Spring Boot 項目搭建

1.pom.xml配置

    <artifactId>R_security</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>war</packaging>

    <description>Demo project for Spring Boot</description>

    <!-- spring boot 必須 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.3.RELEASE</version>
        <relativePath /> <!-- lookup parent from repository -->
    </parent>

    <!-- 設置資源編碼 -->
    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
    </properties>

2.application.properties文件

server.port=8080
#server.servlet-path=*.html

#logging.level.org.springframework=DEBUG
logging.level.org.springframework=INFO

#DataSource
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://localhost:3306/test?zeroDateTimeBehavior=convertToNull&useUnicode=true&characterEncoding=utf-8&useSSL=true
spring.datasource.username=root
spring.datasource.password=*******

#jpa
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=update

3.程序入口類 MainApplication.java

必須放在Controller類同級或上級目錄下

只有在啓動類同級或下級目錄下才會被掃描註解

代碼：

/**
 * 程序入口類
 * 
 * @author Zeke_Red
 * @version 1.0.0
 */
@SpringBootApplication
public class MainApplication {

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

4.其他業務代碼不贅述.

注：MainApplication.java 以 Java Application 運行，即可把項目跑起來

訪問路徑：http://localhost:8080/ 不用加項目名
