Eclipes基于maven的ssm框架整合

一、创建maven-webapp项目

 

二、更正环境，创建大纲

1、由于默认编译环境为jre1.5,现修复为jdk1.8

2、由于新建的maven工程不够标准，且版本过低，同样需做如下修改

 

3、补充完整的Maven目录

4、创建项目的大纲结构

这里并没有单独创建mapper包，我们把mapper文件也放在dao层

三、pom文件中导入jar包

          我把我pom文件整个都拷贝来了，有些初始化就有的东西你要去掉，保留你自己pom生成的那份。

四、创建实体类

package top.point9.entity;

public class User {
	private int id;
	private String username;
	private String password;
	public User() {
		super();
		// TODO Auto-generated constructor stub
	}
	public User(int id, String username, String password) {
		super();
		this.id = id;
		this.username = username;
		this.password = password;
	}
	@Override
	public String toString() {
		return "User [id=" + id + ", username=" + username + ", password=" + password + "]";
	}
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getUsername() {
		return username;
	}
	public void setUsername(String username) {
		this.username = username;
	}
	public String getPassword() {
		return password;
	}
	public void setPassword(String password) {
		this.password = password;
	}
}

五、创建数据库，IUserDao接口，IUserDao映射文件

1、先建数据库和数据表

2、在top.point9.top包下创建IUserDao接口

package top.point9.dao;

import top.point9.entity.User;

public interface IUserDao {

	public User getUserById(int id);
}

3、 在top.point9.top包下创建 IUserDao.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">
<!-- namespace命名空间，指向UserDao全路径 -->
<mapper namespace="top.point9.dao.IUserDao">

	<!-- 根据id查询用户信息 -->
	<!-- id：唯一标识 一个statement,和IUserDao方法名一致 #{}：表示 一个占位符，如果#{}中传入简单类型的参数，#{}中的名称随意 
		parameterType：输入 参数的类型，和IUserDao()里参数一致 resultType：输出结果 类型，和IUserDao()返回类型一致 -->
	<select id="getUserById" parameterType="int"
		resultType="top.point9.entity.User">
		select * from t_user where id =#{id}
	</select>
</mapper>

六、创建IUserService和UserServiceImpl

1、在top.point9.service包下创建IUserService接口

package top.point9.service;

import top.point9.entity.User;

public interface IUserService {
	public User getUserById(int id);
}

2、在top.point9.service.impl包下创建UserServiceImpl的实现类

package top.point9.service.impl;

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

import top.point9.dao.IUserDao;
import top.point9.entity.User;
import top.point9.service.IUserService;

@Service("userService")
public class UserServiceImpl implements IUserService {
	
	@Autowired
	private IUserDao userDao;
	
	@Override
	public User getUserById(int id) {
		return userDao.getUserById(id);
	}

}

七、创建JDBC文件和 log4j 日志文件

1、jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/maven?useUnicode=true&&characterEncoding=UTF-8
jdbc.username=root
jdbc.password=root

2、log4j.properties

log4j.rootLogger=INFO,Console,File  
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender  
log4j.appender.Console.Target=System.out  
# 可以灵活地自定日志的输出格式，下面一行是制定具体的输出格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout  
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n  
 
# 文件大小到达指定尺寸时，生成一个新文件
log4j.appender.File = org.apache.log4j.RollingFileAppender  
# 指定输出目录 
log4j.appender.File.File = logs/ssm.log  
# 定义文件最大空间 
log4j.appender.File.MaxFileSize = 10MB  
# 输出所有日志，如果换成DENUG，则表示输出DENUG以上级别的日志
log4j.appender.File.Threshold = ALL  
log4j.appender.File.layout = org.apache.log4j.PatternLayout  
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

八、设置spring、mybatis的配置文件

1、spring的配置文件applicationContext.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:aop="http://www.springframework.org/schema/aop" 
	xmlns:tx="http://www.springframework.org/schema/tx"
	xsi:schemaLocation="
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
 	http://www.springframework.org/schema/beans 
 	http://www.springframework.org/schema/beans/spring-beans-3.2.xsd 
 	http://www.springframework.org/schema/tx 
 	http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">

	<!-- 1.加载jdbc属性文件 -->
	<context:property-placeholder location="classpath:jdbc.properties"/>

	<!-- 开启包扫描 -->
	<context:component-scan base-package="top.point9"/>
	
	<!-- 2.创建数据源 -->
	<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
		<property name="jdbcUrl" value="${jdbc.url}"/>
		<property name="user" value="${jdbc.username}"/>
		<property name="password" value="${jdbc.password}"/>
		<property name="driverClass" value="${jdbc.driver}"/>
	</bean>
	
	<!-- 3.事务管理器 -->
	<bean id="tx" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
		<property name="dataSource" ref="dataSource"></property>
	</bean>
	
	<!-- 4.事务的策略 -->
	<tx:advice transaction-manager="tx" id="txAdvices">
		<tx:attributes>
			<!-- 读 -->
			<tx:method name="get*" isolation="DEFAULT" propagation="REQUIRED" read-only="true"/>
			<tx:method name="query*" isolation="DEFAULT" propagation="REQUIRED" read-only="true"/>
			
			<!-- 写 -->
			<tx:method name="add*" isolation="DEFAULT" propagation="REQUIRED" read-only="false"/>
			<tx:method name="update*" isolation="DEFAULT" propagation="REQUIRED" read-only="false"/>
			<tx:method name="delete*" isolation="DEFAULT" propagation="REQUIRED" read-only="false"/>
		</tx:attributes>
	</tx:advice>
	
	<!-- 5.AOP的控制(范围) -->
	<aop:config>
		<!-- 匹配的表达式 -->
		<aop:pointcut expression="execution( * top.point9.service.*.*(..))" id="p1"/>
		<aop:advisor advice-ref="txAdvices" pointcut-ref="p1"/>
	</aop:config>
	
	<!-- 6.MyBatis和Spring整合 -->
	<bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
		<!-- 数据源 -->
		<property name="dataSource" ref="dataSource"/>
		<!-- MyBatis的核心配置文件 -->
		<property name="configLocation" value="classpath:mybatis-config.xml"/>
		<!-- MyBatissql映射文件 -->
		<property name="mapperLocations" value="classpath:top/point9/dao/*.xml"/>
	</bean>
	
	<!-- 7.自动创建Dao层实现类 -->
	<bean id="daoProxy" class="org.mybatis.spring.mapper.MapperScannerConfigurer">
		<!-- sessionFactoryBean名称 -->
		<property name="sqlSessionFactoryBeanName" value="sessionFactory"/>
		<!-- dao层接口所在的包名 -->
		<property name="basePackage" value="top.point9.dao"></property>
	</bean>
</beans>

2、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>
<!-- 	<mappers> -->
<!-- 		<mapper resource="top/point9/dao/IUserMapper.xml" /> -->
<!-- 	</mappers> -->
</configuration>

九、建立测试类 TestInit.java

经过以上步骤（log4j不配也没影响），我们已经完成了Spring和mybatis的整合，这样我们就可以编写一段测试代码来试试是否成功了。

测试类在src/test/java中建立，如果测试成功，表示Spring和Mybatis已经整合成功了。输出信息使用的是Log4j打印到控制台。

package top.point9.test;

import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

import top.point9.entity.User;
import top.point9.service.IUserService;

/*让测试运行于Spring测试环境*/
@RunWith(SpringJUnit4ClassRunner.class) 

/*用来指定加载的Spring配置文件的位置,会加载默认配置文件*/
@ContextConfiguration(locations = { "classpath:applicationContext.xml" })
public class TestInit {
	@Autowired
    private IUserService userService;

    @Test
    public void test() {
        User user = userService.getUserById(1);
        System.out.println(user.toString());
    }
}

最后！关键看后台输出，也是见证奇迹的时候，如果输出对象那说明你配置整合成功！

十、整合springmvc并配置web.xml

1、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:aop="http://www.springframework.org/schema/aop" 
	xsi:schemaLocation="
	http://www.springframework.org/schema/aop 
	http://www.springframework.org/schema/aop/spring-aop-4.3.xsd
 	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-4.3.xsd">

	<!-- 开启包扫描 -->
	<context:component-scan base-package="top.point9.controller"/>
	
	<!-- 视图解析器 -->
	<bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
	    <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
	    <property name="prefix" value="/"/>
	    <property name="suffix" value=".jsp"/>
	</bean>
 </beans>

2、web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns="http://java.sun.com/xml/ns/javaee"
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
	id="WebApp_ID" version="2.5">
	<welcome-file-list>
		<welcome-file>index.jsp</welcome-file>
	</welcome-file-list>
	
	<!-- 1.乱码处理 -->
	<filter>
		<filter-name>CharacterEncodingFilter</filter-name>
		<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
	</filter>
	<filter-mapping>
		<filter-name>CharacterEncodingFilter</filter-name>
		<url-pattern>/*</url-pattern>
	</filter-mapping>
	
	<!-- 2.tomcat的启动的时候初始化Spring容器 -->
	<context-param>
		<param-name>contextConfigLocation</param-name>
		<param-value>classpath:applicationContext.xml</param-value>
	</context-param>
	<listener>
		<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
	</listener>
	
	<!-- 3.springmvc核心的配置 -->
	<servlet>
		<servlet-name>DispatcherServlet</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>
	
	<servlet-mapping>
		<servlet-name>DispatcherServlet</servlet-name>
		<url-pattern>/</url-pattern>
	</servlet-mapping>
</web-app>

十一、编写测试页面和controller前端控制器

1、text.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<% String path = request.getContextPath();
	String basePath = request.getScheme()+"://" +request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<base href="<%=basePath%>"/>
<meta charset="UTF-8">
<title>测试查询：</title>
</head>
<body>
<form action="user/getUser" method="post">
<label>ID：</label>
<input type="text" name="id"></input><br>
<input type="submit" value="查询"/>
</form>
</body>
</html>

2、控制器UserController

package top.point9.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;

import top.point9.dao.IUserDao;
import top.point9.entity.User;

@Controller
@RequestMapping("/user")
public class UserController {
	@Autowired
	private IUserDao userDao;
	
	@RequestMapping("/getUser")    
	public String getInfo(String id,ModelMap map){
	    User user =userDao.getUserById(Integer.parseInt(id));
	    //如果有学生就说明登录成功
	    if(user!=null){
	    	map.put("user", user);
	        return "susscss";
	    }
	    
	    return "err";
	}    
}

3、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"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<% String path = request.getContextPath();
	String basePath = request.getScheme()+"://" +request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<base href="<%=basePath%>"/>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
	${user} 
</body>
</html>

4、err.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>
<% String path = request.getContextPath();
	String basePath = request.getScheme()+"://" +request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE html>
<html>
<head>
<base href="<%=basePath%>"/>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
	<p>查询无果，稍后再试。</p>
</body>
</html>

十二、大功告成，截图如下：
