骑猪看日落 2023-10-18 14:07 76阅读 0赞

步骤1:

下载源码 Tomcat 8 官网下载：http://tomcat.apache.org/download-80.cgi

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pob3V6aGl3ZW5nYW5n_size_16_color_FFFFFF_t_70][]

步骤2:

进入eclipse 工作空间workspace，创建Tomcat8 文件

下载的zip 文件在其中进行解压：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pob3V6aGl3ZW5nYW5n_size_16_color_FFFFFF_t_70 1][]

步骤3:

将解压后的所有目录文件放到Tomcat8 下

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pob3V6aGl3ZW5nYW5n_size_16_color_FFFFFF_t_70 2][]

步骤4：

在tomcat8 下创建maven项目所依赖的pom.xml文件，文件内容如下

<?xml version="1.0" encoding="utf-8"?>  
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

步骤5 :

打开eclipse ，以maven 项目形式导入工程

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pob3V6aGl3ZW5nYW5n_size_16_color_FFFFFF_t_70 3][]

步骤 6：

更新maven依赖，启动源码

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pob3V6aGl3ZW5nYW5n_size_16_color_FFFFFF_t_70 4][]

步骤7：

启动日志的输出，浏览器进行访问，验证启动效果

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3pob3V6aGl3ZW5nYW5n_size_16_color_FFFFFF_t_70 5][]

解决：Bootstrap 启动时。

提示：Servlet.service() for servlet \[jsp\] in context with path \[\] threw exception \[java.lang.NullPointerException\] with root cause  
java.lang.NullPointerException  
at org.apache.jsp.index\_jsp.\_jspService(index\_jsp.java:427)

错误说明：tomcat 默认项目ROOT 缺少jsp 标签解析类。我把tomcat8容器源码已经全部导入,但还是提示文件tomcat 依赖的jar文件找不到。

解决版本:找到对应tomact 版本，拷贝器lib 文件夹复制到tomcat 源码/webapp/ROOT/WEB-INF.如截图所示：
