從零開始完成一個SpringBoot+JPA的學生管理系統Web案例((一)新建項目和配置)

一、創建SpringBoot項目

1. 打開idea File->New->Project

2. 選擇Spring initializr(初始化) ，然後點Next

3. 更改Group和Artifact後，點擊Next

4. 在新頁面中Core中勾選DevTools;Web中勾選Web；Template Engines(模板引擎)勾選 Thymeleaf；SQL中勾選JPA和              MYSQL,然後點Next

5. 最後界面直接點Finish

二、配置SpringBoot項目

1. 在src/main/java 建立以下目錄

2. 編輯pom.xml文件 

pom.xml :

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.1.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.example</groupId>
    <artifactId>springbootdemo</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>springbootdemo</name>
    <description>Demo project for Spring Boot</description>

    <properties>
        <java.version>1.8</java.version>
    </properties>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>

        <!-- druid數據庫連接池-->
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>

        </dependency>

        </dependency>

        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-pool2</artifactId>
            <version>2.4.2</version>
        </dependency>

        <!--springboot操作redis的組件-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-redis</artifactId>
        </dependency>

        <!--添加糊塗工具類-->
        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>4.5.6</version>
        </dependency>

        <!--javamail依賴用來發送電子郵件-->
        <dependency>
            <groupId>javax.mail</groupId>
            <artifactId>mail</artifactId>
            <version>1.4.7</version>
        </dependency>

        <!-- https://mvnrepository.com/artifact/com.github.pagehelper/pagehelper-spring-boot-starter -->
        <dependency>
            <groupId>com.github.pagehelper</groupId>

            <version>1.2.10</version>
        </dependency>

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

3. 編輯src/main/resources/ 下的 application.properties文件

application.properties：

#數據源配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.driverClassName=com.mysql.cj.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/stu?useSSL=false&useUnicode=true&characterEncoding=utf-8&autoReconnect=true&serverTimezone=Asia/Shanghai
spring.datasource.username=root
spring.datasource.password=root    
spring.datasource.initialSize=20
spring.datasource.minIdle=50
spring.datasource.maxActive=500


#上下文配置
server.port=8888
server.servlet.context-path=/kude


#配置jpa
#幫我們自動生成表結構
spring.jpa.properties.hibernate.hbm2ddl.auto=update
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
spring.jpa.show-sql= true

spring.jpa.properties.hibernate.enable_lazy_load_no_trans=true

4. 此時點擊運行測試SpringBoot運行成功

項目搭建和配置完成，接下來編寫後臺代碼，功能實現後再進行測試，請看下一篇：《從零開始完成一個SpringBoot+JPA的Web案例((二)後端實現)》
