之前使用springMVC+spring+mybatis，总是被一些繁琐的xml配置，有时候如果配置出错，还要检查各种xml配置，偶然接触到了spring boot 后发现搭建一个web项目真的是1分钟的事情，再也不用去管那么多xml配置，简直神清气爽，不用看那么多一坨xml，下面是我把以前的一些ssm项目改成了spring boot + mybatis，相对于来说优点太明显了

1. 创建独立的Spring应用程序

2. 嵌入的Tomcat，无需部署WAR文件

3. 简化Maven配置

4. 自动配置Spring

5. 提供生产就绪型功能，如指标，健康检查和外部配置

6. 绝对没有代码生成和对XML没有要求配置

这个是百度百科上面对spring boot 优点的描述，其实我感觉也是这样，大家可以试一下。

以下是具体的代码实现（github地址：https://github.com/yihec/spring-boot-mybatis）

首先是pom文件的一些依赖

<?xml version="1.0" encoding="UTF-8"?>

     <name>Spring Snapshots</name>
     <url>https://repo.spring.io/snapshot</url>

   <repository>

   </repository>
  </repositories>
  <pluginRepositories>
   <pluginRepository>
     <id>spring-snapshots</id>
     <name>Spring Snapshots</name>
     <url>https://repo.spring.io/snapshot</url>

   <pluginRepository>
     <id>spring-milestones</id>
     <name>Spring Milestones</name>
     <url>https://repo.spring.io/milestone</url>
     <snapshots>
      <enabled>false</enabled>
     </snapshots>
   </pluginRepository>
  </pluginRepositories>
</project>

接着是application.yml数据库配置

spring:
 datasource:
   driver-class-name: oracle.jdbc.OracleDriver 
   url: jdbc:oracle:thin:localhost:1521:orcl
   username: orcl
   password: orcl

然后是application.java

package com.example;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import org.springframework.transaction.PlatformTransactionManager;
import javax.sql.DataSource;
@SpringBootApplication
//@ComponentScan 注解自动收集所有的Spring组件，包括 @Configuration 类。
@ComponentScan
@MapperScan("com.example.mapper")
public class DemoApplication {
  @Bean
  @ConfigurationProperties(prefix="spring.datasource")
  public DataSource dataSource() {
    return new org.apache.tomcat.jdbc.pool.DataSource();
  }
  @Bean
  public SqlSessionFactory sqlSessionFactoryBean() throws Exception {
    SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean();
    sqlSessionFactoryBean.setDataSource(dataSource());
    PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
    //这里的话如果不用mybatis-config.xml 可以把下面那句给注释掉
    sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mybatis/*.xml"));
    sqlSessionFactoryBean.setConfigLocation(resolver.getResource("classpath:mybatis-config.xml"));
    return sqlSessionFactoryBean.getObject();
  }
  @Bean
  public PlatformTransactionManager transactionManager() {
    return new DataSourceTransactionManager(dataSource());
  }
  public static void main(String[] args) {
    SpringApplication.run(DemoApplication.class, args);
  }
}

最后就是swagger的配置了,

package com.example;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
/**
 * Created by lhm on 2015/8/27.
 */
@Configuration
@EnableSwagger2
public class SwaggerConfig
{
  @Bean
  public Docket createRestApi() {
    return new Docket(DocumentationType.SWAGGER_2)
        .apiInfo(apiInfo())
        .select()
        .apis(RequestHandlerSelectors.basePackage("com.example.web"))
        .paths(PathSelectors.any())
        .build();
  }
  private ApiInfo apiInfo() {
    return new ApiInfoBuilder()
        .title("API")
        .description("")
        .termsOfServiceUrl("")
        .contact("yihec")
        .version("1.0")
        .build();
  }
}

最主要的代码就是这些了，然后大功告成，后面的都是个人的业务逻辑了。
