springBoot集成Mybatis generator

1、引入jar包

       <!--boot整合mybatis的包 -->
        <dependency>
            <groupId>org.mybatis.spring.boot</groupId>
            <artifactId>mybatis-spring-boot-starter</artifactId>
            <version>1.1.1</version>
        </dependency>
        <!--mybatis代碼生成器jar包 -->
        <dependency>
            <groupId>org.mybatis.generator</groupId>
            <artifactId>mybatis-generator-core</artifactId>
            <version>1.3.7</version>
        </dependency>
        <!--postgresql 數據庫鏈接器 -->
        <dependency>
            <groupId>org.postgresql</groupId>
            <artifactId>postgresql</artifactId>
            <version>42.2.5</version>
        </dependency>

 

2、引入generator插件

     <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
            <!-- mybatis generator 自動生成代碼插件 -->
            <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>

3、修改屬性文件

#社區
spring.datasource.commonunity.driver-class-name=org.postgresql.Driver
spring.datasource.commonunity.url=jdbc:postgresql://****:5432/test_***
spring.datasource.commonunity.username=**
spring.datasource.commonunity.password=**


#generator
generator.location=C:/maven/pushData/org/postgresql/postgresql/42.2.5/postgresql-42.2.5.jar

 

4、引入 generatorConfig.xml

<?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>
    <!-- 引入 properties 配置文件 -->
    <properties resource="application.properties"/>
    <!-- 數據庫連接驅動包 -->
    <classPathEntry location="${generator.location}" />
    <context id="MySqlTables" targetRuntime="MyBatis3">
        <!-- 生成的Java文件的編碼 -->
        <property name="javaFileEncoding" value="UTF-8" />
        <!-- 格式化java代碼 -->
        <property name="javaFormatter" value="org.mybatis.generator.api.dom.DefaultJavaFormatter" />
        <!-- 格式化XML代碼 -->
        <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter" />
        <!-- 爲生成的Java模型類添加序列化接口 -->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin" />
        <!-- 爲生成的Java模型建立一個toString方法 -->
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin" />
        <!-- 取消註釋 -->
        <commentGenerator>
            <property name="suppressDate" value="true"/>
            <property name="suppressAllComments" value="false" />
        </commentGenerator>
        <jdbcConnection driverClass="${spring.datasource.commonunity.driver-class-name}" connectionURL="${spring.datasource.commonunity.url}" userId="${spring.datasource.commonunity.username}" password="${spring.datasource.commonunity.password}" />
        <!-- java類型處理器 用於處理DB中的類型到Java中的類型，默認使用JavaTypeResolverDefaultImpl； 注意一點，默認會先嚐試使用Integer，Long，Short等來對應DECIMAL和 NUMERIC數據類型； -->
        <javaTypeResolver>
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <javaModelGenerator targetPackage="com.ryj.test.multipleDataSource.entity" targetProject="src/main/java">
            <property name="enableSubPackages" value="false" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <sqlMapGenerator targetPackage="mybatis" targetProject="src/main/resources/mapper">
            <property name="enableSubPackages" value="false" />
        </sqlMapGenerator>
        <javaClientGenerator targetPackage="com.ryj.test.multipleDataSource.dao" targetProject="src/main/java" type="XMLMAPPER">
            <property name="enableSubPackages" value="false" />
        </javaClientGenerator>
        <!-- 生成表而且不生成example -->
        <table schema="" tableName="blacklist_lib"  enableCountByExample="false" enableDeleteByExample="false" enableSelectByExample="false"
               enableUpdateByExample="false" />
    </context>
</generatorConfiguration>

5、exclipse啓動 生成代碼

右鍵點擊項目名->run as ->maven build, 在main->goals 輸入 mybatis-generator:generate

 

生成結果以下圖所示：
