Spring Boot 环境配置

在Spring Boot中，可以通过编写主程序类来启动应用。在该类上使用@SpringBootApplication注解标注说明这是一个Spring Boot应用。具体的例子如下所示:

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

此外，根据引用中的内容，可以在项目的pom.xml文件中配置相关的依赖项。例如，可以添加spring-boot-starter-web依赖项来启用web功能。具体的pom.xml配置如下所示:

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
</parent>
<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
</dependencies>

在Spring Boot应用中，还可以通过yml文件来配置环境。例如，可以在resources目录下创建一个名为application.yml的文件，并在其中配置端口号、上下文路径、数据源等信息。具体的配置如下所示:

server:
  port: 8989
  servlet:
    context-path: /mvc

spring:
  datasource:
    type: com.mchange.v2.c3p0.ComboPooledDataSource
    driver-class-name: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://127.0.0.1:3306/hr
    username: root
    password: root

freemarker:
  suffix: .ftl
  content-type: text/html
  charset: UTF-8
  template-loader-path: classpath:/views/

devtools:
  restart:
    enabled: true
  additional-paths: src/main/java
  poll-interval: 3000
  quiet-period: 1000

cache:
  ehcache:
    config: classpath:ehcache.xml

mybatis:
  mapper-locations: classpath:/mappers/*.xml
  type-aliases-package: com.xxxx.springboot.po
  configuration:
    map-underscore-to-camel-case: true

pagehelper:
  helper-dialect: mysql

logging:
  level:
    com.xxxx.dao: debug

最后，根据引用中的内容，还可以在项目中编写SQL映射文件来配置相关的数据库操作。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
