SSM环境整合

本文主要是介绍SSM环境整合，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！

SSM环境整合

IDEA下创建项目

创建Maven对应的Web项目

配置 pom.xml

修改 JDK 版本

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <maven.compiler.source>1.8</maven.compiler.source>
        <maven.compiler.target>1.8</maven.compiler.target>
    </properties>

添加坐标依赖
