---恢复内容开始---

1. 建表语句及插入数据

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. 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.创建好的目录如下:

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(数据源配置文件):

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">

<!--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.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>

<!-- 查询单条记录 -->

<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"

/> -->

</bean>

<!-- 自动扫描注解的bean -->

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

</beans>

8.接口和类的配置:

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实现类:

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.单元测试:

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"})

//使用标准的JUnit @RunWith注释来告诉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(显示需要更高的java版本,但调整java版本后依旧显示更高版本;所以在这里就将Dynamic Web Module版本调低),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在pom.xml增加两个依赖:

<!-- 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.hlx.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 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">

<display-name>Archetype Created Web Application</display-name>

<error-page>

<!-- 内部错误 -->

<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"%>

<!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>

用户名: ${user.userName}

密码:${user.userPassword}

</body>

</html>

11.5写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

配置后发现工程没有部署上,所以修改相关路径

13.备注说明

13.1主要参考文档

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

13.2用注解Resource时出错,本人改变了javaSE版本

13.3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:

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-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:
