基于spring boot 的ssm项目的简单配置

我前面的帖子有介绍spring boot的简单搭建，如今我再讲讲spring boot的简单配置

首先，项目结构

启动类

@RestController    注解至关于@ResponseBody ＋ @Controller合在一块儿的做用。
@SpringBootApplication     项目建立默认的注解，解释的话有点多直接贴网址你们本身进去了解   https://blog.csdn.net/dyangel2013/article/details/79775122    
@EnableAutoConfiguration     详细的本身去了解一下   https://blog.csdn.net/zxc123e/article/details/80222967

package com.example;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

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

pojo包下不须要什么注解

我却是了解到如今能够加入

@Getter
@Setter
@ToString

能够让你省略掉冗余的get  set 方法和toString方法

 

mapper包下是接口和mapper文件

接口依然不须要什么注解，mapper文件中须要注意的有一点

1中是对应的接口位置

2中对应pojo实体类

service包下的结构

接口依然没有什么注解，service的实现类须要加入@service注解

也能够加上@Transactional事务处理的注解，事务处理在启动类也能够用另外一个注解加入

 

这是application.properties里的配置

spring.datasource.url=jdbc:mysql://localhost:3306/mpms
spring.datasource.username=root
spring.datasource.password=123
spring.datasource.driver-class-name=com.mysql.jdbc.Driver
spring.jpa.database=mysql

最后就是pom文件了，固然pom文件确定不是最后才配置的，我只是放在最后说

不少注解我也不是很深刻的理解，目前只能说是可以运用，你们多多谅解不能详细给你们解释
