本文介绍了一个关于javassist在与Dubbo集成时遇到的类找不到的问题，并详细解释了错误的原因及解决方法。主要原因是web应用的classLoader与javassist的classloader不一致导致。建议将jar包统一放置在标准目录下并注意类路径加载顺序。

场景：

javassist是动态代理用于生成字节码的一个开源组件，在web应用中与tomcat和weblogic等中间件集成的时候，遇到了这样的报错（报错在下面贴出）。

报错原因：

之所以报这个错，是因为web应用的classLoader与javassist的classloader不是同一个，那为什么不是同一个classLoader呢？一般的web应用部署到中间件时，都会把jar包放到\WEB-INF\lib的目录下，与WEB-INF\classes目录下的类文件是同一个classloader，但是我们公司在部署web应用的时候不是把jar包放到\WEB-INF\lib下，而是放到一个公共的地方。另外需要注意公共的lib目录和\WEB-INF\lib目录的classpath加载顺序，不要在两个目录都方javassist的jar包，否则也会出现同样的问题。


报错信息：

【javassist】使用javassist修改kafka源码AbstractCoordinator类这里原本有一个布尔类型的变量，根据文档【javassist】javassist 入门案例 生成类这里要用$1表示的，但是我这里怎么写都不对。如下使用if (!$1)是不对的。
javassit遇到的坑

不说一些没用的话了，直接上坑 no-such-class异常 问题：如果编译的时候遇到类似以下的异常，说明javassit是找不到这个类 javassist cannot compileexception [source error] no such class Method 解决方法 使用全限定名称，比如将Method修改为java.lang.reflect.Method getDeclaredMethod(xxx)异常 问题：编译的时候，如果遇到类似以下的异常， getDeclaredMeth.

错误：javassist.CannotCompileException: [source error] no such class 解决方案：可以尝试使用类的全限定名。原因可能是该类与你所修改的类不在一个jar包下

### JRebel CannotCompileException 错误分析 JRebel 的 `CannotCompileException` 是由于 JavaAssist 编译器无法找到指定的类或字段引起的。具体到当前场景中的 `MessageBytesCBP` 和 `hasStrValue` 字段问题，...
我弄好了,现在在弄这个,一、启动zookeeper服务和kafka服务 打开第1个终端，执行如下命令启动Zookeeper服务： cd /export/server/kafka ./bin/zookeeper-server-start.sh config/zookeeper.properties 打开第2个终端，执行如下命令启动Kafka服务： cd /export/server/kafka ./bin/kafka-server-start.sh config/server.properties 打开第3个终端，执行如下命令创建一个名为test的Topic： cd /export/server/kafka ./bin/kafka-topics.sh --create --topic test --bootstrap-server localhost:9092 二、创建配置文件nc_kafka.conf 在Flume安装目录的conf子目录下创建一个配置文件nc_kafka.conf，内容如下： # 设置Agent上的各个组件名称 a1.sources = r1 a1.sinks = k1 a1.channels = c1 # 配置Source a1.sources.r1.type = netcat a1.sources.r1.bind = localhost a1.sources.r1.port = 44444 # 配置Sink a1.sinks.k1.type = org.apache.flume.sink.kafka.KafkaSink a1.sinks.k1.kafka.topic = test a1.sinks.k1.kafka.bootstrap.servers = localhost:9092 a1.sinks.k1.kafka.flumeBatchSize = 20 a1.sinks.k1.kafka.producer.acks = 1 a1.sinks.k1.kafka.producer.linger.ms = 1 a1.sinks.k1.kafka.producer.compression.type = snappy # 配置Channel a1.channels.c1.type = memory a1.channels.c1.capacity = 1000 a1.channels.c1.transactionCapacity = 100 # 把Source和Sink绑定到Channel上 a1.sources.r1.channels = c1 a1.sinks.k1.channel = c1 三、启动flume 打开第4个终端，执行如下命令启动Flume： cd /export/server/flume ./bin/flume-ng agent --conf ./conf --conf-file ./conf/nc_kafka.conf --name a1 -Dflume.root.logger=INFO,console 四、启动监听端口 打开第5个终端，执行如下命令： nc localhost 44444 执行上面的命令以后，在该窗口内用键盘输入一些单词，如“hadoop”。这个单词会发送给Flume，然后由Flume发送给Kafka。 五、启动kafka消费者 打开第6个终端，执行如下命令启动Kafka消费者： cd /export/server/kafka ./bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic test --from-beginning 上面的命令执行以后，就可以在屏幕上看到“hadoop”，说明Kafka成功接收到了数据。 六、报错 在这里插入图片描述 Kafka 2.6.0 内置依赖的 ZooKeeper 版本是 3.4.x（无 ZKClientConfig 构造方法），但系统中 3.9.2 的 ZK 包被优先加载，或 Kafka 尝试调用 3.5+ 版本的 ZK 方法，导致版本不兼容。 进入 Kafka 安装目录的 bin 目录，编辑 kafka-server-start.sh 步骤 1：彻底隔离 Kafka 与系统独立 ZK vim /export/server/kafka/bin/kafka-server-start.sh unset CLASSPATH KAFKA_HOME=“/export/server/kafka” CLASSPATH=“$KAFKA_HOME/libs/*” 步骤2：同理修改 ZK 启动脚本 vim /export/server/kafka/bin/zookeeper-server-start.sh unset CLASSPATH KAFKA_HOME=“/export/server/kafka/” CLASSPATH=“$KAFKA_HOME/libs/*”但是我遇到问题了.打开第2个终端，执行如下命令启动Kafka服务： cd /export/server/kafka ./bin/kafka-server-start.sh config/server.properties 连接主机... 连接主机成功 Last login: Mon Dec 29 12:39:29 2025 from 192.168.81.1 [ma@master ~]$ su 密码： [root@master ma]# cd /export/server/kafka [root@master kafka]# ./bin/kafka-server-start.sh config/server.properties [2025-12-29 13:12:28,429] INFO Registered kafka:type=kafka.Log4jController MBean (kafka.utils.Log4jControllerRegistration$) [2025-12-29 13:12:29,489] INFO Setting -D jdk.tls.rejectClientInitiatedRenegotiation=true to disable client-initiated TLS renegotiation (org.apache.zookeeper.common.X509Util) [2025-12-29 13:12:29,602] INFO Registered signal handlers for TERM, INT, HUP (org.apache.kafka.common.utils.LoggingSignalHandler) [2025-12-29 13:12:29,610] INFO starting (kafka.server.KafkaServer) [2025-12-29 13:12:29,611] INFO Connecting to zookeeper on 192.168.81.130:2181,192.168.81.131:2181,192.168.81.132:2181 (kafka.server.KafkaServer) [2025-12-29 13:12:29,658] INFO [ZooKeeperClient Kafka server] Initializing a new session to 192.168.81.130:2181,192.168.81.131:2181,192.168.81.132:2181.

解决javassist在SpringBoot环境下找不到类的问题

问题 最近在玩javassit的时候（利用java代理实现对代码的运行时修改），碰到了一个问题。 目标应用是一个SpringBoot应用，我需要修改Spring MVC中的一个类InterceptorRegisty，动态增加一个拦截器。 当我直接在IDE中带agent参数运行这个应用时，没有问题，可当打包成jar后运行时，却抛出找不到类的异常： javassist.NotFoundException: org.springframework.web.servlet.config.annotation

javassist使用中遇到的问题记录

Javassit提供了运行时操作Java字节码的方法，其效率低于asm。javassist主要是提供了代码级别的修改(也有bytecode级别)，相比与asm的字节码级别的修改，学习成本低，开发效率高。因此，在实际应用中javassist是一个非常不错的选择。以下是在使用javassist的过程中碰到的问题及处理方法：         1、ClassLoader问题

添加接口后dubbo启动失败，抛出的异常。各种调试、测试，没有发现代码的问题。 于是百度了一下，说可能是由于提供的接口以getXXX 开头，而且接口没有返回值，从而出现此种异常。因此尝试修改方法名称，再次启动，成功！ 果然因为如此！ 但是这是为什么呐？ 原因在于dubbo暴露服务，将getxxx开头的方法，当做获取属性方法来进行编译，然后方法没有返回值，所以抛出异常。 贴上dubbo的动...
