tomcat远程debug,idea远程断点

项目联机后，如果日志打印不明确或业务逻辑复杂，则可能无法确定特定的错误原因，因此可以在IDEA远程代理上进行调试。

在线的代码必须与本地的匹配！ 扎实的毛衣/p

输入：mvn clean package，（大概需要等几分钟），最好在构建之前指定本地repository，就不需要重新下载jar包了。

3、在IDEA配置远程Debug 指定socket port = 8081，指定准备debug的模块 4、在终端启动刚才打好的jar包 a. 先在IDEA启动debug b. 然后在终端输入命令：java -agentlib:jdwp=transport=dt_socket,server=n,address=localhost:8081 -jar remote_test-0.0.1-SNAPSHOT-all.jar 5、测试

在准备请求的接口上标记断点

注意：必须先在IDEA启动Debug，然后再启动项目
