@JFinal 波哥,好像挺多人呼吁的,可以考虑出个官方的quartz plugin

2024-04-01 20:59

测试了一下:
使用
set CP=%APP_BASE_PATH%config;%APP_BASE_PATH%lib\*;%APP_BASE_PATH%classes
会报错:
java.lang.ClassCastException: com.xir.xverse.core.XVerseConfig cannot be cast to com.jfinal.config.JFinalConfig

改为:
set CP=%APP_BASE_PATH%config;%APP_BASE_PATH%lib\*;%APP_BASE_PATH%classbean
则可以正常运行

是因为classes比较特殊么?

问题已解决,感谢波哥

根据波哥指导,配置了log4j.properties
得到的报错:
[ERROR]-[com.jfinal.core.ActionHandler.handle()]: com.xir.hyper.trace.controller.TraceController.trace() : /trace?sn=000001211069997
java.lang.NullPointerException: Cannot invoke "com.jfinal.plugin.activerecord.Record.getStr(String)" because "record" is null

哦,我理解错了,您是想知道如何通过JFinal的Model类来生成数据库表结构对吧?其实,JFinal也提供了类似于Hibernate的“反向工程”功能,可以通过Model类生成对应的数据库表结构。具体操作如下:

1. 在项目的配置文件`config.properties`中添加以下配置项:

```
# 数据库连接信息
jdbcUrl=jdbc:mysql://localhost:3306/mydb
user=root
password=root

# model 生成器配置
model.packageName=com.example.model
model.template=/template/model_template.jf
model.baseModelPackageName=com.example.model.base
model.baseModelOutputDir=src/main/java/com/example/model/base
model.modelOutputDir=src/main/java/com/example/model
```

其中,`jdbcUrl`、`user`、`password`分别是你的数据库连接信息,`model.packageName`是生成的Model类的包名,`model.template`是生成Model类的模板文件路径,`model.baseModelPackageName`是生成的BaseModel类的包名,`model.baseModelOutputDir`是生成的BaseModel类的输出目录,`model.modelOutputDir`是生成的Model类的输出目录。

2. 创建Model类

在项目的`com.example.model`包下创建一个继承自`com.jfinal.plugin.activerecord.Model`的Java类,例如:

```java
package com.example.model;

import com.jfinal.plugin.activerecord.Model;

public class User extends Model {
public static final User dao = new User();
}
```

这里我们创建了一个名为`User`的Model类,它继承自`Model`,并且定义了一个静态的`dao`对象,用来进行数据库操作。

3. 生成数据库表结构

然后,我们可以使用JFinal提供的`Generator`类来生成数据库表结构。在项目的`/src/main/java`目录下创建一个Java类,例如:

```java
package com.example;

import com.jfinal.plugin.activerecord.generator.Generator;
import com.jfinal.plugin.druid.DruidPlugin;
import com.jfinal.kit.PathKit;
import java.util.ArrayList;
import java.util.List;

public class AppGenerator {
public static void main(String[] args) {
// 初始化数据库连接
DruidPlugin dp = new DruidPlugin("jdbc:mysql://localhost:3306/mydb", "root", "root");
dp.start();

// 配置Generator
Generator generator = new Generator(dp.getDataSource(), "com.example.model", PathKit.getWebRootPath() + "/src/main/java");

// 添加需要生成的Model类
generator.addIncludedTable("user");

// 设置生成的BaseModel类名
generator.setBaseModelName("BaseModel");

// 设置生成的Model类是否继承BaseModel
generator.setGenerateChainSetter(true);



问了chatGTP,得到了这个答案。
