SpringCloud学习心得（七） Springboot与Mabatis集成

继续上一节的项目，复制上一节的quartz项目，改名为quartz-mybatis

pom文件如下：

配置文件：

spring:
application:
    name: ceo-eureka-client-test
# datasource:
#    driver-class-name: com.mysql.jdbc.Driver
#    url: jdbc:mysql://127.0.0.1/bpm?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
#    username: root
#    password: 123

server:
port: 8642

eureka:
client:
    serviceUrl:
      defaultZone: http://localhost:8601/eureka/

#datasource config
jdbc:
driverClassName: com.mysql.jdbc.Driver
url: jdbc:mysql://127.0.0.1/bpm?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
username: root
password: 123

#mybatis config
mybatis:
typeAliasesPackage: com.hotkidceo.springcloud.domain
mapperLocations: classpath:mapper/*.xml

新建config包，并建立MyBatisConfig类

package com.hotkidceo.springcloud.config;

import java.util.Properties;

import javax.sql.DataSource;

import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionFactoryBean;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;

import com.alibaba.druid.pool.DruidDataSourceFactory;

@Configuration
@MapperScan(basePackages="com.hotkidceo.springcloud.dao")
public class MyBatisConfig {

   @Autowired
   private Environment env;

   /**
   * @Title: getDataSource
   * @Description: 创建数据源
   * @param @return    设定文件
   * @return DataSource    返回类型
   * @throws
   */
   @Bean
   public DataSource getDataSource(){
       Properties props = new Properties();
        props.put("driverClass", env.getProperty("jdbc.driverClassName"));
        props.put("url", env.getProperty("jdbc.url"));
        props.put("username", env.getProperty("jdbc.username"));
        props.put("password", env.getProperty("jdbc.password"));
        try {
            return DruidDataSourceFactory.createDataSource(props);
        } catch (Exception e) {
            e.printStackTrace();
        }
        return null;
   }

   public SqlSessionFactory sqlSessionFactory(DataSource ds) throws Exception{
       SqlSessionFactoryBean sfb = new SqlSessionFactoryBean();
        sfb.setDataSource(ds);
        //下边两句仅仅用于*.xml文件，如果整个持久层操作不需要使用到xml文件的话（只用注解就可以搞定），则不加
        sfb.setTypeAliasesPackage(env.getProperty("mybatis.typeAliasesPackage"));
        sfb.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(env.getProperty("mybatis.mapperLocations")));
        return sfb.getObject();
   }
}

然后就是建立表、实体类、服务层和控制层，这里就省略了，大家自己尝试一下就好
