创建ssm项目步骤
步骤
理解web应用流程
1、创建一个Javaweb ssm(maven)项目
参考链接
2、导入依赖

<build>

<!--在IDEA中maven 默认编译的时候 只搬运src/main/java里面的java文件到target/classes,其他文件会被忽略 -->
<!--这时，我们Mybatis的Mapper.xml文件就不能被加载进去，也就是不能映射成功 -->

</build>
</project>
3、配置web.xml
-
加载spring容器
-
配置springmvc前端控制器
-
字符编码过滤器
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1"> <display-name>Archetype Created Web Application</display-name> <!--加载spring容器--> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/spring/applicationContext-*.xml</param-value> </context-param> <!--配置springmvc前端控制器--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--contextConfigLocation配置SpringMVC加载的配置文件（配置处理器，映射器等等） 如果不配置contextConfigLocation，默认加载的是：/WEB-INF/servlet名称-servlet.xml(springmvc-servlet.xml) --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--乱码过滤器--> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <welcome-file-list> <welcome-file>login.jsp</welcome-file> </welcome-file-list> </web-app>
4、资源文件
4.1 db.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://locahost:3306/examination
jdbc.username=root
jdbc.password=0000
4.2 applicationContext-dao.xml
- 加载外部配置文件
- 配置数据源
- 配置SqlSessionFactory
- Mapper批量扫描
<?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"

<!--加载数据库配置文件-->
<context:property-placeholder location="classpath:db.properties"></context:property-placeholder>
<!--配置数据源 c3p0l连接池-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value="${jdbc.driver}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>

<!--配置SqlSessionFactory-->
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!--加载mybatis配置文件-->
<property name="configLocation" value="classpath:mybatis/mybatis.cfg.xml"></property>
<!--加载数据源-->
<property name="dataSource" ref="dataSource"></property>
</bean>
<!--Mapper批量扫描，从Mapper包扫描接口，自动创建代理对象，并在Spring容器中自动注册
使用 Mybatis与Spring整合包的这个 Mapper 扫描器后， Mybatis 配置文件里的扫描器，就可以取消掉了
遵循的规范 不变
自动扫描出来的Mapper的bean的id为Mapper类名（首字母小写）
-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<!--如果需要扫描多个包下的mapper,每个包中间使用半角逗号分开-->
<property name="basePackage" value="com.system.mapper"></property>
<property name="sqlSessionFactoryBeanName" value="sessionFactory"></property>
</bean>
</beans>
4.3 springmvc.xml
- 加载静态资源
- 开启注解扫描
- 组件扫描
- 视图解析器
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
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/aop
http://www.springframework.org/schema/aop/spring-aop.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
<!--静态资源解析包括 ：js、css、img、.. -->
<!-- <mvc:resources mapping="/js/" location="/js/**" />
<mvc:resources mapping="/css/" location="/css/**" />
<mvc:resources mapping="/fonts/" location="/fonts/**" />
<mvc:resources mapping="/images/" location="/images/**"/> -->
<!--加载静态资源 -->
<mvc:default-servlet-handler />
<!--<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<开启注解方式：配置>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> -->
<!--使用annotation-driven 注解驱动，就可以代替 注解映射器 和 注解适配器 的配置 -->
<!--conversion-service 向处理器适配器中注入【自定义的参数绑定组件】。 -->
<!--validator 向处理器适配器，注入 校验器 -->
<mvc:annotation-driven conversion-service="conversionService">
</mvc:annotation-driven>
<!--自定义参数绑定组件 -->
<!-- <bean id="conversionService"
class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
<!– 转换器 –>
<property name="converters">
<set>
<!– 日期类型转换 –>
<bean class="com.system.controller.converter.CustomDateConverter" />
</set>
</property>
</bean>-->
<!--组件扫描，可以扫描 controller、Service、... 并注册添加到 spring 容器中 这里扫描 controller，指定controller的包 -->
<context:component-scan base-package="com.system.controller" />
<!--全局错误信息处理器 只要实现HandlerExceptionResolver接口就是全局异常处理器 -->
<!-- <bean class="com.system.exception.CustomExceptionResolver" />-->
<!--视图解析器 -->
<!-- 需要配置解析jsp的视图解析器 jsp解析，默认使用jstl标签解析 -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--拼接视图地址的前缀和后缀 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
