Gradle构建SpringBoot项目

1、新建项目

因为默认是勾选Java选项的，为了构建一个适合多模块的项目，去掉勾选，如上图。

接下来右键单击项目名创建一个Model,此时一个纯净的gradle项目结构便已经完成，如果是多模块项目，那么便可以创建多个Model,接下来便是配置yml文件。

1.1、首先配置最外层的build.gradle文件。个人整合了一部分常用的jar包。

buildscript {
    // 定义变量
    ext {
        springBootVersion = '2.2.2.RELEASE'
        ALI_REPOSITORY_URL = 'http://maven.aliyun.com/nexus/content/groups/public'
    }
    // 仓库地址
    repositories {
        // 先从阿里云maven仓库中去下载，没有再去maven*仓库
        maven {
            url ALI_REPOSITORY_URL
        }
        mavenCentral()

    }
    // 构建时所需要的插件或者是其他的依赖
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }

}
// 所有模块的总仓库地址
allprojects {
    // 在build.gradle文件中直接声明的依赖项、仓库地址等信息是项目自身需要的资源。
    repositories {
        maven {
            url ALI_REPOSITORY_URL
        }
    }
}
subprojects {
    apply plugin: 'java'
    apply plugin: 'war';
    apply plugin: 'idea'
    apply plugin: 'io.spring.dependency-management'
    apply plugin: 'org.springframework.boot'
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
    // 指定编码格式
    [compileJava,compileTestJava,javadoc]*.options*.encoding = 'UTF-8'
    version = "1.0.0-SNAPSHOT"  // 开发版本： -SNAPSHOT 正式版本：.RELEASE
//    group = "com.js"
    description = "spring boot in action"
    dependencies {
        //mysql驱动
        compile group: 'mysql', name: 'mysql-connector-java', version: '8.0.11'
        //阿里数据库连接池
        compile group: 'com.alibaba', name: 'druid', version: '1.1.0'
        //SpringBootWeb模块
        compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '2.2.2.RELEASE'
        //springboot的aop切面驱动
        compile group: 'org.springframework.boot', name: 'spring-boot-starter-aop', version: '2.2.2.RELEASE'
        //邮箱服务
        compile group: 'org.springframework.boot', name: 'spring-boot-starter-mail', version: '2.2.2.RELEASE'
        // https://mvnrepository.com/artifact/org.springframework.amqp/spring-rabbit
        compile group: 'org.springframework.amqp', name: 'spring-rabbit', version: '2.2.2.RELEASE'
        //redis驱动
        compile 'org.springframework.boot:spring-boot-starter-data-redis:2.2.2.RELEASE'
        //mybatis需要的
        compile group: 'org.mybatis.spring.boot', name: 'mybatis-spring-boot-starter', version: '1.3.2'
        
        //lombok的jar包
        compileOnly 'org.projectlombok:lombok:1.18.10'
        annotationProcessor 'org.projectlombok:lombok:1.18.10'
        testCompileOnly 'org.projectlombok:lombok:1.18.10'
        testAnnotationProcessor 'org.projectlombok:lombok:1.18.10'

        compile 'org.hibernate:hibernate-validator:5.3.6.Final'
        compile 'com.fasterxml.jackson.core:jackson-databind:2.9.7'
        compile group: 'org.apache.commons', name: 'commons-pool2', version: '2.4.1'

        //swagger驱动
        compile 'io.springfox:springfox-swagger-ui:2.9.2'
        compile 'io.springfox:springfox-swagger2:2.9.2'
        compile 'io.github.swagger2markup:swagger2markup:1.3.1'
        compile 'joda-time:joda-time:2.9.4'
        //Mybatis分页插件
        compile group: 'com.github.pagehelper', name: 'pagehelper-spring-boot-starter', version: '1.2.12'

        // https://mvnrepository.com/artifact/org.apache.httpcomponents/httpclient
        compile group: 'org.apache.httpcomponents', name: 'httpclient', version: '4.5.12'

        // https://mvnrepository.com/artifact/org.apache.commons/commons-lang3
        compile group: 'org.apache.commons', name: 'commons-lang3', version: '3.8.1'

        compile group: 'commons-io', name: 'commons-io', version: '2.4'
        // https://mvnrepository.com/artifact/commons-net/commons-net
        compile group: 'commons-net', name: 'commons-net', version: '3.6'

        compile 'com.github.pagehelper:pagehelper:5.1.4'
        //token插件
//        compile 'com.auth0:java-jwt:3.2.0'
        compile group: 'com.auth0', name: 'java-jwt', version: '3.0.0'
        compile group: 'io.jsonwebtoken', name: 'jjwt', version: '0.9.1'
    }
}

1.2、日志打印相关采用的lombok组件,配置日志的相关文件logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
<configuration  scan="true" scanPeriod="10 seconds">
    <contextName>logback</contextName>
    <!-- 格式化输出：%date表示日期，%thread表示线程名，%-5level：级别从左显示5个字符宽度 %msg：日志消息，%n是换行符-->
    <property name="LOG_PATTERN" value="%date{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n" />
    <!-- 定义日志存储的路径，不要配置相对路径 E:\file\log %i声明每天产生的日志文件后缀-->
    <property name="FILE_PATH" value="D:/logs/%d{yyyy.MM.dd}/%d{yyyy.MM.dd}.%i.log" />

    <!-- 定义日志存储的路径，不要配置相对路径 E:\file\log %i声明每天产生的日志文件后缀-->
    <property name="FILE_ERROR_PATH" value="D:/logs/%d{yyyy.MM.dd}/error/%d{yyyy.MM.dd}.%i.error.log" />
    <!-- 控制台输出日志 -->
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <!-- 日志级别过滤INFO以下 -->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>INFO</level>
        </filter>
        <encoder>
            <!-- 按照上面配置的LOG_PATTERN来打印日志 -->
            <pattern>${LOG_PATTERN}</pattern>
        </encoder>
    </appender>

    <!--只保存error日志-->
    <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>ERROR</level>
        </filter>
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${FILE_ERROR_PATH}</fileNamePattern>
             <!--keep 15 days' worth of history-->
            <maxHistory>30</maxHistory>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!-- 日志文件的最大大小 -->
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <!-- 超出删除老文件 -->
            <totalSizeCap>1GB</totalSizeCap>
        </rollingPolicy>

        <encoder>
            <pattern>${LOG_PATTERN}</pattern>
        </encoder>
    </appender>


    <!--每天生成日志文件，保存30天的日志文件。rollingFile用来切分文件的 -->
    <appender name="rollingFile" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${FILE_PATH}</fileNamePattern>
            <!-- keep 15 days' worth of history -->
            <maxHistory>30</maxHistory>
            <timeBasedFileNamingAndTriggeringPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
                <!-- 日志文件的最大大小 -->
                <maxFileSize>100MB</maxFileSize>
            </timeBasedFileNamingAndTriggeringPolicy>
            <!-- 超出删除老文件 -->
            <totalSizeCap>1GB</totalSizeCap>
        </rollingPolicy>

        <encoder>
            <pattern>${LOG_PATTERN}</pattern>
        </encoder>
    </appender>


    <!-- project default level -->
    <logger name="net.sh.rgface.serive" level="ERROR" />

    <!-- 日志输出级别 -->
    <root level="INFO">
        <appender-ref ref="console" />
        <appender-ref ref="rollingFile" />
        <appender-ref ref="fileErrorLog"/>
    </root>
</configuration>

1.3、配置yml文件

server:
  port: 8080
  tomcat:
    # 该线程池可以容纳的最大线程数。默认值：200；
    maxThreads: 300
    # 最大连接线程数，即：并发处理的最大请求数，默认值为 75
    maxConnections: 3000
    # 允许的最大连接数，应大于等于 maxProcessors ，默认值为 100
    acceptCount: 1000
    # 编码方式
    uri-encoding: UTF-8

spring:
  jackson:
    time-zone: GMT+8
    date-format: yyyy-MM-dd HH:mm:ss
  datasource:
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
#    这里采用的QQ邮箱测试
  mail:
    host: smtp.qq.com
    username: 邮箱
    password: grqpjixakusedicc
    default-encoding: utf-8
application:
  base-package: 基础包名我通常是启动类所在的包

mybatis:
  typeAliasesPackage: ${application.base-package}.pojo, ${application.base-package}.vo, ${application.base-package}.dto
  mapper-locations: classpath:mapper/*/*.xml,classpath:mapper/*.xml
  configuration:
    # 一定要设置，避免个别SQL执行时间过长，把系统搞跨
    default-statement-timeout: 5
    map-underscore-to-camel-case: true
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    cache-enabled: false

#pagehelper分页插件配置
pagehelper:
  helper-dialect: mysql
  reasonable: true
  support-methods-arguments: true
  params: count=countSq

logging:
  config: classpath:logback-spring.xml
