前言：

本文主要讲解连接sqlserver的配置

一：所需依赖：

<?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 https://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.4.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>
    <groupId>com.dmdd</groupId>
    <artifactId>yifang</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>yifang</name>
    <description>yifang</description>
    <properties>
        <java.version>8</java.version>
    </properties>
    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter</artifactId>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-boot-starter</artifactId>
            <version>3.5.3</version>
        </dependency>
        <dependency>
            <groupId>com.baomidou</groupId>
            <artifactId>mybatis-plus-generator</artifactId>
            <version>3.5.3</version>
        </dependency>
        <dependency>
            <groupId>com.microsoft.sqlserver</groupId>
            <artifactId>sqljdbc4</artifactId>
            <scope>system</scope>
            <version>4.0</version>
            <systemPath>${project.basedir}/src/main/java/com/lib/sqljdbc4-4.0.jar</systemPath>
        </dependency>

<!--        &lt;!&ndash; https://mvnrepository.com/artifact/com.microsoft.sqlserver/sqljdbc4 &ndash;&gt;-->
<!--        <dependency>-->
<!--            <groupId>com.microsoft.sqlserver</groupId>-->
<!--            <artifactId>sqljdbc4</artifactId>-->
<!--            <version>4.0</version>-->
<!--        </dependency>-->

    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

注：引用sqlserver比mysql多了如下依赖，并且跟mybatis plus的版本一致
<dependency>
    <groupId>com.baomidou</groupId>
    <artifactId>mybatis-plus-generator</artifactId>
    <version>3.5.3</version>
</dependency> 

注：SqlServer连接所需依赖需要以jar包的形式引入

<dependency>
    <groupId>com.microsoft.sqlserver</groupId>
    <artifactId>sqljdbc4</artifactId>
    <scope>system</scope>
    <version>4.0</version>
    <systemPath>${project.basedir}/src/main/java/com/lib/sqljdbc4-4.0.jar</systemPath>
</dependency>

二：application.yml

server:
  port: 8099
  #    配置数据源
spring:
  datasource:
    driver-class-name: com.microsoft.sqlserver.jdbc.SQLServerDriver
    url: jdbc:sqlserver://localhost:1433;databaseName=HLDB_Dev_012
    username: sa
    password: jly720609
#    开启驼峰命名的实体类
mybatis-plus:
  configuration:
    map-underscore-to-camel-case: true

    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: com/hl/hlkj/entity

三:分页插件

package com.dmdd.yifang.config;

import com.baomidou.mybatisplus.annotation.DbType;
import com.baomidou.mybatisplus.autoconfigure.ConfigurationCustomizer;
import com.baomidou.mybatisplus.extension.plugins.MybatisPlusInterceptor;
import com.baomidou.mybatisplus.extension.plugins.inner.PaginationInnerInterceptor;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration
//@MapperScan("scan.your.mapper.package")
public class MybatisPlusConfig {

    /**
     * 新的分页插件,一缓和二缓遵循mybatis的规则,需要设置 MybatisConfiguration#useDeprecatedExecutor = false 避免缓存出现问题(该属性会在旧插件移除后一同移除)
     */
    @Bean
    public MybatisPlusInterceptor mybatisPlusInterceptor() {
        MybatisPlusInterceptor interceptor = new MybatisPlusInterceptor();
        interceptor.addInnerInterceptor(new PaginationInnerInterceptor(DbType.SQL_SERVER2005));
        return interceptor;
    }


}
