maven mybatis-generator

spring-mybatis很好用，尤其是配上mybatis-generator之后，感觉倍爽。最开始使用的时候，虽然生成了代码文件，但是一大堆注释也是醉了。后来研究之，不用修改源码也可以去掉那些我不太喜欢的注释，并且添加了序列化和tostring方法，使用配置如下：

1、配置pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.example</groupId>
    <artifactId>mybatis-generator</artifactId>
    <version>0.0.1-alpha</version>
    <packaging>jar</packaging>

    <properties>
        <java.version>1.8</java.version>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.apache.commons</groupId>
            <artifactId>commons-lang3</artifactId>
            <version>3.4</version>
        </dependency>

        <dependency>
            <groupId>commons-codec</groupId>
            <artifactId>commons-codec</artifactId>
            <version>1.9</version>
        </dependency>

        <dependency>
            <groupId>org.slf4j</groupId>
            <artifactId>jcl-over-slf4j</artifactId>
            <version>1.7.12</version>
        </dependency>

        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.12</version>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-compiler-plugin</artifactId>
                <version>3.3</version>
                <configuration>
                    <source>${java.version}</source>
                    <target>${java.version}</target>
                </configuration>
            </plugin>

            <!-- mybatis 代码生成器插件 -->
            <plugin>
                <groupId>org.mybatis.generator</groupId>
                <artifactId>mybatis-generator-maven-plugin</artifactId>
                <version>1.3.2</version>
                <configuration>
                    <configurationFile>${basedir}/src/main/resources/config/generatorConfig.xml</configurationFile>
                    <verbose>true</verbose>
                    <overwrite>true</overwrite>
                </configuration>
                <dependencies>
                    <dependency>
                        <groupId>mysql</groupId>
                        <artifactId>mysql-connector-java</artifactId>
                        <version>5.1.34</version>
                    </dependency>
                </dependencies>
            </plugin>

        </plugins>
    </build>
</project>

2、配置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">

<!-- 使用 mvn mybatis-generator:generate -->
<generatorConfiguration>
    <!-- 配置文件 -->
    <properties resource="config/datasource.properties"/>
    <context id="gcldTables" targetRuntime="MyBatis3" defaultModelType="flat">

        <!-- plugin -->
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"/>
        <plugin type="org.mybatis.generator.plugins.ToStringPlugin"/>

        <!-- 取消生成的代码注释 -->
        <commentGenerator>
            <property name="suppressAllComments" value="true"/>
        </commentGenerator>

        <!-- 连接配置 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
                        connectionURL="${datasource.druid.url}" userId="${datasource.druid.username}"
                        password="${datasource.druid.password}">
        </jdbcConnection>

        <!-- javaModelGenerator是模型的生成信息，这里将指定这些Java model类的生成路径 -->
        <javaModelGenerator targetPackage="generator.model"
                            targetProject="src/main/java">
            <property name="trimStrings" value="true"/>
        </javaModelGenerator>

        <!-- 生成Mapper 配置文件 -->
        <sqlMapGenerator targetPackage="sqlMapperXml"
                         targetProject="src/main/resources">
        </sqlMapGenerator>

        <!-- javaClientGenerator是应用接口的生成信息 -->
        <javaClientGenerator type="XMLMAPPER"
                             targetPackage="generator.mapper" targetProject="src/main/java">
            <property name="enableSubPackages" value="true"/>
        </javaClientGenerator>

        <!-- oracle 使用 schema 对应 用户名称空间 mysql 使用 catalog 对应 数据库 -->
        <table schema="generate" tableName="%" enableCountByExample="false"
               enableDeleteByExample="false" enableUpdateByExample="false"
               selectByExampleQueryId="false" enableSelectByExample="false">
            <generatedKey column="id" sqlStatement="MySql" identity="true"/>
        </table>

    </context>
</generatorConfiguration>

3、数据库配置 datasource.properties

##Druid config --Database 数据库配置信息
datasource.druid.url:jdbc:mysql://localhost:3306/generator?characterEncoding=utf8
datasource.druid.driverClassName:com.mysql.jdbc.Driver
datasource.druid.username:root
datasource.druid.password:123456

datasource.druid.filters:stat,wall
datasource.druid.initialSize:2
datasource.druid.maxActive:200
datasource.druid.minIdle:2
datasource.druid.testOnBorrow:true
datasource.druid.testOnReturn:false
datasource.druid.testWhileIdle:true
datasource.druid.poolPreparedStatements:false

4、配置完成 Terminal执行命令：

mvn mybatis-generator:generate
