IDEA部署Tomcat源码并运行

素颜马尾好姑娘i 2022-12-20 14:55 161阅读 0赞

首先，Tomcat官网[源码下载][Link 1]

--------------------

启动IDEA，创建一个空的JAVA工程，找到创建好的这个工程的磁盘目录，将下载后的Tomcat源码复制到工程之下解压后删除即可

--------------------

操作目录：添加一个`home`文件夹（名字自定义）：将原始的`webapps`和`conf`目录放入其中,并创建`pom.xml`文件

**pom.xml文件**

--------------------

创建好的工程导入Tomcat源码： 编辑配置

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQxODU3OTU1_size_16_color_FFFFFF_t_70_pic_center 1]  
主要2,3步骤：  
第二步：找到`org.apache.catalina.startup.Bootstrap`这个类（路径已给）  
第三步配置VM参数：home必须是自己项目路径，继续下一步即可

-Dcatalina.home=F:/CrackingSoftware/tom/apache-tomcat-8.5.42-src/home
    -Dcatalina.base=F:/CrackingSoftware/tom/apache-tomcat-8.5.42-src/home
    -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager
    -Djava.util.logging.config.file=F:/CrackingSoftware/tom/apache-tomcat-8.5.42-src/home/conf/logging.properties

直接DEBUG一下，出现`TestCookieFilter`测试类错误，正常现象，直接注释错误代码即可

之后输入`localhost:8080`页面会出现500错误，

--------------------

需要在源码上面手动初始化JSP解析器：  
找到类`org.apache.catalina.startup.ContextConfig`,在`webConfig();` (快速查找快捷键：Ctrl+F)添加代码：

context.addServletContainerInitializer(new JasperInitializer(), null);

之后刷新页面就可以访问了
