javassist一个很奇怪的问题

采用javassist来将一个类中的field改变类型。待改变的类代码如下:

[code="java"]public class JassistTest {

@Autowired
private StpService stpService;

public void doit(Long userid){
    PeakSeasonMainResponse res = stpService.getPeakOverView(userid);
    System.out.println(stpService.getClass().getName());
    System.out.println("hello" + res);
}

}[/code]

进行改变操作的类如下:
[code="java"]public class TestMain {

public TestMain(){

}

public static void main(String[] args) throws Exception{


    ClassPool pool = ClassPool.getDefault();
    CtClass cc = pool.get("JassistTest");
    CtField f = cc.getDeclaredField("stpService");
    cc.removeField(f);
    cc.addField(CtField.make("private Proxy stpService;", cc));
    cc.writeFile("D:\\DevProgram\\eclipse-jee-kepler-R-win32\\workspace\\stable\\fc-deimos\\target\\test-classes");

    JassistTest test = new JassistTest();
    test.doit(7060L);



}

}
[/code]

class文件生成后,我用反编译工具查看,Javassist已经变为如下:

[code="java"]public class JassistTest
{
private Proxy stpService;

public void doit(Long userid)
{
PeakSeasonMainResponse res = this.stpService.getPeakOverView(userid);
System.out.println(this.stpService.getClass().getName());
System.out.println("hello" + res);
}
}[/code]

但当我执行TestMain.java文件中的test.doit()方法时,还是报异常了。
[code="java"]Exception in thread "main" java.lang.NoSuchFieldError: stpService
at JassistTest.doit(JassistTest.java:13)
at TestMain.main(TestMain.java:33)
[/code]

实在搞不懂,请教大家

感觉跟classloader有关,
试试这样,分开两次执行。第一次生成新的class,第二次把在path里直接使用新的class文件

iteye_2355
iteye_2355 我自己2了。class文件在生成时候已经记录field和method的相关信息了。如果改了field的类型,那么对应函数确实已经不能用了。

suziwen 这个我现在也不太确定,现在对classloader的具体顺序也是忘记差不多了。只是感觉你new的话,可能这个class定义 已经加载到内存里了,所以还是旧的class

iteye_2355
iteye_2355 我用javassist在writefile的时候,是覆盖回classpath下的class文件,然后new的时候,classloader才去读取的吧?那时候已经重写完class文件了应该。

关于javassist的一些API参数的疑问
``` ClassPool pool = ClassPool.getDefault(); CtClass cc = pool.get("test.Emp"); CtMethod m = new CtMethod(CtClass.intType, "add", new CtClass[]{CtClass.intType}, cc); m.setModifiers(Modifier.PUBLIC); m.setBody("{return n;}"); cc.addMethod(m); ``` 这个包下有很多这样的API,CtMethod里的前面的参数我都明白是对方法的描述,但最后一个参数我不清楚有什么用,它并没有把方法写进cc里,又对方法的定义没作用。

关于javassist重复加载的问题
最近需要使用javassist动态改变类里的方法,问题是javassist使用过一次以后,第二次使用就会冻结,可是在第二次就算用了解冻,调用toclass以后还是会报异常,主要是为了得到frmAttributesI的实体,怎样已经冻结的class解冻之后还可以继续编辑修改并调用呢? String body = null; CtClass cc = null; IFrmAttributes frmAttributesI = null; //从数据查找判断是否是二次加载 String isCondUpdate = "Y"; if(isClassInit == false){ //第一次调用 // 获取所有条件信息(执行脚本) ClassPool pool = ClassPool.getDefault(); //导入相关jar包 pool.importPackage("java.util.Hashtable"); pool.importPackage("java.util.List"); pool.importPackage("java.util.Date"); pool.importPackage("java.text.SimpleDateFormat"); // 在外部变量执行类中,动态加载外部变量执行算法 cc = pool.get("com.process.FrmAttributes"); CtMethod cm = cc.getDeclaredMethod("process"); //cc.defrost(); System.out.println("测试1=================="+body.toString()); cm.setBody("{" + body.toString() + "}"); Class c = cc.toClass(); frmAttributesI = (FrmAttributes) c.newInstance(); this.isClassInit = true; }else{ if(isCondUpdate == "Y"){ frmAttributesI = null; ClassPool pool2 = ClassPool.getDefault(); cc = pool2.get("com.process.FrmAttributes"); if(cc.isFrozen()){ cc.defrost(); } //删除方法,增加方法,试试二次加载 //第二次调用 CtMethod cm2 = cc.getDeclaredMethod("process"); System.out.println("测试2============================"+body.toString()); cm2.setBody("{" + body.toString() + "}"); cc.writeFile(); Class c = cc.toClass(); frmAttributesI = (FrmAttributes) c.newInstance(); } }
javassist hibernate 应用问题
需求: 1、当服务启动时,根据hbm.xml动态创建相应的pojo,并不是生成.java或.class,是用javassist动态创建的。(已经完成) 2、根据前台请求,先修改对应的hbm.xml,用的是dom4j,然后动态去修改前面动态生成的pojo,这个也是用javassist改的,但是在修改的最后,toClass()的时候抛出异常,说是存在同一个类。这时候我就没有继续toClass(),然后用ClassPool获得了修改后的pojo,检测了一下修改的情况,确实是修改好了,添加上了该添加的字段。这时候,相应的hbm.xml和pojo都已经修改好了,按说如果我重新rebuildsession后,再用hql查询这个pojo的话,对应动态添加的这个字段应该是null。 这时候问题出现了: 我查询出的pojo仍然是以前未修改的那个,新生成的字段并没有出现。并且我在hibernate.cfg.xml里面配置了<property name="hbm2ddl.auto">update</property>,按道理数据库的表中也应该自动生成相应的字段,这时候也没有生成。 我分析是我动态修改的类没有和session再次绑定,所以session里面还是以前的那个类;第二,数据库表没有生成相应的字段,就是因为configuration.configure(filename)好像带了缓存,它根本就不读修改后的hbm.xml(这个我做了个实验,在运行时我把hbm.xml删了,可是没反应)。 我想不出办法解决,请诸位帮忙,谢谢!

搭建SSM项目, pom文件的 Spring的依赖疑问, 可以这样设置 Spring的依赖么?
**1. 问题描述:** 在尝试这搭建 SSM 项目的过程中, 我是看着 Spring的结构图去添加 pom.xml 中的依赖的, 比如 core部分只需要添加 spring-context 依赖即可. 然后 context 会自动去依赖 core, beans, aop, expression. 所以, 在搭建SSM项目时, Spring 依赖我只添加六个了 context, orm, webmvc, context-support, aspects, test 如果不需要日志和测试的话, 后面两个去掉 也是可以的. 请问各位大佬, 这样子搭建, 符不符合规范??? ** 2. 相关代码:** ``` <?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0"

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。
程序员必须掌握的核心算法有哪些?
由于我之前一直强调数据结构以及算法学习的重要性,所以就有一些读者经常问我,数据结构与算法应该要学习到哪个程度呢?,说实话,这个问题我不知道要怎么回答你,主要取决于你想学习到哪些程度,不过针对这个问题,我稍微总结一下我学过的算法知识点,以及我觉得值得学习的算法。这些算法与数据结构的学习大多数是零散的,并没有一本把他们全部覆盖的书籍。下面是我觉得值得学习的一些算法以及数据结构,当然,我也会整理一些看过

死磕YOLO系列,YOLOv1 的大脑、躯干和手脚
YOLO 是我非常喜欢的目标检测算法,堪称工业级的目标检测,能够达到实时的要求,它帮我解决了许多实际问题。 这就是 YOLO 的目标检测效果。它定位了图像中物体的位置,当然,也能预测物体的类别。 之前我有写博文介绍过它,但是每次重新读它的论文,我都有新的收获,为此我准备写一个系列的文章来详尽分析它。这是第一篇,从它的起始 YOLOv1 讲起。 YOLOv1 的论文地址:https://www.c

记一次腾讯面试:进程之间究竟有哪些通信方式?如何通信? ---- 告别死记硬背
有一次面试的时候,被问到进程之间有哪些通信方式,不过由于之前没深入思考且整理过,说的并不好。想必大家也都知道进程有哪些通信方式,可是我猜很多人都是靠着”背“来记忆的,所以今天的这篇文章,讲给大家详细着讲解他们是如何通信的,让大家尽量能够理解他们之间的区别、优缺点等,这样的话,以后面试官让你举例子,你也能够顺手拈来。 1、管道 我们来看一条 Linux 的语句 netstat -tulnp | gr...
20行Python代码爬取王者荣耀全英雄皮肤
引言 王者荣耀大家都玩过吧,没玩过的也应该听说过,作为时下最火的手机MOBA游戏,咳咳,好像跑题了。我们今天的重点是爬取王者荣耀所有英雄的所有皮肤,而且仅仅使用20行Python代码即可完成。 准备工作 爬取皮肤本身并不难,难点在于分析,我们首先得得到皮肤图片的url地址,话不多说,我们马上来到王者荣耀的官网: 我们点击英雄资料,然后随意地选择一位英雄,接着F12打开调试台,找到英雄原皮肤的图片
网络(8)-HTTP、Socket、TCP、UDP的区别和联系
TCP/IP协议是传输层协议,主要解决数据如何在网络中传输,而HTTP是应用层协议,主要解决如何包装数据。 一、TCP与UDP的不同 1. 是否需要建立连接。 UDP在传送数据之前不需要先建立连接;TCP则提供面向连接的服务; 2. 是否需要给出确认 对方的传输层在收到UDP报文后,不需要给出任何确认,而 TCP需要给出确认报文,要提供可靠的、面向连接的传输服务。 3.虽然UDP不提供可靠交...

防劝退!数据结构和算法难理解?可视化动画带你轻松透彻理解!
大家好,我是 Rocky0429,一个连数据结构和算法都不会的蒟蒻… 学过数据结构和算法的都知道这玩意儿不好学,没学过的经常听到这样的说法还没学就觉得难,其实难吗?真难! 难在哪呢?当年我还是个小蒟蒻,初学数据结构和算法的时候,在忍着枯燥看完定义原理,之后想实现的时候,觉得它们的过程真的是七拐八绕,及其难受。 在简单的链表、栈和队列这些我还能靠着在草稿上写写画画理解过程,但是到了数论、图...

昨日,2019年两院院士正式官宣,一时间抢占了各大媒体头条。 朋友圈也是一片沸腾,奔走相告,赶脚比自己中了大奖还嗨皮! 谁叫咱家导师就是这么厉害呢!!! 而就在最近,新一年度的IEEE/ACM Fellow也将正式公布。 作为学术届的顶级荣誉,不自然地就会将院士与Fellow作比较,到底哪个含金量更高呢? 学术君认为,同样是专业机构对学者的认可,考量标准不一,自然不能一概而论。 但...
聊聊C语言和指针的本质
坐着绿皮车上海到杭州,24块钱,很宽敞,在火车上非正式地聊几句。 很多编程语言都以 “没有指针” 作为自己的优势来宣传,然而,对于C语言,指针却是与生俱来的。 那么,什么是指针,为什么大家都想避开指针。 很简单, 指针就是地址,当一个地址作为一个变量存在时,它就被叫做指针,该变量的类型,自然就是指针类型。 指针的作用就是,给出一个指针,取出该指针指向地址处的值。为了理解本质,我们从计算机模型说起...

究竟你适不适合买Mac?
我清晰的记得,刚买的macbook pro回到家,开机后第一件事情,就是上了淘宝网,花了500元钱,找了一个上门维修电脑的师傅,上门给我装了一个windows系统。。。。。。 表砍我。。。 当时买mac的初衷,只是想要个固态硬盘的笔记本,用来运行一些复杂的扑克软件。而看了当时所有的SSD笔记本后,最终决定,还是买个好(xiong)看(da)的。 已经有好几个朋友问我mba怎么样了,所以今天尽量客观

程序员一般通过什么途径接私活?
二哥,你好,我想知道一般程序猿都如何接私活,我也想接,能告诉我一些方法吗? 上面是一个读者“烦不烦”问我的一个问题。其实不止是“烦不烦”,还有很多读者问过我类似这样的问题。 我接的私活不算多,挣到的钱也没有多少,加起来不到 20W。说实话,这个数目说出来我是有点心虚的,毕竟太少了,大家轻喷。但我想,恰好配得上“一般程序员”这个称号啊。毕竟苍蝇再小也是肉,我也算是有经验的人了。 唾弃接私活、做外

关于研发效能提升的思考
研发效能提升是最近比较热门的一个话题,本人根据这几年的工作心得,做了一些思考总结,由于个人深度有限,暂且抛转引入。 三要素 任何生产力的提升都离不开这三个因素:人、流程和工具,少了其中任何一个因素都无法实现。 人,即思想,也就是古人说的“道”,道不同不相为谋,是制高点,也是高层建筑的基石。 流程,即方法,也是古人说的“法”。研发效能的提升,也就是要提高投入产出比,既要增加产出,也要减...

大家好,我是 Rocky0429,一个最近老在 GitHub 上闲逛的蒟蒻… 特别惭愧的是,虽然我很早就知道 GitHub,但是学会逛 GitHub 的时间特别晚。当时一方面是因为菜,看着这种全是英文的东西难受,不知道该怎么去玩,另一方面是一直在搞 ACM,没有做一些工程类的项目,所以想当然的以为和 GitHub 也没什么关系(当然这种想法是错误的)。 后来自己花了一个星期看完了 Pyt...
