springboot mybatis逆向工程配置mysql

使用工具：JDK1.8、IntelliJ IDEA、mysql

1. pom.xml文件 mybatis相关依赖和插件添加
   

   <dependency>
      <groupId>org.mybatis.spring.boot</groupId>
      <artifactId>mybatis-spring-boot-starter</artifactId>
      <version>1.3.2</version>

         <!--<scope>runtime</scope>-->
      </dependency>
      <dependency>

                   </dependency>
               </dependencies>
           </plugin>
       </plugins>
   </build>

   
   
2. generatorConfig.xml配置

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

  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
   <!--<classPathEntry
         location="D:\soft\mysql-connector-java-5.0.8.jar"/>-->
   <context id="testTables" targetRuntime="MyBatis3">
      <commentGenerator>
         <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
         <property name="suppressAllComments" value="true" />
      </commentGenerator>
      <!--数据库连接的信息：驱动类、连接地址、用户名、密码 -->
      <jdbcConnection driverClass="com.mysql.jdbc.Driver"
         connectionURL="jdbc:mysql://localhost:3306/test" userId="root"
         password="pxmwcwj">
      </jdbcConnection>
      <!-- <jdbcConnection driverClass="oracle.jdbc.OracleDriver" connectionURL="jdbc:oracle:thin:@127.0.0.1:1521:yycg" 
         userId="yycg" password="yycg"> </jdbcConnection> -->

      <!-- 默认false，把JDBC DECIMAL 和 NUMERIC 类型解析为 Integer，为 true时把JDBC DECIMAL 
         和 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.yonyou.demo.domain"
         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.yonyou.demo.mapper"
         targetProject="./src/main/java">
         <!-- enableSubPackages:是否让schema作为包的后缀 -->
         <property name="enableSubPackages" value="false" />
      </sqlMapGenerator>
      <!-- 生成DAO的包名和位置-->
      <javaClientGenerator type="XMLMAPPER"
         targetPackage="com.yonyou.demo.mapper" 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 tableName="idp_project_info"></table>
   </context>
</generatorConfiguration>

3.application.yml（数据源配置）配置

spring:
  application:
    name: demoservice
  profiles:
    active: dev
  datasource:
          name: test
          url: jdbc:mysql://127.0.0.1:3306;DatabaseName=test
          username: root
          password: pxmwcwj
          # 使用druid数据源
          type: com.alibaba.druid.pool.DruidDataSource
          driver-class-name: com.mysql.jdbc.Driver
          filters: stat
          maxActive: 20
          initialSize: 1
          maxWait: 60000
          minIdle: 1
          timeBetweenEvictionRunsMillis: 60000
          minEvictableIdleTimeMillis: 300000
          validationQuery: select 'x'
          testWhileIdle: true
          testOnBorrow: false
          testOnReturn: false
          poolPreparedStatements: true
          maxOpenPreparedStatements: 20
mybatis:
  mapper-locations: classpath:mapper/*.xml
  type-aliases-package: cn.com.cgnpc.bizcenter.filecenter.model
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl

#pagehelper分页插件
pagehelper:
    helperDialect: sqlserver
    reasonable: true
    supportMethodsArguments: true
    pageSizeZero: true
    params: count=countSql

4.运行
