之前使用springMVC+spring+mybatis，總是被一些繁瑣的xml配置，有時候如果配置出錯，還要檢查各種xml配置，偶然接觸到了spring boot 后發(fā)現(xiàn)搭建一個web項目真的是1分鐘的事情，再也不用去管那么多xml配置，簡直神清氣爽，不用看那么多一坨xml，下面是我把以前的一些ssm項目改成了spring boot + mybatis，相對于來說優(yōu)點太明顯了

1. 創(chuàng)建獨立的Spring應(yīng)用程序

2. 嵌入的Tomcat，無需部署WAR文件

3. 簡化Maven配置

4. 自動配置Spring

5. 提供生產(chǎn)就緒型功能，如指標(biāo)，健康檢查和外部配置

6. 絕對沒有代碼生成和對XML沒有要求配置

這個是百度百科上面對spring boot 優(yōu)點的描述，其實我感覺也是這樣，大家可以試一下。

以下是具體的代碼實現(xiàn)（github地址：https://github.com/yihec/spring-boot-mybatis）

首先是pom文件的一些依賴

</project>

接著是application.yml數(shù)據(jù)庫配置

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 注解自動收集所有的Spring組件，包括 @Configuration 類。
@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();
    //這里的話如果不用mybatis-config.xml 可以把下面那句給注釋掉
    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();
  }
}

最主要的代碼就是這些了，然后大功告成，后面的都是個人的業(yè)務(wù)邏輯了。
