Tomcat7源码环境搭建

Love The Way You Lie 2022-07-18 04:19 192阅读 0赞

### 一、下载Tomcat7源码 ###

从官网上下载Tomcat源码，   http://mirror.bit.edu.cn/apache/tomcat/tomcat-7/v7.0.70/src/apache-tomcat-7.0.70-src.zip

下载之后，将源码解压后重名为tomcat-src，放在E盘的tomcat7目录下.

###  二、安装Ant ###

因Tomcat源码需要ant编译，所以需要安装Ant，从官网下载后解压，并配置环境变量即可.

### 三、安装JDK6 ###

tomcat7的编译需要JDK6的环境，JDK7以及以上,ant 编译时会报错.

### 四、用Ant工具编译Tomcat源码 ###

打开cmd命令行工具，进入tomcat源码目录，输入ant  ide-eclipse ，然后按下Enter键，会自动下载编译需要的依赖包.

可以看见，编译报错了，是因为从国外网站下载依赖的objenesis-1.2-bin.zip超时了，导致编译失败.

解决办法，翻墙下载objenesis-1.2-bin.zip文件，这里为了方便，为大家提供了下载地址：http://pan.baidu.com/s/1kUWtA8v

将其解压后放在C:\\Users\\yulei\\tomcat-build-libs 目录下面

再次运行ant  ide-eclipse 命名就会编译成功了

![20160905223917199][]

编译成功后，会生成Eclipse的项目文件(.classpath等),如下图：

![Center][]

### 五、将Tomcat7源码导入MyEclipse ###

导入MyEclipse后，工程上面会出现红色感叹号.

![20160905224628829][]

打开MyEclipse的Problems视图，可以看到如下错误：

解决方案：右键tomcat工程,Build Path--->Configure Build Path

![Image 1][]

![20160905225237051][]

如上图，以Ant举例，图示操作，点击ant  ，然后点击Edit..    ，若没有，需要自己新建一个.

![20160905225656274][]

以此类推，把余下的Tomacat依赖包配置好。TOMCAT\_LIB\_BASE  配置的地址是：C:/Users/yulei/tomcat-build-libs

### 六、运行Tomcat ###

右键Tomcat工程，Run As --->Java Application, 选择Bootstrap.

![Center 1][]

点击OK，出现如下选项：

选择start-tomcat，后命令行出现如下信息：

九月 05, 2016 11:21:21 下午 org.apache.catalina.startup.CatalinaProperties loadProperties
    WARNING: Failed to load catalina.properties
    九月 05, 2016 11:21:21 下午 org.apache.catalina.startup.Catalina load

表示，tomcat服务没有跑起来，别着急，用Ant  deploy一下你的tomcat工程.

deploy成功之后，然后再运行你的tomcat，会出现如下信息，表示Tomcat服务已成功启起来：

访问http://localhost:8080
