說明：

1.項目使用ssm+jdk8+Oracle，如果使用mysql，不需要集成odbc

2.這篇不包含業務邏輯，只有框架。

3.有問題，請指出。歡迎留言

4.框架下載地址：https://download.csdn.net/download/qq_27102865/11805526

一、創建一個SSM框架

1. 新建maven項目

2. 選擇webapp

3. 輸入相關信息

二、項目配置

1. Java Build Path

默認可能jre可能是1.5，我用的是1.8。

還要添加Tomcat。修改後

2. Java Compiler

3. Project Facets

修改DWM2.3->2.5,打開項目路徑，在.setting目錄下找到org.eclipse.wst.common.project.facet.core.xml，編輯打開：

編輯爲2.5，保存。

配置完成以後，項目基本是這個樣子

我們maven update一下，就變成了這個樣子。

pom文件，這樣改：https://www.cnblogs.com/fanshuyao/p/8565504.html

添加紅色部分代碼：

<plugins>
	<plugin>
		<groupId>org.apache.maven.plugins</groupId>
		<artifactId>maven-compiler-plugin</artifactId>
		<version>3.1</version>
		<configuration>
			<source>1.8</source>
			<target>1.8</target>
		</configuration>
	</plugin>
</plugins>

添加後再來一次maven update。可以了

三、增加/修改配置文件

1. 繼續修改pom文件

創建一個空的SSM項目

一、創建一個SSM框架

1. 新建maven項目

2. 選擇webapp

3. 輸入相關信息

二、項目配置

1. Java Build Path

2. Java Compiler

3. Project Facets

三、增加/修改配置文件

1. 繼續修改pom文件

2. 修改web.xml

3. /SSM01/src/main/resources/config/applicationContext.xml

4. /SSM01/src/main/resources/config/spring-mvc.xml

5. /SSM01/src/main/resources/datasource/datasource.properties

6. /SSM01/src/main/java/testSSM/project/hello/Controller/HelloController.java

7.添加odbc。

四、啓動

1. http://localhost:8080/SSM01/

2. http://localhost:8080/SSM01/hello/test.html
