SSM框架搭建过程

前言

自己老是忘记框架搭建的基本设置，这次记下笔记。注：本人用的IDEA 2016。

搭建步骤

一、创建Maven项目

具体步骤如下图：

先NEW一个project。

二、导入相关的jar包

pom.xml相关设置

先设置各种jar包的版本号

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    <maven.compiler.source>1.7</maven.compiler.source>
    <maven.compiler.target>1.7</maven.compiler.target>
    <spring.version>4.0.2.RELEASE</spring.version>
    <mybatis.version>3.2.6</mybatis.version>
    <slf4j.version>1.7.7</slf4j.version>
    <log4j.version>1.2.15</log4j.version>
  </properties>

然和导入spring相关的核心包

<dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>

    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-oxm</artifactId>

      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
      <scope>test</scope>
    </dependency>

再导入mybais的相关包

<!-- mybatis 核心包 -->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis</artifactId>
      <version>${mybatis.version}</version>
    </dependency>
    <!-- spring 整合mybatis -->
    <dependency>
      <groupId>org.mybatis</groupId>
      <artifactId>mybatis-spring</artifactId>
      <version>1.2.2</version>
    </dependency>

最后导入其他的工具包

<dependency>
      <groupId>javax</groupId>
      <artifactId>javaee-api</artifactId>
      <version>7.0</version>
    </dependency>

    </dependency>
    <dependency>
      <groupId>com.github.pagehelper</groupId>
      <artifactId>pagehelper</artifactId>
      <version>5.1.0</version>
    </dependency>
    <!-- JSTL标签库 -->
    <dependency>
      <groupId>jstl</groupId>
      <artifactId>jstl</artifactId>
      <version>1.2</version>
    </dependency>
    <!-- 日志管理文件 -->
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>${log4j.version}</version>
    </dependency>
    <dependency>
      <groupId>com.alibaba</groupId>
      <artifactId>fastjson</artifactId>
      <version>1.1.41</version>
    </dependency>
    <dependency>
      <groupId>log4j</groupId>
      <artifactId>log4j</artifactId>
      <version>1.2.17</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
      <version>1.7.21</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-api</artifactId>
      <version>1.7.21</version>
    </dependency>
    <dependency>
      <groupId>org.slf4j</groupId>
      <artifactId>slf4j-log4j12</artifactId>
      <version>1.7.21</version>
    </dependency>
    <dependency>
      <groupId>org.codehaus.jackson</groupId>
      <artifactId>jackson-mapper-asl</artifactId>
      <version>1.9.13</version>
    </dependency>
    <!-- 上传组件相关包 -->
    <dependency>
      <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
      <version>1.3.1</version>
    </dependency>
    <dependency>
      <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
      <version>2.4</version>
    </dependency>
    <dependency>
      <groupId>commons-codec</groupId>
      <artifactId>commons-codec</artifactId>
      <version>1.9</version>
    </dependency>

三、书写ApplicationContext.xml（spring的配置文件）

首先去扫描包

<context:component-scan base-package="com.ssm.song.service"/>

然后去配置数据源

<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
        <property name="driverClass" value="com.mysql.jdbc.Driver"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssmdemo"/>
        <property name="user" value="root"/>
        <property name="password" value="song2"/>
    </bean>

和mybatis的整合（注入sqlSessionFactory）

<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 注入数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <!-- 指出mapper.xml 文件路径 -->
        <property name="mapperLocations" value="classpath:mapper/*.xml"/>
        <!-- 别名的包 -->
        <property name="typeAliasesPackage" value="com.ssm.song.bean"/>
</bean>

配置Mapper扫描器和事务管理器

<bean class="tk.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="sqlSessionFactoryBeanName" value="SqlSessionFactory"/>
        <property name="basePackage" value="com.ssm.song.dao"/>
    </bean>
    <!-- 配置事务管理器 -->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>

最后开启注解事务

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

四、书写spring-mvc.xml（springMVC的配置文件）

<!-- 配置扫描的包 -->
    <!-- spring mvc 只需扫描 controller -->
    <context:component-scan base-package="com.ssm.song.controller"/>
    <!-- 配置注解驱动 -->
    <mvc:annotation-driven/>
    <!-- 配置静态资源访问：js，css等 -->
    <mvc:resources mapping="/static/" location="/static/**"/>
    <!-- 配置视图解析器 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="suffix" value=".jsp"/>
        <property name="prefix" value="/WEB-INF/views/"/>
    </bean>

五、书写web.xml

主要是将spring和springMVC的配置文件加入web.xml中

集成spring：

<!-- 集成 spring 配置文件 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>
  <!-- web容器启动完成之后，立即初始化spring容器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

集成springMVC：

<!-- 配置Spring MVC 前端控制器 -->
  <servlet>
    <servlet-name>SpringMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 指定SpringMVC的配置文件 -->
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:spring-mvc.xml</param-value>
    </init-param>
  </servlet>
  <servlet-mapping>
    <servlet-name>SpringMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

在这加上一个编码过滤器防止乱码：

<!-- 配置编码过滤器 ： 来自spring-web 包-->
  <filter>
    <filter-name>CharacterEncodingFilter</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>
    <init-param>
      <param-name>forceEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>
