springboot+vue前后端分离项目（三）后端项目搭建及配置

1. 项目创建

2. 配置pom文件

添加依赖

 <dependency>
     <groupId>com.alibaba</groupId>
     <artifactId>druid-spring-boot-starter</artifactId>
     <version>1.1.10</version>
 </dependency>
 <dependency>
     <groupId>org.projectlombok</groupId>
     <artifactId>lombok</artifactId>
     <version>1.18.12</version>
 </dependency>

3. 配置application.yml文件

server:
  port: 8090
  servlet:
    context-path: /vhr
  address:

spring:
  profiles:
    active: dev
  application:
    name: vhr
  # 数据源配置
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/vhr?useUnicode=true&characterEncoding=utf-8&useSSL=false&autoReconnect=true&serverTimezone=UTC
    type: com.alibaba.druid.pool.DruidDataSource
    data-username: root
    data-password: root
    druid:
      # 初始化大小，最小，最大
      initial-size: 5
      min-idle: 5
      max-active: 20
      # 配置获取连接等待超时的时间
      max-wait: 60000
      # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
      time-between-eviction-runs-millis: 60000
      # 配置一个连接在池中最小生存的时间，单位是毫秒
      min-evictable-idle-time-millis: 300000
      validation-query: SELECT 1 FROM DUAL
      # 申请连接的时候检测，如果空闲时间大于timeBetweenEvictionRunsMillis，执行validationQuery检测连接是否有效。
      test-while-idle: true
      # 申请连接时会执行validationQuery检测连接是否有效,开启会降低性能,默认为true
      test-on-borrow: false
      # 归还连接时会执行validationQuery检测连接是否有效,开启会降低性能,默认为true
      test-on-return: false
      # 打开PSCache，并且指定每个连接上PSCache的大小. 是否缓存preparedStatement,mysql5.5+建议开启
      pool-prepared-statements: true
      # 当值大于0时poolPreparedStatements会自动修改为true
      max-pool-prepared-statement-per-connection-size: 20
      # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙
      filters: stat,wall,slf4j
      # 合并多个DruidDataSource的监控数据
      use-global-data-source-stat: true
      # 通过connectProperties属性来打开mergeSql功能；慢SQL记录
      connect-properties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

mybatis:
  # 注意：一定要对应mapper映射xml文件的所在路径
  mapper-locations: classpath:/mapper/*Dao.xml
  # 注意：对应实体类的路径
  type-aliases-package: com.javaboy.vhr.entity

# 日志配置
logging:
  file:
    path: logs
  level:
    org.springframework: WARN
    com.javaboy.vhr: DEBUG

4. 配置启动类

@Slf4j
@SpringBootApplication
@MapperScan(basePackages = "com.javaboy.vhr.dao")
public class VhrApplication {

    public static void main(String[] args) throws UnknownHostException {
        final HashMap<String, Object> props = new HashMap<>();
        final ConfigurableApplicationContext context = new SpringApplicationBuilder()
                .properties(props)
                .sources(VhrApplication.class)
                .run(args);

        final Environment env = context.getEnvironment();
        VhrApplication.log.info("\n----------------------------------------------------------\n\t" +
                        "Application '{}' is running! ActiveProfiles is '{}', Access URLs:\n\t" +
                        "Local: \t\thttp://127.0.0.1:{}\n\t" +
                        "External: \thttp://{}:{}\n----------------------------------------------------------",
                env.getProperty("spring.application.name"),
                env.getProperty("spring.profiles.active"),
                env.getProperty("server.port"),
                InetAddress.getLocalHost().getHostAddress(),
                env.getProperty("server.port"));
    }

}
