配置

1. 解压源码
   我是解压到：D:\work\project\learn\ 下apache-tomcat-8.5.38-src

2. apache-tomcat-8.5.38-src目录下添加pom文件

    4.0.0
    org.apache.tomcat
    Tomcat8.0
    Tomcat8.0
    8.0
   
    
        Tomcat8.0
        java
        test
        
            
                java
            
        
        
            
                test
            
        
        
            
                org.apache.maven.plugins
                maven-compiler-plugin
                2.3
                
                    UTF-8
                    1.8
                    1.8
                
            
        
    
   
    
        
            junit
            junit
            4.12
            test
        
        
            org.easymock
            easymock
            3.4
        
        
            ant
            ant
            1.7.0
        
        
            wsdl4j
            wsdl4j
            1.6.2
        
        
            javax.xml
            jaxrpc
            1.1
        
        
            org.eclipse.jdt.core.compiler
            ecj
            4.5.1
        
    
   

3. 在apache-tomcat-8.5.38-src 同级目录新建 catalina-home并保证目录下面文件如下
   
   注意： 上面文件夹 apache-tomcat-8.5.38-src里面有的，就剪切过来，没有的就新建一个 bin conf webapps 应该是从apache-tomcat-8.5.38-src剪切过来的

4. idea引入项目
   File->Open 选择解压的D:\work\project\learn\ apache-tomcat-8.5.38-src
   

5. 导入pom文件
   
   

配置启动

1. MainClass: org.apache.catalina.startup.Bootstrap
2. VmOptions: -Dcatalina.home=“D:\work\project\learn\catalina-home”
   
   点击启动按钮

启动报错

1. TestCookieFilter 报错找不到这个类CookieFilter
   解决方法：
   1. 删除：TestCookieFilter
   2. 在test/util下面添加 CookieFilter

           }
   
           return cookieValue;
       }
   }
   
   

2. 启动后，访问localhost:8080 报错 org.apache.jasper.JasperException: java.lang.NullPointerException
   解决方案：
   org.apache.catalina.startup.Bootstrap 添加代码块

   
       {
           JasperInitializer initializer =new JasperInitializer();
       }
   

   

访问

1. 访问 localhost:8080

   

感想

1. 已经够详细了，亲测可以了
