SSM框架整合springmvc代码

好的，下面是一个简单的SSM框架整合SpringMVC的代码示例。这个示例使用了Spring Boot来快速搭建框架，但是SSM框架整合SpringMVC的步骤与之类似。希望这个示例能够帮助到你。

1. pom.xml文件中的依赖配置：

<dependencies>
    <!-- Spring Boot web starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <!-- Spring Boot test starter -->
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
    </dependency>
    <!-- MyBatis starter -->
    <dependency>
        <groupId>org.mybatis.spring.boot</groupId>
        <artifactId>mybatis-spring-boot-starter</artifactId>
        <version>2.1.4</version>
    </dependency>
    <!-- MySQL connector -->
    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>8.0.26</version>
    </dependency>
</dependencies>

2. application.properties配置文件中的配置项：

# 数据源配置
spring.datasource.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=GMT%2B8
spring.datasource.username=root
spring.datasource.password=123456
# MyBatis配置
mybatis.mapper-locations=classpath:mapper/*.xml
mybatis.type-aliases-package=com.example.demo.entity
# Spring MVC配置
spring.mvc.view.prefix=/WEB-INF/views/
spring.mvc.view.suffix=.jsp

3. Spring的配置文件（application.xml）中的配置：

<!-- 数据源配置 -->
<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
    <property name="url" value="${spring.datasource.url}"/>
    <property name="username" value="${spring.datasource.username}"/>
    <property name="password" value="${spring.datasource.password}"/>
</bean>

<!-- MyBatis配置 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
    <property name="dataSource" ref="dataSource"/>
    <property name="typeAliasesPackage" value="com.example.demo.entity"/>
    <property name="mapperLocations" value="classpath:mapper/*.xml"/>
</bean>

<bean id="mapperScannerConfigurer" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
    <property name="basePackage" value="com.example.demo.mapper"/>
</bean>

<!-- 事务配置 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
    <property name="dataSource" ref="dataSource"/>
</bean>
<tx:annotation-driven transaction-manager="transactionManager"/>

4. SpringMVC的配置文件（springmvc.xml）中的配置：

<!-- ViewResolver配置 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="${spring.mvc.view.prefix}"/>
    <property name="suffix" value="${spring.mvc.view.suffix}"/>
</bean>

<!-- 静态资源配置 -->
<mvc:resources location="/static/**" mapping="/static/**"/>

<!-- RequestMappingHandlerMapping配置 -->
<mvc:annotation-driven/>

5. Mapper接口和Mapper.xml文件的实现：

UserMapper.java

public interface UserMapper {
    User getUserById(int id);
}

UserMapper.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.example.demo.mapper.UserMapper">
    <select id="getUserById" parameterType="int" resultType="com.example.demo.entity.User">
        select * from user where id = #{id}
    </select>
</mapper>

6. Controller类的实现：

@Controller
@RequestMapping("/user")
public class UserController {

    @Autowired
    private UserMapper userMapper;

    @GetMapping("/{id}")
    @ResponseBody
    public User getUserById(@PathVariable int id) {
        return userMapper.getUserById(id);
    }
}

以上就是一个简单的SSM框架整合SpringMVC的代码示例。希望能够对你有所帮助。
