## 一、Spring版本管理依赖 ##

*  有这个可以避免很多依赖版本不匹配的问题

<parent>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-parent</artifactId>
            <version>2.3.1.RELEASE</version>
            <relativePath/> 
        </parent>

## 二、SpringBoot启动需要的依赖 ##

*  启动依赖

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-autoconfigure</artifactId>
            </dependency>

*  测试启动依赖

<dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>

## 三、数据库连接的依赖 ##

*  数据库连接驱动

<dependency>
                <groupId>mysql</groupId>
                <artifactId>mysql-connector-java</artifactId>
            </dependency>

*  mybatis-plus的依赖

<dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-boot-starter</artifactId>
                <version> 3.4.0</version>
            </dependency>
            <dependency>
                <groupId>com.baomidou</groupId>
                <artifactId>mybatis-plus-annotation</artifactId>
                <version> 3.4.0</version>
            </dependency>

*  tk\_mybatis的依赖

<dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper-spring-boot-starter</artifactId>
            <version>2.1.5</version>
        </dependency>
    
        <dependency>
            <groupId>tk.mybatis</groupId>
            <artifactId>mapper</artifactId>
            <version>4.1.5</version>
        </dependency>

*  这几个mybatis会冲突，在依赖中使用下面这段代码即可

<exclusions>
                    <exclusion>
                        <groupId>org.mybatis</groupId>
                        <artifactId>mybatis</artifactId>
                    </exclusion>
                    <exclusion>
                        <groupId>org.mybatis</groupId>
                        <artifactId>mybatis-spring</artifactId>
                    </exclusion>
                </exclusions>

## 四、SpringCloud系列常用依赖 ##

*  Eureka（服务注册与发现）

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
    </dependency>

*  Ribbon（客户端负载均衡）：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-ribbon</artifactId>
    </dependency>

*  Feign（声明式服务调用）：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
    </dependency>

*  Hystrix（服务容错保护）：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-hystrix</artifactId>
    </dependency>

*  Zuul（API 网关）：

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
    </dependency>

## 五、实体类常用依赖 ##

*  lombok
    
        <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <version>1.18.8</version>
        </dependency>

## 作者写的Demo ##

## 其他 ##

*  SpringBoot启动类
    
        package com.example.user;
        
        import org.springframework.boot.SpringApplication;
        import org.springframework.boot.autoconfigure.SpringBootApplication;
        
        @SpringBootApplication
        public class UserApplication {
              
        
            public static void main(String[] args) {
              
                SpringApplication.run(UserApplication.class, args);
            }
        
        }
