Gradle配置MybatisGenerator逆向工程

Gradle配置MybatisGenerator逆向工程

​ 之前一直都是用的maven的方式做的，由于公司现在用的是Gradle构建工程，所以也是在网上找了一下方案，大家可以参考一下我的方式，这里附上Gradle的插件官网，大家可以去官网搜索想要的插件

• Gradle插件官网： Gradle - Plugins

1.首先在buid.gradle文件里面导入相关的jar包和MybatisGenerator的插件

​ buid.gradle可以理解成maven的pom.mxl，这里需要注意的是gradle是2.1之前的比较久的版本跟2.1之后的新的版本导入插件的方式不一样，这一点gradle的插件官网是有说明的

• 2.1之前的版本

buildscript {
    ext {
        springBootVersion = '2.0.1.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.jarry'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2')
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test')

    //数据库
    compile group: 'org.apache.tomcat', name: 'tomcat-jdbc', version: '8.5.23'
    //日志
    compile group: 'log4j', name: 'log4j', version: '1.2.17'
    //fastjson
    compile group: 'com.alibaba', name: 'fastjson', version: '1.2.47'


}

//mybatis generator plugin ------ start
buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "gradle.plugin.com.arenagod.gradle:mybatis-generator-plugin:1.4"
    }
}

apply plugin: "com.arenagod.gradle.MybatisGenerator"

configurations {
    mybatisGenerator
}

mybatisGenerator {
    verbose = true
    configFile = 'src/main/resources/tools/generatorConfig.xml'
}
//mybatis generator plugin ------ end

• 2.1之后的版本

buildscript {
    ext {
        springBootVersion = '2.0.1.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = 'com.jarry'
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8

repositories {
    mavenCentral()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2')
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test')

    //数据库
    compile group: 'org.apache.tomcat', name: 'tomcat-jdbc', version: '8.5.23'
    //日志
    compile group: 'log4j', name: 'log4j', version: '1.2.17'
    //fastjson
    compile group: 'com.alibaba', name: 'fastjson', version: '1.2.47'


}

//mybatis generator plugin ------ start
plugins {
  id "com.arenagod.gradle.MybatisGenerator" version "1.4"
}

apply plugin: "com.arenagod.gradle.MybatisGenerator"

configurations {
    mybatisGenerator
}

mybatisGenerator {
    verbose = true
    configFile = 'src/main/resources/tools/generatorConfig.xml'
}
//mybatis generator plugin ------ end

2.在resources目录下新建config.properties文件配置数据库链接信息和要生成的 Java 类的包

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.168.1.11:3306/ssmDemo?characterEncoding=utf8
jdbc.username=root
jdbc.password=111111


# 生成实体类所在的包
package.model=org.zn.user.entity
# 生成 mapper 类所在的包
package.mapper=org.zn.user.dao
# 生成 mapper xml 文件所在的包，默认存储在 resources 目录下
package.xml=mapping
# 表名
package.tableName=user
# 生成实体类名称
package.entityName=User

3.在resources目录下新建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>
    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <commentGenerator>
            <property name="suppressAllComments" value="true"></property>
            <property name="suppressDate" value="true"></property>
            <property name="javaFileEncoding" value="utf-8"/>
        </commentGenerator>

        <jdbcConnection driverClass="${driverClass}"
                        connectionURL="${connectionURL}"
                        userId="${userId}"
                        password="${password}">
        </jdbcConnection>

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

        <javaModelGenerator targetPackage="${modelPackage}" targetProject="${src_main_java}">
            <property name="enableSubPackages" value="true"></property>
            <property name="trimStrings" value="true"></property>
        </javaModelGenerator>

        <sqlMapGenerator targetPackage="${sqlMapperPackage}" targetProject="${src_main_resources}">
            <property name="enableSubPackages" value="true"></property>
        </sqlMapGenerator>

        <!-- type="ANNOTATEDMAPPER",生成Java Model 和基于注解的Mapper对象
             type="MIXEDMAPPER",生成基于注解的JavaModel 和相应的Mapper对象
             type="XMLMAPPER",生成SQLMap XML文件和独立的Mapper接口  -->
        <javaClientGenerator targetPackage="${mapperPackage}" targetProject="${src_main_java}" type="XMLMAPPER">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- 这种方式是所有的表逆向生成类 下面是单个表具体看情况使用
        <table tableName="%">
            <generatedKey column="epa_id" sqlStatement="Mysql" identity="true" />
        </table> -->


        <!-- 要生成的表 tableName是数据库中的表名或视图名 domainObjectName是实体类名-->
        <table tableName="${tableName}" domainObjectName="${entityName}"
               enableCountByExample="false" enableUpdateByExample="false"
               enableDeleteByExample="false" enableSelectByExample="false"
               selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

4.刷新Gradle工程，在对应模块的other找到mbGenerator双击运行生成文件
