JFinal框架操作oracle数据库,需要在configPlugin()方法中配置链接oracle数据库的相关配置
配置JFinal数据库操作插件,configPlugin方法
这里我加载jdbc.properties配置文件实在configConstant加载的
@Override
public void configConstant(Constants me) {
loadPropertyFile("jdbc.properties");//加载配置文件
me.setDevMode(getPropertyToBoolean("config.devModel", false));
me.setViewType(ViewType.JSP);
me.setEncoding("UTF-8");
}
jdbc.properites配置文件
oracle.driver=oracle.jdbc.driver.OracleDriver
oracle.url=jdbc:oracle:thin:@127.0.0.1:1521:orcl
oracle.username=scott
oracle.password=xiaohu
config.devModel=true
@Override
public void configPlugin(Plugins me) {
ActiveRecordPlugin arp=null;
String driver=getProperty("oracle.driver");
String url=getProperty("oracle.url");
String username=getProperty("oracle.username");
String password=getProperty("oracle.password");
DruidPlugin dp=new DruidPlugin(url, username, password, driver);
me.add(dp);
arp=new ActiveRecordPlugin(dp);//设置数据库方言
arp.setDialect(new OracleDialect());
arp.setContainerFactory(new CaseInsensitiveContainerFactory());//忽略大小写
me.add(new EhCachePlugin());
arp.addMapping("users", "id",Users.class);
me.add(arp);
}
arp.setContainerFactory(new CaseInsensitiveContainerFactory());//忽略大小写
如果不需要对数据库进行增加操作,则必须配置忽略大小写,如果不配置忽略大小写,在保存源代码的该段代码中会出现属性id找不到的异常
/**
* Save model.
*/
public boolean save() {
Config config = getConfig();
Table table = getTable();
StringBuilder sql = new StringBuilder();
List
getModifyFlag().clear();
return result >= 1;
} catch (Exception e) {
throw new ActiveRecordException(e);
} finally {
config.close(pst, conn);
}
}
getGeneratedKey()源代码部分
/**
* Get id after save method.
*/
private void getGeneratedKey(PreparedStatement pst, Table table) throws SQLException {
String pKey = table.getPrimaryKey();
if (get(pKey) == null || getConfig().dialect.isOracle()) {
ResultSet rs = pst.getGeneratedKeys();
if (rs.next()) {
Class colType = table.getColumnType(pKey);
if (colType == Integer.class || colType == int.class)
set(pKey, rs.getInt(1));
else if (colType == Long.class || colType == long.class)
set(pKey, rs.getLong(1));
else
set(pKey, rs.getObject(1)); // It returns Long object for int colType
rs.close();
}
}
}
/**
* Set attribute to model.
* @param attr the attribute name of the model
* @param value the value of the attribute
* @return this model
* @throws ActiveRecordException if the attribute is not exists of the model
*/
public M set(String attr, Object value) {
if (getTable().hasColumnLabel(attr)) {//执行到这里返回false
attrs.put(attr, value);
getModifyFlag().add(attr); // Add modify flag, update() need this flag.
return (M)this;
}
throw new ActiveRecordException("The attribute name is not exists: " + attr);//抛出该异常
}
实体类:
package com.tenghu.core.model;
import com.jfinal.plugin.activerecord.Model;
public class Users extends Model{
public static Users dao=new Users();
}
操作数据:
Users users=new Users();
users.set("id", "users_sequence.nextval");
users.set("username", "张三");
users.set("pwd", "sdfsdfs");
users.save();
List testList=Users.dao.find("select * from users");
