spring boot搭建流程(基于gradle)

网上看到很多spring boot入门文章,但大多不全面,一般只记录简单的创建流程,鉴于此,记录下搭建基于gradle的spring boot项目的一个详细步骤及配置,包括mybatis和日志配置、调试、发布等。本人刚开始尝试记录一些自己的学习过程,文笔和表达能力有限,望大家包含和支持!

系统及项目要求

1.jdk1.8
2.项目构建工具:gradle
3.开发工具:idea
4.spring boot2.0

项目创建过程

  • 根据图示创建项目

    步骤3
  • 一直点击next, 直到点击 finish
  • gradle设置

  • 目录结构

修改配置

  • 修改目录结构(controller/service等包自行添加)

  • 修改gradle配置文件,引入新的依赖

buildscript {
    ext {
        springBootVersion = '2.0.0.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.springboot'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}

// 移除spring boot自带的日志管理工具,否则会有冲突
configurations {
    compile.exclude module: 'spring-boot-starter-logging'
}

dependencies {
    compile('org.springframework.boot:spring-boot-starter-jdbc')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2')
    compile('org.springframework.boot:spring-boot-starter-log4j2')
    compile("com.alibaba:druid:1.1.0")
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}
  • 修改启动文件 BootstudyApplication.java
package com.springboot.bootstudy;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.servlet.ServletComponentScan;

// TODO 自动扫描的包,请根据实际的包结构修改
@SpringBootApplication(scanBasePackages = {
        "com.springboot.bootstudy"
})
// TODO mybatis扫描的mapper接口文件,请根据实际的包结构修改
@MapperScan(basePackages = {
        "com.springboot.bootstudy.mybatis.mapper"
})
// 扫描servlet注解(如果代码中含有servlet相关注解,需要加上此的注解)
@ServletComponentScan
public class BootstudyApplication {

    public static void main(String[] args) {
        SpringApplication.run(BootstudyApplication.class, args);
    }
}
  • 修改yml配置文件(application-daily.yml)
# 设置端口
server:
  port: 8080
spring:
  # 设置数据源,注意命名
  datasource:
    name:
    url: jdbc:mysql://10.0.10.41:3306/shinemo_open?autoReconnect=true&failOverReadOnly=false&maxReconnects=10&characterEncoding=UTF8
    username: root
    password: shinemo123
    type: com.alibaba.druid.pool.DruidDataSource
    driver-class-name: com.mysql.jdbc.Driver
    filters: stat
    connectionProperties: druid.stat.slowSqlMillis=50
    max-active: 5
    initialSize: 1
    maxWait: 60000
    minIdle: 1
    timeBetweenEvictionRunsMillis: 60000
    minEvictableIdleTimeMillis: 300000
    validationQuery: select 'x'
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    poolPreparedStatements: true
    maxOpenPreparedStatements: 20
  # 设置环境
  profiles:
    active: daily

# mybatis 配置xml文件路径和实体包路径
mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com.springboot.bootstudy.mybatis.domain.model

# 设置日志文件路径
logging:
  config: classpath:log4j2-daily.xml

application-online.yml参考上面修改

  • log4j.xml 配置文件


    
        /tmp/logs/bootstudy
        warn
    
    
    
    
    
        
            
                %d{HH:mm:ss,SSS} %-5level [%t] %c{1.}.%M(%L) - %m%n
            
            
                
                
            
            
            
        

        
            
                %d{HH:mm:ss} - %m%n
            
            
                
            
            
        

    

    
    
    
    
        
            
        

        
            
        

        
            
        

    

  • 打印访问日志的filter
package com.springboot.bootstudy.filter;

/**
 * Created by yuanjian on 3/19/18
 *
 * @author [email protected]
 */

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.stereotype.Component;
import org.springframework.web.filter.OncePerRequestFilter;
import org.springframework.web.util.ContentCachingRequestWrapper;
import org.springframework.web.util.ContentCachingResponseWrapper;

import javax.servlet.FilterChain;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.nio.charset.StandardCharsets;

/**
 * 打印日志的filter
 * Created by yuanjian on 3/15/18
 *
 * @author [email protected]
 */
@Component
public class LogFilter extends OncePerRequestFilter {
    private Logger logger = LoggerFactory.getLogger("access.log");
    @Override
    public void destroy() {

    }

    @Override
    protected void doFilterInternal(HttpServletRequest request,
                                    HttpServletResponse response,
                                    FilterChain chain) throws ServletException, IOException {
        int length = request.getContentLength();
        ContentCachingRequestWrapper requestWrapper = new ContentCachingRequestWrapper(request, length);
        ContentCachingResponseWrapper responseWrapper = new ContentCachingResponseWrapper(response);
        try {
            chain.doFilter(request, responseWrapper);
        } finally {
            log(requestWrapper, responseWrapper);
            // 将返回值复制到response中,此段代码必须
            responseWrapper.copyBodyToResponse();
        }
    }
    /**
     * 打印访问日志,可以根据需求定制化
     *
     * @param requestWrapper  保存了body参数的request
     * @param responseWrapper 保存了返回值的response
     */
    private void log(ContentCachingRequestWrapper requestWrapper, ContentCachingResponseWrapper responseWrapper) {
        // 打印日志
        String body = "";
        if (requestWrapper.getContentLength() > 0) {
            body = new String(requestWrapper.getContentAsByteArray(), StandardCharsets.UTF_8);
        }
        byte[] resultByte = responseWrapper.getContentAsByteArray();
        String result = "";
        if (resultByte != null && resultByte.length > 0) {
            result = new String(resultByte, StandardCharsets.UTF_8);
        }
        logger.info("body:{}, result:{}", body, result);
    }
}

接下来我们就可以开发spring boot的应用程序了。
