在IDEA中搭建基于Maven的SSM框架（二）

一步一步的教你在IDEA中搭建SSM框架

开发环境：JDK1.8、MySQL、Maven3.6

开发工具：IDEA 2018.3.1

在IDEA中搭建基于Maven的SSM框架（一）中已经介绍了在IDEA中搭建基于Maven的web项目

现在正式开始搭建我们的SSM框架，GO！

一、Spring整合SpringMVC

1.在pom.xml中导入spring、springMVC的Maven依赖

  <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版本号 -->
    <spring.version>5.1.4.RELEASE</spring.version>
    <jackson.version>2.9.8</jackson.version>
  </properties>

  <dependencies>

    <!-- Spring核心包 -->
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-core</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-web</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-oxm</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-tx</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-jdbc</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-webmvc</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-aop</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-context-support</artifactId>
      <version>${spring.version}</version>
    </dependency>
    <dependency>
      <groupId>org.springframework</groupId>
      <artifactId>spring-test</artifactId>
      <version>${spring.version}</version>
    </dependency>

    <!-- jackson:Json数据转换 -->
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-core</artifactId>
      <version>${jackson.version}</version>
    </dependency>
    <dependency>
      <groupId>com.fasterxml.jackson.core</groupId>
      <artifactId>jackson-databind</artifactId>
      <version>${jackson.version}</version>
    </dependency>    

    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

2.在src/main/java下创建包com.demo（项目创建时的GroupId）

3.在src/main/resources中新建spring文件夹存放spring、springMVC相关配置

在spring文件夹下创建applicationContext.xml、spring-mvc.xml

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

spring-mvc.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:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
                           http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
                           http://www.springframework.org/schema/context
                           http://www.springframework.org/schema/context/spring-context-4.0.xsd
                           http://www.springframework.org/schema/mvc
                           http://www.springframework.org/schema/mvc/spring-mvc-4.0.xsd">

    <!-- 注解驱动 -->
    <mvc:annotation-driven>
        <!-- 使用driven可忽略此配置 -->
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <constructor-arg index="0" value="UTF-8"/>
            </bean>
            <!-- json格式的转换器(json格式化) -->
            <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
                <property name="prettyPrint" value="true"/>
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

    <!-- 注解扫描 -->
    <context:component-scan base-package="com.demo"/>

    <!--视图解析器-->
    <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <property name="suffix" value=".jsp"/>
    </bean>

</beans>

4.配置web.xml

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >

<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee
                             http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">

  <display-name>ssm</display-name>

  <!-- web默认页面 -->
  <welcome-file-list>
    <welcome-file>/index.jsp</welcome-file>
  </welcome-file-list>

  <!-- Spring配置 -->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:spring/applicationContext.xml</param-value>
  </context-param>
  <!-- 内存泄漏监听器（建议放在首位） -->
  <listener>
    <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class>
  </listener>
  <!-- Spring监听器 -->
  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>
  <listener>
    <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class>
  </listener>


  <!-- springMVC配置 -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <init-param>
      <param-name>contextConfigLocation</param-name>
      <!--springMVC的配置路径 -->
      <param-value>classpath:spring/spring-mvc.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <!-- 拦截设置 -->
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!-- session超时配置 -->
  <session-config>
    <session-timeout>30</session-timeout>
  </session-config>

  <!-- 字符编码过滤器 -->
  <filter>
    <filter-name>encodingFilter</filter-name>
    <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
    <init-param>
      <param-name>encoding</param-name>
      <param-value>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>encodingFilter</filter-name>
    <url-pattern>*.do</url-pattern>
  </filter-mapping>

</web-app>

5.加入maven-generator插件

在pom.xml的build节点下添加：

注意：一定要与pluginManagement节点同级放置！！！

    <!-- mybatis generator 自动生成代码插件 与pluginManagement同级别-->
    <plugins>
      <plugin>
        <groupId>org.mybatis.generator</groupId>
        <artifactId>mybatis-generator-maven-plugin</artifactId>
        <version>1.3.2</version>
        <configuration>
          <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile>
          <overwrite>true</overwrite>
          <verbose>true</verbose>
        </configuration>
      </plugin>
    </plugins>

在src/main/resources下添加generatorConfig.xml配置文件

注意：数据库驱动存放位置

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <!-- 数据库驱动:选择你的本地硬盘上面的数据库驱动包-->
    <classPathEntry  location="F:\maven-repository\mysql\mysql-connector-java\8.0.13\mysql-connector-java-8.0.13.jar"/>

    <context id="DB2Tables"  targetRuntime="MyBatis3">

        <!-- 注释生成器 -->
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!--数据库驱动、URL，用户名、密码 -->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1.:3306/springboot"
                        userId="root"
                        password="root">
        </jdbcConnection>

        <!-- mybatis处理NUMERIC和DECIMAL类型的策略 -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false"/>
        </javaTypeResolver>

        <!-- 生成模型的包名和位置-->
        <javaModelGenerator targetPackage="com.demo.model" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- 生成映射文件的包名和位置-->
        <sqlMapGenerator targetPackage="mapping"
                         targetProject="src/main/resources">
            <property name="enableSubPackages" value="true"/>
        </sqlMapGenerator>

        <!-- 生成DAO的包名和位置-->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.demo.mapper"
                             targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
        <!-- 禁用Example -->
        <!--<table tableName="system_role"-->
               <!--domainObjectName="SystemRole"-->
               <!--enableCountByExample="false"-->
               <!--enableUpdateByExample="false"-->
               <!--enableDeleteByExample="false"-->
               <!--enableSelectByExample="false"-->
               <!--selectByExampleQueryId="false"></table>-->
        <table tableName="sys_user" domainObjectName="SysUser"></table>
    </context>
</generatorConfiguration>

6.运行maven-generator

7.spring整合Mybatis

未完待续。。。

先把写好的demo放上，有兴趣的小伙伴可以下载试试

码云地址：SSMdemo（https://gitee.com/fyz295039245/SSMDemo）

PS：内部的.keep文件可以忽略，是因为Git不支持空文件夹而创建的！

有点儿累了！！！
