IDEA构建Maven+springboot+mybatis+Swagger项目配置及mybatis代码自动生成

配置文件说明
pom.xml --Maven配置及管理
generatorConfig.properties --数据库链接配置
application.properties --mybaits 数据库配置主要用于代码生成等可指定端口 server.port
generatorConfig.xml --mybaits 配置主要反射和用于代码生成等,有人喜欢用.yml

1、pom.xml

                <includes>

2、generatorConfig.properties --数据库链接配置

driver=com.mysql.jdbc.Driver
url=jdbc:mysql://localhost:3306/bdms?useUnicode=true&characterEncoding=UTF-8
username=root
password=123456

3、application.properties --mybaits 数据库配置主要用于代码生成等可指定端口 server.port

#必须
spring.datasource.url=jdbc:mysql://localhost:3306/bdms?useUnicode=true&characterEncoding=UTF-8&useSSL=true
spring.datasource.username=root
spring.datasource.password=123456
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

#mybatis扫描
#必须要写全路径，否则扫描不到文件
#mybatis.mapper-locations=classpath*:mapper/*.xml
mybatis.mapper-locations=classpath:com/boot/mapper/*Mapper.xml
mybatis.typeAliasesPackage=com.boot.model
#html启动文件
spring.mvc.view.prefix=classpath:/templates/
spring.mvc.view.suffix=.html
spring.freemarker.checkTemplateLocation=false

#spring.resources.static-locations=classpath:/templates #指定可以扫描到.html
server.port=9004 #指定端口

4、generatorConfig.xml（有人喜欢用.yml） --mybaits 配置主要反射和用于代码生成等

<?xml version="1.0" encoding="UTF-8"?>

        NUMERIC 类型解析为java.math.BigDecimal -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- targetProject:生成PO类的位置 -->
        <javaModelGenerator targetPackage="com.boot.model"
                            targetProject=".\src\main\java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
            <!-- 从数据库返回的值被清理前后的空格 -->
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- targetProject:mapper映射文件生成的位置 -->
        <sqlMapGenerator targetPackage="com.boot.mapper"
                         targetProject=".\src\main\java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <!-- targetPackage：mapper接口生成的位置 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="com.boot.dao"
                             targetProject=".\src\main\java">
            <!-- enableSubPackages:是否让schema作为包的后缀 -->
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 指定数据库表 -->
        <!--<table schema="" tableName="tb_content"></table>-->
        <table tableName="User" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false" />
    </context>
</generatorConfiguration>

5、mybaits 代码生成

在这里插入图片描述双击即可自动生成，若为生成请检查以上相关配置是否正确
