一、创建Maven项目 略 ## 二、配置web.xml文件 ```xml <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1"> <display-name>ssm</display-name> <!-- 过滤器解决中文乱码问题、强制编码 UTF-8 --> <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> </filter> <filter-mapping> <filter-name>characterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 配置 springMVC 基本配置 --> <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:spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springMVC</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 配置 spring 监听器 --> <!-- needed for ContextLoaderListener --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- Bootstraps the root web application context before servlet initialization --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 配置欢迎页 --> <welcome-file-list> <welcome-file>views/index.jsp</welcome-file> </welcome-file-list> </web-app> ``` ## 四、在src/main/resources下创建spring配置文件 ##### 创建applicationContext.xml配置如下 ```xml <?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:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" 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-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd"> <!-- 自动扫描指定目录，将控制器加载到bean --> <context:component-scan base-package="com.frame" /> <!-- 配置 druid 数据源 --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- 基本属性 url、user、password、driverClass --> <property name="username" value="root" /> <property name="password" value="root" /> <property name="driverClassName" value="com.mysql.jdbc.Driver" /> <property name="url" value="jdbc:mysql://192.168.0.200:3306/test?useUnicode=true&amp;characterEncoding=utf8&amp;useSSL=false" /> </bean> <!-- 配置 sessionFactory --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations"> <list> <value>classpath:com/frame/**/*Mapper.xml</value> <value>classpath:mybatis/**/*Mapper.xml</value> </list> </property> </bean> <!-- 配置 sqlSessionTemplate 持久化模板 --> <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg ref="sqlSessionFactory" /> </bean> <!-- 配置事物管理器 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 配置事物传播行为 --> <tx:advice id="txAdvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="get*" read-only="true" /> <tx:method name="find*" read-only="true" /> <tx:method name="select*" read-only="true" /> <tx:method name="*" propagation="REQUIRED" /> </tx:attributes> </tx:advice> <!-- 配置事物切入点 --> <aop:config> <aop:pointcut expression="execution(* com.frame.service.*.*(..))" id="pointCut" /> <aop:advisor advice-ref="txAdvice" pointcut-ref="pointCut" /> </aop:config> <!-- 开始声明式事务（事物注解） --> <tx:annotation-driven transaction-manager="transactionManager" /> </beans> ``` ##### 创建spring-mvc.xml配置如下 ```xml <?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" 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-4.3.xsd"> <!-- 自动将控制器加载到bean --> <context:component-scan base-package="com.frame.controller" /> <!-- 配置视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/views/" /> <property name="suffix" value=".jsp" /> <!-- 可为空,方便实现自已的依据扩展名来选择视图解释类的逻辑 --> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" /> </bean> <!-- 返回json 需导入 jackson-annotations.jar，jackson-core.jar，jackson-databind.jar --> <!-- 通过处理器映射DefaultAnnotationHandlerMapping来开启支持@Controller注解 --> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerMapping" /> <!-- 通过处理器适配器AnnotationMethodHandlerAdapter来开启支持@RequestMapping注解 --> <bean class="org.springframework.web.servlet.mvc.method.annotation.RequestMappingHandlerAdapter"> <property name="messageConverters"> <list> <!-- 配置返回字符串编码 --> <bean class="org.springframework.http.converter.StringHttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>text/html; ch
