基于maven的ssm框架整合

 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。

</project>

  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">

        </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-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！
