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

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

};

基于docker-compose

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

###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 "-Xms1024m";

    #jvm_options "-Xmx1024m";

    #for enable java remote debug uncomment next two lines

    #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.

    ###check more details from

    #jvm_workers 8;

    server {

        listen       80;

        server_name  localhost;

        location / {

            root   html;

            index  index.html index.htm;

        error_page   500 502 503 504  /50x.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!"

})

';

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
