HDC调试需求开发（15万预算）,能者速来！>>>


@JFinal 你好，想跟你请教个问题：
我使用的是官网上的demo，然后在configPlugin中添加了AutoTableBindPlugin相关的内容。
完整的 configPlugin代码如下:
/**
* 配置插件
*/
public void configPlugin(Plugins me) {
// 配置C3p0数据库连接池插件
C3p0Plugin c3p0Plugin = new C3p0Plugin(getProperty("jdbcUrl"), getProperty("user"), getProperty("password").trim());
me.add(c3p0Plugin);

AutoTableBindPlugin atbp = new AutoTableBindPlugin(c3p0Plugin,SimpleNameStyles.UP_UNDERLINE);
atbp.setShowSql(true);
atbp.setDialect(new MysqlDialect());
me.add(atbp);

// 配置ActiveRecord插件
ActiveRecordPlugin arp = new ActiveRecordPlugin(c3p0Plugin);
me.add(arp);
arp.addMapping("blog", Blog.class); // 映射blog 表到 Blog模型

}
jdk为1.8.0_20，tomcat为8.0.9，数据库为mysql。相关jar包如下:

在使用tomcat启动项目时遇到了如下错误:
