把MapperFactory弄成静态变量似乎也可以解决溢出问题，我试了一下，没有报错了。代码：
package core.util;

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

/**
* Orika对象映射拷贝工具类.
*
* @Author 李程鹏
*/
public class OrikaUtils {
private static MapperFactory mapperFactory = new DefaultMapperFactory.Builder().build();
private static MapperFacade mapperFacade = mapperFactory.getMapperFacade();

/**
* <strong>Description:</strong>
* <pre>
* 映射拷贝对象.
* </pre>
*
* @param origin 原对象
* @param targetClass 目标对象的Class
* @Return {@code T} - 映射结果
*/
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);
}
}

记一次PERM区内存泄漏

现象 生产上Perm配置了400M，发生了java.lang.OutOfMemoryError: PermGen space。然调整了600M，没过过久，还是OOM了。 分析...
