使用Spring Boot可以更快速的创建一个基于Spring的项目，相比于SpringMVC确实少了很多的配置以及依赖，SpringBoot把相当多的搭建操作都封装起来了，简便有简便的好处，旧的框架搭建流程却也让我们更加明白手上的东西是什么。

项目创建

正常创建一个maven项目，在pom文件加入，注意版本的对应和冲突问题

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.4.2.RELEASE</version>
		<relativePath /> <!-- lookup parent from repository -->
	</parent>
	<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<java.version>1.8</java.version>
	</properties>
	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-test</artifactId>
			<scope>test</scope>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<!-- 如果在使用自带tomcat请注释下面，如果使用第三方tomcat不要注释下面 -->
			<exclusions>
				<exclusion>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-tomcat</artifactId>
				</exclusion>
			</exclusions>
		</dependency>
		<dependency>
			<groupId>javax.servlet</groupId>
			<artifactId>servlet-api</artifactId>
			<version>3.0-alpha-1</version>
		</dependency>
		<dependency>
			<groupId>org.mybatis.spring.boot</groupId>
			<artifactId>mybatis-spring-boot-starter</artifactId>
			<version>1.1.1</version>
		</dependency>
		<dependency>
			<groupId>mysql</groupId>
			<artifactId>mysql-connector-java</artifactId>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-devtools</artifactId>
			<optional>true</optional>
		</dependency>
		<dependency>
			<groupId>org.mybatis</groupId>
			<artifactId>mybatis</artifactId>
			<version>3.4.1</version>
		</dependency>
		<dependency>
			<groupId>com.alibaba</groupId>
			<artifactId>fastjson</artifactId>
			<version>1.2.16</version>
		</dependency>
		<dependency>
			<groupId>org.apache.commons</groupId>
			<artifactId>commons-lang3</artifactId>
			<version>3.4</version>
		</dependency>
	</dependencies>

新建一个Application.java

@SpringBootApplication
//动态扫描DAO所在包
@MapperScan("com.xxx.mapper")
public class Application {
    private static Logger logger = Logger.getLogger(Application.class);

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

    @Override  
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {  
        return application.sources(Application.class);  
    }  
}

然后正常创建Controller，service，dao层，对应的mapper，自定义日志，数据库等配置文件

mybatis-config.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd">
<configuration>
	<typeAliases>
		<typeAlias alias="Integer" type="java.lang.Integer" />
		<typeAlias alias="Long" type="java.lang.Long" />
		<typeAlias alias="HashMap" type="java.util.HashMap" />
		<typeAlias alias="LinkedHashMap" type="java.util.LinkedHashMap" />
		<typeAlias alias="ArrayList" type="java.util.ArrayList" />
		<typeAlias alias="LinkedList" type="java.util.LinkedList" />
	</typeAliases>
</configuration>

application.properties

mybatis.config-locations=classpath:mybatis/mybatis-config.xml
spring.datasource.test1.driverClassName = com.mysql.jdbc.Driver
spring.datasource.test1.url = jdbc:mysql://192.168.1.121:3306/authority?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&useSSL=false
spring.datasource.test1.username = root
spring.datasource.test1.password = pass

自定义interceptor拦截器UserTokneInterceptor，由MyInterceptorConfig配置类加载

@Configuration
public class MyInterceptorConfig extends WebMvcConfigurerAdapter {

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new UserTokneInterceptor()).addPathPatterns("/**").excludePathPatterns("/login");;
        super.addInterceptors(registry);
    }
}

项目主要代码就这么多，最后测试接口情况是否正常即可。
