springboot2 多模塊項目 mybatis的使用

首先建立多模塊項目讓項目成功運行並跑起來

能夠參考文章建立多模塊項目 Go!!!

項目分3個子模塊分別是，父級megatron

1. megatron-api
   項目啓動類

   package com.megatron.module;
   
   import com.megatron.utils.IPUtils;
   import org.mybatis.spring.annotation.MapperScan;
   import org.slf4j.Logger;
   import org.slf4j.LoggerFactory;
   import org.springframework.boot.SpringApplication;
   import org.springframework.boot.autoconfigure.SpringBootApplication;
   
   @SpringBootApplication
   @MapperScan("com.megatron.module.dal.mapper") //掃描指定包中的接口
   public class MegatronLogApiApplication {
   	public static Logger logger = LoggerFactory.getLogger(MegatronLogApiApplication.class);
   	public static void main(String[] args) {
   		System.setProperty("local-ip", IPUtils.getLocalIp());
   		SpringApplication.run(MegatronLogApiApplication.class, args);
   	}
   
   }

   application.yml

   spring:
     datasource:
       name: mysql
       type: com.alibaba.druid.pool.DruidDataSource
       druid:
         filter: stat
         driver-class-name: com.mysql.cj.jdbc.Driver
         url: jdbc:mysql://127.0.0.1:3306/megatron?useUnicode=true&characterEncoding=UTF-8&allowMultiQueries=true
         username: root
         password:
         #配置初始化大小/最小/最大
         initial-size: 1
         min-idle: 1
         max-active: 20
         #獲取鏈接等待超時時間
         max-wait: 60000
         #間隔多久進行一次檢測，檢測須要關閉的空閒鏈接
         time-between-eviction-runs-millis: 60000
         #一個鏈接在池中最小生存的時間
         min-evictable-idle-time-millis: 300000
         validation-query: SELECT 'x'
         test-while-idle: true
         test-on-borrow: false
         test-on-return: false
         #打開PSCache，並指定每一個鏈接上PSCache的大小。oracle設爲true，mysql設爲false。分庫分表較多推薦設置爲false
         pool-prepared-statements: false
         max-pool-prepared-statement-per-connection-size: 20
   logging:
     config: classpath:log4j2-test.yml
   mybatis:
     mapper-locations: classpath:mapper/*.xml
     type-aliases-package: com.megatron.module.dal.entity

   
    

2. megatron-impl
   mybatis須要用到的pom

   <dependency>
       <groupId>org.mybatis</groupId>
       <artifactId>mybatis</artifactId>
       <version>3.5.1</version>
       <scope>compile</scope>
   </dependency>
   
   <dependency>
       <groupId>mysql</groupId>
       <artifactId>mysql-connector-java</artifactId>
       <scope>runtime</scope>
   </dependency>
   
   <!-- 分頁插件 -->
   <dependency>
       <groupId>com.github.pagehelper</groupId>
       <artifactId>pagehelper-spring-boot-starter</artifactId>
       <version>1.2.5</version>
   </dependency>
   <!-- alibaba的druid數據庫鏈接池 -->
   <dependency>
       <groupId>com.alibaba</groupId>
       <artifactId>druid-spring-boot-starter</artifactId>
       <version>1.1.9</version>
   </dependency>

   
   紅框內容是經過mybatis插件生成代碼參考插件Go!!!
