Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建

mysqlSpringMVCMavenmybatis项目 搭建
2023-09-11 14:14:09 时间

这篇文章主要解说使用eclipse对Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建过程。包含里面步骤和里面的配置文件怎样配置等等都会具体说明。

假设还没有搭建好环境（主要是Maven+MySQL的配置）的猿友能够參考博主曾经的一篇文章：
http://blog.csdn.net/u013142781/article/details/50300233

接下来立即进入项目搭建过程：

1、创建表，并插入数据：

CREATE TABLE `t_user` (
  `USER_ID` int(11) NOT NULL AUTO_INCREMENT,
  `USER_NAME` char(30) NOT NULL,
  `USER_PASSWORD` char(10) NOT NULL,
  PRIMARY KEY (`USER_ID`),
  KEY `IDX_NAME` (`USER_NAME`)
) ENGINE=InnoDB AUTO_INCREMENT=11 DEFAULT CHARSET=utf8
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (1, 'luoguohui', '123456');
INSERT INTO t_user (USER_ID, USER_NAME, USER_PASSWORD) VALUES (2, 'zhangsan', '123456');

2、Maven工程创建

3、选择高速框架

4、输出项目名，包（Packaging。假设仅仅是普通的项目，选jar就好了。假设是web项目就选war，这里是web项目，所以选择war）

这里写图片描写叙述

5、创建好的文件夹例如以下：

6、加入包的依赖，编辑pom.xml文件加入例如以下依赖：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        </dependency>
    </dependencies>

</project>

7、配置文件：

这里写图片描写叙述

7.1、mybatis包下加入mybatis-config.xml文件（mybatis配置文件）：

<?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>    
</configuration>

7.2、properties包下加入jdbc.properties文件（数据源配置文件）：

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/luo
jdbc_username=root
jdbc_password=root

7.3、mapper包下userMapper.xml配置文件（表映射文件）：

<?
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.luo.dao.UserDao">
<!--设置domain类和数据库中表的字段一一相应，注意数据库字段和domain类中的字段名称不致，此处一定要！
-->
    <resultMap id="BaseResultMap" type="com.luo.domain.User">
        <id column="USER_ID" property="userId" jdbcType="INTEGER" />
        <result column="USER_NAME" property="userName" jdbcType="CHAR" />
        <result column="USER_PASSWORD" property="userPassword" jdbcType="CHAR" />
    </resultMap>
    <!-- 查询单条记录 -->
    <select id="selectUserById" parameterType="int" resultMap="BaseResultMap">
        SELECT * FROM t_user WHERE USER_ID = #{userId}
    </select>
</mapper>

7.4、spring配置文件application.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:aop="http://www.springframework.org/schema/aop"
    xsi:schemaLocation="  
           http://www.springframework.org/schema/beans  
           http://www.springframework.org/schema/beans/spring-beans-3.0.xsd  
           http://www.springframework.org/schema/aop  
           http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
           http://www.springframework.org/schema/context  
           http://www.springframework.org/schema/context/spring-context-3.0.xsd">

     <!-- 引入jdbc配置文件 -->  
     <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
               <value>classpath:properties/*.properties</value>
                <!--要是有多个配置文件，仅仅需在这里继续加入就可以 -->
            </list>
        </property>
    </bean>



    <!-- 配置数据源 -->
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <!-- 不使用properties来配置 -->
        <!-- <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
            <property name="url" value="jdbc:mysql://localhost:3306/learning" /> 
            <property name="username" value="root" /> 
            <property name="password" value="christmas258@" /> -->
       <!-- 使用properties来配置 -->
        <property name="driverClassName">
            <value>${jdbc_driverClassName}</value>
        </property>
        <property name="url">
            <value>${jdbc_url}</value>
        </property>
        <property name="username">
            <value>${jdbc_username}</value>
        </property>
        <property name="password">
            <value>${jdbc_password}</value>
        </property>
    </bean>

    <!-- 自己主动扫描了全部的XxxxMapper.xml相应的mapper接口文件，这样就不用一个一个手动配置Mpper的映射了，仅仅要Mapper接口类和Mapper映射文件相应起来就能够了。 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage"
            value="com.luo.dao" />
    </bean>

    <!-- 配置Mybatis的文件 。mapperLocations配置**Mapper.xml文件位置。configLocation配置mybatis-config文件位置-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>  
        <property name="configLocation" value="classpath:mybatis/mybatis-config.xml" />
        <!-- <property name="typeAliasesPackage" value="com.tiantian.ckeditor.model" 
            /> -->
    </bean>

    <!-- 自己主动扫描注解的bean -->
    <context:component-scan base-package="com.luo.service" />

</beans>

8、接口和类的配置：

这里写图片描写叙述

8.1、com.luo.domain下加入User.java文件：

package com.luo.domain;

public class User {

    private Integer userId;  
    private String userName;  
    private String userPassword;  


    public Integer getUserId() {  
        return userId;  
    }  

    public void setUserId(Integer userId) {  
        this.userId = userId;  
    }  

    public String getUserName() {  
        return userName;  
    }  

    public void setUserName(String userName) {  
        this.userName = userName;  
    }  

    public String getUserPassword() {  
        return userPassword;  
    }  

    public void setUserPassword(String userPassword) {  
        this.userPassword = userPassword;  
    }  

}

8.2、com.luo.dao下加入UserDao.java文件：

package com.luo.dao;

import com.luo.domain.User;

public interface UserDao {

    /**
     * @param userId
     * @return User
     */
    public User selectUserById(Integer userId);  

}

8.3、com.luo.service下加入UserService.java接口和UserServiceImpl实现类：

package com.luo.service;

import com.luo.domain.User;

public interface UserService {
    User selectUserById(Integer userId);  
}

package com.luo.service;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import com.luo.dao.UserDao;
import com.luo.domain.User;

@Service  
public class UserServiceImpl implements UserService {

    @Autowired  
    private UserDao userDao;  

    public User selectUserById(Integer userId) {  
        return userDao.selectUserById(userId);  

    }  
}

9、单元測试

这里写图片描写叙述

9.1、com.luo.baseTest下加入SpringTestCase.java：

package com.luo.baseTest;

import org.junit.runner.RunWith;  
import org.springframework.test.context.ContextConfiguration;  
import org.springframework.test.context.junit4.AbstractJUnit4SpringContextTests;  
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;  

//指定bean注入的配置文件  
@ContextConfiguration(locations = { "classpath:application.xml" })  
//使用标准的JUnit @RunWith凝视来告诉JUnit使用Spring TestRunner  
@RunWith(SpringJUnit4ClassRunner.class)  
public class SpringTestCase extends AbstractJUnit4SpringContextTests {

}

9.2、com.luo.service加入UserServiceTest.java：

package com.luo.service;

import org.junit.Test;  
import org.springframework.beans.factory.annotation.Autowired;  
import com.luo.baseTest.SpringTestCase;  
import com.luo.domain.User;

public class UserServiceTest extends SpringTestCase {

    @Autowired  
    private UserService userService; 

    @Test  
    public void selectUserByIdTest(){  
        User user = userService.selectUserById(1);  
        System.out.println(user.getUserName() + ":" + user.getUserPassword());
    }  
}

9.3、执行单元測试，UserServiceTest右键Run As –>Junit Test，执行结果：

这里写图片描写叙述

以下加入springmvc。并转换maven工程为web项目

10、转换成web项目：

假设上面webapp为空的，说明这个项目还不是web项目：

这里写图片描写叙述

接下来打开例如以下页面。将红框里面的勾去掉，确定（OK）：

这里写图片描写叙述

然后又一次打开刚刚那个页面。把Dynamic web Module勾上，就会看到红框的内容。点击：

这里写图片描写叙述

然后配置例如以下：

这里写图片描写叙述

那么webapp下就会生成这些东西：

这里写图片描写叙述

11、配置springmvc

11.1、pom.xml文件加入依赖，改动后配置例如以下：

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.luo</groupId>
  <artifactId>first_maven_project</artifactId>
  <version>0.0.1-SNAPSHOT</version>
  <packaging>war</packaging>

  <properties>
        <!-- spring版本号号 -->
        <spring.version>3.2.8.RELEASE</spring.version>
        <!-- junit版本号号 -->
        <junit.version>4.10</junit.version>
        <!-- mybatis版本号号 -->
        <mybatis.version>3.2.1</mybatis.version>
  </properties>

  <dependencies>
        <!-- 加入Spring依赖 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-webmvc</artifactId>

            <artifactId>spring-context</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context-support</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aop</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-aspects</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-tx</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-jdbc</artifactId>
            <version>${spring.version}</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>${spring.version}</version>
        </dependency>

        <!--单元測试依赖 -->
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>${junit.version}</version>
            <scope>test</scope>
        </dependency>

        <!--spring单元測试依赖 -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
            <scope>test</scope>
        </dependency>

        <!--mybatis依赖 -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>
            <version>${mybatis.version}</version>
        </dependency>

        <!-- mybatis/spring包 -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis-spring</artifactId>
            <version>1.2.0</version>
        </dependency>

        <!-- mysql驱动包 -->
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.29</version>
        </dependency>

        <!-- javaee-api包 注意和项目使用的JDK版本号相应 -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>  

        <!-- javaee-web-api包 注意和项目使用的JDK版本号相应 -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-web-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>  

    </dependencies>

</project>

事实上也就添加了以下两个

<!-- javaee-api包 注意和项目使用的JDK版本号相应 -->
<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

<!-- javaee-web-api包 注意和项目使用的JDK版本号相应 -->
<dependency>
    <groupId>javax</groupId>
    <artifactId>javaee-web-api</artifactId>
    <version>6.0</version>
    <scope>provided</scope>
</dependency>

11.2、在src/main/resource中加入springmvc文件夹，然后加入文件spring-mvc.xml。内容例如以下：

<?
xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
  xmlns:p="http://www.springframework.org/schema/p"
  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-3.2.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.2.xsd
    http://www.springframework.org/schema/mvc
    http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd">

   <mvc:annotation-driven /> 
   <!-- 扫描controller（controller层注入） -->
   <context:component-scan base-package="com.luo.controller"/>  

   <!-- 对模型视图加入前后缀 -->
   <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"
      p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>
</beans>

11.3、配置web.xml

<?

11.4、加入index.jsp，在src/main/webapp/WEB-INF下新建一个文件夹view,加入一个index.jsp，内容例如以下：

这里写图片描写叙述

<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<html>
<body>
<h2>Hello World!</h2>
用户名： ${user.userName}<br>
 密码：${user.userPassword}<br>
</body>
</html>

11.5、写controller

这里写图片描写叙述

在src/main/java下新建一个包com.luo.controller.然后新建一个类UserController.java,其内容例如以下

package com.luo.controller;

import javax.annotation.Resource;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
import com.luo.domain.User;
import com.luo.service.UserService;

@Controller  
public class UserController {  

    @Resource  
    private UserService userService;  

    @RequestMapping("/")    
    public ModelAndView getIndex(){      
        ModelAndView mav = new ModelAndView("index");   
        User user = userService.selectUserById(1);  
        mav.addObject("user", user);   
        return mav;    
    }    
}

11.6 执行！！

！！完毕！

12、源代码下载

13、可能会遇到的错

之前有个兄弟依照我的配置，可是发现pom.xml文件报例如以下错误：

Cannot detect Web Project version. Please specify version of Web Project through <version> configuration property of war plugin. E.g.: <plugin> <artifactId>maven-war-plugin</artifactId> <configuration> <version>3.0<ersion> </configuration> </plugin>

解决方式是，例如以下的三个地方jdk版本号须要保持一致：

1、项目右键->属性->Java Compiler：

2、项目右键->属性->Project Facets：

3、假设pom.xml配置了例如以下的插件的话：

<build>
 <plugins>
    <plugin>
      <artifactId>maven-compiler-plugin</artifactId>
      <configuration>
        <source>1.7</source>
        <target>1.7</target>
      </configuration>
    </plugin>
    <plugin>
      <artifactId>maven-war-plugin</artifactId>
      <version>2.4</version>
      <configuration>
        <version>3.0</version>
      </configuration>
    </plugin>
  </plugins>
  <finalName>webserver</finalName>
</build>

这里也要跟上面两个保持一致：
