配置文件

新建一个application.yml文件。

# 数据库配置
spring:
  datasource:
    url: jdbc:mysql://localhost:3306/frs?characterEncoding=utf-8
    username: root
    password: 123456
    driver-class-name: com.mysql.cj.jdbc.Driver
# jpa设置
  jpa:
#更新策略
    hibernate:
      ddl-auto: update
    #打印sql语句
    show-sql: true
    #自动生成表结构
    generate-ddl: true

# 启动端口
server:
  port: 8080
  
#mybatis设置
mybatis:
  #映射文件位置
  config-location: classpath:mapper/*.xml
  configuration:
  #日志实现类
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

导入依赖

pom.xml定义如下

springsecurity注意事项

导入springsecurity依赖后，启动项目首页会显示登陆页面。如何关闭有以下几个办法：

方法一：配置关闭登陆验证

package com.cao.frs.configuration;

import org.springframework.security.config.annotation.web.builders.HttpSecurity;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfiguration;
import org.springframework.security.config.annotation.web.configuration.WebSecurityConfigurerAdapter;

public class MySecurityConfig extends WebSecurityConfigurerAdapter {
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        //关闭security的登录验证
        http.formLogin().disable();
    }
}

方法二：在yml配置文件中设置对应的用户名和密码

spring:
  security:
    users:
      name: admin
	  password: admin

如果不设置，用户名为'users ',密码为启动时生成的UUID。
