gradle整合mybatis generator

准备工作

工具

Intellij IDEA

gradle 2.1+

mysql 5.6

新增测试表

DROP TABLE IF EXISTS `test`;
CREATE TABLE `test` (
 `id` VARCHAR (32) NOT NULL COMMENT 'id',
 `number` int (11) NOT NULL COMMENT 'int',
 `t_number` tinyint (2) NOT NULL DEFAULT 1 COMMENT 'tinyint',
 `b_str` text COMMENT 'text',
 PRIMARY KEY `id` (`id`)
) ENGINE = INNODB DEFAULT CHARSET = utf8 COMMENT = '测试表';

修改build.gradle

//plugins 的上面只允许 buildscript{} 和 plugins{} 两种
plugins {
    id "com.arenagod.gradle.MybatisGenerator" version "1.4" //gradle提供的mybatis generator插件
}

group 'gradle'
version '1.0-SNAPSHOT'

apply plugin: 'java'

sourceCompatibility = 1.8

configurations {
    mybatisGenerator
}

mybatisGenerator {
    verbose = true
    configFile = 'src/main/resources/generatorConfig.xml'
}

repositories {
    maven {
        url 'http://maven.aliyun.com/nexus/content/groups/public'
    }
}

dependencies {
    compile 'mysql:mysql-connector-java:5.1.6'
}

在src/main/resources下新增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="mybatis" targetRuntime="MyBatis3">
        <!-- 数据库信息 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="jdbc.url"
                        userId="jdbc.username"
                        password="jdbc.password">
        </jdbcConnection>

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

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

        <sqlMapGenerator targetPackage="com.test.mapper"  targetProject="src/main/java">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>

        <javaClientGenerator type="XMLMAPPER" targetPackage="com.test.mapper"  targetProject="src/main/resources">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>

        <!-- 表名 -->
        <table tableName="test" domainObjectName="Test" ></table>

    </context>
</generatorConfiguration>

点击右侧Gradle，依次选择generator->Tasks->other->mbGenerator运行

说一句

笔者在这里仅提供了gradle配置mybatis generator的方法，其实mybatis generator不仅仅只可以通过gradle配置，还可以通过maven，java等多样的配置方式，而这些官网上均有详尽的说明，读者朋友完全可以按照官网的说明，自行配置，笔者在这里就不一一赘述了。
