spring boot 2.x 整合mybaits及分页插件

在众多ORM持久层框架中，凯哥还是比较喜欢使用mybatis。至于mybatis的好处在此就不一一列举了。本篇主要介绍的是在spring boot中怎么整合mybatis及git的分页插件。

整合步骤：

1：pom.xml中添加jar支持

2：配置数据源

3：编写代码测试

一：pom.xml文件中添加jar支持

1.1 parent

<parent>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-parent</artifactId>

<version>2.0.3.RELEASE</version>

<relativePath/> <!-- lookup parent from repository -->

</parent>

1.2 设置编码utf-8

<properties>

<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>

<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>

<java.version>1.8</java.version>

</properties>

1.3 添加依赖

<dependencies>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-web</artifactId>

</dependency>

<dependency>

<groupId>org.mybatis.spring.boot</groupId>

<artifactId>mybatis-spring-boot-starter</artifactId>

<version>1.3.2</version>

</dependency>

<dependency>

<groupId>mysql</groupId>

<artifactId>mysql-connector-java</artifactId>

<scope>runtime</scope>

</dependency>

<dependency>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-starter-test</artifactId>

<scope>test</scope>

</dependency>

<dependency>

<groupId>org.apache.commons</groupId>

<artifactId>commons-lang3</artifactId>

<version>3.4</version>

</dependency>

<dependency>

<groupId>com.fasterxml.jackson.core</groupId>

<artifactId>jackson-core</artifactId>

</dependency>

<dependency>

<groupId>com.fasterxml.jackson.core</groupId>

<artifactId>jackson-databind</artifactId>

</dependency>

<dependency>

<groupId>com.fasterxml.jackson.datatype</groupId>

<artifactId>jackson-datatype-joda</artifactId>

</dependency>

<dependency>

<groupId>com.fasterxml.jackson.module</groupId>

<artifactId>jackson-module-parameter-names</artifactId>

</dependency>

<!-- 分页插件 -->

<dependency>

<groupId>com.github.pagehelper</groupId>

<artifactId>pagehelper-spring-boot-starter</artifactId>

<version>1.2.5</version>

</dependency>

<!-- alibaba的druid数据库连接池 -->

<dependency>

<groupId>com.alibaba</groupId>

<artifactId>druid-spring-boot-starter</artifactId>

<version>1.1.9</version>

</dependency>

<!-- tomcat支持 -->

<dependency>

<groupId>org.apache.tomcat.embed</groupId>

<artifactId>tomcat-embed-jasper</artifactId>

<!--<scope>provided</scope>-->

</dependency>

<!-- jstl标签库 -->

<dependency>

<groupId>javax.servlet</groupId>

<artifactId>jstl</artifactId>

</dependency>

</dependencies>

1.4 添加插件

<build>

<plugins>

<plugin>

<groupId>org.springframework.boot</groupId>

<artifactId>spring-boot-maven-plugin</artifactId>

</plugin>

</plugins>

</build>

二：配置数据源

在yml文件中配置：

2.1：配置数据库相关的

2.2：配置加载mapper位置及扫描pojo包：

2.3：配置分页插件

三：编码测试

3.1：创建测试数据库

CREATE TABLE `t_user` (

`userId` int(11) NOT NULL AUTO_INCREMENT,

`userName` varchar(255) NOT NULL,

`password` varchar(255) NOT NULL,

`phone` varchar(255) NOT NULL,

PRIMARY KEY (`userId`)

) ENGINE=InnoDB AUTO_INCREMENT=1001 DEFAULT CHARSET=utf8;

3.2：创建pojo

3.4：mapper.xml中编写

3.5 service中：

3.6 controller中：

3.7 启动类

3.8使用postman 进行测试

3.8.1：测试新增
