ssm整合(maven版)

首先创建项目：

填写组织名称跟war包名称

选择本地maven仓库

填写项目名称跟选址项目储存位置，点击finish即可成功创建项目

项目创建成功

如果没有以上项目列表可以等一会或者按一下步骤抄作

创建项目需要的文件夹

使文件夹变成系统可读文件夹：

选择后：

在java中创建对应包

配置pom.xml，导入需要的jar包

//在pom文件中找到这个标签，配置所需要的jar包
//里面每一个<dependency>配置一个jar包
<dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>


</dependencies>

所需要的jar都在mvn中查找：https://mvnrepository.com/

你需要什么jar包直接搜索就可以了

例如我需要连接数据库的jar，直接搜索mysql

按照上面的配置方法你可以将你需要的jar包全部配置好，配置完成后点击idea右上角的maven中的刷新按钮即可将jar包引入进来

配置完pom.xml之后配置web.xml

配置spring(applicationContext.xml)、外部数据库信息(dbconfig.properties)、springmvc(springmvc.xml)、mybatis

applicationContext.xml：

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

    <!-- ===============事务控制的配置 ================-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <!--控制住数据源  -->

        </tx:attributes>
    </tx:advice>

    <!-- Spring配置文件的核心点（数据源、与mybatis的整合，事务控制） -->
</beans>

dbconfig.properties(填写你的):

jdbc.jdbcUrl=jdbc:mysql://localhost:3306/ssm_crud
jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.user=root
jdbc.password=123456

springmvc.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"

        <!--只扫描控制器。  -->
        <context:include-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
    </context:component-scan>

    <!--配置视图解析器，方便页面返回  -->
    <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 -->
    <mvc:default-servlet-handler/>
    <!-- 能支持springmvc更高级的一些功能，JSR303校验，快捷的ajax...映射动态请求 -->
    <mvc:annotation-driven/>
</beans>

mybatis:

<?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>
        <!--设置驼峰命名规则-->
        <setting name="mapUnderscoreToCamelCase" value="true"/>
    </settings>

    

    <typeAliases>
        <!--起别名 引用时只要打相应的类名即可-->
        <package name="com.dpf.crud.bean"/>
    </typeAliases>

    <!-- 注册插件 -->
    <plugins>
        <plugin interceptor="com.github.pagehelper.PageInterceptor">
            <!--分页参数合理化  -->
            <property name="reasonable" value="true"/>
        </plugin>
    </plugins>

</configuration>

到这里整合就基本完成了。
