SSM配置过程
整个项目结构:
缺一不可~
1.在pom.xml添加jar包
这里每个架包的作用是什么我先不做解释,现在只需要将下面的代码全部拷贝进入pom.xml文件就可以。

2.配置web.xml文件
将下面代码全部直接拷入,拷入完会报红,这行先不用管
<?xml version="1.0" encoding="UTF-8" ?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
id="WebApp_ID" version="2.5">
<!--1.启动spring的容器-->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:applicationContext.xml</param-value>
</context-param>
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!--2.spring的前端控制器,用它来拦截前端的所有请求-->
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--3.字符编码过滤器 必须放在所有过滤器之前-->
<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>forceRequestEncoding</param-name>
<param-value>true</param-value>
</init-param>
<init-param>
<param-name>forceResponseEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/</url-pattern>
</filter-mapping>
<filter>
<filter-name>HiddenHttpMethodFilter</filter-name>
<filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>HiddenHttpMethodFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
3.配置Spring
Spring里面需要做的是 连接数据库,控制事物
1.在main目录下面新建resource的资源文件applicationContext.xml文件
2.在resource资源文件新建Spring的配置文件applicationContext.xml
3.插入以下代码
会报红,先不管问题是什么
<?xml version="1.0" encoding="UTF-8"?>

<!--所有都是事物方法-->

<!--以get开始的所有方法-->

</tx:attributes>
</tx:advice>
</beans>
3.1 mybatis-config.xml
在resource资源文件下添加mybatis-config.xml关于数据库的配置信息
插入以下代码
<?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="mapUnderscoreToCamelCase" value="true"/>
</settings>
<typeAliases>
<package name="org.bean"/>
</typeAliases>
<plugins>
<!-- com.github.pagehelper为PageHelper类所在包名 -->
<plugin interceptor="com.github.pagehelper.PageInterceptor">
<property name="reasonable" value="true"/>
</plugin>
</plugins>
</configuration>
3.2 dbconfig.properties
有关数据库连接信息信息
插入以下代码:
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm?characterEncoding=utf-8
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=root
4.SpringMvc配置
插入以下代码
<?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/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">
<!--SpringMVC的配置文件,包含网站跳转逻辑的控制,配置 -->
<context:component-scan base-package="org" use-default-filters="false">
<!--只扫描控制器。 -->
<context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!--配置视图解析器,方便页面返回 -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"></property>
<property name="suffix" value=".jsp"></property>
</bean>
<!--两个标准配置 -->
<!-- 将springmvc不能处理的请求交给tomcat -->
<mvc:default-servlet-handler/>
<!-- 能支持springmvc更高级的一些功能,JSR303校验,快捷的ajax...映射动态请求 -->
<mvc:annotation-driven/>
</beans>
5.代码控制目录
1.在main下新建以下5个文件夹
2.reource下的mapper文件夹:
mapper文件放的数据库反向工程的xml文件
6.反向编译数据库
1.在根目录新建lib目录,放入数据库连接架包:
2.在resources資源文件下新建文件generatorConfig.xml:
插入以下代码:
<?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="D:\ProjectPlace\IdeaPlace\Qimo_Web\lib\mysql-connector-java-5.1.42.jar"/>
<context id="testTables" targetRuntime="MyBatis3">
<commentGenerator>
<property name="suppressAllComments" value="true" />
</commentGenerator>
<!-- 配置数据库连接 -->
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/weixinmall"
userId="root"
password="root">
</jdbcConnection>
<javaTypeResolver>
<property name="forceBigDecimals" value="false" />
</javaTypeResolver>
<!-- 指定javaBean生成的位置 -->
<javaModelGenerator targetPackage="org.bean"
targetProject="D:\ProjectPlace\IdeaPlace\Qimo_Web\src\main\java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
</javaModelGenerator>
<!--指定sql映射文件生成的位置 -->
<sqlMapGenerator targetPackage="mapper" targetProject="D:\ProjectPlace\IdeaPlace\Qimo_Web\src\main\resources">
<property name="enableSubPackages" value="true" />
</sqlMapGenerator>
<!-- 指定dao接口生成的位置,mapper接口 -->
<javaClientGenerator type="XMLMAPPER"
targetPackage="org.dao"
targetProject="D:\ProjectPlace\IdeaPlace\Qimo_Web\src\main\java">
<property name="enableSubPackages" value="true" />
</javaClientGenerator>
<!-- table指定每个表的生成策略 -->
<table tableName="bigclass" domainObjectName="big_class"></table>
<table tableName="cart" domainObjectName="cart_class"></table>
</context>
</generatorConfiguration>
3.添加插件Mybatis插件:
在pom.xml文件添加一下代码:
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.7</version>
</plugin>
4.添加配置,不添加的话这里是没这东西的
添加配置
2.
3.原模原样的填入以下信息:
填写完成后就会在右边看到如下:
这时我们只需双击它就可以反向编译数据:
编译完的目录变化
