Maven配置Spring+SpringMVC+MyBatis(3.2.2)Pom

配置原则：

利用依赖，将所需的jar包载入到工程中。

1. 先依赖主要jar包
   Spring + Spring MVC + MyBatis + database

2. 再依赖次要jar包
   C3p0连接池，log4j，Junit

3. 外围jar包
   POI jFreeCharts jxl

例子：

通常只使用Spring时，将spring-context依赖到pom中。

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

效果图如下：

spring-context会将一下jar，自动依赖过来。

commons-logging:1.1.1
spring-aop:3.2.2.RELEASE
spring-beans:3.2.2.RELEASE
spring-context:3.2.2.RELEASE
spring-core:3.2.2.RELEASE
spring-expression:3.2.2.RELEASE

由于，这个项目使用Spring+SpringMVC+MyBatis作为架构，其核心就SpringMVC。
所以首先依赖spring-webmvc

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

同理，spring-webmvc会将以下jar包自动依赖到工程中。

commons-logging:1.1.1
spring-aop:3.2.2.RELEASE
spring-beans:3.2.2.RELEASE
spring-context:3.2.2.RELEASE
spring-core:3.2.2.RELEASE
spring-expression:3.2.2.RELEASE
spring-web:3.2.2.RELEASE
spring-webmvc:3.2.2.RELEASE

效果图如下：

使用Spring时，缺少不了事务的存在，而事务是在spring-orm中，将spring-orm依赖到项目中

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

同理，spring-orm会将一下jar包，自动依赖到工程中。

下面是Spring + SpringMVC + MyBatis + POI 的所有POM.xml文件信息。

使用Intellij IDEA 查看POM依赖视图：

1. View --> 选中 Tools Buttons
   
2. 点击左侧的Struture视图。
   
3. 在Project右键 --> Diagrams --> Show Dependencies
