以下是 SSM框架（Spring + Spring MVC + MyBatis）整合配置的详细步骤，适用于 Maven 项目。
（一）、pom.xml中添加相关依赖
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"

<artifactId>javax.servlet-api</artifactId>
<version>4.0.1</version>
</dependency>
</dependencies>
</project>
（二）、配置web.xml
<?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DispatcherServlet-->
<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:applicationContext.xml</param-value>
</init-param>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
<!--解决中文乱码-->
<filter>
<filter-name>characterFilter</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>characterFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
</web-app>
（三）、配置applicationContext.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:mvc="http://www.springframework.org/schema/mvc"
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/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
">
<!--开启SpringMVC注解模式-->
<context:component-scan base-package="com.hirain"/>
<mvc:annotation-driven>
<!--解决响应中文乱码问题-->
<mvc:message-converters>
<bean class="org.springframework.http.converter.StringHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=utf-8</value>
<!--Json序列化输出配置-->
<value>application/json;charset=utf-8</value>
</list>
</property>
</bean>
</mvc:message-converters>
</mvc:annotation-driven>
<mvc:default-servlet-handler/>
<!--配置FreeMarker模板引擎-->
<bean id="freemarkerConfig" class="org.springframework.web.servlet.view.freemarker.FreeMarkerConfigurer">
<property name="templateLoaderPath" value="/WEB-INF/ftl"/>
<property name="freemarkerSettings">
<props>
<prop key="defaultEncoding">UTF-8</prop>
</props>
</property>
</bean>
<bean id="ViewResolver" class="org.springframework.web.servlet.view.freemarker.FreeMarkerViewResolver">
<property name="contentType" value="text/html;charset=utf-8"/>
<property name="suffix" value=".ftl"/>
</bean>
<!--Mybatis与Spring的整合配置-->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
<property name="driverClassName" value="com.mysql.cj.jdbc.Driver"/>
<property name="url"
value="jdbc:mysql://localhost:3306/hirain_reader?useUnicode=true&charactorEncoding=UTF-8&useSSL=false&serverTimezone=Asia/Shanghai"/>
<property name="username" value="root"/>
<property name="password" value="root"/>
<property name="initialSize" value="10"/>
<property name="maxActive" value="20"/>
</bean>
<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"/>
<property name="mapperLocations" value="classpath:mappers/*.xml"/>
<property name="configLocation" value="classpath:mybatis-config.xml"/>
</bean>
<!--配置Mapper扫描器-->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.hirain.reader.mapper"/>
</bean>
</beans>
（四）、 mybatis-config.xml（MyBatis全局配置）
<?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>
<settings>
<!-- 开启驼峰命名转换 -->
<setting name="mapUnderscoreToCamelCase" value="true"/>
</settings>
</configuration>
（五）、项目结构
src/main/java
├── com.hirain.reader.controller # Controller层
├── com.hirain.reader.service # Service层（接口+实现类）
├── com.hirain.reader.dao # DAO层（MyBatis Mapper接口）
├── com.hirain.reader.mapper # mapper接口
src/main/resources
├── mybatis-config.xml # MyBatis全局配置（可选）
├── mappers/*.xml # MyBatis SQL映射文件
├── applicationContext.xml # Spring核心配置
├──db.properties # 数据库连接配置
webapp
├── WEB-INF
│ └── web.xml # Web部署描述文件
│ └──ftl # ftl模板文件夹
│ │ └──test.ftl #测试文件
└── static # 静态资源（CSS/JS/图片）
（六）、测试Mybatis整合是否成功
1、在mapper包下创建TestMapper接口
package com.hirain.reader.mapper;
public interface TestMapper {
public void insert();
}
2、创建TestService
package com.hirain.reader.service;
import com.hirain.reader.mapper.TestMapper;
import org.springframework.stereotype.Service;
import javax.annotation.Resource;
@Service
public class TestService {
@Resource
private TestMapper testMapper;
public void batchInsert(){
for (int i = 0; i < 10; i++) {
testMapper.insert();
}
System.out.println("数据导入成功！");
}
}
3、resources\mappers下创建TestMapper.xml
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.hirain.reader.mapper.TestMapper">
<insert id="insert">
INSERT INTO test (content) VALUES ('sn123456')
</insert>
</mapper>
4、为TestService 生成测试类并运行
package com.hirain.reader.service;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import javax.annotation.Resource;
import static org.junit.Assert.*;
@RunWith(SpringJUnit4ClassRunner.class) // 使用 Spring 的测试运行器
@ContextConfiguration(locations = {"classpath:applicationContext.xml"}) // 加载 Spring 配置文件
public class TestServiceTest {
@Resource
private TestService testService;
@Test
public void batchInsert() {
testService.batchInsert();
}
}
(七)、测试freemarker是否整合成功
1、test.ftl代码如下：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
测试页面
</body>
</html>
2、创建TestController
package com.hirain.reader.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.servlet.ModelAndView;
import java.util.HashMap;
import java.util.Map;
@Controller
@RequestMapping("/test")
public class TestController {
@GetMapping("/t1")
public ModelAndView test1(){
return new ModelAndView("test");
}
@GetMapping("/t2")
@ResponseBody
public Map test2(){
Map result=new HashMap<String,String>();
result.put("message", "成功");
return result;
}
}
3、启动tomcat，浏览器中分别输入“http://localhost:8080/test/t1”和“http://localhost:8080/test/t2”进行测试
