# 超级详细的SSM三大框架整合（基于springmvc+spring+mybatis构建项目） #

github地址：[SSM项目][SSM]

## 1.SSM是什么 ##

ssm：spring mvc + spring + mybaits

spring mvc 负责管理客户端与JAVA应用之间的交互（负责MVC设计模式）

mybatis 负责管理数据库与JAVA应用之间的交互（负责数据持久层）

spring则是负责管理spring mvc与mybatis相关对象的创建和依赖注入

## 2.基本步骤 ##

### 2.1创建maven工程，在pom.xml中添加相关的依赖 ###

创建项目

### 2.2配置web.xml来配置springmvc、spring、编码过滤器、放行静态资源 ###

web.xml

            <url-pattern>*.gif</url-pattern>
        </servlet-mapping>
        
    </web-app>

### 2.3配置spring.xml来整合mybatis ###

spring.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:util="http://www.springframework.org/schema/util" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" 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/util http://www.springframework.org/schema/util/spring-util.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">
    
        
        
        <context:property-placeholder location="classpath:jdbcConfig.properties"></context:property-placeholder>
        <bean name="druid" class="com.alibaba.druid.pool.DruidDataSource">

        </bean>
    
        
        <bean name="" class="org.mybatis.spring.SqlSessionFactoryBean">
            
            <property name="dataSource" ref="druid"></property>
            
            <property name="mapperLocations" value="classpath:com/hrbust/example/mapper/*.xml"></property>
            
            <property name="configLocation" value="classpath:mybatisConfig.xml"></property>

        </bean>
        
    
    
    </beans>

### 2.4配置mybatisCong.xml来配置一些其他设置 ###

<?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>
        <settings>
            <setting name="logImpl" value="LOG4J2"></setting>
            <setting name="lazyLoadingEnabled" value="true"/>
            <setting name="aggressiveLazyLoading" value="true"/>
        </settings>
    
    </configuration>

### 2.5配置springmvc.xml ###

springmvc.xml

### 2.6其他配置 ###

#### 2.6.1配置log4j2.xml来打印sql语句 ####

<?xml version="1.0" encoding="UTF-8"?>
    <Configuration status="WARN">
        <Appenders>
            <Console name="Console" target="SYSTEM_OUT">
                <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n"/>
            </Console>
        </Appenders>
        <Loggers>
            <Root level="DEBUG">
                <AppenderRef ref="Console"/>
            </Root>
            <logger name="java.sql" level="DEBUG"></logger>
            <logger name="org.apache.ibatis" level="INFO"></logger>
        </Loggers>
    </Configuration>

#### 2.6.2配置数据源 ####

jdbcConfig.properties

driverClassName=com.mysql.cj.jdbc.Driver
    url=jdbc:mysql://localhost:3306/数据库名?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC&allowPublicKeyRetrieval=true
    username=root
    password=root
    initialSize=5
    maxActive=10
    maxWait=3000
    minIdle=3
    validationQuery=SELECT 1
    testWhileIdle=true
    testOnBorrow=false
    testOnReturn=false

## 3.注意事项 ##

*  配置文件中的包名以及jdbcConfig.properties中的数据要与你的本地相关一致。
 *  具体的pojo、controller、service需要你自己去写。
 *  mapper.xml中的sql语句需要你自己写。
 *  SSM搭建完毕后，mapper接口的实现类已经在IOC容器中了，你只需要通过@Autowired获取即可。
