rapid-generator自動生成代碼步驟
最近找了個開源的代碼生成器rapid-generator，感覺挺好使的，所以這裡就分享下操作步驟。
1使用eclipse或idea創建一個maven工程
2配置依賴pom.xml

3在源碼路徑下新建generator.xml文件，並做如下配置
<?xml version="1.0" encoding="GBK"?>
<!DOCTYPE properties SYSTEM "http://java.sun.com/dtd/properties.dtd">
<properties>
<comment>
代碼生成器配置文件:
1.會為所有的property生成property_dir屬性,如pkg=com.company => pkg_dir=com/company
2.可以引用環境變數: ${env.JAVA_HOME} or System.properties: ${user.home},property之間也可以相互引用

4在源碼路徑下新建template目錄，並將rapid-generator-template-4.0.6generator emplate
apidshareasic路徑下的公共文件拷貝到該目錄下
5在template編寫待生成文件的模版文件${className}.java.ftl
<#include "/java_copyright.include">
<#assign className = table.className>
<#assign classNameLower = className?uncap_first>
package ${basepackage}.${table.classNameFirstLower};
<#include "/java_imports.include">
import com.linkage.agri.pojo.base.BaseEntity;
public class ${className} extends BaseEntity {
private static final long serialVersionUID = 5454155825314635342L;
<#list table.columns as column>
/**
* ${column.remarks}
*/
private ${column.simpleJavaType} ${column.columnNameLower};
</#list>
<@generateJavaColumns/>
<#macro generateJavaColumns>
<#list table.columns as column>
<#if column.isDateTimeColumn>
public String get${column.columnName}String() {
return DateConvertUtils.format(get${column.columnName}(), FORMAT_${column.constantName});
}
public void set${column.columnName}String(String ${column.columnNameLower}) {
set${column.columnName}(DateConvertUtils.parse(${column.columnNameLower}, FORMAT_${column.constantName},${column.simpleJavaType}.class));
}
</#if>
public void set${column.columnName}(${column.simpleJavaType} ${column.columnNameLower}) {
this.${column.columnNameLower} = ${column.columnNameLower};
}
public ${column.simpleJavaType} get${column.columnName}() {
return this.${column.columnNameLower};
}

6在main方法中敲幾行代碼執行生成文件
package com.myGenerator;
import cn.org.rapid_framework.generator.GeneratorFacade;
/**
* Hello world!
*
*/
public class App {
public static void main(String[] args) {
// 模板地址
try {
String templatePath = "C:\Users\yuxl\myproject\myGenerator\src\main\java\template";
GeneratorFacade g = new GeneratorFacade();
g.getGenerator().addTemplateRootDir(templatePath);
// 刪除生成器的輸出目錄//
// g.deleteOutRootDir();
// 通過資料庫表生成文件
g.generateByTable("user_info");
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

Fri Nov 02 13:54:10 CST 2018 WARN: Establishing SSL connection without server"s identity verification is not recommended. According to MySQL 5.5.45+, 5.6.26+ and 5.7.6+ requirements SSL connection must be established by default if explicit option isn"t set. For compliance with existing applications not using SSL the verifyServerCertificate property is set to "false". You need either to explicitly disable SSL by setting useSSL=false, or set useSSL=true and provide truststore for server certificate verification.
