教你使用idea搭建ssm详细教程（Spring+Spring Mvc+Mybatis）

一、创建maven项目

我使用的是汉化的idea

可以选择原型，我这里没有选择

输入项目名称，完成创建

二、配置tomcat

选择运行编辑配置

点加号找见tomcat,点击确定

三、添加web模块

点击文件进入项目结构，选择模块

点加号找见web，点击确定

四、添加工件

点击加号添加，并将可用元素中的jar包，右击，加入lib中

五、为项目添加tomcat的jar包

选择模块，选择项目名

选择web服务

六、idea不会编译src下的mapper.xml文件

让idea编译器不忽略src下的mapper.xml配置文件,自动会忽略，而sts不会
在pom文件中加入以下代码就好

 <build>
        <resources>
            <resource>
                <directory>src/main/java</directory>
                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
    </build>

七、将Spring和Mybatis文件位置

放在resources下

八、pom.xml

<?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>org.example</groupId>
    <artifactId>Poject_Stu</artifactId>
    <version>1.0-SNAPSHOT</version>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
    </properties>

    <!--让idea编译器不忽略src下的mapper.xml配置文件,自动会忽略，而sts不会-->
    <build>
        <resources>
            <resource>

                <includes>
                    <include>**/*.xml</include>
                </includes>
            </resource>
        </resources>
    </build>
