gradel MyBatis Generator [ant]

1.指定数据库连接信息、和生成entity及dao所在位置配置

src/main/resources/mybatis/config.properties

# JDBC
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://192.*.*.*:*/*?useUnicode=true&characterEncoding=utf-8&useSSL=false
jdbc.username=root
jdbc.password=*

# 生成实体类所在的包
package.model=com.scm.huaqin.codepush.entity
# 生成 mapper 类所在的包
package.mapper=com.scm.huaqin.codepush.dao
# 生成 mapper xml 文件所在的包，默认存储在 resources 目录下
package.xml=mybatis/mapper

2.生成使用XML、指定生成方式（那些表等、具体参照官方http://www.mybatis.org/generator/configreference/xmlconfig.html）

src/main/resources/mybatis/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>

        <javaClientGenerator targetPackage="${mapperPackage}" targetProject="${src_main_java}" type="ANNOTATEDMAPPER">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- sql占位符，表示所有的表 -->
        <table tableName="%">
        </table>
    </context>
</generatorConfiguration>

3.在build.gradle中编写ant的task

build.gradle

//配置mybatisGenerator在dependencies中使用
configurations {
    mybatisGenerator
}
//引入依赖
dependencies {
    compile('org.springframework.boot:spring-boot-starter-actuator')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.3.2')
    compile('org.springframework.cloud:spring-cloud-starter')
    runtime('org.springframework.boot:spring-boot-devtools')
    runtime('mysql:mysql-connector-java')
    testCompile('org.springframework.boot:spring-boot-starter-test')

    mybatisGenerator 'org.mybatis.generator:mybatis-generator-core:1.3.2'
    mybatisGenerator 'mysql:mysql-connector-java:5.1.36'
    mybatisGenerator 'tk.mybatis:mapper:3.3.2'
}
//读取配置、在task中调用
def getDbProperties = {
    def properties = new Properties()
    file("src/main/resources/mybatis/config.properties").withInputStream { inputStream ->
        properties.load(inputStream)
    }
    properties
}
//调用入口
task mybatisGenerate << {
    def properties = getDbProperties()
    ant.properties['targetProject'] = projectDir.path
    ant.properties['driverClass'] = properties.getProperty("jdbc.driverClassName")
    ant.properties['connectionURL'] = properties.getProperty("jdbc.url")
    ant.properties['userId'] = properties.getProperty("jdbc.username")
    ant.properties['password'] = properties.getProperty("jdbc.password")
    ant.properties['src_main_java'] = sourceSets.main.java.srcDirs[0].path
    ant.properties['src_main_resources'] = sourceSets.main.resources.srcDirs[0].path
    ant.properties['modelPackage'] = properties.getProperty("package.model")
    ant.properties['mapperPackage'] = properties.getProperty("package.mapper")
    ant.properties['sqlMapperPackage'] = properties.getProperty("package.xml")

    ant.taskdef(
            name: 'mbgenerator',
            classname: 'org.mybatis.generator.ant.GeneratorAntTask',
            classpath: configurations.mybatisGenerator.asPath
    )
    ant.mbgenerator(overwrite: true,
            configfile: 'src/main/resources/mybatis/generatorConfig.xml', verbose: true) {
        propertyset {
            propertyref(name: 'targetProject')
            propertyref(name: 'userId')
            propertyref(name: 'driverClass')
            propertyref(name: 'connectionURL')
            propertyref(name: 'password')
            propertyref(name: 'src_main_java')
            propertyref(name: 'src_main_resources')
            propertyref(name: 'modelPackage')
            propertyref(name: 'mapperPackage')
            propertyref(name: 'sqlMapperPackage')
        }
    }
}
