Intellij Idea創建基於Maven的SpringMVC+MyBatis項目

本文轉載自查看原文 2018-01-04 16:50 1823

前言：SpringMVC是一款輕量級的Web開發框架，非常有利於新手上手，對於持久化層，目前可選擇的是Hibernate和Mybatis，而Mybatis的學習曲線較為平整，因此本文介紹了利用Intellij Idea創建基於Maven的SpringMVC／MyBatis的項目，該項目實現了簡單的用戶插入和導出，其實什么項目無所謂，主要目的還是供大家掌握MyBatis和SpringMVC的實現過程。

完成本文的項目創建，你需要以下軟件的支持：

軟件	版本
JDK	1.6+
Tomcat	7+
Maven	2+
Mysql	5+
Intellij Idea	14.+

一新建項目

在你的某一個project下：

File->New->Module

然后如下圖所示，選中Maven支持：

點擊Next到下一步，並填寫項目名：

再下一步：

選擇Maven的版本，一般使用默認的版本即可！
一路點擊Next即可，第一次建立Maven項目需要等待IDE創建

二配置文件

等待項目創建完畢，目前整個項目結構如下：

然后開始創建文件夾和項目的配置文件。
1. 首先再main下創建java文件夾，並標記位源文件目錄(Sources Root)：

在java目錄下創建四個package：

com.zhaoyh.controller
com.zhaoyh.storage
com.zhaoyh.service
com.zhaoyh.model

1.在resources文件夾下新建mapper,spring文件夾和application.properties，mybatis-config.xml兩個文件。
並在spring文件夾下面新建三個配置文件：

spring-service.xml
spring-storage.xml
spring-web.xml

1.刪除WEB-INF下面的index.jsp，新建VM文件夾，並在VM文件夾下面新建index.vm模版文件。

2.此時整個項目的目錄結構如下：

三文件內容和Java方法

1.model包下新建User.java

package com.zhaoyh.model;

/**
 * Created by zhaoyh on 2017/5/26.
 */
public class User {

    private long id;
    private String name;
    private String phone;

    public User() {
    }

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

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

    public long getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }
}

1.storage下新建UserStorage.java接口，內容如下：

package com.zhaoyh.storage;

import com.zhaoyh.model.User;
import org.apache.ibatis.annotations.Param;

import java.util.List;

/**
 * Created by zhaoyh on 2017/5/26.
 */
public interface UserStorage {

    /**
     * 插入用戶
     * @param userName
     * @param phone
     */
    void addUser(@Param("name") String userName, @Param("phone") String phone);

    /**
     * 查詢用戶列表
     * @param phone
     * @return
     */
    List<User> queryUserByPhone(@Param("phone") String phone);

}

1.在service包下新建IUserServe.java,UserService.java兩個文件，內容分別是：

package com.zhaoyh.service;

import com.zhaoyh.model.User;

import java.util.List;

/**
 * Created by zhaoyh on 2017/5/26.
 */
public interface IUserService {

    void addUser(User user);

    List<User> getUserByPhone(String phone);
}

package com.zhaoyh.service;

import com.zhaoyh.model.User;
import com.zhaoyh.storage.UserStorage;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import java.util.List;

/**
 * Created by zhaoyh on 2017/5/26.
 */
@Service
public class UserService implements IUserService {

    @Autowired
    private UserStorage userStorage;

    public void addUser(User user) {
        userStorage.addUser(user.getName(), user.getPhone());
    }

    public List<User> getUserByPhone(String phone) {
        return userStorage.queryUserByPhone(phone);
    }
}

1.controller包下新建MainController.java和BaseController.java文件，內容分別是：

package com.zhaoyh.controller;

import com.zhaoyh.model.User;
import com.zhaoyh.service.IUserService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.List;

/**
 * Created by zhaoyh on 2017/5/26.
 */
@Controller
public class MainController extends BaseController {

    @Autowired
    private IUserService userService;

    public static final String INDEX = "index";

    @RequestMapping(value = "/", method = RequestMethod.GET)
    public ModelAndView index(HttpServletRequest request, HttpServletResponse response) {

        User user = new User("zhaoyh", "18811721028");
        userService.addUser(user);

        List<User> userList = userService.getUserByPhone("18811721028");
        System.out.println("......" + userList.size());

        return innerCreateModelAndView(INDEX);
    }


}

package com.zhaoyh.controller;

import org.springframework.web.servlet.ModelAndView;

import java.util.HashMap;
import java.util.Map;

/**
 * Created by zhaoyh on 2017/5/26.
 */
public class BaseController {

    /**
     * 生成視圖，用於繼承
     * @param view
     */
    protected ModelAndView innerCreateModelAndView (String view, Object... objects) {
        assert (objects.length % 2) == 0;
        Map<String, Object> modelMap = new HashMap<String, Object>();
        for (int i = 0; i < objects.length; i++) {
            String name = (String) objects[i++];
            modelMap.put(name, objects[i]);
        }
        return new ModelAndView(view, modelMap);
    }
}

1.mapper文件夾下新建UserStorage.xml文件：

<?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.zhaoyh.storage.UserStorage">

    <select id="queryUserByPhone" resultType="com.zhaoyh.model.User">
        SELECT *
        FROM user
        WHERE
        phone= #{phone}
    </select>


    <insert id="addUser">
        INSERT INTO user (name,phone)
        VALUES (#{name},#{phone})
    </insert>

</mapper>

1.在你的數據庫中增加user表，插入語句如下：

create table user
(
    id bigint auto_increment
        primary key,
    name varchar(50) null,
    phone varchar(20) null
);

此時完整的項目結構如圖：

四配置編譯運行

1.把pom.xml中替換內容如下：

1.web.xml中的內容替換為：

  </servlet-mapping>


</web-app>

1.index.vm中增加簡單的顯示語句即可：

<h2>SSM Test</h2>

1.myatis-config.xml中修改為：

<?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">

    <settings>
        <!--使用jdbc的getGeneratekeys獲取自增主鍵值-->
        <setting name="useGeneratedKeys" value="true"/>

        <!--使用列別名替換別名　　默認true-->
        <setting name="useColumnLabel" value="true"/>

        <!--開啟駝峰命名轉換Table:create_time到 Entity(createTime)-->
        <setting name="mapUnderscoreToCamelCase" value="true"/>

    </settings>
</configuration>

application.properties文件中配置數據庫鏈接屬性：

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://XXX:3306/databaseName?useUnicode=true&characterEncoding=utf8
jdbc.username=XXX
jdbc.password=XXX

druid.pool.size.max=20
druid.pool.size.min=3
druid.pool.size.init=1

spring-web.xml中配置Spring的屬性：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    -->
    <mvc:annotation-driven/>

    <!--靜態資源默認servlet配置

    <!--配置VM　顯示ViewResolver-->
    <bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">

        <property name="suffix" value=".vm" />
        <property name="contentType"><value>text/html;charset=UTF-8</value></property>
    </bean>


</beans>

在spring-storage.xml中配置數據連接：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd">

    <!--1、配置數據庫相關參數-->
    <context:property-placeholder location="classpath:application.properties" ignore-unresolvable="true"/>

    <!--2.數據源druid -->

        <property name="password" value="${jdbc.password}" />

        <!-- 配置初始化大小、最小、最大 -->
        <property name="initialSize" value="${druid.pool.size.init}" />
        <property name="minIdle" value="${druid.pool.size.min}" />
        <property name="maxActive" value="${druid.pool.size.max}" />

        <!-- 配置監控統計攔截的filters，wall用於防止sql注入，stat用於統計分析 -->

application.properties文件中配置數據庫鏈接屬性：

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://XXX:3306/databaseName?useUnicode=true&characterEncoding=utf8
jdbc.username=XXX
jdbc.password=XXX

druid.pool.size.max=20
druid.pool.size.min=3
druid.pool.size.init

spring-web.xml中配置Spring的屬性：

<?xml version="1.0" encoding="UTF-8"?>
