使用IDEA快速搭建SSM+SpringBoot项目

1.创建包

一般项目必不可少的包有、controller（控制器）、mapper（接口）、pojo（实体类）、service（接口的实现类）、util（工具类），注意准守规范，包名全小写！

 resources目录下需创建mapper包，用于与数据库交互

 在main下面创建webapp包，用于放一些资源文件，如static、WEB-INF中的jsp、lib等等

---

2.配置SpringBoot启动类

代码如下：

package com.apollo.apollodemo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.ServletComponentScan;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;

/**
 * SpringBoot启动类
 */
@SpringBootApplication
@ServletComponentScan
@MapperScan("com.apollo.apollodemo.mapper") //@MapperScan 用户扫描MyBatis的Mapper接口
public class Apollo extends SpringBootServletInitializer {
    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Apollo.class);
    }

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

}

3.pom文件导入常用的包（这里需要配置好Maven仓库）

4.项目全局配置文件application.properties（这里也可以改成其它格式的文件）

#配置端口号
server.port=88

#配置MYSQL数据库
spring.datasource.driverClassName=com.mysql.jdbc.Driver
spring.datasource.url=jdbc:mysql://数据库链接/数据库名称?characterEncoding=utf-8&useSSL=false&allowMultiQueries=true
spring.datasource.username=******
spring.datasource.password=******
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource

#配置控制器返回路径
spring.mvc.view.prefix=/WEB-INF/jsp/
spring.mvc.view.suffix=.jsp
mybatis.type-aliases-package=com.apollo.appllodemo.pojo
mybatis.mapper-locations=classpath:mapper/*.xml

#配置时间格式
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
spring.jackson.serialization.write-dates-as-timestamps=false

#配置日志文件
logging.level.com.muen.mapper=debug
