http://www.springframework.org/schema/beans/spring-beans.xsd
	    http://www.springframework.org/schema/context
	    http://www.springframework.org/schema/context/spring-context.xsd
	    http://www.springframework.org/schema/mvc
	    http://www.springframework.org/schema/mvc/spring-mvc.xsd">  

    <!-- 預設的註解對映的支援,自動註冊DefaultAnnotationHandlerMapping和AnnotationMethodHandlerAdapter -->  
    <mvc:annotation-driven />
    <!-- 自動掃描的包名 -->  
    <context:component-scan base-package="com.scarecrow.elearning.uac.controller">
    	<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Service"/>
    </context:component-scan>

    <!-- 檢視解釋類 -->  
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">  
        <property name="prefix" value="/WEB-INF/jsp/"/>  
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

Mybatis的注意:

    因為Mybatis的配置(包括mapper代理生成,mapper掃描等操作)交給了Spring進行管理()

SqlSessionFactoryBean--------->用來掃描mapper.xml檔案的,以及對entity生成別名,以供mapper sql檔案使用。
MapperScannerConfigurer-------->用來掃描mapper介面,並給其注入sqlsession

mybatisMapper配置:

注:mybatis的mapper.xml和對應的介面可以不放在同一個包目錄下,在spring對其進行掃描的時候會根據 namespace 指定的介面去生成例項代理物件。所以,namespace,在這裡不止是為了sql的隔離作用,更重要的是和對應介面關聯起來。

<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.scarecrow.elearning.uac.dao.UserMapper">

	<select id="getUserById" parameterType="int" resultType="User">
		select * from user where id = #{id}
	</select>
	
</mapper>

其他:因為在用mysql6.0+的開發包的時候出現了server time zone 錯誤,設定serverTimeZone一直亂碼無法解決所以換成了5的開發包。mysql用的是5.7的,需要指定ssl為false,不過不指定也不影響開發。

jdbc.url=jdbc:mysql://localhost:3306/elearning?useUnicode=true&characterEncoding=UTF-8&serverTimeZone=GMT&useSSL=false

最後:附上一個簡陋的例子點選開啟連結
