SpringBoot這個(gè)框架我一直比較喜歡，但迫于沒有時(shí)間整理呕乎，一直延續(xù)到現(xiàn)在才來整理框架积担。這個(gè)文章將是一個(gè)系列，從基礎(chǔ)到復(fù)雜猬仁，后面將會(huì)不斷推出系列內(nèi)容帝璧。所有示例都使用Intellij IDEA編寫，項(xiàng)目構(gòu)建方式選擇了Gradle
本篇文章主要介紹持久層湿刽、API文檔的烁、基礎(chǔ)日志的配制。在數(shù)據(jù)持久層上我選擇的是Spring-data-jpa诈闺，使用它非常方便渴庆，可少寫很多代碼，效率也不錯(cuò)雅镊，而且還是spring的親兒子襟雷；api文檔選擇的是Swagger UI2，Swagger可以自動(dòng)生成API文檔仁烹，在文檔界面上還可以測試耸弄，給開發(fā)代來很多方便的；日志這一部分的話就用了比較基礎(chǔ)的東西了晃危，會(huì)把運(yùn)行日志輸出到指定文件中叙赚，方便維護(hù)時(shí)查找問題。
第一步僚饭，創(chuàng)建項(xiàng)目并配制build.gradle文件
通過Intellij IDEA新建一個(gè)Gradle項(xiàng)目震叮，在build.gradle文件中添加項(xiàng)目配制，執(zhí)行一次Refresh all Gradle Projects
apply plugin: 'java'
apply plugin: 'org.springframework.boot'
buildscript {
repositories {
jcenter()
}
dependencies {
classpath("org.springframework.boot:spring-boot-gradle-plugin:1.5.2.RELEASE")
}
}
repositories {
jcenter()
}
dependencies {
compile "org.springframework.boot:spring-boot-starter"
compile 'org.springframework.boot:spring-boot-starter-actuator'
compile 'org.springframework.boot:spring-boot-starter-web'
compile 'org.springframework.boot:spring-boot-starter-data-jpa'
compile 'org.springframework.boot:spring-boot-starter-amqp'
compile 'org.springframework.boot:spring-boot-starter-integration'
compile 'org.springframework.integration:spring-integration-file:4.3.5.RELEASE'
compile 'org.springframework.boot:spring-boot-devtools'
compile 'mysql:mysql-connector-java'
compile 'com.google.code.gson:gson:2.8.0'
compile "io.springfox:springfox-swagger-ui:2.2.2"
compile "io.springfox:springfox-swagger2:2.2.2"
testCompile("org.springframework.boot:spring-boot-starter-test")
}
第二步鳍鸵，創(chuàng)建項(xiàng)目文件目錄
- 創(chuàng)建java文件夾苇瓣，在src文件夾下創(chuàng)建文件夾“/main/java”
- 創(chuàng)建resources文件夾，在src文件夾下創(chuàng)建文件夾“/main/resources”
第三步偿乖，配制application.yml文件
在“src/main/resources/”文件夾下新建文件“application.yml”击罪，并修改其中內(nèi)容哲嘲。
server：服務(wù)器相關(guān)設(shè)定，在這晨設(shè)定了服務(wù)啟動(dòng)后的端口號(hào)和服務(wù)的根地址
spring.datasource：配制系統(tǒng)數(shù)據(jù)源
spring.jpa：設(shè)置jpa的基礎(chǔ)信息
logging：調(diào)協(xié)日志的信息媳禁，logging.file設(shè)置日志文件的存放眠副，可以是“D:\test.logging”這種方式
server:
port: 8081
context-path: /api/
spring:
datasource:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://220.192.001.001:3306/test
username: root
password: 123456
initialSize: 5
minIdle: 5
maxActive: 20
jpa:
hibernate:
ddl-auto: update
naming:
strategy: org.hibernate.cfg.ImprovedNamingStrategy
show-sql: true
database: mysql
logging:
file: springboot.log
第四步，添加Application.java文件
在項(xiàng)目java包中添加Application.java文件竣稽，并初始化內(nèi)容
package leix.lebean.sweb;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;
@SpringBootApplication
public class Application extends SpringBootServletInitializer {
@Autowired
ApplicationContext context;
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
return builder.sources(Application.class);
}
public static void main(String[] args) throws Exception {
SpringApplication.run(Application.class, args);
}
}
到這里所有的配制就完成了囱怕，剩下的就是數(shù)據(jù)層的使用了，下面介紹一上jpa的使用
創(chuàng)建數(shù)據(jù)實(shí)體
package leix.lebean.sweb.model;
import javax.persistence.*;
import java.io.Serializable;
/**
* Name:City
* Description:
* Author:leix
* Time: 2017/3/28 14:02
*/
@Entity
@Table(name = "city")
public class City implements Serializable{
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.IDENTITY)
private int id;
@Column(name = "name")
private String name;
@Column(name = "state")
private String state;
@Column(name = "country")
private String country;
public int getId() {return id;}
public void setId(int id) {this.id = id;}
public String getName() {return name;}
public void setName(String name) { this.name = name;}
public String getState() {return state;}
public void setState(String state) {this.state = state;}
public String getCountry() {return country;}
public void setCountry(String country) {this.country = country;}
}
創(chuàng)建數(shù)據(jù)處理倉庫毫别，jpa的具體語法在這里不詳細(xì)講述了娃弓，后面會(huì)專門寫一篇文章來介紹
package leix.lebean.sweb.repository;
import leix.lebean.sweb.model.City;
import org.springframework.data.jpa.repository.JpaRepository;
/**
* Name:CityRepository
* Description:
* Author:leix
* Time: 2017/3/28 14:13
*/
public interface CityRepository extends JpaRepository<City, Integer> {
City findById(int id);
}
數(shù)據(jù)處理倉庫的調(diào)用
package leix.lebean.sweb.service.impl;
import leix.lebean.sweb.model.City;
import leix.lebean.sweb.repository.CityRepository;
import leix.lebean.sweb.service.CityService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;
@Service
@Transactional
public class CityServiceImpl implements CityService {
@Autowired
CityRepository cityRepository;
@Override
public City findById(int id) {
return cityRepository.findById(id);
}
}
