使用maven搭建环境ssm+oracle简单项目

2.Eclipse下创建Maven项目

这里创建一个Maven project，上面的Maven Module是maven模块化开发用到的，可以理解为子工程。

接着Next

这里选择maven-archetype-webapp，创建一个maven-webapp样例工程的意思。

此处groupid和artifactId被统称为“坐标”是为了保证项目唯一性而提出的.。org一般指一些组织机构，非盈利组织。我个人的项目一般喜欢用org。zch是我名字的缩写。artifactId写项目名称就可以了。

工程创建完毕，这就是项目的结构，此处有个错误是因缺少javax.servlet-api依赖导致的。pom文件引入下列内容即可。

<dependency>
<groupId>javax.servlet</groupId>
<artifactId>javax.servlet-api</artifactId>
<version>3.1.0</version>
</dependency>

现在需要改一下项目的结构。因为maven项目是需要下列Source Folder文件夹的。

src/main/resources

src/main/java

src/test/resources

src/test/java

这里提示没有找到这几个文件夹。先把它们remove掉。手动创建

OK，这就是maven项目的结构了，现在已经没有报错提示。提醒：此处创建的是Source Folder文件夹。不要创建成Folder。

下面再改一下输出目录，把下面的allow output folders for source folders勾上。

按上述步骤把那四个source folder改下输出目录。编译的class就是输出到对应的目录下。

src/main/resources和src/main/java选择classes

src/test/resources和src/test/java选择test-classes

到此maven项目的一些基本结构已经建立完毕。下面开始搭建SSM框架开发环境。

提示：一些maven，jdk，tomcat记得要引入配置好。这里我就不说了。

//以下可以直接使用打的jar，因为整合的是oracle注意要引入oracle所需要的jar包，这里maven不提供oracle包需要自己下载。

3.ssm框架整合

首先引入pom依赖的jar包。会自动联网下载相关依赖

读入数据库连接相关参数，配置数据连接池，以及sqlSessionFactory

可以看到数据库的一些连接信息是从其他文件取值的。所以现在需要一个jdbc.properties配置数据库地址等信息。

这里我就打个码了。也提醒各位分享技术贴图贴代码的同时，不要暴露自己的一些隐私信息。

因为我的数据库是装在阿里云上面的。所以我写的是我服务器的地址。如果是本地的话localhost就行了。

mapper映射

resources下新建一个mapper文件夹。用以存放跟Dao类相映射的XML文件

resources下新建一个mybatis-config.xml：

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration
PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
<settings>

<setting name="lazyLoadingEnabled" value="false" />

<setting name="jdbcTypeForNull" value="NULL" />
</settings>
<typeAliases>
<typeAlias alias="User" type="org.portal.entity.User" />
</typeAliases>

<mappers>
<mapper resource="mapper/UserDao.xml"/>
</mappers>
</configuration>

让实体bean映射xml

applicationContext-service.xml

此处目前整合阶段暂时没有多少东西。就一个扫描service包

applicationContext-trans.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

</aop:config>
</beans>

这是配置spring对事务的处理

springmvc.xml

这是配置springmvc。prefix是你的页面文件夹

suffix是后缀名。

web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="3.0"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<param-value>classpath:spring/applicationContext-*.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<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>

</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>

<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring/springmvc.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>

</web-app>

这是一个初始化方法，访问项目可以直接到首页，虽然web.xml也可以配置，但我更倾向于这样写。因为可以在这方法里做一些初始化加载数据等操作。

现在开始测试
