springboot: mybatis逆向工程
第一步： pom文件配置 黄线的部分是所要配置的
<?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.payease</groupId> <artifactId>sell</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>sell</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.8.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- ===================== mysql驱动 ======================== --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- ===================== jpa ======================== --> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-jpa</artifactId> </dependency> <!-- ===================== @Getter @Setter @Slf4j @Data ======================== --> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> </dependency> <!-- ===================== google: gson ======================== --> <dependency> <groupId>com.google.code.gson</groupId> <artifactId>gson</artifactId> </dependency> <!-- https://mvnrepository.com/artifact/com.alibaba/fastjson --> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>1.2.36</version> </dependency> <!-- https://mvnrepository.com/artifact/com.github.binarywang/weixin-java-mp --> <dependency> <groupId>com.github.binarywang</groupId> <artifactId>weixin-java-mp</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-freemarker</artifactId> </dependency> <dependency> <groupId>cn.springboot</groupId> <artifactId>best-pay-sdk</artifactId> <version>1.1.0</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-websocket</artifactId> </dependency> <!--<!– ===================== mybatis ======================== –>--> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-starter</artifactId> <version>1.3.0</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.2</version> <dependencies> <dependency> <groupId> mysql</groupId> <artifactId> mysql-connector-java</artifactId> <version>5.1.27</version> </dependency> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> </dependencies> <executions> <execution> <id>Generate MyBatis Artifacts</id> <phase>package</phase> <goals> <goal>generate</goal> </goals> </execution> </executions> <configuration> <!--允许移动生成的文件 --> <verbose>true</verbose> <!-- 是否覆盖 --> <overwrite>false</overwrite> <!-- 自动生成的配置 --> <configurationFile> src/main/resources/mybatis-generator.xml</configurationFile> </configuration> </plugin> </plugins> </build> </project>
第二步：在resource文件夹下创建 mybatis-generator.xml 文件
<?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> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true"/> </commentGenerator> <!--数据库链接地址账号密码--> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://rm-uf6qe0894f7hv8977o.mysql.rds.aliyuncs.com/sell" userId="root" password="liuxiaoming_123" > </jdbcConnection> <javaTypeResolver> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!--生成Model类存放位置--> <javaModelGenerator targetPackage="com.payease.dataobject" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!--生成映射文件存放位置--> <sqlMapGenerator targetPackage="com.payease.dataobject.mapper" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!--生成Dao类存放位置--> <!-- 客户端代码，生成易于使用的针对Model对象和XML配置文件 的代码 type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象 type="MIXEDMAPPER",生成基于注解的Java Model 和相应的Mapper对象 type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.payease.dataobject.dao" targetProject="src/main/java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!--生成对应表及类名--> <table tableName="product_category" domainObjectName="ProductCategory"> <!-- enableCountByExample="false" enableUpdateByExample="false" enableDeleteByExample="false" enableSelectByExample="false" selectByExampleQueryId="false"--> <generatedKey column="id" sqlStatement="JDBC" identity="true"/> </table> </context> </generatorConfiguration>
第三步：双击mybatis-generator:generate
第五步：在src/main/java/com/payease/ 文件夹下的 dataobject 、dataobject/dao 、dataobject/mapper生成相应的文件
注：springboot 默认的mapper.xml映射文件扫描的位置在 resources/mapper文件夹下
若不在此文件夹下，请在pom文件中进行相应的配置
<build> <resources> <resource> <directory>src/main/java</directory> <includes> <include>**/*.properties</include> <include>**/*.xml</include> </includes> </resource> </resources> <finalName>wallet-orm</finalName> </build>
