运行_JFinalDemoGenerator生成实体类和映射之前的项目结构：
运行之后：
生成和改变的文件：
实体类：
package com.wazn.model;
import com.wazn.model.base.BaseStudent;
/**
* Generated by JFinal.
*/
@SuppressWarnings("serial")
public class Student extends BaseStudent<Student> {
public static final Student dao = new Student().dao();
}package com.wazn.model.base;
import com.jfinal.plugin.activerecord.Model;
import com.jfinal.plugin.activerecord.IBean;
/**
* Generated by JFinal, do not modify this file.
*/
@SuppressWarnings({"serial", "unchecked"})
public abstract class BaseStudent<M extends BaseStudent<M>> extends Model<M> implements IBean {
public M setStudentid(java.lang.Integer studentid) {
set("studentid", studentid);
return (M)this;
}
public java.lang.Integer getStudentid() {
return getInt("studentid");
}
public M setStudentname(java.lang.String studentname) {
set("studentname", studentname);
return (M)this;
}
public java.lang.String getStudentname() {
return getStr("studentname");
}
}package com.wazn.model;
import com.wazn.model.base.BaseBlog;
/**
* Generated by JFinal.
*/
@SuppressWarnings("serial")
public class Blog extends BaseBlog<Blog> {
public static final Blog dao = new Blog().dao();
}package com.wazn.model.base;
import com.jfinal.plugin.activerecord.Model;
import com.jfinal.plugin.activerecord.IBean;
/**
* Generated by JFinal, do not modify this file.
*/
@SuppressWarnings({"serial", "unchecked"})
public abstract class BaseBlog<M extends BaseBlog<M>> extends Model<M> implements IBean {
public M setId(java.lang.Integer id) {
set("id", id);
return (M)this;
}
public java.lang.Integer getId() {
return getInt("id");
}
public M setTitle(java.lang.String title) {
set("title", title);
return (M)this;
}
public java.lang.String getTitle() {
return getStr("title");
}
public M setContent(java.lang.String content) {
set("content", content);
return (M)this;
}
public java.lang.String getContent() {
return getStr("content");
}
public M setDate(java.lang.String date) {
set("date", date);
return (M)this;
}
public java.lang.String getDate() {
return getStr("date");
}
}自动写入映射：
package com.wazn.model;
import com.jfinal.plugin.activerecord.ActiveRecordPlugin;
/**
* Generated by JFinal, do not modify this file.
* <pre>
* Example:
* public void configPlugin(Plugins me) {
* ActiveRecordPlugin arp = new ActiveRecordPlugin(...);
* _MappingKit.mapping(arp);
* me.add(arp);
* }
* </pre>
*/
public class _MappingKit {
public static void mapping(ActiveRecordPlugin arp) {
arp.addMapping("blog", "id", Blog.class);
arp.addMapping("student", "studentid", Student.class);
}
}这里需要注意的是，JFinal中的这个自动映射文件_MappingKit因为在继承JFinalConfig类的主文件中需要指定，所以生成后会在该文件中写入，但是，如在 _JFinalDemoGenerator
中指定的 _MappingKit路径和原来的_MappingKit文件路径不一致，将会在新的指定的路径生成一个新的_MappingKit文件。
接下来是主文件：
package com.wazn.common;
import com.jfinal.config.Constants;
import com.jfinal.config.Handlers;
import com.jfinal.config.Interceptors;
import com.jfinal.config.JFinalConfig;
import com.jfinal.config.Plugins;
import com.jfinal.config.Routes;
import com.jfinal.core.JFinal;
import com.jfinal.kit.PropKit;
import com.jfinal.plugin.activerecord.ActiveRecordPlugin;
import com.jfinal.plugin.druid.DruidPlugin;
import com.jfinal.template.Engine;
import com.wazn.model._MappingKit;
public class GeneratorConfig extends JFinalConfig{
public static void main(String[] args) {
JFinal.start("src/main/webapp", 80, "/", 5);
}
@Override
public void configConstant(Constants me) {
// 加载少量必要配置，随后可用PropKit.get(...)获取值
PropKit.use("a_little_config.txt");
me.setDevMode(PropKit.getBoolean("devMode", false));
}
@Override
public void configEngine(Engine me) {
}
@Override
public void configHandler(Handlers arg0) {
// TODO Auto-generated method stub
}
@Override
public void configInterceptor(Interceptors arg0) {
// TODO Auto-generated method stub
}
@Override
public void configPlugin(Plugins me) {
// 配置 druid 数据库连接池插件
DruidPlugin druidPlugin = new DruidPlugin(PropKit.get("jdbcUrl"), PropKit.get("user"), PropKit.get("password").trim());
me.add(druidPlugin);
// 配置ActiveRecord插件
ActiveRecordPlugin arp = new ActiveRecordPlugin(druidPlugin);
// 所有映射在 MappingKit 中自动化搞定
_MappingKit.mapping(arp);
me.add(arp);
}
@Override
public void configRoute(Routes arg0) {
// TODO Auto-generated method stub
}
public static DruidPlugin createDruidPlugin() {
return new DruidPlugin(PropKit.get("jdbcUrl"), PropKit.get("user"), PropKit.get("password").trim());
}
}这里因为只是测试使用_JFinalDemoGenerator生成实体类，所以只有相关的代码，没有其他的代码配置。
_JFinalDemoGenerator生成器：
package com.wazn.model;
import javax.sql.DataSource;
import com.jfinal.kit.PathKit;
import com.jfinal.kit.PropKit;
import com.jfinal.plugin.activerecord.generator.Generator;
import com.jfinal.plugin.druid.DruidPlugin;
import com.wazn.common.GeneratorConfig;
public class _JFinalDemoGenerator {
public static DataSource getDataSource() {
PropKit.use("a_little_config.txt");
DruidPlugin druidPlugin = GeneratorConfig.createDruidPlugin();
druidPlugin.start();
return druidPlugin.getDataSource();
}
public static void main(String[] args) {
// base model 所使用的包名
String baseModelPackageName = "com.wazn.model.base";
// base model 文件保存路径
String baseModelOutputDir = PathKit.getWebRootPath() + "/src/main/java/com/wazn/model/base";
// model 所使用的包名 (MappingKit 默认使用的包名)
String modelPackageName = "com.wazn.model";
// model 文件保存路径 (MappingKit 与 DataDictionary 文件默认保存路径)
String modelOutputDir = baseModelOutputDir + "/..";
// 创建生成器
Generator generator = new Generator(getDataSource(), baseModelPackageName, baseModelOutputDir, modelPackageName, modelOutputDir);
// 设置是否生成链式 setter 方法
generator.setGenerateChainSetter(false);
// 添加不需要生成的表名
generator.addExcludedTable("adv");
// 设置是否在 Model 中生成 dao 对象
generator.setGenerateDaoInModel(true);
// 设置是否生成链式 setter 方法
generator.setGenerateChainSetter(true);
// 设置是否生成字典文件
generator.setGenerateDataDictionary(false);
// 设置需要被移除的表名前缀用于生成modelName。例如表名 "osc_user"，移除前缀 "osc_"后生成的model名为 "User"而非 OscUser
generator.setRemovedTableNamePrefixes("t_");
// 生成
generator.generate();
}
