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

这篇文章主要讲解使用eclipse对Spirng+SpringMVC+Maven+Mybatis+MySQL项目搭建过程,包括里面步骤和里面的配置文件如何配置等等都会详细说明。

如果还没有搭建好环境(主要是Maven+MySQL的配置)的猿友可以参考博主以前的一篇文章:
http://blog.csdn.net/u013142781/article/details/50300233

接下来马上进入项目搭建过程:

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

这里写图片描述

3、选择快速框架

这里写图片描述

4、输出项目名,包(Packaging,如果只是普通的项目,选jar就好了,如果是web项目就选war,这里是web项目,所以选择war)

这里写图片描述

5、创建好的目录如下:

这里写图片描述

6、添加包的依赖,编辑pom.xml文件添加如下依赖:

<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:

这里写图片描述

7.1、mybatis包下添加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包下添加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对应,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,只需在这里继续添加即可 -->
            </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">

        <property name="username">
            <value>${jdbc_username}</value>
        </property>
        <property name="password">
            <value>${jdbc_password}</value>
        </property>
    </bean>

    <!-- 自动扫描了所有的XxxxMapper.xml对应的mapper接口文件,这样就不用一个一个手动配置Mpper的映射了,只要Mapper接口类和Mapper映射文件对应起来就可以了。 -->
    <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:

这里写图片描述

8.1、com.luo.domain下添加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下添加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下添加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、单元测试

这里写图片描述

9.1、com.luo.baseTest下添加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注释来告诉JUnit使用Spring TestRunner  
@RunWith(SpringJUnit4ClassRunner.class)  
public class SpringTestCase extends AbstractJUnit4SpringContextTests {

}

9.2、com.luo.service添加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、运行单元测试,UserServiceTest右键Run As –>Junit Test,运行结果:

这里写图片描述


下面加入springmvc,并转换maven工程为web项目


10、转换成web项目:

如果上面webapp为空的,说明这个项目还不是web项目:

这里写图片描述

接下来打开如下页面。将红框里面的勾去掉,确定(OK):

这里写图片描述

然后重新打开刚刚那个页面,把Dynamic web Module勾上,就会看到红框的内容,点击:

这里写图片描述

然后配置如下:

这里写图片描述

那么webapp下就会生成这些东西:

这里写图片描述

11、配置springmvc

11.1、pom.xml文件添加依赖,修改后配置如下:

<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">

        <junit.version>4.10</junit.version>
        <!-- mybatis版本号 -->
        <mybatis.version>3.2.1</mybatis.version>
  </properties>

  <dependencies>
        <!-- 添加Spring依赖 -->

        </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>

            <version>${junit.version}</version>
            <scope>test</scope>
        </dependency>

        <!--spring单元测试依赖 -->
        <dependency>

            <artifactId>spring-test</artifactId>
            <version>${spring.version}</version>
            <scope>test</scope>
        </dependency>

        <!--mybatis依赖 -->
        <dependency>
            <groupId>org.mybatis</groupId>
            <artifactId>mybatis</artifactId>

        </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版本对应 -->  
        <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版本对应 -->  
        <dependency>  
            <groupId>javax</groupId>  
            <artifactId>javaee-web-api</artifactId>  
            <version>6.0</version>  
            <scope>provided</scope>  
        </dependency>  

    </dependencies>

</project>

其实也就增加了下面两个

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

11.2、在src/main/resource中添加springmvc文件夹,然后添加文件spring-mvc.xml,内容如下:

<?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"/>  

   <!-- 对模型视图添加前后缀 -->
   <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

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
    id="WebApp_ID" version="2.5">
    <display-name>Archetype Created Web Application</display-name>
   <!-- 起始欢迎界面 -->
    <welcome-file-list>
        <welcome-file>index.jsp</welcome-file>
    </welcome-file-list>

    <!-- 读取spring配置文件 -->

11.4、添加index.jsp,在src/main/webapp/WEB-INF下新建一个文件夹view,添加一个index.jsp,内容如下:

这里写图片描述

<%@ 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,其内容如下

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 运行!!!!完成!

12、源码下载

http://download.csdn.net/detail/u013142781/9376381

13、可能会遇到的错

之前有个兄弟按照我的配置,但是发现pom.xml文件报如下错误:

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>

解决方案是,如下的三个地方jdk版本需要保持一致:

1、项目右键->属性->Java Compiler:

这里写图片描述

2、项目右键->属性->Project Facets:

这里写图片描述

3、如果pom.xml配置了如下的插件的话:

<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:
