代码自动生成工具
一、简介
1.1 概述

CodeGenerator是一个轻量的代码生成工具，可以在常规的项目开发初始阶段生成model、dao、Mapper、
mapper（mybatis）、service、controller，项目思路来源于mybatis－generator，不过代码更加简洁易控制

1.2 特性
  1.2.1、代码运行既可以下载源码运行AppTest测试用例，也可以使用maven插件的方式运行（推荐使用）
  1.2.2、代码模块可以自定义生成，比如只需要model、dao，Mapper、mapper的代码，可以在配置文件配置，生成目录也可以配置，规则是约定大于配置
  1.2.3、可以修改自定义的模版样式

1.3 使用方式
  1.3.1、首页check源码在本地，如果需要本地测试用例运行，请看AppTest

public class AppTest {

private static ApplicationContext context;

private static GeneratorFactoryImpl generatorFactory;

@BeforeClass
    public static void beforeClass(){
        try {
            context = new ClassPathXmlApplicationContext("classpath:spring-generator.xml");
            generatorFactory=(GeneratorFactoryImpl)context.getBean("generatorFactory");
        } catch (BeansException e) {
            e.printStackTrace();
        }
    }

@AfterClass
    public static void doAfter(){
        if(context !=null && context instanceof ClassPathXmlApplicationContext){
            ((ClassPathXmlApplicationContext) context).close();
        }
    }

@Test
    public void codeGeneratorTest() {
        generatorFactory.defaultGeneratorStarter();
    }
}

1.3.2、运行之前需要修改一下spring-generator.xml，配置每个模块的生成器

            </set>
        </property>
    </bean>
</beans>

2、运行之前需要修改一下config-generator.properties，配置数据源等信息

##mysql连接配置
jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://127.0.0.1:3306/shiro
jdbc.username=root
jdbc.password=root

generator.authorName=HuJiFang

##是否生成注释
generator.annotation=false

##生成代码位置
generator.location=src

##文件包名称
generator.project.name=main

##生成那些层
generator.layers=mapper,mapperConfig,model,service,result

##包名称
generator.basePackage=com.oneplus.code.temp

##表名称，多个用逗号分隔(,)
generator.tables=sys_privilege_menu

##过滤掉代码表的前缀
generator.table.prefix=sys_

##浮点型转化为：BigDecimal，否则转化为：Double
generator.precision=high

##生成Service domain后缀名称
generator.domain.suffix=DTO

#生成Service query domain后缀名称
generator.queryDomain.suffix=QueryDTO

1.3.3 maven插件使用方式
在pom文件中定义插件

<plugin>
    <groupId>com.oneplus.maven.plugins</groupId>
    <artifactId>code-generator</artifactId>
    <version>${codeGenerator.version}</version>
</plugin>
