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

3、选择快速框架

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）

5、创建好的目录如下：

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">

7、配置文件：

7.1、mybatis包下添加mybatis-config.xml文件（mybatis配置文件）：

  
  
<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）：

  

<mapper namespace="com.luo.dao.UserDao">

    <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>
    
    <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：

<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">

       
     <bean id="propertyConfigurer" class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
               <value>classpath:properties/*.propertiesvalue>
                
            list>
        property>
    bean>



    
    <bean id="dataSource"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        
        
       
        <property name="driverClassName">
            <value>${jdbc_driverClassName}value>
        property>

        property>
    bean>

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

    
    <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" />
        
    bean>

    
    <context:component-scan base-package="com.luo.service" />

beans>

8、接口和类的配置：

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

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：

---

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：

接下来打开如下页面。将红框里面的勾去掉，确定（OK）：

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：

然后配置如下：

那么webapp下就会生成这些东西：

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">

        dependency>

        
        <dependency>

            <scope>providedscope>  
        dependency>  

    dependencies>

project>

其实也就增加了下面两个

<dependency>
    <groupId>javaxgroupId>
    <artifactId>javaee-apiartifactId>
    <version>6.0version>
    <scope>providedscope>
dependency>


<dependency>
    <groupId>javaxgroupId>
    <artifactId>javaee-web-apiartifactId>
    <version>6.0version>
    <scope>providedscope>
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：

<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 /> 
   
   <context:component-scan base-package="com.luo.controller"/>  

   
   <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

<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"

        <location>/WEB-INF/errorpage/405.jsplocation>
    error-page>
    <error-page>
        
        <error-code>500error-code>
        <location>/WEB-INF/errorpage/500.jsplocation>
    error-page>
web-app>

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：

<%@ 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

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

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-pluginartifactId> <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：

2、项目右键->属性->Project Facets：

3、如果pom.xml配置了如下的插件的话：

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

这里也要跟上面两个保持一致：
