二、SpringBoot集成Myabtis

2.1. pom 依賴

<!--版本控制-><properties><java.version>1.8</java.version><oracle.version>11.2.0.3</oracle.version><mysql.version>8.0.20</mysql.version></properties><!--Mybatis--><dependency><groupId>org.mybatis.spring.boot</groupId><artifactId>mybatis-spring-boot-starter</artifactId><version>2.1.2</version></dependency><!--Mysql--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency><!--oracle--><dependency><groupId>com.oracle</groupId><artifactId>ojdbc6</artifactId><version>${oracle.version}</version></dependency>

注：數(shù)據(jù)庫任選其一即可

2.2. yml配置

mybatis:configuration:map-underscore-to-camel-case: true# 控制臺日志配置log-impl: org.apache.ibatis.logging.stdout.StdOutImplmapper-locations: classpath:mappers/*.xml

2.3. 啟動類+掃描mapper包注解

package com.gblfy;import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication;@SpringBootApplication @MapperScan(basePackages = "com.gblfy.mapper") public class DemoApplication {public static void main(String[] args) {SpringApplication.run(DemoApplication.class, args);} }

三、集成Mybatis Generator

適配Mysql和Oracle

3.1. 插件集成

官網(wǎng)鏈接：https://mybatis.org/generator/running/runningWithMaven.html

<build><plugins><!--逆向工程--><plugin><groupId>org.mybatis.generator</groupId><artifactId>mybatis-generator-maven-plugin</artifactId><version>1.3.2</version><configuration><verbose>true</verbose><!--代碼生成重新覆蓋--><overwrite>true</overwrite></configuration><dependencies><!--oracle--><dependency><groupId>com.oracle</groupId><artifactId>ojdbc6</artifactId><version>${oracle.version}</version></dependency><!--Mysql--><dependency><groupId>mysql</groupId><artifactId>mysql-connector-java</artifactId><version>${mysql.version}</version></dependency></dependencies></plugin></plugins></build>

3.2. 新建generatorConfig.xml文件

在resources目錄下面
內(nèi)容如下：

<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfigurationPUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN""http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"><generatorConfiguration><context id="testTables" targetRuntime="MyBatis3"><commentGenerator><!-- 是否去除自動生成的注釋 true：是 ： false:否 --><property name="suppressAllComments" value="true" /></commentGenerator><!--數(shù)據(jù)庫連接的信息：驅(qū)動類、連接地址、用戶名、密碼 --><!-- <jdbcConnection driverClass="com.mysql.jdbc.Driver"connectionURL="jdbc:mysql://localhost:3306/knowledge_base?autoReconnect=true&amp;useUnicode=true&amp;characterEncoding=utf8&amp;zeroDateTimeBehavior=CONVERT_TO_NULL&amp;useSSL=false&amp;serverTimezone=CTT&amp;nullCatalogMeansCurrent=true" userId="root"password="root"></jdbcConnection>--><!-- 數(shù)據(jù)庫連接配置 --><jdbcConnection driverClass="oracle.jdbc.driver.OracleDriver"connectionURL="jdbc:oracle:thin:@192.168.0.12:1521:orcl"userId="scoptt"password="scoptt"></jdbcConnection><!-- 默認(rèn)false，把JDBC DECIMAL 和 NUMERIC 類型解析為 Integer，為 true時把JDBC DECIMAL 和NUMERIC 類型解析為java.math.BigDecimal --><javaTypeResolver><property name="forceBigDecimals" value="false" /></javaTypeResolver><!-- targetProject:生成PO類的位置 --><javaModelGenerator targetPackage="com.gblfy.mall.pojo"targetProject="src/main/java"><!-- enableSubPackages:是否讓schema作為包的后綴 --><property name="enableSubPackages" value="false" /><!-- 從數(shù)據(jù)庫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.gblfy.mall.mapper"targetProject="src/main/java"><!-- enableSubPackages:是否讓schema作為包的后綴 --><property name="enableSubPackages" value="false" /></sqlMapGenerator><!-- targetPackage：mapper接口生成的位置 --><javaClientGenerator type="XMLMAPPER"targetPackage="com.gblfy.mall.dao"targetProject="src/main/java"><!-- enableSubPackages:是否讓schema作為包的后綴 --><property name="enableSubPackages" value="false" /></javaClientGenerator><!-- 指定數(shù)據(jù)庫表 --><!--<table schema="" tableName="MQ_PRODUCER_LOG_TRACK"></table>--><table schema="" tableName="sys_user"></table><!-- 有些表的字段需要指定java類型<table schema="" tableName=""><columnOverride column="" javaType="" /></table> --></context> </generatorConfiguration>

注：Mybatis Generator 配置詳解

3.3.運行插件生成代碼

或者載命令行執(zhí)行以下命令：

mvn mybatis-generator:generate
