4.加入spring配置文件(applicationContext.xml)

使用IDEA搭建ssm框架的详细图文教程

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


 <!-- spring 配置文件 主要配置和业务逻辑有关的 -->

 <!-- 配置数据库连接的相关信息 dbconfig.properties也定义在resources文件夹下-->
 <context:property-placeholder location="classpath:dbconfig.properties"/>
 <!-- 数据源 -->
 <bean id="pooledDataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
  <property name="jdbcUrl" value="${jdbc.jdbcUrl}"></property>
  <property name="driverClass" value="${jdbc.driverClass}"></property>
  <property name="user" value="${jdbc.user}"></property>
  <property name="password" value="${jdbc.password}"></property>
 </bean>


 <!--扫描com.ssm所有的除了@Controller以外的其它注解,也就是service和dao层的注解
  service层注解 @Service dao层注解@Repository
 -->
 <context:component-scan base-package="com.ssm">
  <!-- 不能扫描控制器 -->
 <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan>


 <!-- 把mybatis和spring整合在一起,mybatis-config.xml也和applictionContext.xml同文件夹
   mapper/星号.xml 指定要扫描的映射文件(sql语句的xml文件)的路径,和applictionContext.xml同文件夹 -->
 <!-- 配置和mybatis的整合 -->
 <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
  <!-- 指定mybatis 全局配置文件的位置 -->
  <property name="configLocation" value="classpath:mybatis-config.xml"></property>
  <property name="dataSource" ref="pooledDataSource"></property>
  <!-- 指定mybatismapper文件的位置 -->
  <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
 </bean>



 <!-- 配置扫描器,将mybatis接口的实现加入到ioc容器中 -->
 <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
  <!-- 扫描所有的dao接口 -->
  <property name="basePackage" value="com.ssm.dao"></property>
 </bean>

 <!-- 事务控制的配置,为所有的非get开头的service层方法织入事务 -->

 <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
  <!-- 控制数据源 -->
  <property name="dataSource" ref="pooledDataSource"></property>
 </bean>

 <aop:config>
  <!-- 切入点表达式 -->
  <aop:pointcut expression="execution(* com.liuzhan.service..*(..) )" id="txPoint"/>
  <!-- 配置事务 -->
  <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
 </aop:config>
 <!-- 配置事务增强 事务如何切入 -->
 <tx:advice id="txAdvice">

  <tx:attributes>
   <!-- 所有方法都是事务方法 -->
   <tx:method name="*"/>
   <!-- 以get开头的所有方法 -->
   <tx:method name="get*" read-only="true"/>
  </tx:attributes>
 </tx:advice>
</beans>

5.配置数据库连接相关信息(dbconfig.properties)

使用IDEA搭建ssm框架的详细图文教程

#数据库连接
jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm-crud?useUnicode=true&characterEncoding=utf-8&serverTimezone=GMT%2B8
#加载驱动
jdbc.driverClass=com.mysql.cj.jdbc.Driver
#数据库登录用户名
jdbc.user=root
#密码
jdbc.password=root

6.mybatis配置文件(mybatis-config.xml)

使用IDEA搭建ssm框架的详细图文教程

<!DOCTYPE configuration
  PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
  "http://mybatis.org/dtd/mybatis-3-config.dtd">

<configuration>

</configuration>

注意:这里要建个mapper空文件,因为spring的配置文件applicationContext.xml
中有一项配置要扫描这个文件夹下的所有映射文件

7.配置web.xml文件

web.xml
项目启动,先加载web.xml文件的配置

使用IDEA搭建ssm框架的详细图文教程

<!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>
 <display-name>Archetype Created Web Application</display-name>

 <!-- 1.启动spring容器,加载spring配置文件applicationContext.xml -->
 <!-- needed for ContextLoaderListener -->
 <context-param>
 <param-name>contextConfigLocation</param-name>
 <param-value>classpath:applicationContext.xml</param-value>
 </context-param>

 <!-- Bootstraps the root web application context before servlet initialization -->
 <listener>
 <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
 </listener>


 <!-- 2. 配置spring mvc 的前端控制器,DispatcherServlet类拦截所有请求,交给controller处理
 加载spring mvc配置文件(dispatcherServlet-servlrt.xml,还没有建) -->
 <!-- The front controller of this Spring Web application, responsible for handling all application requests -->
 <servlet>
 <servlet-name>dispatcherServlet</servlet-name>
 <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
 <!-- 不写,写的话需要建个springmvc.xml就不需要dispatcherServlet-servlrt.xml -->
 <!-- <init-param>-->
 <!--  <param-name>contextConfigLocation</param-name>-->
 <!--  <param-value>classpath:springmvc.xml</param-value>-->
 <!-- </init-param>-->
 <load-on-startup>1</load-on-startup>
 </servlet>

 <!-- Map all requests to the DispatcherServlet for handling -->
 <servlet-mapping>
 <servlet-name>dispatcherServlet</servlet-name>
 <url-pattern>/</url-pattern>
 </servlet-mapping>



 <!-- 编码过滤器,防止出现乱码 -->
 <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>
 </filter>

 <filter-mapping>
 <filter-name>characterEncodingFilter</filter-name>
 <url-pattern>/*</url-pattern>
 </filter-mapping>
</web-app>

8.配置spring mvc配置文件(dispatcherServlet-servlet.xml)

spring mvc就是充当控制器,替代servlet

<?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">



 <!-- spring mvc主要作用就是充当控制器,只需要扫描controller -->
 <context:component-scan base-package="com.ssm" use-default-filters="false">
  <!-- 因为是spring mvc 只需要扫描控制器 -->
  <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
 </context:component-scan>

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

 <!-- 两个标准配置 -->
 <!-- 将springmvc 不能处理的请求交给tomcat 例如静态资源 -->
 <mvc:default-servlet-handler/>

 <mvc:annotation-driven>
  <mvc:message-converters>
   <bean class="org.springframework.http.converter.StringHttpMessageConverter"/>
   <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"/>
  </mvc:message-converters>
 </mvc:annotation-driven>
</beans>

9.使用逆向工程前配置

使用IDEA搭建ssm框架的详细图文教程

<?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">
  <!-- 配置数据连接信息 -->
  <jdbcConnection driverClass="com.mysql.jdbc.Driver"
      connectionURL="jdbc:mysql://localhost:3306/ssm-crud?useUnicode=true&amp;characterEncoding=utf-8&amp;serverTimezone=GMT%2B8"
      userId="root"
      password="root">
  </jdbcConnection>

  <javaTypeResolver >
   <property name="forceBigDecimals" value="false" />
  </javaTypeResolver>

  <!-- 指定java bean生成的位置 -->
  <javaModelGenerator targetPackage="com.ssm.entity" targetProject=".\src\main\java">
   <property name="enableSubPackages" value="true" />
   <property name="trimStrings" value="true" />
  </javaModelGenerator>

  <!-- 指定sql映射文件生成的位置 -->
  <sqlMapGenerator targetPackage="mapper"
       targetProject=".\src\main\resources">
   <property name="enableSubPackages" value="true" />
  </sqlMapGenerator>
  <!-- 指定dao接口生成的位置 -->
  <javaClientGenerator type="XMLMAPPER"
        targetPackage="com.ssm.dao"
        targetProject=".\src\main\java">
   <property name="enableSubPackages" value="true" />
  </javaClientGenerator>
  <!-- 指定每个表的生成策略,表和类对应关系 -->
  <table tableName="tbl_emp" domainObjectName="Employee"></table>
  <table tableName="tbl_dept" domainObjectName="Department"></table>
 </context>
</generatorConfiguration>

10.使用逆向工程生成接口、实体类、映射文件

使用IDEA搭建ssm框架的详细图文教程

MBGTest.java

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("mbg.xml");
  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);
 }
}

逆向工程生成
