1. 建表語句及插入數據

CREATE TABLE `book_user` (
  user_id INT(11) NOT NULL AUTO_INCREMENT,
  user_name VARCHAR(50) COLLATE utf8_unicode_ci NOT NULL,
  user_password CHAR(10) COLLATE utf8_unicode_ci NOT NULL,
  PRIMARY KEY (`user_id`),
  KEY `user_name` (`user_name`)
) ENGINE=INNODB AUTO_INCREMENT=10000003 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci

INSERT INTO book_user(user_name, user_password) VALUES(‘user1‘, ‘user1.‘),(‘user2‘, ‘user2.‘);

2. Maven( [‘me?v(?)n])

3. 選擇快速框架

4. 輸出項目名，包（Packaging，如果只是普通的項目，選jar就好了，如果是web項目就選war，這裏是web項目，所以選擇war）

5. 創建好的目錄如下：

6.添加包的依賴，編輯pom.xml文件添加如下依賴：

<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.創建好的目錄如下：

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>

7.2properties包下添加jdbc.properties文件（數據源配置文件）：

jdbc_driverClassName=com.mysql.jdbc.Driver

jdbc_url=jdbc:mysql://localhost:3306/web_test

jdbc_username=root

jdbc_password=Aa111111

7.3mapper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.hlx.dao.UserDao">

<!--設置domain類和數據庫中表的字段一一對應，註意數據庫字段和domain類中的字段名稱不致，此處一定要！-->

<resultMap id="BaseResultMap" type="com.hlx.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>

<!-- 查詢單條記錄 -->

<select id="selectUserById" parameterType="int" resultMap="BaseResultMap">

SELECT * FROM book_user WHERE USER_ID = #{userId}

</select>

</mapper>

7.4spring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"

/> -->

</bean>

<!-- 自動掃描註解的bean -->

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

</beans>

8.接口和類的配置：

8.1com.hlx.domain下添加User.Java文件：

package com.hlx.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;

}

}

8.2com. hlx.dao下添加UserDao.java文件：

package com.hlx.dao;

import com.hlx.domain.User;

public interface UserDao {

/**

*

* @param userId

* @return

*/

public User selectUserById(Integer userId);

}

8.3com.hlx.service下添加UserService.java接口和UserServiceImpl實現類：

package com.hlx.service;

import com.hlx.domain.User;

public interface UserService {

public User selectUserById(Integer userId);

}

package com.hlx.service;

import org.springframework.beans.factory.annotation.Autowired;

import org.springframework.stereotype.Service;

import com.hlx.dao.UserDao;

import com.hlx.domain.User;

@Service

public class UserServiceImpl implements UserService {

@Autowired

private UserDao userDao;

public User selectUserById(Integer userId) {

return userDao.selectUserById(userId);

}

}

9.單元測試：

9.1com.hlx.baseTest下添加SpringTestCase.java：

package com.hlx.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註入的配置文件

@ContextConfiguration(locations= {"classpath:application.xml"})

//使用標準的JUnit @RunWith註釋來告訴JUnit使用Spring TestRunner

@RunWith(SpringJUnit4ClassRunner.class)

public class SpringTestCase extends AbstractJUnit4SpringContextTests {

}

9.2com.hlx.service添加UserServiceTest.java：

package com.hlx.service;

import org.junit.Test;

import org.springframework.beans.factory.annotation.Autowired;

import com.hlx.baseTest.SpringTestCase;

import com.hlx.domain.User;

public class UserServiceTest extends SpringTestCase {

@Autowired

private UserService userService;

@Test

public void selectUserByIdTest(){

User user = userService.selectUserById(10000003);

System.out.println(user.getUserName() + ":" + user.getUserPassword());

}

}

9.3運行單元測試，UserServiceTest右鍵Run As –>Junit Test，運行結果：

下面加入springMVC，並轉換maven工程為web項目

10.轉換成web項目：

如果上面webapp為空的，說明這個項目還不是web項目：

接下來打開如下頁面。將紅框裏面的勾去掉，確定（OK）：

然後重新打開剛剛那個頁面，把Dynamic web Module勾上(顯示需要更高的java版本，但調整java版本後依舊顯示更高版本；所以在這裏就將Dynamic Web Module版本調低)，就會看到紅框的內容，點擊：

然後配置如下：

那麽webapp下就會生成這些東西：

11.配置springmvc：

11.1在pom.xml增加兩個依賴：

<!-- javaee-api包 註意和項目使用的JDK版本對應 -->

<dependency>

<groupId>javax</groupId>

<artifactId>javaee-api</artifactId>

<version>6.0</version>

<scope>provided</scope>

</dependency>

<!-- javaee-web-api包 註意和項目使用的JDK版本對應 -->

<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文件夾，然後添加文件spring-mvc.xml，內容如下：

<?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 />

<!-- 掃描controller（controller層註入） -->

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

<!-- 對模型視圖添加前後綴 -->

<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 id="WebApp_ID" version="2.5"

xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

<error-page>

<!-- 內部錯誤 -->

<error-code>500</error-code>

<location>/WEB-INF/errorpage/500.jsp</location>

</error-page>

</web-app>

11.4添加index.jsp，在src/main/webapp/WEB-INF下新建一個文件夾view,添加一個index.jsp，內容如下：

<%@ page language="java" contentType="text/html; charset=UTF-8"

pageEncoding="UTF-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

<title>Insert title here</title>

</head>

<body>

<h2>Hello World!</h2>

用戶名： ${user.userName}

密碼：${user.userPassword}

</body>

</html>

11.5寫controller

package com.hlx.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.hlx.domain.User;

import com.hlx.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;

}

}

12.Eclipse配置tomcat

配置後發現工程沒有部署上，所以修改相關路徑

13.備註說明

13.1主要參考文檔

http://mp.weixin.qq.com/s?__biz=MjM5NzMyMjAwMA==&mid=2651477246&idx=2&sn=f30d754635ec5a3f589574707c12c263&scene=21#wechat_redirect

13.2用註解Resource時出錯，本人改變了javaSE版本

13.3可能會遇到的錯

之前有個兄弟按照我的配置，但是發現pom.xml文件報如下錯誤：

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>

解決方案是，如下的三個地方jdk版本需要保持一致：

1、項目右鍵->屬性->Java Compiler：

2、項目右鍵->屬性->Project Facets：

3、如果pom.xml配置了如下的插件的話：\

<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>

這裏也要跟上面兩個保持一致：

Spring+SpringMVC+Maven+Mybatis+MySQL項目搭建
