凯哥java 凯哥java
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
查询：
得到我们预期的结果。说明sprong boot 2.x整合mybatis及分页插件成功
