使用maven管理的SSM框架的web工程相关配置

配置pom.xml配置文件，导入依赖

<!--spring+springMVC--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.2.8.RELEASE</version> </dependency> <!--jackson--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.11.2</version> </dependency> <!--连接池 阿里 德鲁伊--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.2.0</version> </dependency> <!--mysql--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.20</version> </dependency> <!--myBatis--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.5.5</version> </dependency> <!--mybatisSpring--> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>2.0.4</version> </dependency> <!--spring-jdbc--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.2.8.RELEASE</version> </dependency>

配置applicationContex.xml文件

<!--配置包扫描--> <context:component-scan base-package="com.xxx"/> <!--配置数据源--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/> <property name="url" value="jdbc:mysql:///database?useUnicode=true&amp;characterEncoding=utf-8&amp;serverTimezone=Asia/Shanghai"/> <property name="username" value="root"/> <property name="password" value="123456"/> </bean> <!--整合MyBatis--> <!--配置sqlSessionFactory--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource"/> <property name="configLocation" value="classpath:MyBatis-Config.xml"/> <property name="mapperLocations" value="classpath:/mappers/*.xml"/> </bean> <!--MyBatis Mapper扫描器--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.xxx.mapper"/> </bean> <!--声明事务处理--> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!--开启注解方式事务管理--> <tx:annotation-driven/>

配置MyBatis-Config.xml配置文件

<settings> <!--开启驼峰命名转换--> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings>

配置Mapper.xml映射文件

<!--namespace填写的是Mapper接口的全类名--> <mapper namespace="com.xxx.mapper.UserMapper"> <!--示例查询语句--> <select id="selectUsernameById" resultType="String"> select username from t_user where id =#{id} </select> </mapper>

配置springmvc.xml配置文件

<!--开启包扫描--> <context:component-scan base-package="com.lly.controller"></context:component-scan> <!--开启注解方式MVC--> <mvc:annotation-driven/> <!--根据配置让请求绕开dispatcherServlet，直接访问静态资源--> <mvc:resources mapping="/**" location="/"/>

配置web.xml配置文件

我的idea中maven自动生成的web.xml配置文件的文件头是有问题的，所以这个文件头也一起贴上。

<?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_4_0.xsd" version="4.0"> <!--配置监听器，用于创建和销毁spring容器--> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/applicationContext.xml</param-value> </context-param> <!--乱码过滤器--> <filter> <filter-name>encodingFilter</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>encodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!--前端控制器的配置--> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:/springmvc.xml</param-value> </init-param> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/*</url-pattern> </servlet-mapping> </web-app>
