方式1：完全采用配置
2：配置+代码configuration

一、完全采用配置：

pom文件依赖


<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <!-- Spring Boot 启动父依赖 -->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>1.5.1.RELEASE</version>
    </parent>

    <groupId>com.mes.cloud</groupId>
    <artifactId>mes-cloud-starter</artifactId>
    <package>jar</package>
    <properties>
        <java.version>1.8</java.version>
    </properties>

    <version>1.0-SNAPSHOT</version>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Camden.SR5</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
             <!-- Spring Boot Web 依赖 -->
            <dependency>
                  <groupId>org.springframework.boot</groupId>
                  <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <!-- Spring Boot Mybatis 依赖 -->
            <dependency>
                <groupId>org.mybatis.spring.boot</groupId>
                <artifactId>mybatis-spring-boot-starter</artifactId>
                <version>1.3.1</version>
            </dependency>
            <!-- 分页插件 -->
            <dependency>
                <groupId>com.github.pagehelper</groupId>
                <artifactId>pagehelper</artifactId>
                <version>5.1.0</version>
            </dependency>
            <!-- springboot对mybatis的整合支持还是比较苛刻的，版本不兼容问题比较严重，pageHelper分页插件也是一样，不是最新的版本就没有问题，有时需要降低版本进行支持，这里的版本是调试通过可以用的版本，其他应该还有可以匹配的版本，但是没有去测试 --> 
            <!-- spring boot pagehelper autoconfigure依赖 版本有兼容性问题 第一种方式依赖的包-->  
            <dependency>
                <groupId>com.github.pagehelper</groupId>
                <artifactId>pagehelper-spring-boot-autoconfigure</artifactId>
                <version>1.1.1</version>
            </dependency>
            <!-- spring boot 整合pagehelper依赖 版本有兼容性问题 第一种方式依赖的包-->  
            <dependency>
                <groupId>com.github.pagehelper</groupId>
                <artifactId>pagehelper-spring-boot-starter</artifactId>
                <version>1.2.3</version>
            </dependency>
        </dependencies>
</project>

application.yml文件配置

#mybatis配置 第一种和第二种需要 第三种不需要
mybatis:
  #mapper.xml文件位置
  mapper-locations: classpath*:mapper/*.xml
  check-config-location: true
  #对应mapper的实体类
  type-aliases-package: com.mes.cloud.**.dto

#pagehelper分页配置 第二种和第三种不需要 重点讲的第一种需要
pagehelper:
    helperDialect: mysql
    reasonable: true
    supportMethodsArguments: true
    params: count=countSql

二、基于java类配置

pom相关依赖

java配置类

@Configuration
public class MyBatisPlusConfig {


    @Bean
    public PaginationInterceptor paginationInterceptor() {
        PaginationInterceptor page  = new PaginationInterceptor();
        page.setDialectType("mysql");
        return page ;
    }

}
