[Java知识库]SSM框架整合

SSM整合

一、创建一个Maven项目

File -> NewProject
创建Maven项目

二、声明war打包方式并创建web项目目录结构

2.1 创建web项目结构

有关于Maven不了解的小伙伴不要灰心，请参考Maven教程

声明war包打包方式，即在pom.xml文件中加入一行标签<packaging>war</packaging>，随后创建web项目目录结构！

手动构建web项目结构
基于main目录下创建webapp文件夹
基于webapp目录创建WEB-INF文件夹
基于WEB-INF目录创建web.xml文件
xml文件内容展示
基于webapp目录创建index.jsp文件
目录展示 （完整的web项目目录结构）

2.2 所需依赖

<!-- servlet -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>servlet-api</artifactId>
    <version>2.5</version>
</dependency>

<!-- jsp -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jsp-api</artifactId>

</dependency>

<!-- jstl -->
<dependency>
    <groupId>javax.servlet</groupId>
    <artifactId>jstl</artifactId>
    <version>1.2</version>
</dependency>

三、引入tomact服务器并设置

关于Tomact服务的引入，需要我们手动添加tomact服务

添加tomact服务后，如果对tomact服务器在IDEA中的开发流程不熟悉的小伙伴，不要灰心。请参考tomact服务器基础和开发步骤即可，此文章中详细讲到了关于tomact的各种知识点！

添加tomact服务

6.3 所需依赖

所需依赖： Jackson（Json解析）、SpringMVC核心（webmvc）、IO、文件上传（因文件上传依赖与其他依赖重名所以需要排除其他依赖）、FastJson（Json解析）、二维码所需依赖（排除其他影响的二维码依赖）

七、IDEA创建模板

新建模板
创建模板并添加代码/名称/文件类型
使用模板

依赖模板如下：
