本文主要是介绍整合ssm项目二,对大家解决编程问题具有一定的参考价值,需要的程序猿们随着小编来一起学习吧!

创建maven工程,设置本地仓库

添加web项目

添加pom.xml依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        </dependency>
    <!--spring -jdbc-->
        <dependency>

            <scope>test</scope>
        </dependency>

    </dependencies>
</project>

添加完依赖将依赖添加进project structure里的web-inf的lib下

编写web.xml

<?xml version="1.0" encoding="UTF-8"?>
<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">

    <!--固定步骤1.配置dispatcherservlet-->
    <servlet>
        <servlet-name>springmvc</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:applicationContext.xml</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>springmvc</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--2.配置springmvc的乱码过滤,一定要放在所有的过滤器之前-->
    <filter>
        <filter-name>encoding</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>encoding</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

<!--    使用rest风格的URI,将页面普通的post请求转换为指定的delete或者put请求-->
    <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>
</web-app>

在resources下编写applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/context/spring-context.xsd
                    http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/tx
                    http://www.springframework.org/schema/tx/spring-tx.xsd
                    http://www.springframework.org/schema/aop
                    http://www.springframework.org/schema/aop/spring-aop.xsd">

    <import resource="classpath:spring-dao.xml"/>
    <import resource="classpath:spring-mvc.xml"/>
    <import resource="classpath:spring-service.xml"/>

</beans>

编写spring-dao.xml

<?xml version="1.0" encoding="UTF-8"?>
<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:aop="http://www.springframework.org/schema/aop"
       xmlns:tx="http://www.springframework.org/schema/tx"
       xmlns:p="http://www.springframework.org/schema/p"
       xsi:schemaLocation="
                    http://www.springframework.org/schema/context
                    http://www.springframework.org/schema/context/spring-context.xsd
                    http://www.springframework.org/schema/beans
                    http://www.springframework.org/schema/beans/spring-beans.xsd
                    http://www.springframework.org/schema/tx
                    http://www.springframework.org/schema/tx/spring-tx.xsd
                    http://www.springframework.org/schema/aop
                    http://www.springframework.org/schema/aop/spring-aop.xsd">

    <!-- 1.关联数据库配置文件-->
    <context:property-placeholder location="classpath:db.properties"/>

    <!--   2.连接池
    dbcp半自动化操作,不能自动连接
    c3p0自动化操作(自动化的加载配置文件,并且可以自动设置到对象中)
    druid
    hikari
    -->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.driver}"></property>
        <property name="jdbcUrl" value="${jdbc.url}"></property>
        <property name="user" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
    </bean>


<!--=======================================================================================================-->


    <!--    3.配置spring和mybatis的整合sqlSessionFactory-->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!-- 绑定mybatis全局配置文件-->
        <property name="configLocation" value="classpath:mybatis-config.xml"/>
        <!--指定mybatis,mapper文件的位置-->
        <property name="mapperLocations" value="classpath:mapper/*.xml"></property>
    </bean>

    <!-- 配置dao接口扫描包,动态的实现了dao接口可以注入到spring容器中-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <!--注入sqlsessionfactory-->
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"/>
        <!--要扫描的包-->
        <property name="basePackage" value="com.xu.dao"/>
    </bean>
</beans>

编写外部数据源db.properties

#mysql8.0+   com.mysql.cj.jdbc.Driver
jdbc.driver=com.mysql.jdbc.Driver
#如果使用的是mysql8.0及以上的版本,要增加一个时区的配置serverTimezone=Asia/Shanghai
jdbc.url=jdbc:mysql://localhost:3306/ssm_crud?userSSL=true&userUnicode=true&characterEncoding=UTF8
jdbc.username=root
jdbc.password=root

编写spring-service.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"

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

    <!--扫描service下的包-->
    <context:component-scan base-package="com.xu.service"/>

    <!--    将所有的业务类注入到spring,可以通过配置或注解实现-->


    <!-- 声明式事务配置-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!-- 注入数据源-->
        <property name="dataSource" ref="dataSource"/>
    </bean>

    <!--开启基于注解的事务,使用xml配置形式的事务(主要都是用配置式)-->
    <aop:config>
        <!--切入点表达式-->
        <aop:pointcut id="txPoint" expression="execution(* com.xu.service..*(..))"/>
        <aop:advisor advice-ref="txAdvice" pointcut-ref="txPoint"/>
    </aop:config>

    <!--配置事务如何切入-->
    <tx:advice id="txAdvice" transaction-manager="transactionManager">
        <tx:attributes>
            <!--*代表切入点切入的所有方法都是事务方法-->
            <tx:method name="*"/>
            <!--以get开始的所有方法 ,查询只读-->
            <tx:method name="get" read-only="true"/>
        </tx:attributes>
    </tx:advice>
</beans>

编写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/mvc
          http://www.springframework.org/schema/mvc/spring-mvc.xsd">

    <!--1.注解驱动-->
    <mvc:annotation-driven/>

    <!--2.静态资源过滤-->
    <mvc:default-servlet-handler/>

    <!--3.开启注解扫描-->
    <context:component-scan base-package="com.xu.controller"/>


    <!--4.添加视图解析器:模板引擎有Thymeleaf freemarker等等,这里用的是modelandview-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" id="InternalResourceViewResolver">
        <!--前缀-->
        <property name="prefix" value="/WEB-INF/jsp/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

编写mybatis核心配置文件mybatis-config.xml

<?xml version="1.0" encoding="UTF8" ?>
<!DOCTYPE configuration
        PUBLIC "-//mybatis.org//DTD Config 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-config.dtd">

    <typeAliases>
        <!--给每个实体类的bean对象取别名-->
        <package name="com.xu.entity"/>
    </typeAliases>
</configuration>

建好相关的包

 

引入jQuery和bootstrap

<%--    引入jQuery--%>
      <script src="static/js/jquery-3.6.0.js"></script>
<%--    引入bootstrap--%>
    <link href="static/bootstrap-3.4.1-dist/css/bootstrap.css/bootstrap.min.css" rel="stylesheet">
    <script src="static/bootstrap-3.4.1-dist/js/bootstrap.js/bootstrap.min.js"></script>
