Spring Boot 整合mybatis 与 swagger2

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：） 

首先是pom文件的一些依赖

<?xml version="1.0" encoding="utf-8"?>
<project xmlns="http://maven.apache.org/pom/4.0.0" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance"

     <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。
