二、整合框架


项目结构:





pom.xml文件内容:

		<password>admin</password>
	   </configuration> 
        </plugin>
    </plugins>
    
  </build>
</project>


1.新建一个Maven WEB项目


在eclipse菜单栏中选择“File”---“News”---“Other”菜单项，就会打开如下对话窗口，在窗口中选择“Maven”节点下“Maven Project”条目，如下图所示：




点击Next




点击Next




点击Next




点击Finish




index.jsp页面报错: The superclass "javax.servlet.http.HttpServlet" was not found on the Java Build Path





原因是没加入ServletAPI所导致的，在pom.xml中加入依赖就行了。


        <!-- 加入ServletAPI -->
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>servlet-api</artifactId>
			<version>2.3</version>
			<scope>provided</scope>
		</dependency>



2.导入MySQL与Mybatis 依赖


		<!-- MySQL依赖 start -->
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
			<version>5.1.38</version>
		</dependency>

		<!-- MySQL依赖 end -->
		
		<!-- Log4j start -->
		<dependency>
			<groupId>log4j</groupId>
			<artifactId>log4j</artifactId>
			<version>1.2.17</version>
		</dependency>
		<!-- Log4j end -->
		
		<!-- 加入MyBatis 依赖 start -->
		<dependency>
			<groupId>org.mybatis</groupId>
			<artifactId>mybatis</artifactId>
			<version>3.2.5</version>
		</dependency>
		<!-- 加入MyBatis 依赖 end -->



3.写Mybatis配置文件及实体类和映射文件


新建两个包:


com.fendo.entity   ----实体包

com.fendo.dao    ----方法包


并在其中加入一个Person类和Person.xml的映射文件，和一个操作Person的接口类，以及一个测试类:






新建一个表: person




插入几条数据





实体类: person.java


package com.fendo.entity;

public class Person {

	private int pid;
	private String pname;
	private int page;
	
	private int pageIndex;
	private int pageSize;
	public int getPageIndex() {
		return pageIndex;
	}
	public void setPageIndex(int pageIndex) {
		this.pageIndex = pageIndex;
	}
	public int getPageSize() {
		return pageSize;
	}
	public void setPageSize(int pageSize) {
		this.pageSize = pageSize;
	}
	public Person() {
		super();
		// TODO Auto-generated constructor stub
	}
	public Person(int pid, String pname, int page) {
		super();
		this.pid = pid;
		this.pname = pname;
		this.page = page;
	}
	public int getPid() {
		return pid;
	}
	public void setPid(int pid) {
		this.pid = pid;
	}
	public String getPname() {
		return pname;
	}
	public void setPname(String pname) {
		this.pname = pname;
	}
	public int getPage() {
		return page;
	}
	public void setPage(int page) {
		this.page = page;
	}
	@Override
	public String toString() {
		return "Person [pid=" + pid + ", pname=" + pname + ", page=" + page + "]";
	}
	public Person(String pname, int page) {
		super();
		this.pname = pname;
		this.page = page;
	}
	
	
}


SQL操作配置文件: Person.xml


<?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.fendo.dao.PersonDao">

	<!-- 查询所有的数据 -->
	<select id="getPersons" resultType="Person">
		select * from person
	</select>
	
	<!-- 插入一条数据 -->
	<insert id="addPerson" parameterType="person">
		insert into person(pname,page) values(#{pname},#{page})
	</insert>	
</mapper>


方法接口类: PersonDao.java


package com.fendo.dao;

import java.util.List;

import com.fendo.entity.Person;


public interface PersonDao {
	
	public List<Person> getPersons();
	
	public void addPerson(Person person);
}


测试类: TestMybatis.java


package com.fendo.test;

import java.io.IOException;

import org.apache.ibatis.io.Resources;
import org.apache.ibatis.session.SqlSession;
import org.apache.ibatis.session.SqlSessionFactory;
import org.apache.ibatis.session.SqlSessionFactoryBuilder;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;

import com.fendo.dao.PersonDao;

public class TestMybatis {

	private SqlSession sqlSession;


	@Before
	public void before(){
		try {
			SqlSessionFactory sqlSessionFactory=new SqlSessionFactoryBuilder().build(Resources.getResourceAsStream("myBatisConfig.xml"));
			sqlSession = sqlSessionFactory.openSession();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
	
	@After
	public void after(){
		sqlSession.commit();
		sqlSession.close();
	}
	
	
	@Test
	public void test(){
		PersonDao personDao=sqlSession.getMapper(PersonDao.class);
		System.out.println(personDao.getPersons().size());
	}
}



4.测试(Mybatis)



点击test右键Run AS ----> Junit Test




Mybatis测试成功,下载地址: http://download.csdn.net/detail/u011781521/9714668



5.导入Spring 依赖


<!-- 初始化框架的版本号 -->
<properties>
	<spring.version>4.3.3.RELEASE</spring.version>
</properties>

		<!-- 引入Spring(包含SpringMVC) 依赖 start -->

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-core</artifactId>
			<version>${spring.version}</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-web</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-oxm</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-tx</artifactId>
			<version>${spring.version}</version>
		</dependency>


		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-jdbc</artifactId>
			<version>${spring.version}</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-webmvc</artifactId>
			<version>${spring.version}</version>
		</dependency>
		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-aop</artifactId>
			<version>${spring.version}</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-context-support</artifactId>
			<version>${spring.version}</version>
		</dependency>

		<dependency>
			<groupId>org.springframework</groupId>
			<artifactId>spring-test</artifactId>
			<version>${spring.version}</version>
		</dependency>

		<!-- 引入Spring 依赖 end -->
		
		<!-- 引用c3p0 依赖 start-->
		<dependency>
		    <groupId>com.mchange</groupId>
		    <artifactId>c3p0</artifactId>
		    <version>0.9.2.1</version>
		</dependency>
		<!-- 引用c3p0 依赖 end-->

		<!-- 引用插件依赖：MyBatis整合Spring -->
		<dependency>
		    <groupId>org.mybatis</groupId>
		    <artifactId>mybatis-spring</artifactId>
		    <version>1.3.0</version>
		</dependency>



6.写Spring 配置文件applicationContext(引入db,c3p0DataSource,SessionFactory,事物)


在src/main/resources下新建applicationContext.xml，以及db.properties配置文件


applicationContext.xml内容如下


<?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"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
		http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd">

	<!-- 引入db.properties -->
	<context:property-placeholder location="classpath:db.properties"/>

	<!-- 配置数据源c3p0 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="user" value="${uname}"></property>
		<property name="password" value="${upass}"></property>
		<property name="jdbcUrl" value="${url}"></property>
		<property name="driverClass" value="${driver_class}"></property>
		
		<!-- 初始化池子大小 -->
		<property name="initialPoolSize" value="${initPoolSize}"></property>
		
		<!-- 池子最大数 -->
		<property name="maxPoolSize" value="${maxPoolSize}"></property>
	</bean>
	
	<!-- 配置SqlSessionFactory -->
	<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 01.引入数据源 -->
		<property name="dataSource" ref="dataSource"></property>
		<!-- 02.加载MyBatis配置文件 -->
		<property name="configLocation" value="classpath:myBatisConfig.xml"></property>
		<!-- 03.加载MyBatis映射文件 -->
		<property name="mapperLocations" value="classpath:com/fendo/entity/*.xml"></property>
	</bean>
	
	
	<!-- 配置Dao接口的两种方法: 1.单个MapperFactoryBean  2.包里面的MapperScannerConfigurer-->
	
	<!-- 配置PersonDao -->
	<!-- <bean id="personDao" class="org.mybatis.spring.mapper.MapperFactoryBean">
		<property name="sqlSessionFactory" ref="sqlSessionFactory"></property>
		
		<property name="mapperInterface" value="com.zking.dao.PersonDao"></property>
	</bean> -->
	
	<!-- 配置整个包中所有的Dao接口 -->
	<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<property name="basePackage" value="com.fendo.dao"></property>
	</bean>
	
</beans>


配置Dao接口的两种方法说明







db.properties内容如下


uname=root
upass=123
driver_class=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=UTF-8

initPoolSize=5
maxPoolSize=10


把myBatisConfig.xml文件修改成如下


<?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">
  
  <!-- 类似Hibernate配置文件： hibernate.cfg.xml -->
<configuration>

<!-- 设置别名 -->
  <typeAliases>
  	<!-- 批量,默认别名为：类名Person或者person -->
  	<package name="com.fendo.entity"/>
  </typeAliases>
  
 
</configuration>


连接数据库属性哪些配置移到了applicationContext.xml文件中去了。



7.测试(Spring与Mybatis)


新建TestSpringMybatis测试类


public class TestSpringMybatis {
	public static void main(String[] args) {
		//01.加载spring配置文件
		ApplicationContext ac=new ClassPathXmlApplicationContext("applicationContext.xml");
		PersonDao personDao=(PersonDao) ac.getBean("personDao");
		
		personDao.addPerson(new Person("小小A", 10));
		
		System.out.println(personDao.getPersons().size());
	}
}


运行输出结果如下:




spring+mybatis整合成功!!!!



8.整合Spring MVC


先写一个简单的注册页面与一个注册成功页面


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>注册页面</title>
</head>
<body>
  	<form action="addPerson.action" method="post">
		pname:<input type="text" name="pname"/><br/>
		page:<input type="text" name="page"/><br/>
		<input type="submit" value="添加"/><br/>
	</form>
</body>
</html>


success.jsp


<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>    
<!-- EL表达式生效 -->
<%@ page isELIgnored="false" %>
<!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>
	<table border="1">
		<tr>
			<th>编号</th>
			<th>姓名</th>
			<th>年龄</th>
		</tr>
		<c:forEach items="${persons}" var="p">
			<tr>
				<td>${p.pid}</td>
				<td>${p.pname}</td>
				<td>${p.page}</td>
			</tr>
		</c:forEach>
	</table>
</body>
</html>


这里导入了JSTL所以要在pom.xml中引入依赖


<!-- JSTL -->
<dependency>
	<groupId>jstl</groupId>
	<artifactId>jstl</artifactId>
	<version>1.2</version>
</dependency>


9.写Controller包与Controller类


新建一个Controler包和一个PersonController类


@Controller
public class PersonController {
	
	@Autowired
	private PersonDao personDao;
	
	@RequestMapping("/addPerson")
	public ModelAndView addPerson(Person person){
		System.out.println("页面数据："+person);
		
		//加入数据
		personDao.addPerson(person);
		
		//查数据
		List<Person> persons=personDao.getPersons();
		
		//存起来
		ModelAndView modelAndView=new ModelAndView();
		modelAndView.setViewName("success");
		modelAndView.addObject("persons", persons);
		
		return modelAndView;
	}
	
}



10.写Spring MVC配置文件(springmvc.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"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd
		http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd">
	
	<!-- 扫描器 -->
	<context:component-scan base-package="com.fendo"></context:component-scan>
	
	<!-- 视图解析器 -->
	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
			<property name="suffix" value=".jsp"></property>
			<property name="prefix" value="/"></property>
	</bean>
</beans>



11.web.xml中加载配置文件(Spring,SpringMVC)

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app>
  <display-name>Archetype Created Web Application</display-name>
  
  <!-- 加载SpringMVC -->
  <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
	
  <!-- 加载Spring -->
  <!-- needed for ContextLoaderListener -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>

	<!-- Bootstraps the root web application context before servlet initialization -->
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<servlet>
		<servlet-name>springDispatcherServlet</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>classpath:springmvc.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
	</servlet>

	<!-- Map all requests to the DispatcherServlet for handling -->
	<servlet-mapping>
		<servlet-name>springDispatcherServlet</servlet-name>
		<url-pattern>*.action</url-pattern>
	</servlet-mapping>
  
  
</web-app>


最后在依赖中加入tomcat插件


<plugins>
      <!-- 加入Tomcat插件 -->
        <plugin>
          <groupId>org.apache.tomcat.maven</groupId>
          <artifactId>tomcat7-maven-plugin</artifactId>
          <version>2.2</version>
          		<configuration> 
          		    <url>http://localhost:8080/manager/text</url>
					<username>admin</username>  
					<password>admin</password>
				</configuration> 
        </plugin>
    </plugins>


然后右键项目-->Run AS --> Run Configurations ，在maven build的goals中输入命令: tomcat7:run





点击Run




然后访问: http://localhost:8080/fendo-SSM/index.jsp




点击添加





添加成功
