ssm整合笔记配置文件版

1.创建maven-web项目

2.在pom.xml文件里加入jar包坐标

<?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"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.itheima</groupId>
    <artifactId>my_ssm</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>war</packaging>

    <properties>

    </properties>

                </configuration>
            </plugin>
        </plugins>
    </build>
</project>

3.创建webapp->WEB-INF->web.xml文件，在配置文件中读入applicationContext.xml和spring-mvc文件

<?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">
    <!--启动服务器时，通过监听器加载spring运行环境-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>

    <!--    配置SpringMVC核心控制器，拦截所有请求-->
    <servlet>
        <servlet-name>DispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath*:spring-mvc.xml</param-value>
        </init-param>
    </servlet>
    <servlet-mapping>
        <servlet-name>DispatcherServlet</servlet-name>
        <url-pattern>/</url-pattern>
    </servlet-mapping>

    <!--乱码处理过滤器，与Servlet中使用的完全相同，差异之处在于处理器的类由Spring提供-->
    <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>

    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath*:applicationContext.xml</param-value>
    </context-param>
</web-app>

4.jdbc.properties

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/ssm_db
jdbc.username=root
jdbc.password=1234

5.application.xml，mybatis整合进去

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:context="http://www.springframework.org/schema/context"
       xmlns:tx="http://www.springframework.org/schema/tx"
       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
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    
    <context:component-scan base-package="com.itheima">
        <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>


    <!--加载properties文件-->
    <context:property-placeholder location="classpath*:jdbc.properties"/>

    <!--数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driver}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

    <!--整合mybatis到spring中-->
    <bean class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="typeAliasesPackage" value="com.itheima.domain"/>

        <!--分页插件-->
        <property name="plugins">
            <array>
                <bean class="com.github.pagehelper.PageInterceptor">
                    <property name="properties">
                        <props>
                            <prop key="helperDialect">mysql</prop>
                            <!--pageNum<=0 时会查询第一页，pageNum>pageSize（超过总数时），会查询最后一页-->
                            <prop key="reasonable">true</prop>
                        </props>
                    </property>
                </bean>
            </array>
        </property>
    </bean>

    <!--映射扫描-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.itheima.dao"/>
    </bean>

    <!--开启注解式事务-->
    <tx:annotation-driven transaction-manager="txManager"/>

    <!--事务管理器-->
    <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>


</beans>

6.springmvc.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:mvc="http://www.springframework.org/schema/mvc"
       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
        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">

    <!--扫描加载所有的控制类-->
    <context:component-scan base-package="com.itheima.controller"/>

<!--    放行静态资源-->
    <!--SpringMVC提供的通用资源放行方式-->
    <mvc:default-servlet-handler/>
    <!--必须组合使用-->
    <mvc:annotation-driven>
<!--        配置后解决中文乱码问题-->
        <mvc:message-converters>
            <bean class="org.springframework.http.converter.StringHttpMessageConverter">
                <constructor-arg value="UTF-8" />
            </bean>
        </mvc:message-converters>
    </mvc:annotation-driven>

<!--    配置视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--        设置访问前缀-->
        <property name="prefix" value="/WEB-INF/page/"/>
<!--        设置访问后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>
</beans>

7.domain、controller、service、dao层

8.在resources下建立xxxDao.xml，必须和xxxdao的全类名相同

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.itheima.dao.UserDao">

    <!--添加-->
    <insert id="save" parameterType="user">
        insert into user(userName,password,realName,gender,birthday)values(#{userName},#{password},#{realName},#{gender},#{birthday})
    </insert>

    <!--删除-->
    <delete id="delete" parameterType="int">
        delete from user where uuid = #{uuid}
    </delete>

    <!--修改-->
    <update id="update" parameterType="user">
        update user set userName=#{userName},password=#{password},realName=#{realName},gender=#{gender},birthday=#{birthday} where uuid=#{uuid}
    </update>

    <!--查询单个-->
    <select id="get" resultType="user" parameterType="int">
        select * from user where uuid = #{uuid}
    </select>

    <!--分页查询-->
    <select id="getAll" resultType="user">
        select * from user
    </select>

    <!--登录-->
    <select id="getByUserNameAndPassword" resultType="user" >
        select * from user where userName=#{userName} and password=#{password}
    </select>

</mapper>
