maven创建mybatis****

引入mybatis依赖

<dependency>
	<groupId>org.mybatis.spring.boot</groupId>
	 <artifactId>mybatis-spring-boot-starter</artifactId>
	 <version>2.0.0</version>
</dependency>

添加mybatis generator依赖

• configurationFile标签里填写配置文件xml的路径

<plugin>
     <groupId>org.mybatis.generator</groupId>
     <artifactId>mybatis-generator-maven-plugin</artifactId>
     <version>1.3.2</version>
     <configuration>
         <configurationFile>src/main/resources/mybatis.xml</configurationFile>
         <verbose>true</verbose>
         <overwrite>true</overwrite>
     </configuration>
     <executions>
         <execution>
             <id>Generate MyBatis Artifacts</id>
             <goals>
                 <goal>generate</goal>
             </goals>
         </execution>
     </executions>
     <dependencies>
         <dependency>
             <groupId>org.mybatis.generator</groupId>
             <artifactId>mybatis-generator-core</artifactId>
             <version>1.3.2</version>
         </dependency>
     </dependencies>
 </plugin>

添加配置文件mybatis.xml

• 配置文件模板如下：

<?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>
    <classPathEntry location="C:\maven\repository\mysql\mysql-connector-java\5.1.35\mysql-connector-java-5.1.35.jar"  />

    <context id="mysqlTables" targetRuntime="MyBatis3">
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin">
            <property name="useToStringFromRoot" value="true" />
        </plugin>

        <commentGenerator>
            <!--关闭自动生成注释-->
            <property name="suppressAllComments" value="true" />
            <property name="suppressDefaultComments" value="true" />
            <property name="dateFormat" value="yyyy-MM-dd HH:mm:ss"/>
        </commentGenerator>

        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc:mysql://127.0.0.1:3306/mytodo?characterEncoding=utf8"
                        userId="root"
                        password="123456">
        </jdbcConnection>

        <javaTypeResolver >
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>

        <javaModelGenerator targetPackage="com.jie.service.entity" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="mapper" targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="com.jie.service.dao" targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <table tableName="test" domainObjectName="test" enableSelectByExample="false"
               enableDeleteByExample="false" enableCountByExample="false" enableUpdateByExample="false" selectByExampleQueryId="false">
            <generatedKey column="id" sqlStatement="MYSQL" identity="true" />
            <!--<columnOverride column="status" javaType="java.lang.Integer" jdbcType="TINYINT"/>-->
        </table>
    </context>
</generatorConfiguration>
