spring boot整合mybatis+mybatis-plus

篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了spring boot整合mybatis+mybatis-plus相关的知识,希望对你有一定的参考价值。

Spring boot对于我来说是一个刚接触的新东西,学习过程中,发现这东西还是很容易上手的,Spring boot没配置时会默认使用Spring data jpa,这东西可以说一个极简洁的工具,可是我还是比较喜欢用mybatis,工具是没有最好的,只有这合适自己的。

说到mybatis,最近有一个很好用的工具--------mybatis-Plus(官网),现在更新的版本是2.1.2,这里使用的也是这个版本。我比较喜欢的功能是代码生成器,条件构造器,这样就可以更容易的去开发了。

mybatisPlus官网上是有Spring boot整个的例子的,我也跟着它走了一篇,结果,程序没跑起来,后来才知道demo用的H2 database,和mysql根本不是同一样东西,所以各位想要整合mybatisPlus,可以不看官网的,可以少走弯路。

下面就是整合的过程

1、首先要把需要的jar文件都弄过来,pom.xml需要的东西如下

pom.xml(不完整)

复制代码
<!-- mybatis-plus begin -->
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatisplus-spring-boot-starter</artifactId>
    <version>1.0.4</version>
</dependency>
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus</artifactId>
    <version>2.1.2</version>
</dependency>
<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>
<!-- mybatis-plus end -->
<!-- druid阿里巴巴数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.1.3</version> </dependency>
<!--mysql-->
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<scope>runtime</scope>
</dependency>
<dependency>
<groupId>org.mybatis.spring.boot</groupId>
<artifactId>mybatis-spring-boot-starter</artifactId>
<version>1.3.1</version>
</dependency>
复制代码

2、添加mybatis相关的配置,如账号、密码等。这里我使用了application.yml来配。

application.yml

复制代码
server:
    port: 8080

spring

spring:
devtools:
restart:
enabled: true #这里是为了热部署的,与mybatis是无关的

DATABASE CONFIG

datasource:
driver-class-name: com.mysql.jdbc.Driver
username: root
password: root
url: jdbc:mysql:
//mysqldb:3306/tdx_shop?useUnicode=true&characterEncoding=utf-8
type: com.alibaba.druid.pool.DruidDataSource #这里是配置druid连接池,以下都是druid的配置信息
filters: stat,wall,log4j
maxActive:
20
initialSize:
1
maxWait:
60000
minIdle:
1
timeBetweenEvictionRunsMillis:
60000
minEvictableIdleTimeMillis:
300000
validationQuery: select
\'x\'
testWhileIdle:
true
testOnBorrow:
false
testOnReturn:
false
poolPreparedStatements:
true
maxOpenPreparedStatements:
20
connection
-properties: druid.stat.merggSql=ture;druid.stat.slowSqlMillis=5000

mybatis

mybatis:
mapper-locations: classpath:/mapper/**Mapper.xml #把xml文件放在com.XX.mapper.中可能会出现找到的问题,这里把他放在resource下的mapper中

实体扫描,多个package用逗号或者分号分隔

typeAliasesPackage: com.tdx.account_service.entity #这里是实体类的位置
configuration:
map-underscore-to-camel-case: true
cache-enabled: false

logging

logging:
level: warn

复制代码

 

配置的东西和我们以前用mybatis配置可以说差不多,但spring boot是没有xml配置文件的。注意一下红字的内容,基本没问题了。

3、mybatis-Plus配置文件------MybatisPlusConfig,首先上图说明一下文件路径。其中MybatisPlusConfig是放在config文件夹内,而xml文件是放在resouces下mapper中。

接着就是MybatisPlusConfig内容部分了

这里是完整的配置文件,需要注意的是引入的包,别引错了!

4、还要开启dao的扫描,很简单,就是在启动文件中添加@MapperScan("com.tdx.account_service.dao*"),如下是完整的

到这里,配置算是完成了,运行一下项目是可以运行起来的。

我觉得Mybatis-Plus最好玩得应该是代码生成器这部分内容,下面是代码生成器的使用过程

pom.xml上要加点东西

<dependency>
    <groupId>org.apache.velocity</groupId>
    <artifactId>velocity-engine-core</artifactId>
    <version>2.0</version>
</dependency>

1、代码生成器的配置文件

文件中修改的内容还是很多的,最主要的还是mysql的连接信息,没理由你账号,密码都错了还能连得上吧,其次设置一下你生成的模板文件路径,我这里生成的路径在上面图可以看得到,是在com.tdx.account_service下的,注意,xml文件要放在resources下,不然是识别的,说找不到这个方法

按照官网的代码模板生成的文件基本是白白的,主要是mybatis-Plus集成了公共方法,很多常用的工具都可以引用了。在这里我提供一下我修改后Controller.java.vm文件,主要还是按照我自己的习惯去弄的

controller.java.vm

复制代码
