环境准备：jdk1.8+tomcat8+idea+gradle
1.创建项目SSM
使用gradle创建项目，按照提示如下
image.png
输入项目名称，组名

image.png
选择本地安装gradle
image.png
点击下一步创建成功

如图所示，项目结构不完整，下面完善项目结构
手动创建文件夹java和resources，WEB-INF
image.png
创建web.xml
image.png
创建成功
image.png
配置tomcat

image.png
在web.xml中添加默认访问页面

启动项目，访问localhost:8080如下，项目创建成功

2.搭建ssm
配置文件build.gradle
更改jdk版本，使用阿里的maven仓库，导入依赖，在此附上spring各个依赖包的作用，方便大家理解。（有时我也很懵逼）http://blog.csdn.net/sunchen2012/article/details/53939253

最终项目结构如下，相关包大家自己修改，创建。要和配置文件里对应
image.png
至此整个项目搭建完成，下面进行简单的测试。在WEB-INF/views下新建testIndex.jsp文件
<%@ page contentType="text/html;charset=UTF-8" language="java" %>
<html>
<head>
<title>测试</title>
</head>
<body>
这是一个测试页面
</body>
</html>
创建TestController
package com.lmandy;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
@RequestMapping("/test")
@Controller
public class TestController {
@RequestMapping("index")
public String testIndex(){
return "testIndex";
//对应刚刚创建的jsp文件名，这里用的是逻辑视图
}
}
逻辑视图解析器已在spring-mvc.xml配置
<!--视图解析器-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
下面启动项目开始访问 http://localhost:8080/test/index如下访问成功
image.png
至此可以进行开发了
在此附上demo的地址 https://gitee.com/lmandy/text_gradle.git
创建数据库:account
创建:test_user表 此处注意要和jdbc中对应
CREATE TABLE `test_user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(64) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
