idea-gradle-springmvc-web

1.首先创建gradle项目，详细参考http://www.jianshu.com/p/c0fc6a91d3e7

2.springmvc的一些配置：

a. build.gradle文件，引入一些必要的包文件

group 'Example'
version '1.0-SNAPSHOT'

apply plugin: 'java'
apply plugin: 'war'

sourceCompatibility = 1.5

repositories {
    maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
    mavenLocal()
    jcenter()
    maven { url "http://repo.maven.apache.org/maven2/"}
    maven { url 'https://repo.spring.io/libs-milestone'}
    mavenCentral()
}

String springVersion = '4.1.0.RELEASE'
String slf4jVersion = '1.7.7'

configurations.all {

        if (details.requested.group == 'org.springframework') {
            details.useVersion springVersion
        }
    }
}

3. Controller

package com.example.controller;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

/**
 * Created by Administrator on 2017/4/11.
 */

@Controller
@RequestMapping("/example")
public class HomeControler {
    @RequestMapping(value = "", method = RequestMethod.GET)
    public String helloWorld() {
        return "home";
    }
}

4. 访问路径：http://localhost:8080/example

5. 项目目录结构
