maven创建springboot项目

• 创建maven项目，pom.xml文件如下：

<?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">

    <!--声明项目描述符遵循哪一个POM模型版本。模型本身的版本很少改变，虽然如此，但它仍然是必不可少的，这是为了当Maven引入了新的特性或者其他模型变更的时候，确保稳定性。-->
    <modelVersion>4.0.0</modelVersion>
    <!--父项目的坐标。如果项目中没有规定某个元素的值，那么父项目中的对应值即为项目的默认值。 坐标包括group ID，artifact ID和 version。-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.2.RELEASE</version>
        <!-- 父项目的pom.xml文件的相对路径。相对路径允许你选择一个不同的路径。默认值是../pom.xml。Maven首先在构建当前项目的地方寻找父项目的pom，
             其次在文件系统的这个位置（relativePath位置），然后在本地仓库，最后在远程仓库寻找父项目的pom。-->
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <!--项目坐标-->

• 启动配置文件application.yml配置：

server:
  port: 8080
spring:
  datasource:
    url: jdbc:oracle:thin:@127.0.0.1:1521:orcl
    username: system
    password: abc123
  jackson:
    date-format: yyyy-MM-dd HH:mm:ss
    time-zone: GMT+8
mybatis:
  type-aliases-package: com.link.dto
  mapper-locations: classpath:/mapper/*.xml
  #configuration:
    #log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

• 日志文件logback.xml配置：

<configuration scan="true" scanPeriod="60 seconds" debug="false">
    <property name="context_name" value="boot-template" />
    <property name="log.path" value="./logs" />
    <contextName>${context_name}</contextName>

    <!--输出到控制台-->
    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} %line - %msg%n</pattern>
        </encoder>
    </appender>

    <!--输出到文件-->
    <appender name="file" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <fileNamePattern>${log.path}/logback.%d{yyyy-MM-dd}.log</fileNamePattern>

        <encoder>
            <pattern>%d{HH:mm:ss.SSS} %contextName [%thread] %-5level %logger{36} - %msg%n</pattern>
        </encoder>
    </appender>
    <!--配置包路径com.link.mapper下mapper的日志输出-->
    <logger name="com.link.mapper" level="DEBUG"  additivity="false">
        <appender-ref ref="console"/>
    </logger>

    <root level="info">
        <appender-ref ref="console" />
        <appender-ref ref="file" />
    </root>
</configuration>

• 启动类：

package com.link;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.EnableAspectJAutoProxy;
import org.springframework.scheduling.annotation.EnableScheduling;
import org.springframework.scheduling.annotation.Scheduled;

import java.time.LocalDateTime;
import java.time.format.DateTimeFormatter;

@SpringBootApplication
@EnableScheduling
@EnableAspectJAutoProxy
@MapperScan(basePackages = {"com.link.mapper"})
public class Application {
    public static void main(String[] args) {
        SpringApplication.run(Application.class);
    }

    @Scheduled(cron = "0/60 * * * * ?")
    public void test(){

        System.out.println(LocalDateTime.now().format(DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss"))+ " Scheduled ...");
    }
}
