MAVEN+spring+springmvc+mybatis+mysql框架搭建+git管理

2016-01-07 14:09 357 查看

1、MAVEN下载并配置好，在命令提示符（cmd）中输入mvn -version 出来了maven版本即配置成功

2、在eclipse中新建maven工程如下：

选择建立webapp选项，点击next。groupid和Artifact id可以随便填写

3.建立好会出现src/main/java，src/main/resources，src/test/java，src/test/resources，如果缺少可以自己新建对应的文件夹，记得是新建source folder而不是folder，然后在buildpath中点击source，配置好每个文件夹的output folder：XXX的默认out folder路径。

4.项目框架的基本结构如下：

在src/main/java文件夹中，新建包com.maven.spring.model(存放javabean),

com.maven.spring.dao（存放spring与mybatis连接接口）,

cn.maven.spring.service（service接口）,

com.maven.spring.service.impl（service接口的实现），

com.maven.spring.controller（存放控制层controller）

在src/main/resource文件夹中，新建包conf（存放配置文件），

mapper（mybatis的mapper文件）

在src/test/java文件夹中，新建包cn.springmvc.test(存放测试文件)

在WEB-INF文件夹下新建jsp文件夹（存放jsp文件）

5.在maven中导入依赖包。打开pom.xml，我的pom.xml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/maven-v4_0_0.xsd">

5.在resources/conf中新建spring-mybatis.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:p="http://www.springframework.org/schema/p"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:util="http://www.springframework.org/schema/util"

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/tx http://www.springframework.org/schema/tx/spring-tx-3.2.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.2.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-3.2.xsd">
<context:component-scan base-package="com.maven.spring.Service"/>



<context:property-placeholder location="classpath:conf/jdbc.properties" />

<bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"

init-method="init" destroy-method="close">

<property name="driverClassName" value="com.mysql.jdbc.Driver" />

<property name="url" value="jdbc:mysql://localhost:3306/mysql?useUnicode=true&characterEncoding=utf-8" />

<property name="username" value="root" />

<property name="password" value="root" />



<property name="initialSize" value="0" />



<property name="maxActive" value="20" />



<property name="minIdle" value="0" />



<property name="maxWait" value="60000" />

<property name="poolPreparedStatements" value="true" />

<property name="maxPoolPreparedStatementPerConnectionSize"

value="33" />



<property name="validationQuery" value="select 1 from dual;" />

<property name="testOnBorrow" value="false" />

<property name="testOnReturn" value="false" />

<property name="testWhileIdle" value="true" />



<property name="timeBetweenEvictionRunsMillis" value="60000" />



<property name="minEvictableIdleTimeMillis" value="25200000" />



<property name="removeAbandoned" value="true" />



<property name="removeAbandonedTimeout" value="1800" />



<property name="logAbandoned" value="true" />



<property name="filters" value="mergeStat" />

</bean>



<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

<property name="dataSource" ref="dataSource"></property>

<property name="configLocation" value="classpath:conf/mybatis-config.xml"></property>

<property name="mapperLocations" value="classpath:mapper/*.xml"></property>

</bean>



<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">

<property name="basePackage" value="com.maven.spring.dao" />

<property name="sqlSessionFactory" ref="sqlSessionFactory" />

</bean>



<bean id="transactionManager"

class="org.springframework.jdbc.datasource.DataSourceTransactionManager">

<property name="dataSource" ref="dataSource" />

</bean>

</beans>

6.同样在resources/conf中新建mybatis-config.xml：

<?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>



<typeAliases>

<typeAlias alias="Student" type="com.maven.spring.model.Student"/>

</typeAliases>



</configuration>

7.在resources/mapper下新建StudentMapper.xml：（mybaits链接数据库的核心）

<?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.maven.spring.dao.StudentDAO">

<insert id="insertStudent" parameterType="Student" keyProperty="id">

insert into student(

name,

age,

aihao)

values

(

#{name},

#{age},

#{aihao})

</insert>

<select id="selectById" parameterType="int" resultType="Student">

select * from student where id=#{id}

</select>

</mapper>

8.在dao层中建立StudentDAO.java：注：不用实现，因为会和StudengMapper中的id相对应从而实现具体

package com.maven.spring.dao;

import org.springframework.stereotype.Repository;

import org.springframework.transaction.annotation.Transactional

import com.maven.spring.model.Student;

@Repository

public interface StudentDAO {

/*

* 添加新用户

*/

public int insertStudent(Student student);

/*

* 查找用户

*/

public Student selectById(int id);

}

9.在model层建立Student.java：

package com.maven.spring.model;

/*

* 学生基本信息表

*/

public class Student {

private int id;

private String name;

private int age;

private String aihao;

public int getId() {

return id;

}

public void setId(int id) {

this.id = id;

}

public String getName() {

return name;

}

public void setName(String name) {

this.name = name;

}

public int getAge() {

return age;

}

public void setAge(int age) {

this.age = age;

}

public String getAihao() {

return aihao;

}

public void setAihao(String aihao) {

this.aihao = aihao;

}

}

10.在service层建立StudentService.java：

package com.maven.spring.Service;

import com.maven.spring.model.Student;

public interface StudentService {

public int insertStudent(Student stu);

public Student selectStu(int id);

}

11.在service/impl中具体实现service层的接口：StudentServiceImpl.java：

package com.maven.spring.Service.impl;

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

import org.springframework.stereotype.Service;

import com.maven.spring.Service.StudentService;

import com.maven.spring.dao.StudentDAO;

import com.maven.spring.model.Student;

@Service

public class StudentServiceImpl implements StudentService{

@Autowired

private StudentDAO studao;

@Override

public int insertStudent(Student stu) {

// TODO Auto-generated method stub

return studao.insertStudent(stu);

}

@Override

public Student selectStu(int id) {

// TODO Auto-generated method stub

return studao.selectById(id);

}

}

12.在test中新建com.maven.spring.test包。新建StudentTest.java进行单元测试：

package com.maven.spring.test;

import org.apache.log4j.Logger;

import org.junit.Before;

import org.junit.Test;

import org.junit.runner.RunWith;

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

import org.springframework.context.ApplicationContext;

import org.springframework.context.support.ClassPathXmlApplicationContext;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import com.maven.spring.Service.StudentService;

import com.maven.spring.Service.impl.StudentServiceImpl;

import com.maven.spring.model.Student;

@RunWith(SpringJUnit4ClassRunner.class)

@ContextConfiguration(locations = {"classpath:conf/spring-mybatis.xml" })

public class StudentTest {

private static final Logger LOGGER = Logger

.getLogger(StudentTest.class);

@Autowired

private StudentService stuservice;

// public void before(){

// @SuppressWarnings("resource")

// ApplicationContext context = new ClassPathXmlApplicationContext(new String[]{"classpath:conf/spring.xml"

// ,"classpath:conf/spring-mybatis.xml"});

// stuservice = (StudentService) context.getBean("StudentServiceImpl");

// }

@Test

public void addUser(){

Student stu = new Student();

stu.setId(100);

stu.setAge(1);

stu.setName("佳佳");

stu.setAihao("听音乐");

int i=stuservice.insertStudent(stu);

System.out.println("i am print:"+i);

}

}

最后测试成功。可以从数据库中查看有没有成功完成数据插入。

现在加入springMVC：

首先建立student表。内容是id（int），age（int），name（varchar），aihao（varchar）

13.web.xml配置为： //从web.xml中加载并识别找到加载哪些配置

<web-app>

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



<context-param>

<param-name>webAppRootKey</param-name>

<param-value>maven.example.root</param-value>

</context-param>



<context-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath:conf/spring-mybatis.xml</param-value>

</context-param>



<listener>

<listener-class>org.springframework.web.util.Log4jConfigListener

</listener-class>

</listener>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>



<filter>

<filter-name>CharacterEncodingFilter</filter-name>

<filter-class>org.springframework.web.filter.CharacterEncodingFilter

</filter-class>

<init-param>

<param-name>encoding</param-name>

<param-value>UTF-8</param-value>

</init-param>

<init-param>

<param-name>forceEncoding</param-name>

<param-value>true</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>CharacterEncodingFilter</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>



<servlet>

<servlet-name>dispatcher</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet

</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>/WEB-INF/dispatcher-servlet.xml</param-value>

</init-param>

<load-on-startup>1</load-on-startup>

</servlet>

<servlet-mapping>

<servlet-name>dispatcher</servlet-name>

<url-pattern>*.do</url-pattern>

</servlet-mapping>

<welcome-file-list>

<welcome-file>index.jsp</welcome-file>

</welcome-file-list>

</web-app>

14.web.xml同级目录下建立：dispatcher-servlet

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

xmlns:aop="http://www.springframework.org/schema/aop"

xmlns:context="http://www.springframework.org/schema/context"

xmlns:mvc="http://www.springframework.org/schema/mvc"

xmlns:tx="http://www.springframework.org/schema/tx"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd">
<mvc:annotation-driven />

<context:component-scan base-package="com.maven.spring" />

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">

<property name="prefix" value="/" />

<property name="suffix" value=".jsp" />

</bean>

</beans>

15.在controller层中新建StuController.java:

package com.maven.spring.Controller;

import javax.servlet.http.HttpServletRequest;

import org.junit.runner.RunWith;

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

import org.springframework.stereotype.Controller;

import org.springframework.test.context.ContextConfiguration;

import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import org.springframework.ui.Model;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestParam;

import com.maven.spring.Service.StudentService;

import com.maven.spring.model.Student;

@Controller

public class StuController {

@Autowired

private StudentService stuservice;

@RequestMapping("stuselect")

public String getStu(@RequestParam("idno") String idno, HttpServletRequest request,Model model) {

// String dd="55555jia";

int id=Integer.parseInt(idno);

Student stu=stuservice.selectStu(id);

// if(stu.getName().equals("张三"))

// dd="666666zhen";

// request.setAttribute("stu",stu);

//request.setAttribute("dd",dd);

model.addAttribute("stu",stu);

//request.setAttribute("newUserName", newUserName);

//System.out.print("stu name is:"+stu.getName());

return "selectStu";

}

}

16.建立index.jsp：

<%@ 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=UTF-8">

<title>Insert title here</title>

</head>

<body>

<form action="stuselect.do" method="post">

请输入Id号查询：<input type="text" name="idno" />

<input type="submit" value="提交" />

<br />

</form>

</body>

</html>

17.建立selectStu.jsp

<%@ 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=UTF-8">

<title>Insert title here</title>

</head>

<body>

<p>

id:${stu.id}<br/>

name:${stu.name}</br>

age:${stu.age}</br>

aihao:${stu.aihao}</br>

</p>

</body>

</html>

最后可以从index.jsp中输入id来查找数据库中的对应的学生信息.完成搭建。

记住：网上很多教程都是右键项目-Properties-Project Facets 来转成web项目（即项目左上角有一个地球的标志），其实没必要这样，我们完成了所有的搭建之后，用git bash或者cmd 进入到我们项目用：mvn eclipse：eclipse 转成eclipse项目即可。在git bash 中mvn tomcat7：run启动tomcat。在浏览器中输入：localhost:8080即可。

点击提交即可查询到数据库中的内容。如果没有出来的话就再好好调试一下吧，程序员的工作就是不断的和bug做斗争。
