第一次创建Jfinal框架

这里是记录一下我的电脑上eclipse创建Jfinal项目时要注意的一些问题。

1、首先创建Maven项目

我们需要的是web项目，所以选择webapp这一项

2、创建pom.xml文件，下载相关jar包

在整个项目上右键点击，选择.xml文件。这是我用的pom.xml文件的代码，来自于以前第一次做的项目里面，基本能满足需要。

		        </connectors>

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

3、修改web.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

    <filter>
    	<filter-name>jfinal</filter-name>
    	<filter-class>com.jfinal.core.JFinalFilter</filter-class>
    	<init-param>
   			 <param-name>configClass</param-name>
   			 //记得修改这里
   			 <param-value>com.项目名称.config.config</param-value>
   		 </init-param>
	</filter>


	<filter-mapping>
		<filter-name>jfinal</filter-name>
		<url-pattern>/*</url-pattern>
    </filter-mapping>

</web-app>

4、创建lo4j.properties文件

代码如下：

log4j.rootLogger=INFO, stdout, file
log4j.appender.stdout.Target=System.out
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n

# Output to the File
log4j.appender.file=org.apache.log4j.FileAppender
log4j.appender.file.File=./myapp.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%n%-d{yyyy-MM-dd HH:mm:ss}%n[%p]-[Thread: %t]-[%C.%M()]: %m%n

# Druid
log4j.logger.druid.sql=warn,stdout
log4j.logger.druid.sql.DataSource=warn,stdout
log4j.logger.druid.sql.Connection=warn,stdout
log4j.logger.druid.sql.Statement=debug,stdout
log4j.logger.druid.sql.ResultSet=warn,stdout

5、建包之前的错误处理

刚创建好的maven项目结构是这样的：

打开Build Path发现有错误，此时我们把这两个missing的文件夹Remove掉（resource文件夹也可以remove掉），然后Add Folder添加上第一个文件夹/src/mian/java：



之后就可以得到我们想要的结构，创建两个包：tool包和config包

6、config包和tool包

(1)、config.java代码（基本配置文件）

package com.JfinalTest.config;

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.json.JacksonFactory;
import com.jfinal.kit.PathKit;
import com.jfinal.kit.PropKit;
import com.jfinal.log.Log4jLogFactory;
import com.jfinal.plugin.activerecord.ActiveRecordPlugin;
import com.jfinal.plugin.druid.DruidPlugin;
import com.jfinal.template.Engine;



public class config extends JFinalConfig{
	
	//基础设置
	public void configConstant(Constants me)
	{
		//PropKit 读取工具
	    PropKit.use("com/JfinalTest/config/jdbc.properties");
	    me.setDevMode(PropKit.getBoolean("devMode"));
	    me.setEncoding("UTF-8");
	    me.setJsonFactory(new JacksonFactory());
	    me.setJsonDatePattern("yyyy-MM-dd");
	    
	    me.setLogFactory(new Log4jLogFactory());
	}
	
	
	
	

	//路由分包
    public void configRoute(Routes me) {

    }
    
    //排至前端模板引擎
    public void configEngine(Engine me) { 	
    	
    }

    
	public static DruidPlugin createDruidPlugin() {
		return new DruidPlugin(PropKit.get("jdbc_url"), PropKit.get("jdbc_username"), PropKit.get("jdbc_password").trim());
	}
    

    public void configPlugin(Plugins me) {  	

/*    	DruidPlugin druidPlugin = new DruidPlugin(PropKit.get("jdbc_url"), PropKit.get("jdbc_username"), PropKit.get("jdbc_password").trim());
        me.add(druidPlugin);
    			
        ActiveRecordPlugin arp = new ActiveRecordPlugin(druidPlugin);
        
        arp.setBaseSqlTemplatePath(PathKit.getRootClassPath());
    	arp.addSqlTemplate("Tool.sql");
    	arp.setShowSql(true);
        
     
       _MappingKit.mapping(arp);
        me.add(arp);
       */
       
    }
    

    //拦截器，配置文件里的为全局拦截器
    public void configInterceptor(Interceptors interceptors) {
    
    }
    

   
    public void configHandler(Handlers me) {
    
    	//me.add(new ResourceHandler());
    }
    
    
    public void afterJFinalStart() {
    }
     
 
    public void beforeJFinalStop() {
    }
    
}

(2)、jdbc.properties文件

jdbc_driverClassName=com.mysql.jdbc.Driver
jdbc_url=jdbc:mysql://localhost:3306/数据库名称?characterEncoding=utf8&zeroDateTimeBehavior=convertToNull
jdbc_username=root
jdbc_password=
devMode=true

(3)、_JFinalDemoGenerator.java文件（创建Model层）

package com.JfinalTest.tool;

import javax.sql.DataSource;

import com.JfinalTest.config.config;
import com.jfinal.kit.PathKit;
import com.jfinal.kit.PropKit;
import com.jfinal.plugin.activerecord.generator.Generator;
import com.jfinal.plugin.druid.DruidPlugin;

public class _JFinalDemoGenerator {
	
	public static DataSource getDataSource() {
		PropKit.use("com/JfinalTest/config/jdbc.properties");
		DruidPlugin druidPlugin = config.createDruidPlugin();
		druidPlugin.start();
		return druidPlugin.getDataSource();
	}
	
	public static void main(String[] args) {
		// base model 所使用的包名
		String baseModelPackageName = "com.JfinalTest.Model.base";
		// base model 文件保存路径
		String baseModelOutputDir = PathKit.getWebRootPath() + "/src/main/java/com/JfinalTest/Model/base";
		
		// model 所使用的包名 (MappingKit 默认使用的包名)
		String modelPackageName = "com.JfinalTest.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();
		// 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();
	}
}

(4)、start.java文件（启动Jfinal项目）

package com.JfinalTest.tool;

import com.jfinal.core.JFinal;

public class start {

	public static void main(String[] args) {
		//eclipse
		JFinal.start("src/main/webapp",8080,"/",5);
		
/*		//IDEA
		JFinal.start("src/main/webapp",80,"/");*/
	}
}

7、启动项目

这样表示启动成功：
