Spring boot Gradle项目搭建

Spring boot Gradle项目搭建

---

使用IDEA创建Gradle工程

????操作大致为：File->new->Project->Gradle(在左侧选项栏中)

????创建常规以后生成的工程目录如下：

• build
• gradle
  • wrapper
    • gradle-wrapper.jar
    • gradle-wrapper.properties
• src
  • java
  • resources
• test
  • java
  • resources
• build.gradle
• gradlew
• gradlew.bat
• settings.gradle

配置Spring boot

????下面需要对两个文件进行编辑：

????build.gradle文件修改后的内容如下,依赖一般是前面是groupId，中间是artifactId，第三个一般是版本。在repositories配置使用阿里云的仓库，避免下载过慢。

plugins {
    id 'java'
    id 'com.gradle.build-scan' version '2.0.2'
    id 'org.springframework.boot' version '2.0.5.RELEASE'
    id 'io.spring.dependency-management' version '1.0.7.RELEASE'
}

group 'seckill'
version '1.0-SNAPSHOT'

sourceCompatibility = 1.8

repositories {
    maven { url "http://maven.aliyun.com/nexus/content/groups/public/" }
    mavenCentral()
}

dependencies {
    testCompile group: 'junit', name: 'junit', version: '4.12'

    implementation 'org.springframework.boot:spring-boot-dependencies:2.0.5.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-web'

    testImplementation 'org.springframework.boot:spring-boot-starter-test'

    components {
        withModule('org.springframework:spring-beans') {
            allVariants {
                withDependencyConstraints {
                    // Need to patch constraints because snakeyaml is an optional dependency
                    it.findAll { it.name == 'snakeyaml' }.each { it.version { strictly '1.19' } }
                }
            }
        }
    }
}

buildScan {

    // always accept the terms of service
    termsOfServiceUrl = 'https://gradle.com/terms-of-service'
    termsOfServiceAgree = 'yes'

    // always publish a build scan
    publishAlways()
}

????setting.gradle文件修改后的内容如下：

rootProject.name = 'seckill'
enableFeaturePreview('IMPROVED_POM_SUPPORT')

编写类

????首先在src/java下生成源码目录com.seckill.spring(相当于com/seckill/spring)

????在src/java下创建程序入口类Application.java,其内容如下：

package com.seckill.spring;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

????在src/java/com.seckill.spring下创建目录controllers，并在controllers目录创建类：HelloWorld，在其中定义根路由并返回Hello World，其代码如下：

package com.seckill.spring.controllers;

import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import java.util.HashMap;
import java.util.Map;

@RestController
public class HelloWorld {
    @RequestMapping(value = "/", method = RequestMethod.GET)
    public Map helloWorld() {
        Map<String, Object> ret = new HashMap<>();
        ret.put("ret", "Hello World");
        return ret;
    }
}

运行访问

• 运行Application类，可以在控制台看到起默认监听在8080端口
• 浏览器访问:localhost:8080,可以看到返回字符串Hello World
