SSM框架需要的所有类配置类代码

SSM框架的配置主要包括三个部分：Spring配置、MyBatis配置和Web配置。下面是一个简单的SSM框架配置文件示例：

1. Spring配置文件 applicationContext.xml

<!-- 配置扫描包 -->
<context:component-scan base-package="com.example"/>

<!-- 配置数据源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/>
    <property name="url" value="jdbc:mysql://localhost:3306/test"/>
    <property name="username" value="root"/>
    <property name="password" value="123456"/>
</bean>

<!-- 配置MyBatis的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*:com/example/mapper/*.xml"/>
</bean>

<!-- 配置事务管理器 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>

<!-- 开启注解事务 -->
<tx:annotation-driven transaction-manager="transactionManager"/>

2. MyBatis配置文件 mybatis-config.xml

<?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>
    <!--开启驼峰命名法-->
    <settings>
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>
    <!--配置类型别名-->
    <typeAliases>
        <package name="com.example.entity"/>
    </typeAliases>
    <!--配置插件-->
    <plugins>
        <plugin interceptor="com.example.plugin.PaginationPlugin"/>
    </plugins>
</configuration>

3. Web配置文件 web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
    <display-name>SSM-Demo</display-name>

    <!-- 配置DispatcherServlet -->
    <servlet>
        <servlet-name>dispatcher</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>

    <!-- 配置DispatcherServlet映射 -->
    <servlet-mapping>
        <servlet-name>dispatcher</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>
</web-app>

4. SpringMVC配置文件 spring-mvc.xml

<!-- 配置扫描包 -->
<context:component-scan base-package="com.example.controller"/>

<!-- 配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/views/"/>
    <property name="suffix" value=".jsp"/>
</bean>

<!-- 配置静态资源访问 -->
<mvc:default-servlet-handler/>
<mvc:annotation-driven/>
