---恢復內容開始---
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( ['meɪv(ə)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，這里是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，注意數據庫字段和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"

<property name="basePackage"

</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>
<!-- 自動掃描注解的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注入的配置文件
@ContextConfiguration(locations= {"classpath:application.xml"})
//使用標准的JUnit @RunWith注釋來告訴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。將紅框里面的勾去掉，確定（OK）：
然后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版本后依舊顯示更高版本；所以在這里就將Dynamic Web Module版本調低)，就會看到紅框的內容，點擊：
然后配置如下：
那么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 注意和項目使用的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 注意和項目使用的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，然后添加文件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層注入） -->
<context:component-scan base-package="com.hlx.controller"/>
<!-- 對模型視圖添加前后綴 -->
<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
配置后發現工程沒有部署上，所以修改相關路徑
13.備注說明
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用注解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>
這里也要跟上面兩個保持一致：
