SpringBoots的使用

1.如果使用maven工程直接配置pox.xml文件自动下载jar包和依赖的包

<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">
    <modelVersion>4.0.0</modelVersion>
    <groupId>com.xdl</groupId>
    <artifactId>springboot1.o</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <packaging>war</packaging>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.6.RELEASE</version>
    </parent>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
            <version>1.5.6.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.30</version>
        </dependency>
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.2.1</version>
        </dependency>
    </dependencies>
    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin </artifactId>
            </plugin>
        </plugins>
    </build>
</project>

或者自己导入jar包

2.创建springboot启动类和main方法

package com.xdl.server;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.web.servlet.config.annotation.ContentNegotiationConfigurer;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
//扫描springmvc的controller
@ComponentScan(basePackages = { "com.xdl.controller", "com.xdl.service" })
//扫描mybatis部分的道接口和mapper方法
@MapperScan(basePackages = { "com.xdl.dao" })
//自动加载所有需要的bean
@EnableAutoConfiguration
public class MainServer extends WebMvcConfigurerAdapter {

    @Override
    public void configureContentNegotiation(
            ContentNegotiationConfigurer configurer) {
        configurer.favorPathExtension(false);
    }

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