把MapperFactory弄成靜態(tài)變量似乎也可以解決溢出問(wèn)題，我試了一下，沒(méi)有報(bào)錯(cuò)了。代碼：
package core.util;

import ma.glasnost.orika.MapperFacade;
import ma.glasnost.orika.MapperFactory;
import ma.glasnost.orika.impl.DefaultMapperFactory;

/**
* Orika對(duì)象映射拷貝工具類(lèi).
*
* @Author 李程鵬
*/
public class OrikaUtils {
private static MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
private static MapperFacade mapperFacade = mapperFactory.getMapperFacade();

/**
* <strong>Description:</strong>
* <pre>
* 映射拷貝對(duì)象.
* </pre>
*
* @param origin 原對(duì)象
* @param targetClass 目標(biāo)對(duì)象的Class
* @Return {@code T} - 映射結(jié)果
*/
public static <T> T map(Object origin, Class<T> targetClass) {
// MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
// MapperFacade mapperFacade = mapperFactory.getMapperFacade();
return mapperFacade.map(origin, targetClass);
}
}

記一次PERM區(qū)內(nèi)存泄漏

現(xiàn)象 生產(chǎn)上Perm配置了400M，發(fā)生了java.lang.OutOfMemoryError: PermGen space。然調(diào)整了600M，沒(méi)過(guò)過(guò)久，還是OOM了。 分析...
