环境

1. 新建一个Maven项目（选择webapp注意不要选cocoon的）

2. 输入Name Group

3. Add Maven Property（可省略）

4. 建各种包

java和resource包都要直接双击就行了

在main包下新建test包并标记

最后附上项目里所有的包结构以及pom.xml

web.xml

5. 编写各种类

User.class

UserMapper.interface

UserService.interface

UserServiceImpl.class

UserController.class

6. 编写resources中的applicationContext.xml和springmvc.xml

applicationContext.xml

springmvc.xml

7. 启动tomcat进行测试是否整合完成

启动前建议把项目结构中modules中的spring放在同一个applicationContext中

环境

Idea
Tomcat8.0.50
jdk1.8
Mysql 5

        <filter-name>characterEncodingFilter</filter-name>
        <url-pattern>/</url-pattern>
    </filter-mapping>

5. 编写各种类

User.class

package com.hu.pojo;

public class User {

    private Integer id;
    private String name;

    public User() {
    }

    public User(Integer id, String name) {
        this.id = id;
        this.name = name;
    }

    @Override
    public String toString() {
        return "User{" +
                "id=" + id +
                ", name='" + name + '\'' +
                '}';
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

UserMapper.interface

package com.hu.mapper;

import com.hu.pojo.User;
import org.apache.ibatis.annotations.Select;
import org.springframework.stereotype.Repository;

import java.util.List;
@Repository
public interface UserMapper {

也可选择用xml文件进行CRUD

    @Select("select * from user")
    List<User> getUsers();
}

UserService.interface

package com.hu.service;

import com.hu.pojo.User;

import java.util.List;

public interface UserService {
    List<User> getUsers();
}

UserServiceImpl.class

package com.hu.service.impl;

import com.hu.mapper.UserMapper;
import com.hu.pojo.User;
import com.hu.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

@Service
public class UserServiceImpl implements UserService {

    @Autowired
    private UserMapper mapper;

    @Override
    public List<User> getUsers() {
        return mapper.getUsers();
    }
}

UserController.class

package com.hu.controller;

import com.hu.pojo.User;
import com.hu.service.UserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import java.util.List;

@Controller
public class UserController {

    @Autowired
    private UserService userService;

    @RequestMapping("/list")
    public String list(Model model) {
        List<User> users = userService.getUsers();
        model.addAttribute("users", users);
        return "list";
    }


}

6. 编写resources中的applicationContext.xml和springmvc.xml

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"

    <!--    不去扫描controller包  用于扫描.java中的mapper  注意和下面的扫描.xml的mapper区分清楚-->
    <context:component-scan base-package="com.hu">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <bean class="com.mchange.v2.c3p0.ComboPooledDataSource" id="dataSource">
        <property name="password" value="root"/>
        <property name="user" value="root"/>

        <!--        #改成自己的并补充完整  mysql8略有不同-->

        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssm"/>
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
    </bean>

    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--<property name="mapperLocations" value="mybatis/mapper/*Mapper.xml"/>//用于扫描mapper.xml文件-->
          
    </bean>

    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.hu.mapper"/>
    </bean>

</beans>

springmvc.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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context https://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc https://www.springframework.org/schema/mvc/spring-mvc.xsd">
    <!--    扫描controller包-->
    <context:component-scan base-package="com.hu.controller"/>
    <!--    开启注解-->
    <mvc:annotation-driven/>
    <!--    静态资源过滤  如果不配置这一个的话 静态资源之类的会404-->
    <mvc:default-servlet-handler/>

    <!--  视图解析器  -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="internalResourceViewResolver">
        <!--        前缀-->
        <property name="prefix" value="/WEB-INF/pages/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>


</beans>

环境

1. 新建一个Maven项目（选择webapp注意不要选cocoon的）

3. Add Maven Property（可省略）可减少maven的创建时间

4. 建各种包

java和resource包都要直接双击就行了

在main包下新建test包并标记

最后附上项目里所有的包结构以及pom.xml

web.xml

5. 编写各种类

User.class

UserMapper.interface

UserService.interface

UserServiceImpl.class

UserController.class

6. 编写resources中的applicationContext.xml和springmvc.xml

applicationContext.xml

springmvc.xml

7. 启动tomcat进行测试是否整合完成

启动前建议把项目结构中modules中的spring放在同一个applicationContext中
