       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/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">
</beans>

配置注解扫描（无需扫描controller层）

<context:component-scan base-package="com.boerk">
    <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

配置数据源信息（整合mybatis）

<!--引入外部文件-->
<context:property-placeholder location="classpath:jdbc.properties"/>
<!--配置数据源信息-->
<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>
</bean>

配置sqlSessionFactory（需要spring整合mybatis的依赖）

<!--配置sqlSessionFactory信息-->
<bean id="sessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="configLocation" value="classpath:sqlMapConfig.xml"></property>
</bean>

<!--事务增强-->
<tx:advice id="txAdvice">
    <tx:attributes>
        <tx:method name="*"/>
    </tx:attributes>
</tx:advice>
<!--事务的aop,可以使用注解方式。-->
<aop:config>
    <aop:advisor advice-ref="txAdvice" pointcut="execution(* com.boerk.service.*.*(..))"></aop:advisor>
</aop:config>

配置SpringMVC

表头

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
       http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/mvc
       http://www.springframework.org/schema/mvc/spring-mvc.xsd
       http://www.springframework.org/schema/context
       http://www.springframework.org/schema/context/spring-context.xsd">
</beans>

配置注解扫描（只扫描Controller层）

<context:component-scan base-package="com.boerk.controller"/>

配置注解驱动

<mvc:annotation-driven/>

配置视图解析器（以jsp举例）

<bean id="resourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/pages/"/>
    <property name="suffix" value=".jsp"/>
</bean>

thymeleaf

<!-- 配置Thymeleaf视图解析器 -->
<bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver">
    <property name="order" value="1"/>
    <property name="characterEncoding" value="UTF-8"/>
    <property name="templateEngine">
        <bean class="org.thymeleaf.spring5.SpringTemplateEngine">
            <property name="templateResolver">
                <bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver">
                    <!-- 视图前缀 -->
                    <property name="prefix" value="/WEB-INF/templates/"/>
                    <!-- 视图后缀 -->
                    <property name="suffix" value=".html"/>
                    <property name="templateMode" value="HTML5"/>
                    <property name="characterEncoding" value="UTF-8" />
                </bean>
            </property>
        </bean>
    </property>
</bean>

配置开放对静态资源的访问

<mvc:default-servlet-handler/>

mybatis配置

<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
    <!--定义别名-->
    <typeAliases>
        <package name="com.boerk.pojo"></package>
    </typeAliases>
</configuration>

web.xml配置

表头

<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">
</web-app>

配置contextConfigLocation

<context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
</context-param>

配置监听器

<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

配置前端控制器

<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-mvc.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>

配置过滤器，来处理乱码问题（需配置encoding和forceResponseEncoding）

如果是jsp页面则需要设置@RequestMapping(value = "/save",produces = "text/html;charset=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>
</filter>
<filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>
