SSM（spring mvc+spring+Mybatis）框架整合

栏目：框架设计时间：2016-06-03 08:13:18

最近用Idea开发，idea是1款综合的相对较新的Java IDE。Idea支持很多整合功能，我觉得挺好用的。Idea可以校订xml，支持jsp的调试。最使我喜欢的是，写spring配置文件的时候，写的1些路径都可以自己找到。classpath自己有代码的提示，超级的智能。

环境配置

在整合框架之前，先配置1下JER运行环境，配置maven仓库。
1.File——ProjectStructure——Project——New… 选择jdk的安装环境
选择sdk的安装路径

2.File——Settings——Maven——Maven home directory选择自己maven的安装目录。下面是maven管理jar包的地方。

概念

1.spring

Spring目的：就是让对象与对象（模块与模块）之间的关系没有通过代码来关联，都是通过配置类说明管理的，简单的说，不用在代码里写死new某个对象，而是全部在配置文件中进行了配置。Spring是1个容器，凡是在容器里的对象才会有Spring所提供的这些服务和功能。

2.Spring MVC

Spring MVC属于SpringFrameWork的后续产品，已融会在Spring Web Flow里面。Spring MVC 分离了控制器、模型对象、分派器和处理程序对象的角色，这类分离让它们更容易进行定制。

3.Mybatis

MyBatis 是支持普通 SQL查询，存储进程和高级映照的优秀持久层框架。MyBatis 消除几近所有的JDBC代码和参数的手工设置和结果集的检索。MyBatis 使用简单的 XML或注解用于配置和原始映照，将接口和 Java 的POJOs（Plain Old Java Objects，普通的 Java对象）映照成数据库中的记录。

spring Mybatis整合

用的框架的版本分别是：
spring版本号 4.0.2.RELEASE
mybatis版本号 3.2.6
Spring MVC版本号 4.0.2 RELEASE
log4j日志文件管理包版本号 {slf4j |1.7.7} { log4j |1.2.17}

项目目录以下：

2.建立jdbc.properties，配置数据库信息

driver=com.mysql.jdbc.Driver
url=jdbc:mysql:///ordersystem
username=root
password=123456
#定义初始连接数
initialSize=0
#定义最大连接数
maxActive=20
#定义最大空闲
maxIdle=20
#定义最小空闲
minIdle=1
#定义最长等待时间
maxWait=60000

3.log4j.properties配置文件

#定义LOG输出级别
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1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1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

4.建立spring-Mybatis.xml配置文件

<?xml version="1.0" encoding="UTF⑻"?>
<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-beans⑶.1.xsd
                        http://www.springframework.org/schema/context
                        http://www.springframework.org/schema/context/spring-context⑶.1.xsd
                        http://www.springframework.org/schema/mvc
                        http://www.springframework.org/schema/mvc/spring-mvc⑷.0.xsd">
    <!-- 自动扫描 -->
    <context:component-scan base-package="com.cn.order" />
    <!-- 引入配置文件 -->
    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties" />
    </bean>

    <bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
          destroy-method="close">
        <property name="driverClassName" value="${driver}" />
        <property name="url" value="${url}" />
        <property name="username" value="${username}" />
        <property name="password" value="${password}" />
        <!-- 初始化连接大小 -->
        <property name="initialSize" value="${initialSize}"></property>
        <!-- 连接池最大数量 -->
        <property name="maxActive" value="${maxActive}"></property>
        <!-- 连接池最大空闲 -->
        <property name="maxIdle" value="${maxIdle}"></property>
        <!-- 连接池最小空闲 -->
        <property name="minIdle" value="${minIdle}"></property>
        <!-- 获得连接最大等待时间 -->
        <property name="maxWait" value="${maxWait}"></property>
    </bean>

    <!-- spring和MyBatis完善整合，不需要mybatis的配置映照文件 -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <!-- 自动扫描mapping.xml文件 -->
        <property name="mapperLocations" value="classpath:com/cn/order/mapping/*.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.cn.order.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>

5.服务层接口 service

package com.cn.order.service;

import com.cn.order.pojo.User;
/**
 * Created by azz-pc on 2016/5/24.
 */
public interface IUserService {
    User getUserById(int userId);
}

6.服务层实现serviceImpl

package com.cn.order.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;

import com.cn.order.dao.IUserDao;
import com.cn.order.pojo.User;
import com.cn.order.service.IUserService;

/**
 * Created by azz-pc on 2016/5/24.
 */
@Service("userService")
public class UserServiceImpl implements IUserService {
    @Resource 
    private IUserDao userDao;

    public User getUserById(int userId) {

        return this.userDao.selectByPrimaryKey(userId);
    }

}

7.Junit测试
测试类编写：

package org.zsl.testmybatis;

import javax.annotation.Resource;

import com.cn.order.pojo.*;
import com.cn.order.service.*;
import org.apache.log4j.Logger;
/*import org.apache.log4j.net.SyslogAppender;*/
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.context.ApplicationContext;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;



@RunWith(SpringJUnit4ClassRunner.class)     //表示继承了SpringJUnit4ClassRunner类
@ContextConfiguration(locations = {"classpath:spring-mybatis.xml"})
public class TestMyBatis {
    private static Logger logger = Logger.getLogger(TestMyBatis.class);
    private ApplicationContext ac = null;
    @Resource
    //private IUserService userService = null;
    private ICardService cardService=null;

    private Card card=new Card();
//  @Before
//  public void before() {
//      ac = new ClassPathXmlApplicationContext("applicationContext.xml");
//      userService = (IUserService) ac.getBean("userService");
//  }

    @Test
    public void test1() {
//        User user = userService.getUserById(1);
//        System.out.println(user.getUsername());
//        System.out.println(user.getPassword());
//        System.out.println(user.getState());
//        logger.info("值："+user.getUsername());
//        logger.info(JSON.toJSONString(user));

        card.setCardid("E000010");
        card.setPassword("33333");
        card.setOwnername("xiaozhou");
        card.setCash("10.0");
        card.setCardtypeid(1);
        card.setStatus("T");
        cardService.insert(card);
        System.out.println("insert success");

    }
}

利用MyBatis Generator自动创建mapping，dao，pojo层，详情参见博客：http://blog.csdn.net/zhou2s_101216/article/details/51175818

这里写图片描述

输出insert success 证明测试成功。

整合springMVC

1.配置spring-mvc.xml

<?xml version="1.0" encoding="UTF⑻"?>
<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-beans⑶.1.xsd

                        http://www.springframework.org/schema/context/spring-context⑶.1.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.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.cn.order.controller"/>

    <!--<mvc:default-servlet-handler/>-->

    <!--避免IE履行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=UTF⑻</value>
            </list>
        </property>
    </bean>
    <!-- 启动SpringMVC的注解功能，完成要求和注解POJO的映照 -->
    <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1个 可用的url地址 -->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

    <bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <!-- 默许编码 -->
        <property name="defaultEncoding" value="utf⑻"/>
        <!-- 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>

    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties"/>
    </bean>

</beans>

2.配置web.xml

<?xml version="1.0" encoding="UTF⑻"?>
<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">

  <!-- 编码过滤器 -->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>

    <init-param>
      <param-name>encoding</param-name>
      <param-value>UTF⑻</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>
  <!-- 避免Spring内存溢出监听器 -->
  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>

  <!-- Spring MVC servlet -->

      <param-value>classpath:spring-mvc.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>
  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.css</url-pattern>
  </servlet-mapping>

  <servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
  </welcome-file-list>
  <!-- 配置SESSION超时，单位是分钟 -->
  <session-config>
    <session-timeout>15</session-timeout>
  </session-config>

</web-app>

3.前台使用的是，spring mvc、bootstrap、angularjs
showUser.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf⑻" %>
