在IDEA上建立SSM專案配置

一,建立Maven專案

二,在pom.xml檔案中新增必要的相關依賴spring,springmvc,mybatis,資料庫連線池,驅動包,其他(jstl,jsp,servletr-  api,junit)等

注:依賴匯入時spring的儘量版本號一致

三,引用bootstrap前端框架

1,在官網下載:https://v3.bootcss.com/

2,在專案webapp檔案下建立靜態資料夾static將下載好的bootstrap資料夾放入下面

3,在再static資料夾下建立js資料夾放入jquery檔案

    (推薦一個網站有多個版本的jquery檔案提供下載)

     js檔案下載地址:http://www.jq22.com/jquery-info122

結構如下:

4,在jsp檔案中引入必須的檔案

    <!--引入jquery-->
    <script type="text/javascript" src="static/js/jquery-3.3.1.min.js"/>
    <!--引入樣式-->
    <link href="static/bootstrap-3.3.7-dist/css/bootstrap.min.css"/>
    <script type="text/javascript" src="static/bootstrap-3.3.7-dist/js/bootstrap.min.js"/>

四,SSM整合關鍵配置檔案

1,spring配置(放在資原始檔夾resource下)

先建立資料庫連線相關檔案db.properties(放在資原始檔夾resource下)

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context-3.0.xsd
   http://www.springframework.org/schema/mvc
   http://www.springframework.org/schema/mvc/spring-mvc.xsd
   http://www.springframework.org/schema/tx
   http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
   http://www.springframework.org/schema/aop
   http://www.springframework.org/schema/aop/spring-aop.xsd
">

    <context:component-scan base-package="cn.xf">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>
    
    <!--spring的配置檔案,這裡主要配置和業務邏輯有關的-->
    <!--=====================資料來源,事務控制,XXX=====================-->
    <context:property-placeholder location="classpath:dbconfig.properties"/>
    <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="jdbcUrl" value="${jdbc.jdbcUrl}"/>
        <property name="driverClass" value="${jdbc.driverClass}"/>
        <property name="user" value="${jdbc.user}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!--==================================================================-->

    <!--===============================配置Mybatis的整合=======================-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!--指定MyBatis全域性配置檔案的位置-->
        <property name="configLocation" value="classpath:mybatis-cinfig.xml"/>
        <property name="dataSource" ref="pooledDataSource"/>
        <!--指定mybatis,mapper檔案的位置-->
        <property name="mapperLocations" value="classpath*:/mapper/*Mapper.xml"/>
    </bean>


    <!--配置掃描器,將mybatis介面的實現加入到ioc容器中-->
    <bean  class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--掃描所有的dao介面的實現,加入到ioc容器中-->
        <property name="basePackage" value="cn.xf.dao"/>
    </bean>
    <!--=========================================================================-->

    <!--配置一個可以執行批量操作的sqlSession-->
    <bean id="sqlSession" class="org.mybatis.spring.SqlSessionTemplate">
        <constructor-arg name="sqlSessionFactory" ref="sqlSessionFactory"/>
        <constructor-arg name="executorType" value="BATCH"></constructor-arg>
    </bean>
    <!--====================================事務控制的配置===============================-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--控制住資料來源-->
        <property name="dataSource" ref="pooledDataSource"></property>
    </bean>
    <!--開啟基於註解的事務,使用xml配置形式的事務-->
    <aop:config>
        <!--切入點表示式-->
        <aop:pointcut expression="execution(* cn.xf.service..*(..))" id="txPomnit"/>
        <!--配置事務增強-->
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPomnit"/>
    </aop:config>

    <!--配置事務增強,事務如何切入-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">

        <tx:attributes>
            <!--所有方法都是事務方法-->
            <tx:method name="*"></tx:method>
            <!--以get開頭的所有方法-->
            <tx:method name="get*" read-only="true"/>
        </tx:attributes>
    </tx:advice>
    <!--==========================================================================-->

</beans>

2,springmvc配置(配置檔案放在wenapp/WEB-INF下)

<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
   http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
   http://www.springframework.org/schema/context
   http://www.springframework.org/schema/context/spring-context-3.0.xsd
   http://www.springframework.org/schema/mvc
   http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--
    以下是有關HelloWeb-servlet.xml檔案的重點說明:
    [servlet-name]-servlet.xml檔案將用於建立定義的bean,
    它會覆蓋在全域性範圍中使用相同名稱定義的任何bean的定義。
    <context:component-scan ...>標籤將用於啟用Spring MVC註釋掃描功能,
    允許使用@Controller和@RequestMapping等註釋。InternalResourceViewResolver將定義用於解析檢視名稱的規則。
    根據上面定義的規則,hello的邏輯檢視將委託給位於/WEB-INF/jsp/hello.jsp這個檢視來實現。
    -->
    <!--springmvc的配置檔案,包含網站跳轉邏輯的控制,配置-->
    <context:component-scan base-package="cn.xf" use-default-filters="false">
        <!--只掃描控制器-->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--配置檢視解析器,方便頁面返回-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/views/"/>
        <property name="suffix" value=".jsp"/>
    </bean>
    <!--兩個標準配置-->
    <!--將springmvc不能處理的請求交給tomcat-->
    <mvc:default-servlet-handler/>
    <!--能支援springmvc的高階的一些功能,jsr303校驗,快捷的ajax..對映動態請求-->
    <mvc:annotation-driven />

</beans>

3,配置mybatis(在sources資原始檔夾下建立)

<?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="mapUnderscoreToCamelCase" value="true"/>
    </settings>
    <typeAliases>
        <package name="cn.xf.bean"/>
    </typeAliases>
</configuration>

4,配置web.xml檔案

<!--1 啟動spring容器-->
  <context-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>classpath:applicationContext.xml</param-value>
  </context-param>

  <listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener>

  <!--2, Springmvc的前端控制器,攔截所有請求-->
  <servlet>
    <servlet-name>dispatcherServlet</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>dispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  <!--3 字元過濾器-->
  <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>forceRequestEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
    <init-param>
      <param-name>forceResponseEncoding</param-name>
      <param-value>true</param-value>
    </init-param>
  </filter>
  <filter-mapping>
    <filter-name>CharacterEncodingFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

  <!--4 使用Rest風格的url,將頁面普通的post請求轉為指定的delete或者put-->
  <filter>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
  </filter>
  <filter-mapping>
    <filter-name>HiddenHttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
  </filter-mapping>

五,使用mybatis逆向工程

1,在專案更目錄下建立配置檔案配置資料庫中的表和專案對映

注:現在專案下建立相應的資料夾包

如下:

<?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>


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

        <!--設定不自動生成註釋-->
        <commentGenerator>
            <property name ="suppressAllComments" value ="true"/>
        </commentGenerator>
        <!--配置資料庫連線-->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="資料庫連線地址"
                        userId="資料庫使用者名稱"
                        password="密碼">
        </jdbcConnection>

        <javaTypeResolver >
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!--指定javaBean生成位置-->
        <javaModelGenerator
                targetPackage="cn.xf.bean"
                targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!--指定sql對映檔案生產的位置-->
        <sqlMapGenerator
                targetPackage="mapper"
                targetProject=".\src\main\resources">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!--指定dao介面生成的位置,mapper介面-->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="cn.xf.dao"
                             targetProject=".\src\main\java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        <!--table指定每個表的生成策略-->
        <table tableName="資料庫中的表名" domainObjectName="對映到專案中的實體名"></table>
        <table tableName="資料庫中的表名" domainObjectName="對映到專案中的實體名"></table>

    </context>
</generatorConfiguration>

2,執行mybatis逆向工程

在包中建立一個java檔案

package cn.xf.test;

import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;

import java.io.File;
import java.io.IOException;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

public class MBGTest {
    public static void main(String[] args) throws IOException, XMLParserException, InvalidConfigurationException, SQLException, InterruptedException {
        List<String> warnings = new ArrayList<String>();
        boolean overwrite = true;
        File configFile = new File("建立mybatis逆向工程的配置檔案");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
    }
}

3,點選執行該類,則會在相應的資料夾下生成檔案

注:想了解更多mybatis配置和逆向工程的,請移步到mybatis官網,有更詳細的文件說明

網址:http://www.mybatis.org/mybatis-3/

就這樣ssm的基本配置就完成啦......

如有什麼不太清楚的和建議,請多多留言,大家互相交流學習啊。。。
