一、背景
为什么要固定部署顺序呢？
由于目前的工程越来越复杂，Web 工程间也存在依赖关系。如果存在 a，b，c 三个工程（同 Tomcat），a 启动时需要访问 b，c 的 RESTful 接口才可以正常部署（a 启动时要访问某些业务）。这时就有出现部署顺序的问题。
Tomcat 7 中默认是不支持自定义独立 Context 配置文件部署顺序的。
二、分析
通过分析 Tomcat 源码，可以发现就是采用 File.list 方法来获得子文件的，不同操作系统无法确定顺序，也无法指定顺序。
见 org.apache.catalina.startup.HostConfig#deployApps()
protected void deployApps() {
File appBase = appBase();
File configBase = configBase();
String[] filteredAppPaths = filterAppPaths(appBase.list());
// Deploy XML descriptors from configBase
deployDescriptors(configBase, configBase.list()); //注意这行，就只使用了 File.list 方法获取子来文件
// Deploy WARs
deployWARs(appBase, filteredAppPaths);
// Deploy expanded folders
deployDirectories(appBase, filteredAppPaths);
}我是否可以重写 HostConfig 来达到我的目的呢？在研究扩展的同时也研究如何让 Tomcat 识别我改写的 HostConfig。
最终我发现可以修改 server.xml 配置文件来加载我改写的 HostConfig 类，从而实现了部署顺序的自定义。（hostConfigClass 属性）
三、实现程序
1、样例项目结构
context-deploy-order 为主功能程序（jar），context-parent 为父 POM，context-tomcat-dist 为打 zip 样例包工程，context-web-a/b/c 为模拟 Web 应该。
a 应用中定义了一个 Listener，启动时访问 b，c 应用的页面并取值。
2、POM 文件
pom.xml(context-parent)
4.0.0
org.noahx.tomcat
context-parent
pom
1.0.0-SNAPSHOT
../context-deploy-order
../context-web-a
../context-web-b

org.noahx.tomcat
context-parent

../context-parent/pom.xml
context-deploy-order

provided
3、主功能程序（org.noahx.tomcat.ContextDeployOrderHostConfig）
该程序会从 context-deploy-order.properties 读取部署顺序。

4、context-deploy-order.properties（-dist 工程中 src/install/misc/conf/context-deploy-order.properties）
b.xml=1
c.xml=2
a.xml=35、server.xml（-dist 工程中 src/install/misc/conf/server.xml）
只需要增加 hostConfigClass 属性
6、Web a 中的 Listener（调用 b，c 中 HTTP 内容）
package org.noahx.tomcat.web.a;
import org.apache.commons.io.IOUtils;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.slf4j.impl.SimpleLogger;
import javax.servlet.ServletContextEvent;
import javax.servlet.ServletContextListener;
import java.io.IOException;
import java.io.InputStream;
import java.net.HttpURLConnection;
import java.net.MalformedURLException;
import java.net.URL;
/**
* Created by noah on 3/17/15.
*/
public class StartupListener implements ServletContextListener {
static {
System.setProperty(SimpleLogger.DEFAULT_LOG_LEVEL_KEY, "INFO");
}
public static final String BASE_URL = "http://127.0.0.1:8080";
private final Logger logger = LoggerFactory.getLogger(this.getClass());
@Override
public void contextInitialized(ServletContextEvent sce) {
int b = getPingValue("/b/ping.jsp"); //ping.jsp 内容 123
int c = getPingValue("/c/ping.jsp"); //ping.jsp 内容 235
if (b != -1 && c != -1) { //访问依赖 web 成功
logger.info(">>> b={} c={} OK.", b, c);
} else {//访问依赖 web 失败
logger.error(">>> b={} c={} ERROR!", b, c);
}
}
/**
* 获得 ping.jsp 页面中的 int 值
*
* @param urlStr
* @return
*/
private int getPingValue(String urlStr) {
int result = -1; //失败 -1
try {
URL url = new URL(BASE_URL + urlStr);
HttpURLConnection urlConnection = (HttpURLConnection) url.openConnection();
urlConnection.setConnectTimeout(10000); //10s 连接超时
urlConnection.setReadTimeout(10000); //10s 读取超时
urlConnection.connect();
if (urlConnection.getResponseCode() == HttpURLConnection.HTTP_OK) { //服务正常
InputStream inputStream = null;
try {
inputStream = urlConnection.getInputStream();
String s = IOUtils.toString(inputStream, "UTF-8").trim();
result = Integer.valueOf(s);
} finally {
IOUtils.closeQuietly(inputStream);
}
}
} catch (MalformedURLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return result;
}
@Override
public void contextDestroyed(ServletContextEvent sce) {
}
}四、打样例包
在 context-parent 目录中执行，mvn clean package，会生成 context-tomcat-dist/target/context-tomcat-dist-1.0.0-SNAPSHOT.zip 文件。
ZIP 文件中有 tomcat1，tomcat2 两个 tomcat 配置。两 Tomcat 的 context 配置文件全在 conf/Catalina/localhost/ 目录下。
tomcat1 是采用上文提供的程序与配置来固定 a，b，c 部署顺序的。conf/server.xml 被替换，在 lib 中增加了 context-deploy-order-1.0.0-SNAPSHOT.jar 与 context-deploy-order.properties。其它与 tomcat2 并无差异。
tomcat2 是原生 Tomcat 没有做任何处理。
五、效果
tomcat1 部署成功，tomcat2 部署失败
1、tomcat1（成功）
