nginx-clojure java 集成试用

主要是基于java 开发一个简单的扩展，学习下流程

java 项目

MyApp.java

package com.dalong;
 
import nginx.clojure.java.ArrayMap;
import nginx.clojure.java.NginxJavaRingHandler;
 
import java.io.IOException;
import java.util.Map;
 
import static nginx.clojure.MiniConstants.*;
 
public class MyApp implements NginxJavaRingHandler {
    @Override
    public Object[] invoke(Map<String, Object> map) throws IOException {
        return new Object[] {
                NGX_HTTP_OK, //http status 200
                ArrayMap.create(CONTENT_TYPE, "text/plain"), //headers map
                "Hello, Java & Nginx!"  //response body can be string, File or Array/Collection of string or File
        };
    }
}

运行

基于docker-compose

  • docker-compose 文件
version: '3'
services:
  app: 
     image: dalongrong/nginx-clojure-0.5.3:latest
     volumes: 
     - ./nginx.conf:/usr/local/nginx/conf/nginx.conf
     - ./appjars:/opt/appjars
     ports:
     - 80:80
  • nginx.conf
###you can uncomment next two lines for easy debug
###Warning: if master_process is off, there will be only one nginx worker running. Only use it for debug propose.
 
#daemon  off;
 
#master_process  off;
 
user  root;
worker_processes  1;
 
#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;
 
#pid        logs/nginx.pid;
 
 
events {
    worker_connections  1024;
}
 
 
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
    #gzip  on;
    jvm_path auto;
    ### Set my app jars and resources, it must include nginx-clojure runtime jar,e.g. nginx-clojure-0.5.3.jar and 
    ### for clojure user clojure runtime jar is also needed.
    ### See http://nginx-clojure.github.io/directives.html#jvm_classpath
    # 添加自定义classpath
    jvm_classpath "libs/*:jars/*:/opt/appjars/*";
 
    ###jvm heap memory

    #jvm_options "-Xdebug";
    #jvm_options "-Xrunjdwp:server=y,transport=dt_socket,address=840#{pno},suspend=n";
 
    ###threads number for request handler thread pool on jvm, default is 0.

    server {
        listen       80;
        server_name  localhost;
        location / {
            root   html;

        location = /50x.html {
            root   html;
        }
       # 自己开发的java 方法
       location /dalongdemo {
          content_handler_type 'java';
          content_handler_name 'com.dalong.MyApp';
       }
       location /clojure {
          handler_type 'clojure';
          handler_code ' 
                        (fn[req]
                          {
                            :status 200,
                            :headers {"content-type" "text/plain"},
                            :body  "Hello Clojure & Nginx!" 
                            })
          ';
       }  
    }
}
  • 运行效果

 

 

说明

nginx-clojure 很不错，而且很强大，对于nginx 的扩展开发我们又多了一种可选的方法
