SpringBoot+MyBatis(generator)+druid整合

最近自己写了一个SpringBoot2.0.2+Mybatis（generator）+druid的demo

首先实现的是mybatis和generator逆向工程生成代码

1.pom文件如下，引入generator插件

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

2.在resources下新建generator文件夹，在generator下新建generatorConfig.xml

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

  generatorConfiguration

        PUBLIC   "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"

        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd" >

< generatorConfiguration >

    < context  id ="DB2Tables"    targetRuntime ="MyBatis3" >

        < commentGenerator >

            < property  name ="suppressAllComments"  value ="true" />

        commentGenerator >

       

        < jdbcConnection  driverClass ="com.mysql.jdbc.Driver"  connectionURL ="jdbc:mysql://localhost:3306/wordimg"  userId ="root"  password ="root" >

3.运行generator插件

4.生成如下目录

5.application.yml中的配置 其中包括对druid的配置

spring:

  datasource:

      url: jdbc:mysql://localhost:3306/wordimg?useUnicode=true&characterEncoding=utf-8&useSSL=false

      username: root

      password: root

      driver-class-name: com.mysql.jdbc.Driver

      platform: mysql

      type: com.alibaba.druid.pool.DruidDataSource

      # 下面为连接池的补充设置，应用到上面所有数据源中

      # 初始化大小，最小，最大

      initialSize: 1

      minIdle: 3

      maxActive: 20

      # 配置获取连接等待超时的时间

      maxWait: 60000

      # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒

      timeBetweenEvictionRunsMillis: 60000

      # 配置一个连接在池中最小生存的时间，单位是毫秒

      minEvictableIdleTimeMillis: 30000

      validationQuery: select 'x'

      testWhileIdle: true

      testOnBorrow: false

      testOnReturn: false

      # 打开PSCache，并且指定每个连接上PSCache的大小

      poolPreparedStatements: true

      maxPoolPreparedStatementPerConnectionSize: 20

      # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙

      filters: stat,wall,slf4j

      # 通过connectProperties属性来打开mergeSql功能；慢SQL记录

      connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000

      # 合并多个DruidDataSource的监控数据

      #useGlobalDataSourceStat: true

  jpa:

    show-sql: true

    properties:

      hibernate:

        hbm2ddl:

          auto: create

mybatis:

  mapper-locations: classpath:mapper/*.xml

6.对druid进行配置

        // IP白名单

        servletRegistrationBean.addInitParameter("allow", "192.168.2.25,127.0.0.1");

        // IP黑名单(共同存在时，deny优先于allow)

        servletRegistrationBean.addInitParameter("deny", "192.168.1.100");

        //控制台管理用户

        servletRegistrationBean.addInitParameter("loginUsername", "admin");

        servletRegistrationBean.addInitParameter("loginPassword", "admin");

        //是否能够重置数据 禁用HTML页面上的“Reset All”功能

        servletRegistrationBean.addInitParameter("resetEnable", "false");

        return servletRegistrationBean;

    }

    @Bean

        return filterRegistrationBean;

    }

    //解决 spring.datasource.filters=stat,wall,log4j 无法正常注册进去

7.单元测试

package  com.cnooc.dao;

import  com.cnooc.pojo.TFile;

import  org.junit.Assert;

import  org.junit. Test ;

import  org.junit.runner. RunWith ;

import  org.springframework.beans.factory.annotation. Autowired ;

import  org.springframework.boot.test.context. SpringBootTest ;

import  org.springframework.test.context.junit4.SpringRunner;

import static  org.junit.Assert.*;

/**

 * Created by Administrator on 2018/6/11.

 */

@RunWith (SpringRunner. class )

@SpringBootTest

public class  TFileMapperTest {

    @Autowired

    private  TFileMapper  tFileMapper ;

    @Test

    public void  insert()  throws  Exception {

        TFile tFile =  new  TFile();

        tFile.setId( 7 );

        tFile.setName( "ceshi" );

        tFile.setType( "ppt" );

        tFile.setHaxi( "1111" );

        tFile.setAddress( "cccc" );

        tFile.setCreateTime( "11111" );

        int  a =  tFileMapper .insert(tFile);

        Assert. assertEquals ( 1 ,a);

    }

}

8.对了启动类上别忘了扫描接口类

package  com.cnooc;

import  org.mybatis.spring.annotation. MapperScan ;

import  org.springframework.boot.SpringApplication;

import  org.springframework.boot.autoconfigure. SpringBootApplication ;

@SpringBootApplication

@MapperScan ( "com.cnooc.dao" )

public class  WordimgApplication {

    public static void  main(String[] args) {

      SpringApplication. run (WordimgApplication. class , args);

   }

}
