基于maven的ssm框架整合
第一步：通过maven建立一个web项目。
第二步：pom文件导入jar包
(1) pom.xml
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。

第三步：看整体的项目架构，先说明下我这里还没有有关springMVC的相关东西，因为我先整合sping-mybatis,在测试是否成功，成功在整合springMVC
第四步：建立model类
public class User {
private int id;
private String name;
private String password;
private String password2;
/*提供set和get方法，toString方法*/
}
第五步：创建数据库,UserDao接口和mapper映射文件
（1）建立很简单的一张表
（2）UserDao接口
public interface UserDao {
User findUserById(User user);
}
（3）UesrMapper.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="com.ssm.dao.UserDao"> <!-- 根据id查询用户信息 -->
<!--
id：唯一标识 一个statement,和UserDao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UserDao()里参数一致
resultType：输出结果 类型，和UserDao()返回类型一致
-->
<select id="findUserById" parameterType="com.ssm.model.User" resultType="com.ssm.model.User">
SELECT * FROM USER
<where>
<if test="name != null">
AND Name= #{name}
</if>
<if test="password != null">
AND password= #{password}
</if>
</where>
</select>
</mapper>
第五步：创建UserService和UserServiceImpl
（1）UserService
public interface UserService {
public User getUserById(User user);
}
（2）UserServiceImpl
import org.springframework.stereotype.Service; import com.ssm.dao.UserDao;
import com.ssm.model.User;
import com.ssm.service.UserService; @Service("userService")
public class UserServerImpl implements UserService { @Resource
private UserDao userDao; public User getUserById(User user) { return this.userDao.findUserById(user);
} }
第六步：创建jdbc文件和log日志文件
（1）jdbc.properties
jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://localhost\:3306/test?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
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
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的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
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
第七步：整合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:mvc="http://www.springframework.org/schema/mvc"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描 -->
<context:component-scan base-package="com.ssm" />
<!-- 引入实现jdbc配置文件 -->
<bean id="propertyConfigurer"
class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="location" value="classpath:jdbc.properties" />
</bean> <!-- 2.数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
</bean> <!-- spring和MyBatis整合，通过spring来管理MyBatis的SqlSessionFactory会话工厂 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 指定数据库连接池引用 -->
<property name="dataSource" ref="dataSource" />
<!-- 自动扫描mapping.xml文件 -->
<property name="mapperLocations" value="classpath:com/ssm/mapper/*.xml"></property>
</bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.ssm.dao" />
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>
</bean> <!-- (事务管理)transaction manager, use JtaTransactionManager for global tx -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>
第八步：建立测试类
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。
（1）TestMyBatis测试类
package ssm; import javax.annotation.Resource; import org.apache.log4j.Logger;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner; import com.ssm.model.User;
import com.ssm.service.UserService; /*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:spring-mybatis.xml" }) public class TestMyBatis { @Resource(name = "userService")
private UserService userService; @Test
public void test1() {
User user=new User();
user.setName("张三");
user.setPassword("123");
User user1 = userService.getUserById(user);
System.out.println(user1.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！
那接下来我们开始整合springMVC
第九步：配置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:p="http://www.springframework.org/schema/p"
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-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">
<!-- 自动扫描该包，使SpringMVC认为包下用了@controller注解的类是控制器 -->
<context:component-scan base-package="com.ssm.controller" />
<!--避免IE执行AJAX时，返回JSON出现下载文件 -->
<bean id="mappingJacksonHttpMessageConverter"
class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter">
<property name="supportedMediaTypes">
<list>
<value>text/html;charset=UTF-8</value>
</list>
</property>
</bean>
<!-- 启动SpringMVC的注解功能，完成请求和注解POJO的映射 -->
<bean
class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
<property name="messageConverters">
<list>
<ref bean="mappingJacksonHttpMessageConverter" /> <!-- JSON转换器 -->
</list>
</property>
</bean>
<!-- 定义跳转的文件的前后缀 ，视图模式配置-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 这里的配置我的理解是自动给后面action的方法return的字符串加上前缀和后缀，变成一个 可用的url地址 -->
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean> <!-- 配置文件上传，如果没有使用文件上传可以不用配置，当然如果不配，那么配置文件中也不必引入上传组件包 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 默认编码 -->
<property name="defaultEncoding" value="utf-8" />
<!-- 文件大小最大值 -->
<property name="maxUploadSize" value="10485760000" />
<!-- 内存中的最大值 -->
<property name="maxInMemorySize" value="40960" />
</bean> </beans>
第十步：配置web.xml文件
这里面对spring-mybatis.xml的引入以及配置的spring-mvc的Servlet就是为了完成SSM整合，之前2框架整合不需要在此处进行任何配置。
<?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_3_0.xsd"
version="3.0">
<display-name>Archetype Created Web Application</display-name>
<!-- Spring和mybatis的配置文件 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:spring-mybatis.xml</param-value>
</context-param>
<!-- 编码过滤器 -->
<filter>
<filter-name>encodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<async-supported>true</async-supported>
<init-param>
<param-name>encoding</param-name>
<param-value>UTF-8</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>encodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<!-- Spring监听器 -->
<listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
<!-- 防止Spring内存溢出监听器 -->
<listener>
<listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
</listener> <!-- Spring MVC servlet -->
<servlet>
<servlet-name>SpringMVC</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>
<async-supported>true</async-supported>
</servlet>
<servlet-mapping>
<servlet-name>SpringMVC</servlet-name>
<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>/</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list> </web-app>
第十一步最后测试：
(1) 先写login.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html>
<head>
<title>用户登录：</title>
</head>
<body>
<form action="login">
<label>用户名：</label>
<input type="text" id="username" name="username"></input><br><br>
<label>密码：</label>
<input type="text" id="password" name="password"></input><br><br>
<input type="submit" value="登录"/>
</form>
</body>
</html>
界面：
(2)在写UserController
import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping; import com.ssm.dao.UserDao;
import com.ssm.model.User; @Controller
public class UserController { @Resource
private UserDao userDao; @RequestMapping("/jsp/login")
public String login(HttpServletRequest request){
String username=request.getParameter("username");
String password=request.getParameter("password"); User user=new User();
//根据用户名和学生查询数据库
user.setName(username);
user.setPassword(password); User users=userDao.findUserById(user);
//如果有学生就说明登录成功
if(users!=null){
return "susscss";
}
//这个jsp我没有写，大家知道就好，你们可以自己写
return "err";
}
}
(3)最后susscss.jsp
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<html> <body>
<P>用户账号密码正确，登录成功</P>
</body>
</html>
完美！
水滴石穿，成功的速度一定要超过父母老去的速度！ 少尉【6】
