准备工作

1、导包

    <dependencies>                <dependency>            <groupId>org.springframework.bootgroupId>            <artifactId>spring-boot-starter-webartifactId>        dependency>                        <dependency>            <groupId>com.baomidougroupId>            <artifactId>mybatis-plus-boot-starterartifactId>            <version>3.5.1version>        dependency>                <dependency>            <groupId>org.mybatis.spring.bootgroupId>            <artifactId>mybatis-spring-boot-starterartifactId>            <version>2.2.2version>        dependency>                <dependency>            <groupId>com.alibabagroupId>            <artifactId>druid-spring-boot-starterartifactId>            <version>1.2.16version>        dependency>                        <dependency>            <groupId>com.alibabagroupId>            <artifactId>druid-spring-boot-starterartifactId>            <version>1.2.11version>        dependency>                <dependency>            <groupId>org.springframework.bootgroupId>            <artifactId>spring-boot-starter-jdbcartifactId>        dependency>                <dependency>            <groupId>mysqlgroupId>            <artifactId>mysql-connector-javaartifactId>            <scope>runtimescope>        dependency>                                <dependency>            <groupId>com.baomidougroupId>            <artifactId>mybatis-plus-generatorartifactId>            <version>3.5.2version>        dependency>                <dependency>            <groupId>org.springframework.bootgroupId>            <artifactId>spring-boot-starter-freemarkerartifactId>        dependency>                <dependency>            <groupId>org.projectlombokgroupId>            <artifactId>lombokartifactId>            <optional>trueoptional>        dependency>        <dependency>            <groupId>org.springframework.bootgroupId>            <artifactId>spring-boot-starter-testartifactId>            <scope>testscope>        dependency>    dependencies>    <build>                <resources>            <resource>                <directory>class="lazy" data-src/main/javadirectory>                <includes>                    <include>***.xmlinclude>                includes>                <filtering>falsefiltering>            resource>            <resource>                <directory>class="lazy" data-src/main/resourcesdirectory>                <includes>                    <include>***.xmlinclude>                includes>                <filtering>falsefiltering>            resource>        resources>                <plugins>            <plugin>                <groupId>org.springframework.bootgroupId>                <artifactId>spring-boot-maven-pluginartifactId>                <configuration>                    <excludes>                        <exclude><groupId>org.projectlombokgroupId><artifactId>lombokartifactId>                        exclude>                    excludes>                configuration>            plugin>        plugins>                <plugins>            <plugin>                <groupId>org.springframework.bootgroupId>                <artifactId>spring-boot-maven-pluginartifactId>                <executions>                    <execution>                        <goals><goal>repackagegoal>                        goals>                    execution>                executions>            plugin>        plugins>        <finalName>项目名finalName>    build>

2、全部的配置文件（配置JDBC、Druid、MP）

spring:  datasource:    driver-class-name: com.mysql.cj.jdbc.Driver    username: root    password: 123456    url: jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf-8&serverTimezone=Asia/Shanghai&useSSL=true&allowMultiQueries=true    # Oracle配置    #url: jdbc:oracle:thin:@127.0.0.1:1521:test    #username: root    #password: 123456    #driver-class-name: oracle.jdbc.driver.OracleDriver    #    配置druid数据源    type: com.alibaba.druid.pool.DruidDataSource    # druid 配置    druid:      #    打开我们的内置监控页面，打开后我们才可以有相应的web界面      stat-view-servlet:        enabled: true        url-pattern: /druid*.propertiesinclude>                    <include>***.propertiesinclude>                    <include>**/*.xmlinclude>                includes>                <filtering>falsefiltering>            resource>        resources>build>
