SSM环境的搭建

虽然如今流行SpringBoot了，可是对于之前的SSM配置地狱的框架搭建整合作一个简单的Demo前端

首先建立新的项目，选择Maven管理咱们的依赖如图所示：java

固然我是为了作列子，因此采用的中文，mysql

而后选择本身的maven地址，这里稍微注意的是，Maven默认读取的是 .m2/setting.xml做为配置文件，web

　　我改动了配置文件的相关下载和配置文件存储路径，因此我选用我本身的配置文件做为启动配置spring

而后等待下载，下载完以后，项目构建以下：sql

而后建立java 文件夹，做为咱们存放代码的文件，并在下面建立出响应的 package 模块数据库

最后就是这样的apache

——————————前期的基本准备工做到此为止，下面开始搭建环境————————————api

先把最后的样子贴出来，能够先把结构搭起来，再填充内容：spring-mvc

1:优先配置 maven的 pom.xml 导入相关依赖

120       </configuration>
121     </plugin>
122   </plugins>
123 </build>

而后配置web.xml

 <!-- 配置监听器加载spring -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!-- 配置SpringBeans的配置文件所在目录-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/applicationContext.xml</param-value>
  </context-param>

  <!-- 配置 SpringMVC前端控制器 -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <!-- 修改默认springmvc加载的配置文件路径 -->
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring/springmvc.xml</param-value>
    </init-param>
    <!-- 配置Spring的启动时机 >=0随着容器一块儿启动  <0第一次来请求时启动 -->
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- 配置编码方式-->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <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> 　　<!--设置一个默认访问的页面--> <welcome-file-list> <welcome-file>/WEB-INF/index.jsp</welcome-file> </welcome-file-list>

web.xml中指定的文件，咱们循序渐进的造出来

依次为：applicationContext.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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context-3.2.xsd
        http://www.springframework.org/schema/aop
        http://www.springframework.org/schema/aop/spring-aop-3.2.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx-3.2.xsd">

    <!-- 配置注解扫描 -->
    <context:component-scan base-package="com.test.ssm.service" />

    <!-- 加载数据源所须要的参数配置文件 -->
    <context:property-placeholder location="classpath:jdbc.properties"/>

    <!-- 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}" />
    </bean>

    <!-- 让Spring管理myBatis的会话工厂 SqlsessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean" >
       <!--注入数据库链接池-->
        <property name="dataSource" ref="dataSource"/>
        <!--扫描Model包，使用别名-->
        <property name="typeAliasesPackage" value="com.test.ssm.model"/>
        <!-- 扫描sql配置文件： mapper须要的xml文件 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
    </bean>

    <!-- 配置扫描Dao接口包，动态实现Dao接口，注入到spring容器中 -->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入Dao-->
        <property name="basePackage" value="com.test.ssm.dao"/>
        <!--注入sqlSession工厂-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
    </bean>

    <!--配置事务管理器-->
    <bean id="trancationManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--开启声明式事务-->
    <tx:annotation-driven transaction-manager="trancationManager"/>
</beans>

其次：springmvc.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <beans xmlns="http://www.springframework.org/schema/beans"
 3        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
 4        xmlns:context="http://www.springframework.org/schema/context"
 5        xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx"
 6        xsi:schemaLocation="http://www.springframework.org/schema/beans
 7       http://www.springframework.org/schema/beans/spring-beans-3.2.xsd
 8       http://www.springframework.org/schema/mvc
 9       http://www.springframework.org/schema/mvc/spring-mvc-3.2.xsd
10       http://www.springframework.org/schema/context
11       http://www.springframework.org/schema/context/spring-context-3.2.xsd">
12 
13     <!-- 1.配置注解扫描位置 -->
14     <context:component-scan base-package="com.test.ssm.controller" />
15 
16     <!-- 2.配置注解处理映射 3.配置适配器-->
17     <mvc:annotation-driven />
18 
19     <!-- 4.配置springmvc视图解析器 视图解析器解析的视频路径为：前缀 + 后缀 -->
20     <bean 21             class="org.springframework.web.servlet.view.InternalResourceViewResolver">
22         <property name="prefix" value="/WEB-INF/views" />
23         <property name="suffix" value=".jsp" />
24     </bean>
25 </beans>

而后 applicationContext.xml 又依赖新的配置文件，逐一配置出来

jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8
jdbc.username=root
jdbc.password=root

logback.xml

 1 <?xml version="1.0" encoding="UTF-8"?>
 2 <configuration debug="true">
 3     <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
 4         <encoder>
 5             <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
 6         </encoder>
 7     </appender>
 8     <root level="INFO">
 9         <appender-ref ref="STDOUT"/>
10     </root>
11 </configuration>

运行服务器，看看效果

自动跳转到了默认的index.jsp

测试一下数据库，查询一点数据看看可否连通

发现本身都不太熟悉了，但愿之后再也用不上！
