SSM搭建框架

1.使用maven创建项目：
SSM框架搭建整合

Groupid：项目的main下面Java的目录结构
Artifactid:项目的实际名称（根目录）
SSM框架搭建整合

2.创建完项目后创建好目录格式

4.所有的依赖导入之后开始进行整合

首先整合spring和mybatis
创建spring-bean.xml的spring核心文件
SSM框架搭建整合
创建完成后添加

时报错，原因是头部缺少：
xmlns:context=“http://www.springframework.org/schema/context”
添加后即可解决
创建jdbc.properties存放数据库配置文件

jdbc.driver=com.mysql.cj.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/javaexceptionone?useUnicode=true&characterEncoding=UTF-8&serverTimezone=GMT%2B8&useSSL=false
jdbc.username=root
jdbc.password=123456
filters=stat
initialSize=2
maxActive=300
maxWait=60000
timeBetweenEvictionRunsMillis=60000
minEvictableIdleTimeMillis=300000
validationQuery=SELECT 1
testWhileIdle=true
testOnBorrow=false
testOnReturn=false
poolPreparedStatements=false
maxPoolPreparedStatementPerConnectionSize=200

spring-bean最终效果：

<?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:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!-- 自动扫描 -->
    <context:component-scan base-package="com.study" />
    <!-- 引入配置文件 -->
    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties" />
    </bean>
    <!-- 配置数据源 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="filters" value="${filters}"/>
        <property name="initialSize" value="${initialSize}"/>
        <property name="maxActive" value="${maxActive}"/>
        <property name="maxWait" value="${maxWait}"/>
        <property name="timeBetweenEvictionRunsMillis" value="${timeBetweenEvictionRunsMillis}"/>
        <property name="minEvictableIdleTimeMillis" value="${minEvictableIdleTimeMillis}"/>
        <property name="poolPreparedStatements" value="${poolPreparedStatements}"/>
        <property name="maxPoolPreparedStatementPerConnectionSize" value="${maxPoolPreparedStatementPerConnectionSize}"/>
        <property name="validationQuery" value="${validationQuery}"/>
        <property name="testWhileIdle" value="${testWhileIdle}"/>
        <property name="testOnBorrow" value="${testOnBorrow}"/>
        <property name="testOnReturn" value="${testOnReturn}"/>
    </bean>

    <!-- 事务管理器 完成手动事务管理-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <constructor-arg name="dataSource" ref="dataSource" />
    </bean>
    <!-- 配置mybatis-->
    <!--sqlsessionFactory 管理连接池-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 自动扫描mapper.xml文件(当mapper.xml文件在resources下面时才需要使用到这个)-->
        <!--        <property name="mapperLocations" value="classpath:mapper/*.xml"/>-->
        <!-- 载入mybatis全局配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
    <!-- 配置mybatis dao接口扫描-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="ssm.study.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>
    <!--  扫描包里面的mapper.xml文件，这个方法和上面的方法一致 -->
    <!--    <mybatis:scan base-package="ssm.study.dao"/>-->
    <!-- 开启事务控制的注解支持 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

<tx:annotation-driven transaction-manager=“transactionManager”/>

会报错，原因是头部缺少

xmlns:tx=“http://www.springframework.org/schema/tx”

我们还得创建mybatis-config.xml文件
这个文件主要配置mybatis全局配置文件
例如别名驼峰命名自动转换等在这里我暂时只配置别名

<?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>
    <!--别名-->
    <typeAliases>
        <package name="ssm.study.entity"/>
    </typeAliases>

</configuration>

整合完成

5.接下来整合springmvc和spring

创建spring-mvc.xml文件

<?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: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/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!-- 扫描所有com.study.controller包下面的所有controller -->
    <context:component-scan base-package="com.study.controller"/>
    <!-- 开启注解配置-->
    <mvc:annotation-driven/>
    <!-- 静态资源解析，包括js,css,img... -->
    <mvc:default-servlet-handler/>

    <!-- 配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--视图前缀-->
        <property name="prefix" value="/"/>
        <!--视图后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

最后配置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_3_0.xsd"
         id="WebApp_ID" version="3.0">

  <welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
  </welcome-file-list>
  <!--spring配置文件路径-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring-bean.xml</param-value>
  </context-param>
  <!-- 配置spring监听器-->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <!--spring mvc核心servlet-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 初始化参数配置 springnvc配置文件路径-->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
    <async-supported>true</async-supported>
  </servlet>
<!--  拦截器的配置-->
  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
  <!--  <servlet-mapping>-->
  <!--    <servlet-name>dispatcherServlet</servlet-name>-->
  <!--    <url-pattern>*.html</url-pattern>-->
  <!--  </servlet-mapping>-->
  <!-- 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>
  <!-- log4j日志配置 -->
  <context-param>
    <param-name>log4jConfigLocation</param-name>
    <param-value>classpath:log4j.properties</param-value>
  </context-param>
  <listener>
    <description>log4j配置加载器</description>
    <listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
  </listener>
</web-app>

创建log4j.properties

log4j.rootLogger=WARN, console
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%5p [%t] (%F:%L) - %m%n

此时已经整合完毕，但是仍然无法运行
原因是spring-bean头部文件不对，更改后的头部文件

<?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:mybatis="http://mybatis.org/schema/mybatis-spring" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">

所以spring-bean文件最后为：

<?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:mybatis="http://mybatis.org/schema/mybatis-spring" xmlns:tx="http://www.springframework.org/schema/tx"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://mybatis.org/schema/mybatis-spring http://mybatis.org/schema/mybatis-spring.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">

    <!-- 自动扫描 -->
    <context:component-scan base-package="com.study" />
    <!-- 引入配置文件 -->
    <bean id="propertyConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="location" value="classpath:jdbc.properties" />
    </bean>
    <!-- 配置数据源 -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
        <property name="filters" value="${filters}"/>
        <property name="initialSize" value="${initialSize}"/>
        <property name="maxActive" value="${maxActive}"/>
        <property name="maxWait" value="${maxWait}"/>
        <property name="timeBetweenEvictionRunsMillis" value="${timeBetweenEvictionRunsMillis}"/>
        <property name="minEvictableIdleTimeMillis" value="${minEvictableIdleTimeMillis}"/>
        <property name="poolPreparedStatements" value="${poolPreparedStatements}"/>
        <property name="maxPoolPreparedStatementPerConnectionSize" value="${maxPoolPreparedStatementPerConnectionSize}"/>
        <property name="validationQuery" value="${validationQuery}"/>
        <property name="testWhileIdle" value="${testWhileIdle}"/>
        <property name="testOnBorrow" value="${testOnBorrow}"/>
        <property name="testOnReturn" value="${testOnReturn}"/>
    </bean>

    <!-- 事务管理器 完成手动事务管理-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <constructor-arg name="dataSource" ref="dataSource" />
    </bean>
    <!-- 配置mybatis-->
    <!--sqlsessionFactory 管理连接池-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 自动扫描mapper.xml文件(当mapper.xml文件在resources下面时才需要使用到这个)-->
        <!--        <property name="mapperLocations" value="classpath:mapper/*.xml"/>-->
        <!-- 载入mybatis全局配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
    </bean>
    <!-- 配置mybatis dao接口扫描-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.study.dao"/>
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>
    <!--  扫描包里面的mapper.xml文件，这个方法和上面的方法一致 -->
    <!--    <mybatis:scan base-package="ssm.study.dao"/>-->
    <!-- 开启事务控制的注解支持 -->
    <tx:annotation-driven transaction-manager="transactionManager"/>
</beans>

SSM框架整合完成！
注意：
如果没有使用注解将会运行不了，因为spring扫描不到bean
还一个关键点就是整合后的ssm如果我们将mapper.xml文件和mapper接口放在一起时，将会扫描不到，因为mapper.xml是resource文件，这时我们需要在pom的built上添加

<!--    用来解决mapper.xml与mapper.java放在一起不编译的问题-->
<resources>
  <resource>
    <directory>src/main/java</directory>
    <includes>
      <include>**/*.xml</include>
    </includes>
  </resource>
</resources>

使其变成源文件可以扫描到，整合完成！
