整合mybatis+generator自動生成程式碼

如何整合Springboot和Mybatis框架，然後使用generator自動生成mapper，pojo等檔案。
1新建sprongBoot專案後pom中引入需要的檔案
資料庫連線驅動、mybatisPlus(已包含mybatis)、generator、注意（bulider中配置generator外掛）
<?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 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test</groupId> <artifactId>BootShiroTest</artifactId> <packaging>pom</packaging> <version>1.0-SNAPSHOT</version> <modules><!--子模組引入--> <module>spring-boot-common</module> <module>spring-boot-shiro</module> </modules> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.0.1.RELEASE</version> </parent> <properties> <druid.version>1.1.10</druid.version> <mysql.version>5.1.38</mysql.version> <mssql.version>4.0</mssql.version> <oracle.version>11.2.0.3</oracle.version> <mybatisplus.version>2.1.9</mybatisplus.version> <mybatisplus.spring.boot.version>1.0.5</mybatisplus.spring.boot.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!-- mysql驅動 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <!-- oracle驅動 --> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>${oracle.version}</version> </dependency> <!-- mssql驅動 --> <dependency> <groupId>com.microsoft.sqlserver</groupId> <artifactId>sqljdbc4</artifactId> <version>${mssql.version}</version> </dependency> <!-- postgresql驅動 --> <dependency> <groupId>org.postgresql</groupId> <artifactId>postgresql</artifactId> </dependency> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>${druid.version}</version> </dependency> <!--mybatis plus--> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus</artifactId> <version>${mybatisplus.version}</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatisplus-spring-boot-starter</artifactId> <version>${mybatisplus.spring.boot.version}</version> </dependency> <!-- log4j. --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-log4j</artifactId> <version>1.3.8.RELEASE</version> </dependency> <!-- mybatis程式碼自動生成工具--> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.5</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <!-- mybatis generator 自動生成程式碼外掛 --> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <configuration> <configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile> <overwrite>true</overwrite> <verbose>true</verbose> </configuration> </plugin> </plugins> </build> </project>
2配置application.properties檔案 （根據需要！）
spring.datasource.url= jdbc:mysql://localhost:3306/test?useUnicode=true&characterEncoding=utf8 spring.datasource.username=root spring.datasource.password=root spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.type=com.alibaba.druid.pool.DruidDataSource #spring.datasource.schema=database/import.sql spring.thymeleaf.cache=false spring.thymeleaf.mode=LEGACYHTML5 spring.jpa.database=mysql mybatis.mapper-locations=classpath:mapping/*.xml # LOG4J配置 log4j.rootCategory=INFO,stdout,file # 日誌輸出到檔案 log4j.appender.file=org.apache.log4j.DailyRollingFileAppender log4j.appender.file.file=logs/springboot.log log4j.appender.file.DatePattern='.'yyyy-MM-dd log4j.appender.file.layout=org.apache.log4j.PatternLayout log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %5p %c{1}:%L - %m%n
3配置generator自動生成程式碼：檔案放置的位置就在pom.xml檔案裡面一如外掛的位置${basedir}/src/main/resources/generator/generatorConfig.xml
注意（裡面的jar路徑、包路徑、專案路徑 表配置都不要寫錯）
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!-- 資料庫驅動:選擇你的本地硬碟上面的資料庫驅動包--> <classPathEntry location="G:\JAVA\Repository\mysql\mysql-connector-java\5.1.40\mysql-connector-java-5.1.40.jar"/> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <!-- 是否去除自動生成的註釋 true：是 ： false:否 --> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--資料庫連結URL，使用者名稱、密碼 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://localhost/test_spboot" userId="root" password="123456"> </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!-- 生成模型的包名和位置--> <javaModelGenerator targetPackage="com.jy.entity" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- 生成對映檔案的包名和位置--> <sqlMapGenerator targetPackage="mapping" targetProject="src/main/resources"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!-- 生成DAO的包名和位置--> <javaClientGenerator type="XMLMAPPER" targetPackage="com.jy.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!-- 要生成的表 tableName是資料庫中的表名或檢視名 domainObjectName是實體類名--> <table tableName="resources" domainObjectName="Resources" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="role" domainObjectName="Role" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="role_resources" domainObjectName="RoleResources" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="user" domainObjectName="User" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> <table tableName="user_role" domainObjectName="UserRole" enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"></table> </context> </generatorConfiguration>
6建立好資料庫後執行
