xialinlin的动态消息

应用于 SQL 管理的 Engine 对象的配置在 configPlugin(Plugins me) 中进行：

public void configPlugin(Plugins me) {
ActiveRecordPlugin arp = new ActiveRecordPlugin(...);
Engine engine = arp.getEngine();

// 上面的代码获取到了用于 sql 管理功能的 Engine 对象，接着就可以开始配置了
engine.setToClassPathSourceFactory();
engine.addSharedMethod(new StrKit());

me.add(arp);
}

如果是：Jackson的话配置一下即可

import java.io.IOException;

import com.fasterxml.jackson.core.JsonGenerator;
import com.fasterxml.jackson.databind.JsonSerializer;
import com.fasterxml.jackson.databind.SerializerProvider;
import com.jfinal.plugin.activerecord.Record;

public class RecordJackSonSerializer extends JsonSerializer {

@Override
public void serialize(Record record, JsonGenerator gen, SerializerProvider serializers) throws IOException {
gen.writeObject(record.getColumns());
}
}
